The longest cold snap in years is right now descending upon us from the northwest. It's still a tolerable -5°C at Inner Drive Technology WHQ, but this forecast, man... It looks like temperatures will dip below -17°C (0°F) around 2am tonight and stay there until 7am Saturday, bottoming out around -22°C (-7°F) right before dawn tomorrow.

I'm David Braverman, this is my blog, and Cassie is my 7½-year-old mutt. I last updated this About... page in March 2021. Quite a lot has changed since then, most notably I wrote a whole new blog engine. (More on that in a moment.)

First, just a reminder: anthropogenic climate change (aka global warming) will not wipe out humanity; but it will lead to millions of deaths, plus immense costs and disruptions, which the next few generations will bear. And we could have prevented it. Another reminder: despite what this map shows, as soon as the first real cold of the 2025-26 winter hits after Thanksgiving, lots of people will say "this disproves global warming." No, climate theory predicts weather extremes with the average temperature...

I took the dramatic beagle and Cassie to Spiteful* yesterday afternoon. Butters got more pats than Cassie did. Perhaps it's this face? This afternoon we took a half-hour walk through the local park because the weather is absolutely perfect. Whenever I stopped to try to photograph the two dogs, they immediately went in separate directions, so this is the best I could do: The girls are now sunning themselves on my front porch, I'm up in my office coding away, and I've got chicken soup going in the slow...

I had a long day of debugging today, and I'm about to go to Cassie's doggie daycare the way I got here: on a Divvy e-bike. They cruise at 31 km/h and cost only $2 more than the train for my commute. Plus, I get some aerobic exercise. The forecast calls for summer-like weather through the next few weeks, except for a 3-day cooldown next week, so I'll keep pedaling. And yes, I wore a helmet. Tomorrow: my 5th marathon walk—in 30°C weather.

I just got back from a 30-minute walk with Cassie in 22°C early-autumn sun. We suffered. And now I'm back in my home office and she's back on the couch. She will spend the next several hours napping in a cool, breezy spot downstairs, and I will...work. I will also read a bit, which is a skill that I'm glad Cassie does not have after encountering the day's news: It's official! The June jobs report showed a decline in US employment for the first time since December 2020, making President Biden the only...

As I mentioned in previous posts, Cassie got not one but two long walks over the weekend. On Friday we did a 5½ km loop around the neighborhood and wound up at Begyle for one beer (or a handful of liver treats, depending on species). And yesterday we drove out to Morton Arboretum and did a winding 8½ km loop with Cassie's friend Kelsey. Pity about the weather: Today's weather is about the same, but alas Cassie and I have only gotten 45 minutes of walkies so far. Between work and the first chorus...

A total lunar eclipse has just started and will reach totality at 12:30 Chicago time, which is unfortunately about 10 hours too early for us to enjoy it here. It's a good way to end the first day of meteorological autumn, though, as is the 8 km walk Cassie and I have planned around 2 this afternoon. With a forecast high of 19°C, it should be lovely. In other eclipses this past week: The OAFPOTUS has so badly damaged US foreign policy and our standing in the world that China has eclipsed us as the de...

Cassie got another two hours of walkies yesterday, and we're planning another few hours tomorrow. Today, though, I really need to finish the project I started in June, and I'm digesting half a rack of ribs. So Cassie will only get an hour or so today. If you have half an hour, listen to this talk Cory Doctorow gave in April, which explains why you hate all of the tech you use regularly (except the Daily Parker):

Almost as forecast, the temperature last night went down to 11.4°C at Inner Drive Technology WHQ and 8.9°C at O'Hare, in both cases the coolest since June 2nd and June 1st, respectively. That gets my house to a very comfortable sleeping temperature. The next few nights should continue the trend. Also, it's been exactly* five years since I set out on my first marathon walk. Tomorrow might have turned out to be a really good day to repeat the effort, but I have a lot to do and I'm having a birthday dinner...

A few weeks ago I gathered up the dewpoint statistics for Inner Drive Technology WHQ to show that, yes, this summer really sucked. I promised the final numbers after summer officially ended Sunday night, and here they are: Jun 1 to Aug 31 (UTC) 2024 2025 Avg temperature 22.6°C 23.1°C Avg dewpoint 17.9°C 18.7°C (June) 16.8°C 16.8°C (July) 18.9°C 20.8°C (August) 18.4°C 18.4°C Total days dewpoint ≥ 20°C 27 42 Total readings dewpoint ≥ 20°C 3,791(33.5%) 5,856(45.0%) Total readings 11,317 13,009 The average...

After a lovely weekend that included not one but two long walks with Cassie, not to mention the only baseball game I've attended this season and what is likely to be the last of 10 consecutive days and nights with the A/C off and the windows open, work has returned. I'm mulling a number of different topics to attack this month, but first I have to finish the massive storage locker reorganization I began June 15th. I'm happy to say it looks like I'll have reduced the volume of my own and my mom's things...

The temperature at Inner Drive World HQ bottomed out at 14.6°C at 6:35 this morning. It was last this cool on June 5th at 8:18 CDT, just under 81 days ago. I like summer, I really do. And I recognize that the overnight low at O'Hare this morning (12.8°C) was a bit below normal for August 25th (17.8°C). Still, I didn't sleep with the windows open for 22 days, which may be a (summer) record. That's too long. The next few days should remain unseasonably (but delightfully) cool before it gets warm again...

As I showed yesterday, this summer we've had significantly higher temperatures and dewpoints than last summer. Finally, around 8 this morning, the dewpoint dropped below 20°C and has kept dropping, while the temperature peaked at 23.4°C just after 1: The dewpoint is now 17.7°C, which feels so much better than 20°C that I almost feel giddy. Autumn begins in 10 days. This is a lovely preview.

I have grumbled and complained a lot this summer about the dewpoint, and it turns out I was right all along. Examining over 23,600 readings from Inner Drive Technology World HQ's weather station from 2024 and 2025, I found the following: Jun 1 to Aug 21/19 (UTC) 2024 2025 Avg temperature 22.6°C 23.5°C Avg dewpoint 17.9°C 19.2°C (June) 16.8°C 16.8°C (July) 18.9°C 20.8°C (August) 18.4°C 20.5°C Total days dewpoint ≥ 20°C 27 41 Total readings dewpoint ≥ 20°C 3791 5624 Total readings 11317 11317 This is an...

I have a chunk of work to do this afternoon, but I'm hoping I can sneak in some time to read all of these: Dan Rather cheers on the Democratic Party for finally finding the fight. Francis Fukuyama says: move over Berlusconi; the Clown Prince of X has done considerably more to harm Western civilization than you ever did. David Daley puts responsibility for the exploding fight over Congressional maps squarely on US Chief Justice John Roberts. Jennifer Rubin wants us to stop using the word "guarantee" when...

The temperature at Inner Drive Technology World HQ has passed 32°C (with a 42°C heat index!) and it keeps going up. Welcome to the summer heat advisory season, with 30 million hectares of maize corn sweating to our west. Speaking of an uncomfortable atmosphere, the OAFPOTUS and his droogs have had a bad couple of days, which they responded to by making everyone else's days bad as well. First, on yesterday the US Court for the District of New Jersey declined to allow acting US Attorney Alina Habba (whom...

Like yesterday, today I took Cassie somewhere she'd never been before, giving her an amazing array of new smells and rodents to chase. We went up to the Green Bay Trail in Winnetka, covering just under 5 km, and passing a somewhat-recognizable house along the way: We'll spend more time outside today, though it really hasn't warmed up yet (current temperature: 15°C). She doesn't mind.

I completed two surveys related to my work conference this week. The first one included the question, "To confirm that you are still reading this, please select 'Disagree.'" The second one assigned point values to the multiple-choice questions, so that the three items I answered "Somewhat OK" instead of "Excellent" brought my grade down to a B-minus. These are the kinds of things that make one wonder how valuable the survey data really is. Meanwhile, I've got a ton of things to do today, including...

Before getting to the weather, I don't anticipate any quiet news days for the next couple of years, do you? Someone who owns at least 16 rooms and condos in the OAFPOTUS's Wabash Ave. building in downtown Chicago has sued, alleging that—wait for it—the organization running the building is bilking investors. I mean, how preposterous! Speaking of corruption flowing from the OAFPOTUS like toxic waste from a Union Carbide plant, Molly White mourns the end of SEC oversight of the crypto industry. Former US...

As threatened promised, I'm starting to beg for money to help support The Daily Parker and Weather Now. You can go to Patreon and sign up to help us, with special member benefits as you contribute more. The Daily Parker costs about $5 a day to run (though I hope to reduce that significantly this fall), and Weather Now costs another $10. They're not entirely labors of love, as I have used Weather Now as a demo project to land new work. But after more than five years with the same full-time employer...

Weather Now v5.0.9194 just hit the hardware, with a new feature that allows you to browse the Gazetteer by finding all the places near a point. (Registration required.) I also added a couple of admin features that I will propagate to every other app I have in production, and made a few minor bug fixes. Only one minor hiccup: I forgot to add a spatial index to the Gazetteer, which caused searches around a point to take minutes instead of seconds in production. I added the index to the database...

By yesterday evening I managed to import all the National Geospatial-Intelligence Agency country place data through the Bs. This morning, I couldn't get to the NGIA website. All right, sometimes these things happen. No biggie. Yet, knowing a little about how the OAFPOTUS and Clown Prince Elon have operated the last 30 days, I did some digging. And I discovered yet another example of how imbecilic these infants are. Simply: someone has removed the agency from the Internet. All DNS records for the agency...

It got a lot warmer in Chicago today: That's the normal high for February 25th, one month from now. O'Hare got up to 5°C, the normal high for March 1st. We also have 62 km/h wind gusts, so it really does feel a lot like the beginning of spring. We're supposed to get up to 7°C on Monday (March 10th), which is practically tropical for this time of year. We'll take it!

I've been working on a long-overdue update to Weather Now's gazetteer, the database of places that allows people to find their weather. The app uses mainly US government data for geographic names and locations, but also some international sources. This matters because the US government has a thing called "Geopolitical Entities and Codes (GEC)," which superseded Federal Information Processing Standard (FIPS) publication 10-4. Everyone else in the world use International Standards Organization publication...

Item the first: Weather Now got an update today. Under the hood, it got its annual .NET version refresh (to .NET 9), and some code-quality improvements. But I also added a fun new feature called "Weather Score."  This gives a 0-to-100 point value to each weather report, showing at a glance where the best and worst weather is. A perfect day (by my definition) is 22°C with a 10°C dewpoint, light winds, mostly-clear skies, and no precipitation. The weather at O'Hare right now is not, however, perfect, and...

It's New Years Eve, so it's time for the Chicago Sunrise Chart for 2025. Other end-of-year and beginning-of-year posts will dribble out today and tomorrow.

The temperature in my neighborhood fell below freezing around 4am and kept dropping, bottoming out just a few minutes ago at -1.7°C, the coldest it's been since March 18th. So despite valiantly holding onto their leaves later in the year than I can remember, the gingko and maple trees around my house finally surrendered to the inevitable: All those leaves fell in the last couple of hours. In fact I tried to get a photo of them just pouring off the tree, but that's hard to capture in a still photo....

Monday's derecho spawned so many tornados in Northern Illinois that the National Weather Service hasn't yet confirmed the paths they all took. But one of those paths got my attention: That's, uh...that tornado ended at the front door of the Ogilvie Transportation Center, where I get off my morning commuter train, which is 300 meters from my office. It went straight down Madison Street from Racine to Canal. That does not usually happen. And yesterday, this one little punk rainstorm dumped almost 10 mm of...

Cassie and I have gone on two walks today, the first for 3.2 km and the second for 4.25 km, despite the really uncomfortable 26°C dewpoint. I mean, it's really gross out there. Fortunately because of the way dogs get rid of excess heat, it didn't bother her as much as it bothered me—the air is only 28°C, after all. But we both felt a lot better when we got back to my air-conditioned house. (Fun fact: my thermostat is set for 25°C, but the dewpoint inside is closer to 15°C which makes all the...

First, let me just say how lovely it was to wake up to this today, especially as we're mere minutes from the earliest solstice since the Washington administration: My windows are open, and I no longer hate the world. Which, it turns out, is a perfectly normal response to high heat: It turns out even young, healthy college students are affected by high temperatures. During the hottest days, the students in the un-air-conditioned dorms, where nighttime temperatures averaged [27°C], performed significantly...

Cassie and I took two long walks yesterday. We drove up to the Skokie Lagoons before lunchtime and took a 7.25 km stroll along the north loop. The weather cooperated: I wanted to go up there in part because a 100-year-old forest had a higher probability of cicadas than anywhere near my house. We were not disappointed. Cassie and I both had passengers at various points in the walk: And wow, were they loud. I forgot how loud they got during the 2007 outbreak. Even at the points on the walk closest to the...

Yesterday saw some really unusual temperatures at IDTWHQ: You don't often see the day's low temperature at 14:16 followed by the day's high at 17:09. That was just weird.  A similar thing happened at Chicago's official weather station, O'Hare, except the temperature bottomed out around 11am and peaked around 5pm. Today it's just gray and seasonably cool. It's a lot easier to pick clothes when the temperature curve is flatter, and goes the way you'd expect.

I'm heading off to a Euchre tournament in a bit. I haven't played cards with actual, live people in quite some time, so I just hope to end up in the middle of the pack. Or one perfect lay-down loner... A guy can dream. When I get home, I might have the time and attention span to read these: John Grinspan looks at the similarities and crucial differences between the upcoming election and the election of 1892. Andy Borowitz jokes about the latest of Robert F Kennedy's conspiracy theories: that his own...

My Garmin watch thinks I've had a relaxing day, with an average stress level of 21 (out of 100). My four-week average is 32, so this counts as a low-stress day in the Garmin universe. At least, today was nothing like 13 March 2020, when the world ended. Hard to believe that was four years ago. So when I go to the polls on November 5th, and I ask myself, "Am I better off than 4 years ago?", I have a pretty easy answer. I spent most of today either in meetings or having an interesting (i.e., not boring)...

The cold front we expected passed over my house around 8:15 last night. I wouldn't call it subtle, either: Even that doesn't get to the truly unsubtle aspects of this frontal passage. The radar image might, though: Not shown: the 60 km/h winds, lashing rain, brilliant lightning show, 5-10 mm hailstones, tornadoes to the northwest and southeast, and a mildly alarmed dog getting pats on the couch. And it keeps getting better this morning. Right now I'm in a Loop high rise gently swaying in the 45 km/h...

What do you get when you combine a 2°C air temperature, a 2°C dew point, frozen ground with snow patches, and nearly-calm winds? Visibility under 100 meters on my commute to the office: They say we may not see the sun until Wednesday. But they also say it'll be 7°C that day. March came early this year, it seems.

I'm watching my plane arriving from Chicago to get all of us going back there on it, a little remorseful that I couldn't spend more time in Seattle. I last visited in 2013 to watch the Cubs hold their own against the Mariners for 9 whole innings, only to lose with no outs in the bottom of the 10th. On that June day Seattle had sunny 30°C weather. This morning we had sunny weather, I'll give it that: But warm? No. In the 38 hours of my trip it only got above -6°C once I got to the airport to go home....

Though my "to-be-read" bookshelf has over 100 volumes on it, at least two of which I've meant to read since the 1980s, the first book I started in 2024 turned out to be Cory Doctorow's The Lost Cause, which I bought because of the author's post on John Scalzi's blog back in November. That is not what I'm reading today at lunch, though. No, I'm reading a selection of things the mainstream media published in the last day: Economic historian Guido Alfani examines the data on the richest people to live...

The El Niño part of the ENSO typically gives Chicago warm, dry winters (relatively—it still gets cold and snowy here, just not as cold and snowy as usual). Exhibit 1, a map of temperature anomalies in the Continental US for the first 12 days of December: I'm about to leave the office to go home, where it's 8°C, after hitting 11°C at O'Hare a couple of hours ago. Tomorrow it might get warmer. And that's OK by me.

We officially had our first freeze last night as the temperature at O'Hare dipped to -1°C. At Inner Drive Technology World HQ it only got down to 0.1°C, barely above freezing, but still cold enough to put on ear muffs and gloves taking Cassie to day camp this morning. It'll warm up a bit this weekend, though. Meanwhile, I'm writing a longer post about propaganda, which I may post today or tomorrow. And that's not the only fun thing happening in the world, either: Ukraine has had a lot of success blowing...

Spot the cold front: I took Cassie for her final walk at 10pm, during the steepest part of that second cliff. The temperature dropped 0.5°C during the 7 minutes it took us to walk around the block. The dewpoint eased off as well, making it actually tolerable for the first time in two days. In a post this morning, the National Weather Service explained how bad we had it for those two days: 8/23 saw the first 80°F dew point observed in Chicago since 7/30/1999 and only the 7th calendar day on record where...

This is why I won't get 10,000 steps today: I'm still at 84,000 steps over the past 7 days, though. Still, even though it's cool enough to have all the windows open, and none of the rain seems to be blowing in, I'd still rather have gotten all my steps today. Cassie, for her part, got over 4 hours of walks this past weekend, so she seems fine with it. She doesn't like the rain any more than I do. Maybe tomorrow.

My phone, watch, and dog are all recharging right now after Cassie and I walked 9.5 km to the Horner Park DFA and back. Right now it's officially 30°C with the occasional wind gust at O'Hare, but here in Ravenswood we've got 26°C with a light breeze. So once my watch has fully charged we're going back outside. And hey, we might see this guy again: Several people have identified this as a Cooper's Hawk, one of the more common raptors in the Illinois prairies, and I hope a more common visitor to my...

Because of yesterday's rain, poor Cassie only got 23 minutes of walkies yesterday—almost all of it in drenching rain. I went through two towels drying her off after each of her walks. And of course, because she was (a) being rained on and (b) couldn't smell anything, it took her way more time than I preferred to find where to do her job. For my part, I really got a close shave on my step count: Today we have blue skies, sun, and a forecast high of 23°C: perfection. (The AQI is down to 47, too.) I have...

Some stories to read at lunch today: The Supreme Court unanimously rejected the US Postal Service's requirement that a religiously observant letter carrier deliver packages on the Sabbath. Since Justice Alito (R$) wrote the opinion, I'll also have to read Justices Sotomayor's (I) and Jackson's (I) concurrence. Of course, as Josh Marshall predicted, the Court split along partisan lines in a decision that essentially abolishes affirmative action for college admissions, which will likely reverse the gains...

As the smoke from Canadian wildfires continues to spread through the American Midwest, I want to mention that the effective use of government regulation of industry has made this week's air quality that much more surprising. Just take a look at Evanston, Ill., yesterday around 7pm: The fact that this looks really weird says a lot about what the government can do when people are behind it. No, really: the air-quality alerts from Minnesota to West Virginia look bizarre right now because we hardly ever see...

Chicago has an air quality alert right now as the World Air Quality Index lists us first (last?) in the world for worst air quality: Canadian wildfire smoke pouring into Chicago has made its air quality the worst in the world Tuesday. The World Air Quality Index ranked Chicago as the worst for air quality, with Dubai, Minneapolis, Jakarta and Doha, Indonesia rounding out the top 5. Chicago’s air is labeled an “unhealthy” 172 by the index. The National Weather Service blamed the conditions and low...

I had a lot going on this morning, so I'm only now snarfing down a Chipotle bowl. Also, I'm going to have to read these things tomorrow: Over 100 candidates, including a dog, will stand for election in Toronto's mayoral election on the 26th. Writing for Mother Jones, Ali Breland thinks the content-creator rebellion at Reddit won't stop what Corey Doctorow calls "the enshittification" of online platforms. Similarly, private-equity debt has killed yet another good company making good products, Insta-Pot....

We've got a cool snap going into its third day here, and despite the 16 hours of daylight, it feels like autumn. But this happens every June. We just forget every year. Coming on the heels of the studies saying I don't need 10,000 steps to stay healthy, I can honestly report I'll stay healthy today without getting 10,000 steps.

Cassie got about 4 hours of walks yesterday, plus about 9 additional hours of outdoor time. I got sunburned. So I didn't have any time to post, but I did have time to get side-eye from this girl: That's Butters, a beagle whose every look is side-eye. It's quite a talent. "If you can spend a perfectly useless afternoon in a perfectly useless manner, you have learned how to live."—Lin Yutang

Sorry, the weather is just too nice to spend time inside writing blog posts. Regular posting resumes tomorrow...or Monday, if tomorrow is like this, too.

Today they got through about half of our flat roof which doubles as an upstairs patio. Imagine how much noise all this made: Note that all the crap on the roof off to my left was at the other end of the balcony while they laid down the material directly under me. They timed it so they had the power saw going exactly when I had a Teams meeting for work. But they did got a lot of it done, and they should reconnect my A/C units just in time for next week's heat wave.

As the wildfires in western Canada continue to burn, we in Chicago continue to live under the smoke plume, going on four days now. NASA's Earth Observatory has art: Raging fires filled the skies of southern Canada and the northern United States with smoke in mid-May 2023. The fires had scorched 478,000 hectares (1,800 square miles) in Alberta, British Columbia, and Saskatchewan, as of May 16, which is 10-times the average area burned for this time of year. As of May 16, there were 87 wildland fires...

We seem to get a lot of pneumonia fronts lately. Here's yesterday's: The temperature at IDTWHQ was 23.5°C at 17:35, 22.6°C at 17:45, 20.9°C at 18:00, and down it went, to 15.9°C by 19:00. (For the Philistines, that's a 14°F drop in 90 minutes.) At about that time, smoke from fires in Alberta combined with rapid condensation aloft (i.e., clouds from the cold front) to give us one hell of a filter for the sun: I used a daylight color temperature (5700K) for that shot so you can see the color I saw. Here's...

The Daily Parker began as a joke-of-the-day engine at the newly-established braverman.org on 13 May 1998. This will be my 8,907th post since 1998 and my 8,710th since 13 November 2005. And according to a quick SQL Server query I just ran, The Daily Parker contains 15,043,497 bytes of text and HTML. A large portion of posts just curate the news and opinions that I've read during the day. But sometimes I actually employ thought and creativity, as in these favorites from the past 25 years: Old Man...

I'm in the desert southwest for a company event. They gave me this (East) view: Since I last visited Phoenix in 2015, they've added a light rail system. It got me from the baggage retrieval carousel at the airport to the hotel (which is by the convention center, pictured above) in 32 minutes, which I appreciate. The first airplane they had us on to get here broke, so I got to Phoenix two hours later than planned, which I did not appreciate. I've got nothing scheduled for the next two hours so I'm going...

Cassie does not like staying inside because of the rain:

Just in time for spring, the City of Chicago has just announced the winning names for seven of our beloved snowplows: Da Plow Holy Plow! Jean Baptiste Point du Shovel Mrs O'Leary's Plow Salter Payton Sears Plower Sleet Home Chicago From the Chicago Tribune: Nearly 7,000 potential names were submitted in 17,000 suggestions from Chicago residents. Initially, the city planned to name six snowplows — one for each snow district — in its fleet of almost 300 baby-blue “Snow Fighting Trucks.” (During a major...

I finished a couple of big stories for my day job today that let us throw away a whole bunch of code from early 2020. I also spent 40 minutes writing a bug report for the third time because not everyone diligently reads attachments. (That sentence went through several drafts, just so you know.) While waiting for several builds to complete today, I happened upon these stories: The former co-CEO of @Properties bought 2240 N. Burling St., one of the only remaining pre-Fire houses in Lincoln Park, so...

It got practically tropical this afternoon, at least compared with yesterday: Cassie and I took advantage of the no-longer-deadly temperatures right at the top point of that curve to take a 40-minute, 4.3 km walk. Tomorrow should stay as warm, at least until the next cold front comes in and pushes temperatures down to -18°C for a few hours Thursday night. I'm heading off to pub quiz in a few minutes, so I'll read these stories tomorrow morning: London plans to build an elevated rails-to-trails park...

It's official. Last month had the lowest percentage of possible sunshine (18%) of any January in history and the second-lowest percentage of any month in history. The month also had more overcast days (18) than all but two of the 1,791 months in the historical record. Only January 1998 (20) and November 1985 (19) had more. (Records go back to October 1871.) One interesting tidbit: 3 of the 5 least-sunny Januarys happened in the last 6 years. But as I write this, there isn't a cloud in the sky. (It's...

I've barely finished my coffee so I'm still processing this amazing news: Monday Sunny, with a high near 2. West southwest wind 10 to 15 km/h increasing to 20 to 25 km/h in the afternoon. Winds could gust as high as 35 km/h. "Sunny." I hope...I hope...I hope... Of course, temperatures will fall below normal for the first time all year by Thursday, and the European Centre for Medium-Range Weather Forecasts believes Chicago has a 31% chance of getting 100 mm of snow by Thursday with most of it falling...

One Daily Parker reader sent me this clarification that the big hole in CA-92 preventing people in Half Moon Bay, Calif., from reaching Silicon Valley is not, technically, a sink hole: The first thing to know about that sinkhole that opened on Highway 92 on Thursday: It’s not a sinkhole: Geologists make a distinction between sinkholes, which require a particular blend of soils — limestone, salts, gypsum and other components — and caverns that appear with water due to engineering failures, aging...

I got a lot done today, mostly a bunch of smaller tasks I put off for a while. I also put off reading all of this, which I will do now while my rice cooks: The EU's Copernicus Climate Change Service determined that 2022 was the fifth-hottest year on record, once again making the last 8 years the hottest on record. As North America sees record warmth and record-low snowfall this winter, we can guess how 2023 will end up. In no small irony, Illinois was actually cooler than normal last year. I've said...

As I look out my office window at the blowing snow accumulating on downtown Chicago streets, I think back to days gone by when we had sunlight. Eight straight days of gray tend to wear on a person. It looks like we'll have sun on Sunday, just before the arctic blast comes through and drives temperatures down to -14°C by Wednesday. This also comes just after Cassie got a perfect bill of health at the vet yesterday—except that she's now 15% overweight. Guess who's getting raw green beans for dinner for...

Between my actual full-time job and the full-time job I've got this week preparing for King Roger, Cassie hasn't gotten nearly the time outdoors that she wants. The snow, rain, and 2°C we have today didn't help. (She doesn't mind the weather as much as I do.) Words cannot describe how less disappointed I am that I will have to miss the XPOTUS announcing his third attempt to grift the American People, coming as it does just a few hours after US Senator Rick Scott (R-FL) announced his bid for Senate...

The South's misfortune is Chicago's benefit this week as a hot-air dome over Texas has sent cool Canadian air into the Midwest, giving us in Chicago a perfect 26°C afternoon at O'Hare—with 9°C dewpoint. (It's 25°C at IDTWHQ.) Add to that a sprint review earlier today, and I might have to spend a lot more time outside today. So I'll just read all this later: The Justice Department and the XPOTUS have gone back and forth about what parts of the Mar-a-Lago search warrant to publicize, with the XPOTUS...

Happy Monday: The XPOTUS uses the same pattern of lies every time he gets caught committing a crime. Jennifer Rubin says this was his dumbest crime yet. Usability experts at the Nielsen/Norman Group lay out everything you hate about phone trees, and how companies could fix them. My generation should be your boss now, but of course, we aren't. Within 30 years, Chicago could experience 52°C heat indexes. I would now like to take a nap, but alas...

Even though I feel like I have a moderate cold (stuffy, sneezy, and an occasional cough), I recognize that Covid-19 poses a real danger to people who haven't gotten vaccinations or who have other comorbidities. So I'm staying home today except to walk Cassie. It's 18°C and perfectly sunny, so Cassie might get a lot of walks. Meanwhile, I have a couple of things to occupy my time: Arthur Rizer draws a straight line from the militarization of police to them becoming "LARPing half-trained, half-formed kids...

It was 30.5°C at 6:09pm and 21.1°C at 7:10pm. At this writing, it's 18.3°C, with thunderstorms approaching from the west. They should hit late tonight. I'm still keeping my windows open.

At 7am Monday, it was 12°C at Inner Drive Technology World Headquarters. By 6pm the temperature had gone up to 26.5°C, then 29.8°C at 2pm Tuesday, then 29.1°C at 3:15pm yesterday, before a cold front finally ploughed through and got us down to lovely sleeping weather right before I turned in: The slow rise in my indoor temperature from 7am to 5pm was just my normal A/C program, as was the decline when the A/C turned on at 5. Then at 6, I discovered that the cold front had gone through, so I opened the...

Thursday evening, at the Harris Theater for Music and Dance: That's Bill Kurtis, Peter Sagal, Karen Chee, Alonzo Bodden, and Helen Hong at this week's "Wait Wait" taping. The "Not My Job" guest was actor Matt Walsh: Then yesterday, Cassie and I trundled up to Spiteful Brewing in the sun: Not a bad few days, in all.

I've just switched the DNS entries for wx-now.com over to the v5 App, and I've turned off the v4 App and worker role. It'll take some time to transfer over the 360 GB of archival data, and to upload the 9 million rows of Gazetteer data, however. I've set up a virtual machine in my Azure subscription specifically to do that. This has been quite a lift. Check out the About... page for the whole history of the application. And watch this space over the next few months for more information about how the app...

This weekend, I built the Production assets for Weather Now v5, which means that the production app exists. I haven't switched over the domain name yet, for reasons I will explain. But I've created the Production Deploy pipeline in Azure DevOps and it has pushed all of the bits up to the Production workloads. Everything works, but a couple of features don't work perfectly. Specifically, the Search feature will happily find everything in the database, but right now, the database only has about 31,000...

Even as the East Coast gets bombed by an early-spring cyclone, we have sunny skies and bitter cold. But the -12°C at O'Hare at 6am will likely be the coldest temperature we get in Chicago until 2023. The forecast predicts temperatures above 10°C tomorrow and up to 16°C on Wednesday, with no more below-freezing temperatures predicted as far out as predictions can go. Meanwhile, I'm about to leave for our first of two Bach Jonannespassion performances this weekend. We still have tickets available for...

No, I didn't send Cassie's slobber to 78AndWoof.com or anything. Someone brought a DNA-shaped toy to the dog park today, which Cassie found irresistible: This cattle dog also found the toy irresistible, leading to this irresistible tug-of-war that ranged around the park for a good five minutes:

The temperature dropped 17.7°C between 2:30 pm yesterday and 7:45 this morning, from 6.5°C to -10.2°C, as measured at Inner Drive Technology World Headquarters. So far it's recovered to -5.5°C, almost warm enough to take my lazy dog on a hike. She got a talking-to from HR about not pulling her weight in the office, so this morning she worked away at a bone for a good stretch: Alas, the sun came out, a beam hit her head, and she decided the bone could wait: Meanwhile, in the rest of the world: Julia...

Other than making a hearty beef stew, I have done almost nothing of value today. I mean, I did some administrative work, and some chorus work, and some condo board work. But I still haven't read a lick of the books I've got lined up, nor did I add the next feature to the Weather Now 5 app. I did read these, though: An Illinois state judge has enjoined the entire state from imposing mask mandates on schools, just as NBC reports that anti-vaxxer "influencers" are making bank off their anti-social...

We only got about 50 mm of snow overnight, but the second wave came in the morning and hasn't stopped. And yet, not everyone cares about the natural disaster unfolding around us: She followed up on her romp this morning by eating my earmuffs. Sigh.

The snow has finally stopped for, we think, a couple of days, and the city has cleared most of the streets already. (Thank you, Mike Bilandic.) What else happened today? The James Webb Space Telescope reached Lagrange-2 this afternoon, and will now settle into a "halo orbit" that will hold it about 1.46 million km from Earth. (It's still traveling at 200 m/s, which gets you from Madison to Peterson in about a minute.) Lord Agnew (Con.), the minister responsible for policing Covid fraud in the UK...

The temperature at Inner Drive Technology World Headquarters bottomed out at -16.5°C around 8am today, colder than any time since February 15th. It's up to -8.6°C now, with a forecast for continued wild gyrations over the next week (2°C tomorrow, -17°C on Monday, 3°C on Wednesday). Pity Cassie, who hasn't gotten nearly enough walks because of the cold, and won't next week as her day care shut down for the weekend due to sick staff. Speaking of sick staff, New Republic asks a pointed question about the...

I've finally resumed progress on a major update to Weather Now. I finished everything except the user interface way back in April, but between summer, Cassie, and everything else, I paused. At least, until last week, when something clicked in my head, and I started writing again. As my dad would say, I broke the code's back. It turns out, the APIs really work well, and I'm getting used to .NET Blazor, so I'm actually getting things done. The only downside applies to Cassie, who will probably only get 90...

While running errands this morning I had the same thought I've had for the past three or so weeks: the trees look great this autumn. Whatever combination of heat, precipitation, and the gradual cooling we've had since the beginning of October, the trees refuse to give up their leaves yet, giving us cathedrals of yellow, orange, and red over our streets. And then I come home to a bunch of news stories that also remind me everything changes: Like most sentient humans, Adam Serwer feels no surprise (but...

Oh boy: Voters have defeated billionaire, populist Czech prime minister Andrej Babiš through the simple process of banding together to kick him out, proof that an electorate can hold the line against strongmen. A school administrator in Texas told teachers that "if they have a book about the Holocaust in their classroom, they should also offer students access to a book from an 'opposing' perspective." Because Texas. Oakland Police should stop shooting Black men having medical emergencies, one would...

While I wait for a continuous-integration pipeline to finish (with success, I hasten to add), working a bit later into the evening than usual, I have these articles to read later: Canadian Prime Minister Justin Trudeau (Lib-Papineau) called a snap election to boost his party, but pissed off enough people that almost nothing at all changed. Margaret Talbot calls out the State of Mississippi on the "errors of fact and judgment" in its brief to the Supreme Court about its draconian abortion law. Julia...

Those topics led this afternoon's news roundup: The Intergovernmental Panel on Climate Change released its 6th periodic report on the state of the planet, and it's pretty grim. But as Josh Marshall points out, "Worried about life on earth? Don’t be. Life’s resilient and has a many hundreds of millions of years track record robust enough to handle and adapt to anything we throw at it. But the player at the top of the heap is the first to go." Charles Blow has almost run out of empathy for people who...

While I look out my hermetically-sealed office window at some beautiful September weather in Chicago (another argument for working from home), I have a lot of news to digest: The infrastructure bill unveiled in the US Senate this morning would give $66 billion to Amtrak, which desperately needs the money. Josh Marshall argues that social-group identity drives resistance to vaccination. Brooke Harrington elaborates by pointing out that people who are conned usually can't admit to being conned. In...

Just a couple of articles that caught my interest this morning: Penn State climate scientist Michael Mann warns us "the signal of climate change has emerged from the noise." The BBC examines the cost of hosting the Olympics, as The Economist wonders whether cities should bother hosting them. New Republic reviews a book by John Tresch about Edgar Allan Poe's—how does one say?—farcical and tragic misunderstanding of science. Eugene Williams finally got a monument yesterday, at Lincoln Cemetery in Blue...

At the moment, the 10 hottest places in the world are all in the Pacific Coast states and British Columbia. The Dalles, Ore., hit 48°C at 4pm Pacific; Portland hit 46°C, the same as Palm Springs, Calif.; and even Lytton, B.C., reports 46°C right now—the highest temperature ever recorded in Canada. All of those figures exceed yesterday's forecast and broke all-time records set just yesterday. It's bonkers. And it won't be the last time this happens. Here in Chicago we have a perfectly reasonable 26°C....

Yesterday I squashed six bugs (one of them incidentally to another) and today I've had a couple of good strategy meetings. But things seem to have picked up a bit, now that our customers and potential customers have returned to their offices as well. So I haven't had time to read all of these (a consistent theme on this blog): An early-summer heat dome has formed over a larger area than expected, pushing temperatures in the Southwest US as high as 53°C in places. Lenore Skenazy, who founded the...

So far today, Cassie and I have taken 2½ hours of walks, and she's taken about twice that in naps while I read in the sunroom with a nice breeze blowing over me. In other words, nothing to blog about today.

The northern hemisphere started meteorological summer at midnight local time today. Chicago's weather today couldn't have turned out better. Unfortunately, I go into the office on the first and last days of each week, so I only know about this from reading weather reports. At my real job, we have a release tomorrow onto a completely new Azure subscription, so for only the second time in 37 sprints (I hope) I don't expect a boring deployment. Which kind of fits with all the decidedly-not-boring news that...

I confess to some difficulty talking to people who exhibit willful irrationality. If you don't want to wear a mask or get a vaccine because you somehow equate that with a political party, I don't know what to tell you. But for the people who may just have some irrational fear without making a political statement about it, the New York Times has a helpful interactive training article for you. In other news, an iceberg slightly larger than Long Island broke away from Antarctica this week. So that's fun.

The wind shifted abruptly just before 6pm last night by my house, bringing with it a remarkable drop in temperatures. I live about 1½ km from Lake Michigan, which (with Lake Huron, hydrologically the same body of water) is the second-largest fresh-water lake in the world. In the summer, it keeps Chicago cool. In the winter, it keeps Chicago warm. In the spring, it keeps Chicago paying attention to the weather forecast. Exhibit 1, temperatures near O'Hare at 6pm yesterday. Note the 13.3°C gap between...

Sunday evening we had 4°C gloominess with gusty winds. Today we've got 28°C sunniness with gusty winds. We've also got a bunch of news stories to glance through while a build completes: The US Centers for Disease Control and Prevention has issued new guidance about the relative safety of various activities given vaccines and masks (see chart below). On this day 500 years ago, Ferdinand Magellan died when he got involved in an internecine dispute in the Philippines. Climate change will increase flood...

Happy 51st Earth Day! In honor of that, today's first story has nothing to do with Earth: The MOXIE experiment on NASA's Perseverance rover produced 5.4 grams of oxygen in an hour on Mars, not enough to sustain human life but a major milestone in our efforts to visit the planet. Back on earth, the Nature Conservancy has released a report predicting significant climate changes for Illinois, including a potential 5°C temperature rise by 2100. Microsoft has teamed up with the UK Meteorological Office (AKA...

Some stories in the news this week: The Muldrow Glacier in Denali National Park began to surge a few months ago and has accelerated to almost 30 meters per day. Chicago-area transit agencies believe that about 20% of former transit riders won't come back after Covid, leading them to re-think their long-range planning. The IRS will begin sending parents a monthly payment that replaces the annual child tax credit starting in the beginning of July. Guess what? Whether intentionally or not, the XPOTUS's...

Even though my life for the past week has revolved around a happy, energetic ball of fur, the rest of the world has continued as if Cassie doesn't matter: US Senator Ron Johnson (R-WI) has taken the lead in spewing right-wing conspiracy bullshit in the Senate. Retired US Army Lt Colonel Alexander Vindman joins Garry Kasparov in an op-ed that says it's not about the individual politicians; Russia's future is about authoritarianism against democracy. Deep waters 150 meters under the surface of Lake...

Chicago got up to 21°C yesterday, tying the record for March 9th set in 1974. It's already 20°C right now, close to the record 22°C set in 1955. In other news: One chart shows the difference between the XPOTUS's 2017 tax cut for rich people and President Biden's pandemic-relief bill, which he will sign into law tomorrow. Lou Ottens, who invented the audio cassette tape, died at the age of 94. A survey of Windows computers found that 26% of them have not applied the WannaCry patch after four years of...

I've already done 8 km of walks this morning, and tomorrow I'm doing another 9. (Tomorrow's will end at Sketchbook Brewing, so I'll be even more motivated.) After being cooped up at home and forced to get my daily steps bundled up like the Michelin Man for a few weeks, I feel a bit liberated. The sidewalks are almost all clear (except for a few buildings whose owners suck, like the Cagan Management-run apartments near me), it's already 8°C outside, and the sky is crystal-clear. Tomorrow we might get a...

I want this, right now: But this is what I've got, right now: The forecast, which includes a winter storm warning, calls for lake-effect snow continuing through tomorrow morning with accumulations of around 30 cm. Oh, and it's -14°C out there. I may not get to 10,000 steps today. Note that the top photo shows a typical February 14th in St Maarten.

The December solstice happened about 8 hours ago, which means we'll have slightly more daylight today than we had yesterday. Today is also the 50th anniversary of Elvis Presley's meeting with Richard Nixon in the White House. More odd things of note: Former Justice Department Office of Legal Counsel attorney Erica Newland has some regrets. Congress finally passed a $900 million stimulus bill that has no real hope of stimulating anyone who's unemployed or about to lose his home. Nice work, Mitch. Canada...

To thoroughly depress you, SMBC starts the week by showing you appropriate wine pairings for your anxiety. In similar news: Illinois House Speaker Michael Madigan (D-Chicago) seeks a 19th term as Speaker, but new Federal indictments and that people voted against Democrats statewide because they don't want him around anymore have made his bid unlikely. Vermont and South Dakota have similar demographics and both have Republican governors, so how did Vermont keep Covid-19 infections low while South Dakota...

The first polls close in the US next Tuesday in Indiana at 6 pm EST (5 pm Chicago time, 22:00 UTC) and the last ones in Hawaii and Alaska at 7pm HST and 8pm AKST respectively (11 pm in Chicago, 05:00 UTC). You can count on all your pocket change that I'll be live-blogging for most of that time. I do plan actually to sleep next Tuesday, so I can't guarantee we'll know anything for certain before I pass out, but I'll give it the college try. Meanwhile: The US Senate confirmed Amy Coney Barrett to the...

Just a few of the things that crossed my desktop this morning: Astronomers have detected phosphine gas in the clouds on Venus, which is a strong indicator of life. Astronomers have also detected a ping-pong-ball-sized black hole orbiting the sun, getting as close as 133 kAUs in its orbit. An aircraft made a precautionary landing on an Interstate in Tennessee, and got a full police escort on take-off. No one was hurt. Car manufacturers are teaming up with insurance companies to share data on almost every...

As of Saturday, it looked like we might break the record for hottest summer ever (average daily temperature 24.7°C) in Chicago, set way back in 1955. If the today's forecast holds, however, we will merely tie the record. This is actually a good-news, bad-news thing. The good news is: (a) we came just a bit short of breaking the record (36.7°C) for August 26th, and (b) a cold front will push through tomorrow evening, dropping temperatures into the high 20s for the weekend. You know? I'm OK with not...

Geographer Randy Cerveny heads up an ad hoc committee of the World Meteorological Organisation tasked with validating weather records: Since 2007, Cerveny has been in charge of organizing ad hoc committees to independently verify superlative weather measurements — such as the highest ocean wave or the strongest wind gust. Now, when a new contender for a record appears, he gathers the top experts in any given subject. "If we're looking at temperature, I'm going to get some of the best scientists that...

I'm taking a day off, so I'm choosing not to read all the articles that have piled up on my desktop: Tropical Storm Josephine has formed east of the windward islands, becoming the earliest 10th named storm on record. The National Hurricane Center promises an "extremely active" season. By tracking excess deaths in addition to reported Covid-19 deaths, the New York Times has concluded we've already surpassed 200,000 and could hit half a million by the end of the year. The General Accounting Office, a...

It has cooled off slightly from yesterday's scorching 36°C, but the dewpoint hasn't dropped much. So the sauna yesterday has become the sticky summer day today. Fortunately, we invented air conditioning a century or so ago, so I'm not actually melting in my cube. As I munch on some chicken teriyaki from the take-out place around the corner, I'm also digesting these articles: James Fallows points to the medieval alcohol-distribution rules in most states as the biggest threat to craft brewing right now....

Today's interesting and notable news stories: This week marks the 25th anniversary of Chicago's deadly heat wave in July 1995, during which 700 people died and we hit a record 41°C with a 52°C heat index. Watergate prosecutor Nick Akerman sees the Trump Administration's corruption as far worse than Nixon's. In a recent interview with CNN, Education Secretary Betsy DeVos repeated, without coherently explaining the how or why of it, that children should go back to school this fall. DeVos'...

As I take a minute from banging away on C# code to savor my BBQ pork on rice from the local Chinese takeout, I have these to read: President Trump once again said the quiet part out loud, announcing he plans to gut fair-housing rules because otherwise they would "have...a devastating impact on these once thriving Suburban areas." The Supreme Court will hear arguments whether the House can have access to Robert Mueller's unredacted report—in the fall. Josh Marshall goes over the "ominous and harrowing"...

Welp, it's July now, so we've completed half of 2020. (You can insert your own adverb there; I'll go with "only.") A couple of things magically changed or got recorded at midnight, though. Among them: The Lake Michigan-Huron system finished its 6th consecutive month of record high water levels, with June 2020 levels a full meter over the long-term average. Illinois' minimum wage went up to $10 per hour, and Chicago's to $14. Both minima will increase by $1 per year until they reach $15. China has...

I rode the El yesterday for the first time since March 15th, because I had to take my car in for service. (It's 100% fine.) This divided up my day so I had to scramble in the afternoon to finish a work task, while all these news stories piled up: Josh Marshall unmasks the PPE debate. Matthew Sitman explains "why the pandemic is driving conservative intellectuals [sic] mad." Michigan's Attorney General called the president "a petulant child," called Lake Huron "a big lake," and called the Upper Peninsula...

Since January 2019, Chicago has had only two months with above-average sunshine, and in both cases we only got 10% more than average. This year we're ticking along about 9% below, with no month since July 2019 getting above 50% of possible sunshine. In other news: Former White House Butler Roosevelt Jerman, who served from 1957 to 2012, died of Covid-19 at age 91. One wonders, if the current White House had acted more propitiously, would Jerman have lived longer? Researchers suggest yes, if we'd locked...

Illinois has had a stay-at-home order in effect for over seven weeks now, though last week the state and county opened up forest trails and other outdoor activities that allow for proper distancing and discourage people clumping together in groups. So today I drove up to the northern suburbs to the site of the largest Civilian Conservation Corps project undertaken during the agency's run from 1933 to 1940. It was good to get outside. Not my fastest-ever pace, but still respectable, and somehow I got...

A pool of warm air running all the way up the Rocky Mountains to Alaska has forced a blob of cold air down into the eastern United States. This has started driving temperatures down all throughout the northeast, with a forecast drop to 10°C below normal here in Chicago and possible snow as far south as Philadelphia. In May. Ah, well. We all feel like it's March 68th, anyway. And yes, this cold snap is a consequence of climate change.

Happy May Day! Or m'aidez? Hard to know for sure right now. The weather in Chicago is sunny and almost the right temperature, and I have had some remarkable productivity at work this week, so in that respect I'm pretty happy. But I woke up this morning to the news that Ravinia has cancelled its entire 2020 season, including a performance of Bernstein's White House Cantata that featured my group, the Apollo Chorus of Chicago. This is the first time Ravinia has done so since 1935. If only that were...

The number of new Covid-19 cases per day may have peaked in Illinois, but that still means we have new cases every day. We have over 10,000 infected in the state, with the doubling period now at 12 days (from 2 days back mid-March). This coincides with unpleasant news from around the world: Covid-19 has become the second-leading cause of death in the United States, accounting for 12,400 deaths per week, just behind heart disease which kills about 12,600. More than 5 million people filed for unemployment...

As we go into the fourth week of mandatory working from home, Chicago may have its warmest weather since October 1st, and I'm on course to finish a two-week sprint at work with a really boring deployment. So what's new and maddening in the world? The Trump Administration's chaotic response to the virus includes seizing states' protective equipment and giving it to private distributors, thus making states bid on stuff they've already obtained, sometimes for free. Citizens for Responsibility and Ethics...

The frozen continent hit its all-time-warmest temperature yesterday: Just days after the Earth saw its warmest January on record, Antarctica has broken its warmest temperature ever recorded. A reading of 18°C was taken Thursday at Esperanza Base along Antarctica’s Trinity Peninsula, making it the ordinarily frigid continent’s highest measured temperature in history. The Antarctic Peninsula, on which Thursday’s anomaly was recorded, is one of the fastest-warming regions in the world. In just the past 50...

I'm visiting one of my oldest friends in Durham, N.C. She is fostering Lexi, who had nine puppies on the 5th: So, it turns out that puppies under two weeks old (a) smell horrendous, no matter how often you change their bedding, and (b) don't do a lot. But in the 18 hours I've been here most of them have opened their eyes for the first time. And they are really cute. This morning we took a short hike at the Museum of Life and Science, which encourages John Cleese to visit: It helps that while Chicago...

Climate change has caused water levels in the Lake Michigan-Huron system to swell in only six years, creating havoc in communities that depend on them: In 2013, Lake Huron bottomed out, hitting its lowest mark in more than a century, as did Lake Michigan, which shares the same water levels, according to data from the U.S. Army Corps of Engineers and the National Oceanic and Atmospheric Administration. Around that time, the lake withdrew so far from the shore around Engle’s resort — then a collection of...

A new United Nations report projects that the world's average temperature will hit 3.9°C above pre-industrial levels in 80 years without massive, immediate cuts in greenhouse-gas emissions. The additional energy the atmosphere has absorbed in the 80 years has given us the perfect Thanksgiving weekend travel environment: Not one, not two, but three powerful storm systems will make travel difficult to near impossible at times both before and after Thursday’s holiday. A record-breaking “bomb cyclone”...

Last night, Chicago set an all-time record for the warmest low temperature in October: 23°C, which feels more like mid-July than early-October, following the high yesterday of 30°C. Not to fear, though. A cold front came through just after midnight, bringing the temperature down to 14°C by 8am. With drizzly rain. Gotta love Chicago.

October began today for some of the world, but here in Chicago the 29°C weather (at Midway and downtwon; it's 23°C at O'Hare) would be more appropriate for July. October should start tomorrow for us, according to forecasts. This week has a lot going on: rehearsal yesterday for Apollo's support of Chicago Opera Theater in their upcoming performances of Everest and Aleko; rehearsal tonight for our collaboration Saturday with the Champaign-Urbana Symphony of Carmina Burana; and, right, a full-time job....

A few good reads today: Bruce Schneier compares genetic engineering with software engineering, and its security implications. The Atlantic has goes deep into the Palace of Westminster, and its upcoming £3.5 bn renovation. NOAA's chief scientist publicly released a letter to staff discussing the "complex issue involving the President commenting on the path of [Hurricane Dorian]." Illinois has pulled back some regulations on distilleries, giving them an easier time competing with bars and restaurants....

Yesterday evening, I needed to wear earmuffs and gloves when walking Parker because of the 7°C weather. Yes, it's the middle of May, but we've had a really screwy spring this year. Today I don't need gloves. Our official temperature bloomed from 8°C to 26°C in the past six hours. Even close to the lake, where I live, it's already warmer outside than inside—and I had the heat on briefly this morning! Today the forecast looks hot and humid, before temperatures plunge again Sunday night. Then hot again...

The day after a 3-day, 3-flight weekend doesn't usually make it into the top-10 productive days of my life. Like today for instance. So here are some things I'm too lazy to write more about today: More evidence that living on the west side of a time zone causes sleep deprivation. Over the weekend, at 2pm on Saturday, Chicago set a record for the lowest humidity on record. A software developer and pilot looks at the relationship between the software and hardware of the Boeing 737-MAX. The grounding of...

Wherever a landmass had several kilometers of ice on top, it deformed. Glaciers covered much of North America only 10,000 years ago. Since they retreated (incidentally forming the Great Lakes and creating just about all the topography in Northern Illinois), the Earth's crust has popped back like a waterbed. Not quickly, however. But in the last century, Chicago has dropped about 10 cm while areas of Canada have popped up about the same amount: In the northern United States and Canada, areas that once...

A week ago at this hour, it was -17°C outside and we had 230 mm of snow on the ground. Then the Polar Vortex hit, followed quickly by the biggest warm-up in Chicago history: From 17:37 CST Tuesday the 29th until 23:51 Thursday the 31st, the temperature hung out below 0°F. But it had already started rising, from the near-record-low -30.6°C Wednesday morning until yesterday afternoon's near-record-high 10.6°C—a record-smashing total rise of Δ41°C. This was the view from my office Friday evening, when the...

The official temperature at O'Hare got down to -31°C before 7am. Here at IDTWHQ it's -28.4°C. We didn't hit the all-time record (-32.8C) set in 1985, but wait! We will likely hit the low-maximum temperature record today. WGN reports that temperatures under -29°C have occurred only 15 times since records began 54,020 days ago. And the Wiccan coven next door has just received a shipment of battery-heated, thermal-insulated sports bras. So, I'll be working from the IDTWHQ today. And tomorrow.

The forecast for Wednesday not only predicts the coldest day since 1996. Now meteorologists predict the coldest day ever recorded in Chicago: Temperatures are forecast to inch up to a daytime high of about -26°C on Wednesday—the first subzero [Fahrenheit] high temperature in five years and the coldest winter high ever recorded in Chicago—before dipping, again, to about -29°C overnight. The coldest daytime high in Chicago was -24°C on Christmas Eve 1983. For younger Chicagoans, the burst of Arctic air...

We've had some snow, and we've had some cold, but this week we will have both. A lot of both: TonightSnow, mainly after midnight. The snow could be heavy at times. Patchy blowing snow after 11pm. Temperature rising to around -3°C by 5am. Wind chill values as low as -19°C. Breezy, with a south southeast wind 15 to 25 km/h increasing to 30 to 40 km/h. Winds could gust as high as 50 km/h. Chance of precipitation is 100%. New snow accumulation of 80 to 120 mm possible. MondayDrizzle and snow, possibly mixed...

The New York City subway, with its passive air exchange system and tunnels too small for active ventilation or air conditioning, have gotten excessively hot this summer: On Thursday, temperatures inside at least one of the busiest stations reached 40°C—nearly 11°C warmer than the high in Central Park. The Regional Plan Association, an urban planning think tank for the greater metropolitan area, took a thermometer around the system’s 16 busiest stations, plus a few more for good measure, and shared the...

Temperatures in southern Portugal and Spain have reached 45°C as dust from the Sahara turns skies orange: In the latest phase of a summer of extreme weather that has brought blistering heat to Britain, drought to the Netherlands and deadly wildfires to Greece, the heatwave affecting parts of southern Europe has reached a new intensity this weekend. According to IPMA, the Portuguese weather agency, about a third of the country’s meteorological stations broke temperature records on Saturday. The highest...

Sediment under Lake Chichancanab on the Yucatan Peninsula has offered scientists a clearer view of what happened to the Mayan civilization: Scientists have several theories about why the collapse happened, including deforestation, overpopulation and extreme drought. New research, published in Science Thursday, focuses on the drought and suggests, for the first time, how extreme it was. [S]cientists found a 50 percent decrease in annual precipitation over more than 100 years, from 800 to 1,000 A.D. At...

I'll have an update to the semi-annual Chicago Sunrise Chart later this week, but otherwise not a lot to post about. Or, anyway, that I want to post about. At least the weather cooled off. We finished June hot and sticky but yesterday a cold front brought delightful summer weather to the city. It's predicted to last about another four minutes.

It's gloomy, foggy, rainy, and not all that warm today, so I'm doing very little of value. I'll probably do something of value tomorrow, though.

Illinois State Climatologist Jim Angel has a report: Based on preliminary data, the statewide average temperature for May in Illinois was 21.4°C, 4.4°C above normal and the warmest May on record. The old record was 20.8°C set back in 1962. A brief examination of daily records indicates that Springfield, Champaign, Quincy, and Carbondale all had daily mean temperatures at or above normal for each day of the month. On the other hand, Chicago, Rockford, and Peoria had a few dips into the below-normal...

Writing in the New York Times, University of Washington professor Cecilia Bitz sounds a four-klaxon alarm about the rapidly-warming Arctic: In late February, a large portion of the Arctic Ocean near the North Pole experienced an alarming string of extremely warm winter days, with the surface temperature exceeding 25 degrees Fahrenheit above normal. These conditions capped nearly three months of unusually warm weather in a region that has seen temperatures rising over the past century as greenhouse gas...

Which explains why it's just above freezing and pissing with rain. Yesterday the temperature dropped from 15°C to 5°C in about 90 minutes as a cold front swept in from the north. Today we're living with the result. Oddly, though, the current temperature (3°C) isn't that far from the normal March 1st temperature (4°C). So perhaps we shouldn't complain. But that taste of spring we got earlier this week made us all anxious for the real thing. It's Chicago. The weather will change in a day or two.

While we hope it will not repeat early February 2011, we expect to get up to 300 mm of snow overnight and into tomorrow here in Chicago: The Chicago area is under a winter storm warning from Thursday evening through Friday night, with the National Weather Service warning that "travel will be very difficult to impossible at times, including during the morning commute." Much of the area should see 6 to 10 inches of snow between 6 p.m. Thursday and 9 p.m. Friday, though some areas to the north of the city...

Yesterday I spent almost the whole day cooking and eating, while outside the temperature barely got above -10°C. So despite averaging better than 15,000 steps for the entire week preceding, I only managed 7,292 steps yesterday, my 3rd poorest showing of 2017. The problem is, when I'm working from home, I get most of my steps by taking Parker on long walks. Below about -10°C, even his two thick fur coats aren't enough to keep him warm for more than 10-15 minutes, tops. And below -18°C, forget it; even...

Too much to read today, especially during an hours-long download from our trips over the past two weeks. So I'll come back to these: The CIA recently fired Lulu, a black Lab, because she didn't want to sniff for bombs after all. But more seriously: Josh Marshall calls out White House Chief of Staff for making the detestable argument that an attack on the President is an attack on the troops. Alex Shepard at New Republic just shakes his head sadly. London is running adverts aimed at cleaning up its air...

Following up on last week, Ask the Pilot weighs in on exactly why the heat in Phoenix is grounding airplanes: Extreme heat affects planes in a few different ways. First, there are aerodynamic repercussions. Hotter air is less dense than cooler air, so a wing produces less lift. This is compounded by reduced engine output. Jet engines don’t like low-density air either, and don’t perform as well in hot weather. Together, this means higher takeoff and landing speeds — which, in turn, increases the amount...

Phoenix hit a record high temperature yesterday of 48°C, and it's already that hot again today. And right now, it's 50°C in Needles, Calif. In fact, it's too hot for airplanes to take off: As the Capital Weather Gang reported, the Southwest is experiencing its worst heat wave in decades. Excessive heat warnings have been in effect from Arizona to California and will be for the remainder of the week. And it was so hot that dozens of flights have been canceled this week at Phoenix Sky Harbor International...

A little busy today, so I'm putting these down for later consumption: Via the Illinois State Climatologist, NOAA has released its state climate summaries for the country. Brian Beutler worries about President Trump's ego driving life-or-death decisions. Hollywood Reporter has some new photos from Game of Thrones' upcoming 7th season. Space junk and thousands of tiny, new satellites might make low orbit inaccessible in 50 years. Why are Germany's nude beaches (and parks and lawns and basically every part...

The snow continues to fall: The Chicago area remained under a lake-effect snow warning as the Tuesday morning rush slowed to an icy crawl on expressways and some Metra train lines. The warning covers Cook, Lake and DuPage counties until 4 p.m.  In Lake County, Ind., the warning has been extended to 1 a.m. Wednesday. The dense snow was being carried by winds from the north to northeast over Lake Michigan.  The snow bands were expected to slowly shift into northwest Indiana later in the morning and...

It's official: for the first time in recorded history, Chicago had no snow on the ground during the last two months of meterological winter (January and February): Because the snow measurement is taken at 6 a.m. at O'Hare International Airport, small amounts of snow that may have fallen later in the day and melted were not recorded, said Amy Seeley, meteorologist with the National Weather Service. This occurred Feb. 25 when there was a trace of snow and Jan. 30 when there was 2 mm. The weather service...

The windows at Inner Drive Technology World Headquarters are all open—yes, on February 17th—because it's 18°C outside. This is the normal high temperature for May 1st. Parker's having a bath, too, so the weather is great for him to walk home from the doggy daycare place.

January 3rd is one of my favorite days of the year in astronomy, because it's the day that the northern hemisphere has its latest sunrise of the winter. This morning in Chicago, the sun rose at 7:19 (though it rose behind a thick rainy overcast), just a few seconds later than it rose yesterday. But tomorrow it will rise just a few seconds earlier, then a few more, until by the end of January it'll rise more than a minute earlier each day. Meanwhile, thanks to the eccentricity of our orbit around the...

Here's the semi-annual Chicago sunrise chart. (You can get one for your own location at http://www.wx-now.com/Sunrise/SunriseChart.aspx.)

Tonight I've gotten invited to hear Lin-Manuel Miranda speak at the Lyric Opera of Chicago, and after that, a masquerade. Then tomorrow is Chicago Gourmet. Then Sunday I'll either plotz or walk 30 kilometers. (Though in truth I'll probably be fine as my cold, tapering though it is, makes me not want to indulge too much.) Meanwhile, here are some articles that I may read in the next few hours: This month has been really hot and rainy in Illinois. Bleah. One more thing Trump is wrong about: Stop and...

So...I hate to admit this, but I'm going to US Cellular Field tonight, because my trivia team won a bunch of Sox tickets. This will make me 0-for-3 on paying to get into the place, which I like. And tonight, in a very literal way, the park will go to the dogs: The White Sox will receive an attendance boost from some canine fans Tuesday when the team hosts its annual “Bark at the Park” event, and they hope it’s enough to set a new Guinness World Record. The Sox are attempting to set a record for the most...

Day two of Certified Scrum Master training starts in just a few minutes (more on that later), so I've queued up a bunch of articles to read this weekend: The climate prediction center forecasts a warm, dry fall for Illinois followed by a normal winter. Reactions to Trump dumping Russian stooge Paul Manfort in favor of right-wing nutjob Steve Bannon are pretty consistent: here's Fallows and Bloomberg, for starters, plus analysis from the Times and Marshall on how Trump's support is declining even among...

The National Climate Prediction Center has released its outlooks for the next few months, and they look mixed for Chicago: For the summer months of June, July, and August, the outlook for Illinois is [equal chances] for rainfall and an increased chance of being above-normal on temperatures. It is a rare combination in Illinois to have a warmer than normal summer without being drier than normal as well. For September, October, November, southern Illinois has an increased chance of being drier than...

With two performances and two rehearsals over the weekend, I didn't have any time to post. I also didn't have as much time as I wanted to walk, though I did manage 20,249 steps for the weekend. (That was a little disappointing, especially because yesterday's weather was perfect for being outside.) Meanwhile, the chorus have finally put up videos of our April fundraiser. So, yeah, we did this: I'll leave finding videos of me holding a puppet as an exercise for the reader.

Illinois State Climatologist Jim Angel lists all the records Illinois set last year: The warmest December on record: 4.8°C, 5.9°C above average. The second warmest September – December on record: 11.8°C, 2.7°C above average. The 8th coldest February on record: -7.0°C, 6.4°C below average. Annual: 11.6°C, 0.2°C above average (not ranked, but of interest) Precipitation: The second wettest December on record 170.1 mm, 101.8 mm above average. The wettest November-December on record: 312.4 mm, 156.2 mm above...

Stuff to read (or watch): Yesterday, Labour shadow foreign secretary Hilary Bent made the case to the House of Commons for bombing Syria. Republican leaders still don't believe (or pretend not to believe) that climate change is happening... ...even while glacier data shows conclusively that it is. Waukegan, Ill., may open a Ray Bradbury museum in the library building he frequented as a child. Chi-Raq is probably a really good film. Back to the mines.

Sunday morning, after Saturday's snowstorm: Last night, making mini turkey pot pies for tomorrow: That's all from scratch. Inside a rosemary-sage crust, from the bottom we've got turkey, pinot noir-reduction gravy, stuffing with organic Italian sausage, and cranberry sauce made with cranberries, orange, honey, and a secret ingredient that makes them amazing. I think I'm going to gain three kilos this weekend.

I hope Chicago has decent weather for the full moon 11 days from now: It's coming Sept. 27 at 9:47 p.m. CDT. For starters, it is what some astronomy enthusiasts call a "super" moon because it will occur when the moon is close to perigee, its nearest point to Earth in its elliptical orbit. The moon reaches perigee Sept. 28, and it will be just more than 222,000 miles away at the time of the full moon. That is about 31,000 miles closer than lunar apogee, the moon's farthest point in its orbit. The moon...

Another consequence to a four-hour drive and lots of household chores yesterday was my first Fitbit goal miss since June 6th. I only got 8,000 steps yesterday, after exceeding 10,000 steps for the last 71 days straight. It was also the fewest steps I've gotten since May 29th. I traveled on all three days, which explains the correlation: lots of sitting in vehicles and not a lot of opportunity to move. It didn't help that the temperature has hovered around 32°C for the past few days, forecast to cool off...

Jeff Skilling at the Chicago Tribune updates us on the equatorial Pacific: The current El Nino comes together against a backdrop of warming oceans and oceans which are growing more acidic as they observe mass quantities of CO2 produced through the burning of fossil fuels and the release of CO2 into the atmosphere this produces. More on the rate at which the planet’s oceans are warming here. It’s estimated that the warming which has taken place in the world’s oceans since 1990 is the equivalent of having...

The weather's perfect, there are holiday parties, and possibly some hiking. So not much blogging this weekend. There was also a small Ribfest nearby, but aside from Rod Tuffcurls & the Bench Presses, kind of disappointing (especially the vendor who ran out of ribs). More later as circumstances warrant.

As feared, last month was the wettest June on record in Illinois, and the second-wettest month of all time: The statewide average precipitation for June 2015 in Illinois was 242.1 mm, based on available data through June 30. That is 135.4 mm above the average June precipitation, and the wettest June on record for Illinois. In addition to being the wettest June on record, it is the second wettest month on record for Illinois. Only September 1926 was wetter at 244.4 mm – just 2.3 mm higher. Meanwhile, in...

The unpacking continues, but I still have too many boxes cluttering up the place: It is, however, a gorgeous day, and my office window is open to this: My goals are (a) do my work instead of going for a long walk in the perfect weather, and (b) finish unpacking my living room tonight. I may succeed in both. Updates as conditions warrant.

Yesterday was 17°C below normal in Chicago, the 8th consecutive day of frigid temperatures here, including a new record low maximum yesterday of -16°C. And while 19 states had record lows yesterday, western states are baking: "Winter seems to have completely forgotten about us out here," Kathie Dello, deputy director of the Oregon Climate Service at Oregon State University, told the Associated Press. "If we could find a way of sending [the Northeast] snow out here, we'd really, really appreciate that."...

...and we had record cold this morning: Around daybreak, the temperature at O'Hare International Airport dropped to -22°C, beating the record of -21°C for this date set in 1936. Winds from the northwest at 15-25 km/h made it feel like -30 to -35°C, and a wind chill advisory remained in effect until noon. The coldest places this morning included -25°C in Aurora, Harvard and Island Lake, -24.4°C in DeKalb and -23.9°C in Mundelein, Union, Waukegan and West Chicago. Wind chills ranged from -33°C in Fox Lake...

Local Manchester, N.H., television station WMUR mentioned my weather application on the news last night: There was only one place in the world colder than Mount Washington this morning: the south pole. The weather website wx now.com says the summit's temperature of 35 degrees below zero early this morning was the second coldest reported temperature on the entire planet. I can't wait to see the Google analytics.

As of Saturday, Chicago set a new record in gloominess by having no sunshine at all for 17 days in December: Low pressure passed to our north and a cold front swept through our area from the west Saturday. Winter Weather Advisories for 50 to 200 mm of snow were in place from northeast Nebraska through northern Iowa and southern Minnesota into northern Wisconsin and Upper Michigan, while cloudy skies and widely scattered light rain showers prevailed across the Chicago area. But those clouds cut off the...

...I stopped here one more time this morning: At the moment Chicago's weather isn't too bad. At the moment. But it's still nothing like this. By the way, I've actually reduced the saturation in this photo a bit. The sun was directly behind me and relatively low on the horizon, so the colors in this shot are very close to what I saw.

Yesterday, the majority of weather models forecast a major winter storm over Chicago that was going to snarl traffic, ground airplanes, and make life a living hell for several friends of mine. One of the models had a slightly different prediction, however. Looks like the minority opinion was right: The northbound storm driving Chicago’s Christmas Eve 2014 rainfall is going to have a hard time producing the kind of cooling which would support big snow accumulations. It’s been clear from the range of...

Yesterday, Chicago had its third earliest snowfall in recorded history. The previous record was 22 September 1995. Yesterday morning's low of 2°C just barely missed the record—0°C in 1989—and felt pretty damn cold for October when Parker and I went out first thing in the morning. The forecast calls for seasonal temperatures Tuesday and Wednesday, but crappy rainy cold November-like weather tomorrow and Thursday. Wonderful. Because what Chicago needs in October is November weather. On the other hand, we...

We had spectacular weather across the region Saturday and yesterday. For our hike Saturday we had partly-cloudy skies, low humidity, and 14°C—nearly perfect. Here's Parker at the top of the trail, refusing to look at the camera: Then, yesterday, I had my final Apollo audition up at Millar Chapel in Evanston. Again, perfect weather: It's a little cloudy today, but otherwise cool and October-like. As far as I'm concerned, it can stay October-like for the next six months. Walking is good for you. Also, can...

Wow, last night's rain was officially epic: The rate at which rain fell across the Midwest Monday was extraordinary in a number of locations. Highland, Park’s 98 mm fell between 6 and 11:59 p.m. In just a fraction of that period, Midway Airport logged 20 mm. It fell in just 7 minutes! Lake In the Hills , IL received 66 mm in just 2 hours. But rainfall rates west in Iowa were even more dramatic. Williamstown received 133 mm in the day’s 3 waves of rainfall while 114 mm of Muscatine, Iowa’s 207 mm of rain...

Last night the temperature here got down to 5°C, which feels more like early March than mid-May. Meanwhile, in San Francisco, yesterday got up to 33°C, which to them feels like the pit of hell. In fact, even in the hottest part of the year (early October), San Francisco rarely gets that warm. The Tribune explains: The North American jet stream pattern, a key driver of the country’s weather, has taken on the same incredibly “wavy”—or, as meteorologists say —“meridional”—configuration which has so often...

It looks like we're going to go 71 days with snow on the ground before it all melts. But a couple of subtle yet telling things have happened since I last griped. First, the temperature has gone up since sunset, as forecast. It hasn't gone up a lot, but the influx of warm air from the Gulf of Mexico will continue through tomorrow, to the detriment of all the snowdrifts in Chicago. It's hard to get your mind around how much heat the atmosphere moves around. A human being can generate about 6-8 megajoules...

The Great Lakes have more ice cover than at any point in the last 20 years. Here's the view on the flight in last Monday morning: If you don't mind a 150 MB download, NASA took a photo of the Great Lakes (and, incidentially, me) at almost that exact moment. The ice today (also 150 MB) looks about the same.

Yesterday, Chicago Midway Airport recorded a high temperature of 1.1°C, the first time it has seen a temperature above freezing in 15 days. Unfortunately for our weather records, O'Hare is our official station, and it only got to 0°C yesterday. So officially we still have not had a day above freezing since January 30th, with a forecast for continued below-freezing weather through Monday at least. Plus, we've had measurable snow on the ground for 47 days now, and we're all frankly sick of it. That's why...

Wow. Getting off the plane in New York last night, then taking the bus into Manhattan during a gentle snowfall (during rush hour, on the Van Wyck and Grand Central Parkway), reminded me why I went to St. Maarten for the weekend. Getting home to this made me ask why I didn't stay longer: Today was the 20th day this winter that temperatures have dipped below -18°C at O’Hare. Tomorrow should be the 21st. That is triple the average of 7 days per winter. The record number of sub-zero days for a winter was 25...

I'm sitting in the only spot in my hotel that has free WiFi, with a dozen or so other people doing the same thing. Plus, it's possible this is the slowest WiFi in the world (I'm getting 150 kbps). These things make it easy to get out of the building, into island air that's currently 27°C. I know, I said to people I wouldn't use the internet, but I actually needed a map and some local info that the giant book of wristwatch advertisements guidebook didn't actually tell me. Plus, I forgot three somewhat...

While the eastern United States continue to freeze in between snowfalls, Alaska is experiencing an astounding heat wave: To give people an idea how freaky an event this was for the 49th State, NASA has put together a visualization of phenomenal temperatures from January 23 to the 30th. Based on satellite readings, the map shows warm-weather abnormalities spreading in red all across the region. Areas of white were about average, meanwhile, and blue spots show cooler-than-normal temps: One of the most...

The temperature tumble that began yesterday evening seems to have leveled off. From 6pm yesterday to 6am today we had the steepest decline (17°C) with an abrupt plateau at sunrise this morning, now holding at -19°C. I might have to leave the house this afternoon to pick up a couple of necessities, like cream. (Yes, it's worth braving the Arctic to get cream for my coffee tomorrow.) Otherwise, my office is closed for two days, and Parker's at day camp, so until his 9pm walk tonight I really have no...

Just 120 hours ago, a polar vortex wandered into the center of North America and froze us solid. Less than an hour ago, at 8:39am CST, the official temperature at O'Hare hit 0°C—27°C warmer than 9am Monday morning. It's also the first time the temperature has gotten up to freezing since December 29th. I've lived in Chicago for a long time, so I can say this graph is extraordinary (data from my demo at Weather Now: Of course, with 250 mm of heavy, wet snow on the ground, rain in the forecast, and...

The temperature outside has gone up a whopping 0.9°C (to the tropical -23.6°C) since this morning. At O'Hare, it looks like the temperature bottomed out around 8am: Let's hope it continues to rise. I'm really curious what this graph will look like in three days.

Yes. And snowy: Snowfall’s been quite relentless here. Flurries (or more) have fluttered to earth 8 of the past 9 days. And, with just under 250 mm on the books to date, the 2013-14 season has been accumulating snow at nearly twice the normal pace and ranks 33rd snowiest of the past 128 years. That places it among the top quarter of all Chicago snow seasons since records began here in 1884-85. There’s been only one day with a temperature even briefly above freezing in the past 12. An eight day string of...

My company's holiday party happens tonight, preceded by a stop at a client's party, so it makes a lot of logistical sense just to hang out at IDTWHQ and bang away on work. But there's another practical reason: With the opening 11 days of December 2013 running 9.2°C below a year ago, the Chicago area moves into an 8th consecutive day in this early Deep Freeze. The past 7 days have averaged -8.7°C, a jarring 7.8°C below normal—-cold enough to have ranked 8th coldest on record here and the coldest such...

In Chicago, we take these things seriously: Not since October 2011 have four consecutive 100% sunny days occurred in Chicago. Through Thursday, three days of unlimited sun have entered the record books. Our forecast of another day of abundant sun Friday could challenge that record. To date, September’s generated 69% of its possible sun—more than the 64% which is normal! Of course, in a state with a majority of its gross domestic product coming from agriculture, there's a downside: The US Drought Monitor...

Parker and I have walked about 90 minutes today, and we'll probably walk some more half an hour from now. It's 23°C and crystal clear, with a forecast for more of the same all weekend. I may not get anything done until Monday. Pity.

Chicago has experienced its first big heat wave of the year, with temperatures above 32°C every day this week. Yesterday, 46 of the lower 48 states reported temperatures in that range, with only North Dakota and Minnesota spared. A friend who lives in San Francisco posted this with the caption, "Summer hits the Bay Area:" It cooled down last night, so it's now just about 26°C...here. Only I'm going to New York in a few hours, where today will not only get to 35°C, but will have violent thunderstorms and...

The twister—as much as a 4200-meter-wide monster can twist—that hit Oklahoma last week broke all kinds of records: In the rare category of EF5 tornadoes, the one on Friday in the El Reno area was “super rare,” a National Weather Service meteorologist said Tuesday. The Weather Service updated its estimate Tuesday of the tornado that struck El Reno Friday, determining it was an EF5, the strongest classification for a twister. It was a record 4.2 km wide and tracked across 26 km. During Friday's storm, the...

National Public Radio has created an interactive map that uses Google Maps and new satellite images Google obtained yesterday to show 10-meter images of the Oklahoma tornado's destruction: This may be the best, most timely use of geographic information in a news presentation I've ever seen. The images are stunning. I can only imagine what life must be like in Moore right now—and with the NPR app, it's a lot easier to understand.

Parker and I took our first walk in pouring rain, but things seem to have cleared up. The Tribune expects OK weather for the 1:20 start: Despite a wet, gloomy and cool start to the day, conditions should improve dramatically this afternoon in time for the Cubs opener. Temperatures around 7°C this morning will rebound into the teens later today with the passage of a warm front. The Cubs, now 2-4 for the season and having already replaced their benighted reliever Carlos Marmol, would at least not lose a...

Chicago has finally gotten up to 21°C for the first time since December 1st. My screens are back in, my dog got some good walks, and my apartment is fresher. I just hope it's like this on Monday.

As I look out my window and see snow falling, I can't help thinking back to last March, in which we'd already had the third record-warm day in a row (27.8°C) on our way to the warmest spring in Chicago history. This March, not so much: So far, March has been both colder than average across all of Illinois and wetter than average across western and northern Illinois. The statewide temperature for March 1-14 was 0.2°C degrees, 3.0°C below average. That stands in stark contrast to last March when the...

Looking at Poynter's roundup of storm front pages, I'm struck that the New York Post called the storm "Nemo." Two things: 1. Winter storm names are an invention of The Weather Channel, a move the National Weather Service has explicitly repudiated. 2. Nemo is Latin for "nobody." So the Post's headline yesterday, "Nemo Bites"—i.e., "no one bites"—just reinforces the stupidity.. Anyway, I know my friends out east have unprecedented disastrous a bit of snow to survive endure inconvenience them today. Enjoy...

Why? Because it's too cold for clouds. Actually, this is one of those correlation-causation issues: cold days like today (it's -15°C right now) are usually clear and sunny because both conditions result from a high-pressure system floating over the area. Still, it's pretty cold: A February hasn’t opened this cold here in the 17 years since 1996. The combination of bitterly cold temperatures, hovering at daybreak Friday near or below zero [Fahrenheit] in many corners of the metro area, plus the biting...

Chicago's normal high temperature for April 17th is 16°C, which by strange coincidence is the new record high for January 29th: The warm front associated with the strong low pressure system passed through the Chicago area between 2 and 3AM on it’s way north and at 6AM is oriented east-west along the Illinois-Wisconsin state line. South of the front south to southwest winds 24 to 45 km/h and temperatures in the upper 10s°C prevail – Wheeling actually reported 15.6°C at 6AM. North of the front through...

Nearly 65% of the lower 48 United States has snow cover, including parts of every state except for the seven between Louisiana and South Carolina. Chicago, for reasons not well understood, has just a trace on the ground and has gone 314 days without 25 mm of snow, 4 days short of the record set in 1940. Since we have no significant snow in the forecast, it looks like we'll break that record too. Other records threatened: number of days without 25 mm total snowfall accumulation, 312 (record is 313)...

No, I don't mean "will we have to endure another six weeks of an election." I mean that Chicago today hit 17°C, not a record (22°C in 1982), but also more normal for mid-October than for the second day of meteorological winter. Tomorrow may be warmer. The Climate Prediction Center forecasts a warm December followed by more normal temperatures through March, so we might get a good Chicago winter anyway. Remember, though, that warm winters lead to warm summers (though not necessarily the reverse), so I...

The temperature in Chicago dropped 13°C in six hours yesterday, taking us from summer to autumn between lunch and dinner: One minute it was summer, with the Chicago area basking in the warmest temperatures of the past 22 days---the next, howling northwest winds were delivering an autumn-level chill. Readings surged to 27°C at Midway and the Lakefront by mid afternoon but were soon on the run with the arrival of gusty showers—a few with lightning and thunder. These initiated the impressive temperature...

The National Hurricane Center predicts that Tropical Storm Isaac, currently smashing through the windward islands, may strike Tampa during the GOP convention: Of course, five days out the forecast has tremendous uncertainty. The storm could change course or dissipate before hitting Florida, for example. But Tampa Mayor Bob Buckhorn, speaking about next week's GOP convention, is absolutely willing to call it off if they need to evacuate Tampa: So, my question is, now that the religious right has all but...

Chicago's average temperature this July will probably wind up at 27.2°C, making it the third-warmest in history behind 27.3°C 1921 and 27.4°C 1955. (Normal is 23.3°C.) Along with the near-record heat we've had more 32°C days so far than ever before. And it's not over: Never before, over the term of Chicago's 142 year observational record, have so many 90s accumulated at such an early date. July alone produced 18 days at or above 90---far beyond the seven considered normal, yet just shy of the 19 days of...

Yes, I just said I was taking Parker out for a walk, but I cut it short after five minutes. Here's why: Just as we got back home the gust front hit. Trees are now moving in ways that trees probably shouldn't. This should be a lot of fun to watch. ...but Parker is sulking. Tant pis, mon bête noir. Update, 1:25 pm: Huh. The storm just missed us, though reports have come in of 145 km/h gusts in Elmhust and Lombard, which "looks like a war zone" according to the Tribune.

A few months ago, when Chicago finished its 10th warmest winter (followed by its warmest spring ever), I predicted a warm summer. Actually, the state climatologist predicted a warm summer, and I repeated this prediction. Regardless, the mechanics are simple. Warm winters and springs keep Lake Michigan warm, which means come summer the lake can't absorb as much heat on hot days. This means, all things equal, a warm spring leads to a warm summer. (Oddly, though, warm summers have no effect on winter...

Happy Spring. The equinox happened less than 11 hours ago, which usually means Chicago has another six weeks of cold and damp weather. Not this time. Trees have buds and flowers, insects have started buzzing around, and as of about an hour ago, we've broken (or tied) our seventh consecutive heat record. This, by the way, is also a record (greatest number of temperature records broken consecutively), breaking the record set...yesterday. Here are the temperature records we've set so far this month: Date...

While Chicago finished its ninth-warmest (meteorological) winter in history on February 29th, Illinois as a whole finished its third warmest: This year the average winter temperature was 1.2°C, 2.9°C above normal, and the third warmest winter on record. Here are the top four warmest winters. As you can see, we had a two-way tie for second place. First place, the winter of 1931-32 at 2.8°C; Second place, a tie between 1997-98 and 2001-02 at 1.4°C; Third place, this winter at 1.2°C. Not only was it warm...

The judge responsible for the case against the time zone database filed back in September issued an order yesterday demanding that the plaintiffs actually pursue the case. Under the Federal rules of civil procedure, the plaintiffs now have 21 days to show they've served the defendants, or the case will be dismissed. I'm asking my attorney friends how common this kind of negligence is.

The Illinois State Climatologist is wondering if 2011-12 qualifies: The folks at the Chicago NWS office raised the following question. I would add to this that last winter Chicago O’Hare reported 1,470 mm of snow and 67 days with an inch or more of snow on the ground. This winter, through February 13, O’Hare reported 391 mm of snow and only 10 days with an inch or more of snow on the ground. Plus, 78% of the days from December 1st until now have been above average, with more than half of those days...

Via Sullivan, a snippet of conversation between Bob Dole and Newt Gingrich in the 1990s: "Why do people take such an instant dislike to me?" asked a perplexed Gingrich, to whom Dole bluntly explained: "Because it saves them time." In unrelated news, Parker and I are about to walk around in abnormally warm, sunny weather on what is statistically the coldest day of the year in Chicago. This is the warmest winter in 78 years, with the fewest sub-freezing maximum temperatures in 40 years. (Today was above...

Not just here, where we're looking forward to 10°C on New Year's Eve to complete a streak of 21 days above normal temperatures,, but also Northern Europe: Britons getting ready to ring in 2012 can expect highs of up to 15°C after a year of unusually mild weather. Forecasters said the past 12 months have been the second warmest for the UK after 2006, in which the average temperature reached 9.73°C. The average for 2011 was just a shade lower at 9.62°C. It comes after the warmest April and spring on...

Finally. In Chicago, anyway. The farther north you go, the more likely your latest sunset is...earlier. I explained why this happens December 8th a few years ago. And yet, I feel the need to comment on it yet again...

To better understand the facts behind Astrolabe’s stupid trolling quixotic lawsuit against the guys who coordinated the worldwide time-zone database (tzinfo), I bought copies of the Shanks Amercian and International atlases that Astrolabe claims to own. (I went through the secondary market, so I didn’t actually give Astrolabe any money.) First, an update. According to Thomas Eubanks of the IETF, the Electronic Frontier Foundation has taken over Arthur Olson’s legal defense. Mazel tov. I expect to see a...

This morning The Daily Parker received a press release from Gary Christen, responding to my analyses of their lawsuit against the guys who maintain the Posix time zone database (here, here, and here). Unfortunately for Christen, Astrolabe's response fails to rebut my central assertions. I said, essentially, they have failed to state a claim upon which relief can be granted by a Federal court (or, as one of my colleagues who actually practices law suggested, their complaint is actionable in itself)....

I'm David Braverman, this is my blog, and Parker is my 5-year-old mutt. I last updated this About... page in February, but some things have changed. In the interest of enlightened laziness I'm starting with the most powerful keystroke combination in the universe: Ctrl-C, Ctrl-V. Twice. Thus, the "point one" in the title. The Daily Parker is about: Parker, my dog, whom I adopted on 1 September 2006. Politics. I'm a moderate-lefty by international standards, which makes me a radical left-winger in today's...

We're still three weeks from meterological autumn and we've already had the wettest summer in 54 years and the second-wettest ever: The new rains are to fall in the midst of the Chicago area's wettest meteorological summer (the period which began June 1) in 54 years. A total of 420 mm has occurred to date which makes this the second wettest summer to date since the official observational record began here in 1871. That amount is nearly twice the 140 year average to date of 219 mm. And what do we have in...

Last night, after getting back from San Antonio, I opened the windows for the first time in nearly six weeks. We had, I believe, one of the hottest and stickiest Julys I've ever experienced. But yesterday when I got home the temperature was 23°C and dropping—finally cooler outside my air-conditioned apartment than inside it. Unfortunately for my colleagues down in Texas, it's no cooler there: DaySan AntonioChicago Sun Aug 738°C30°C Mon Aug 838°C27°C Tue Aug 9 39°C27°C Wed Aug 1039°C25°C Thu Aug...

Six months ago, at North Avenue Beach in Chicago: 2 February 2011, Canon 20D at ISO-100, 1/250 at f/11, 27mm, near here. I should have posted this photo a couple of days ago, when Chicago baked in near-40°C heat. Today's forecast calls for a mostly-pleasant 27°C under sunny skies. Go back and relive those few days last February when it gets hot again.

The Tribune today has this graph showing the extreme precipitation we've had this year:

So far in 2011, Chicago has not only experienced its wettest year ever, but we've almost reached our annual normal rainfall total: With the record (283 mm) July rains adding on to already above-normal precipitation prior to this month, Chicago's official total for 2011 has reached 858 mm - or 351 mm above normal at this point in the season. Chicago's official rain gage at the O'Hare International Airport observing site has now registered 93 percent of the normal annual 921 mm. Today, however, it's sunny...

Remember Tuesday, when we were only 13 mm away from having the wettest July in history? Thanks to a storm that dumped a squishy 259 mm of rain on nearby Dubuque, Iowa, Chicago's rainfall this month reached 248 mm, beating the old record of 243 mm set in 1889. Today's forecast calls for even bloody more rain: Showers and thunderstorms likely. Mostly cloudy, with a high near 32°C. Heat index values as high as 37°C. Southwest wind between 10 and 15 km/h. Chance of precipitation is 70%. New rainfall amounts...

Chicago is still experiencing weather more suited for the jungles of Cambodia: For a 12th consecutive day Wednesday, Chicago's lows have registered 22°C or higher—the first time that's happened in 12 years and only the fourth time such a long string of warm nighttime lows has been observed at Midway Airport since 1928. And it's still raining: another 111 mm fell on parts of the area this morning. A weekend in Canada starts to look very appealing...

Today has set the record as the wettest day in Chicago history, and (a) it's only 11am and (b) more rain is coming: Overnight rains that approached 178 mm over northern Cook County broke several impressive Chicago records. 176 mm of precipitation has been measured at O'Hare International Airport since Midnight making today, Chicago's wettest calandar day in modern weather history.

What happens when two air conditioners together draw more than 15 amps on a 15-amp circuit? This: (Click to see full-size.) The graph not only shows how quickly the place warmed up when the breaker tripped Wednesday evening, but also how slowly it cooled off once I closed the breaker. The initial cliff-like dive in temperature yesterday at 5:15pm happened because after turning the AC back on, I put a box fan next to the server rack and shut down two of the servers. You can see the temperature bumped up...

It appears the air conditioners back at IDTWHQ have failed, while I'm 1,700 km away: The chart starts at 7pm Chicago time Tuesday. The squiggle shows the backup air conditioner cycling on and off while it's in "energy saving" mode. That stops around 2pm yesterday, when, I imagine, the backup failed. Then, at 8:30pm last night, the main seems to have stopped. I'll be leaving San Antonio on an earlier flight. I just hope the A/C units have simply stopped, and that they'll start again when I turn them on....

Chicago has seen its hottest temperatures in years this week, with more coming today: Not since July 24, 2005 when O'Hare hit 39°C and a reading of 40°C occurred at Midway, has a triple-digit [Fahrenheit] reading occurred at the city's two observation sites. The entire 83 year observational record at Midway includes only 84 38°C or higher temperatures—and just 26 have occurred in the nearly half-century period since 1960. Good thing I'm not in Chicago this week. No, I'm in San Antonio, where the...

We'll know for sure in the next couple of hours when yet another line of storms comes through, but at the moment it looks like Chicago will break its May rainfall record today: [T]he approach of yet another vigorous weather system spells more storms - possibly severe - for waterlogged northeast Illinois. Only 10.4 mm of additional rain will catapult this May's rainfall, currently 182.6 mm, to 193 mm and the wettest May in Chicago weather history. Squish, squish, squish.

Today's gloomy morning makes it official: April 2011 was the gloomiest and wettest April in recorded Chicago history: Going into the last day of the month, this April has received only 32 percent of possible sunshine. Even with some morning sunshine, thickening cloudiness should cut out a significant amount of Saturday's sun - probably enough to hold this April's total sunshine number under what looks to be the old record low of 34 percent possible sunshine back in 1953. State climatologist Jim Angel...

Chicago got the name "windy city" from...well, no one really knows, but in fact Amarillo and New York top the league chart for average windiness: Notice Chicago isn't even in the top 10. Which isn't to say we're not blowhards; we're just not that windy. (Full-size image at The Chicago Tribune.)

I mentioned yesterday that having my car snowed in didn't bother me much. I do have to use it eventually, however. Today the temperature got above freezing, the warmest we expect it to be for the next week, at least. So, after 40 minutes with a shovel and a spade, I went from this: To this I will now shower. And nap.

First, a report out of Punxsutawney, Penn., that Punxsutawney Phil (the groundhog) did not see his shadow: Punxsutawney Phil emerged from a tree stump at dawn and, unusually, did not see his shadow, signaling that spring is just around the corner, according to tradition. "He found that there was no shadow," said Bill Deeley, president of a club that organizes Groundhog Day in the western Pennsylvania town of Punxsutawney. "So an early spring it will be." Ah, but there's a catch: "There is no question...

The weather we've worried about for a couple of days looks set to hit this afternoon: Four days of computer forecasts of this storm, including multiple runs off 7 models, are putting the developing system on a more northerly track while generating water equivalent precipitation of around 30 mm. To convert that to snow, calculations have to be made of how snowflakes are likely to develop in the storm given a snow/water ratio predicted to be 15 to 1 Tuesday evening. [This means 450 mm of snow. —ed.] As...

This winter Chicago has had below-average temperatures overall but nothing really cold. It's like a study in moderation, only unusual when you see the numbers rather than when you experience it: Just one day this season has produced a sub-minus-17 Celsius low temperature and only one day has failed to climb out of single digits. Since the start of the three month (December through February) meteorological winter period, 38 of the 59 days—64% of them—have generated below normal readings. It's a fact that...

The Chicago Tribune reported this morning that average Chicago temperatures have remained above normal month by month for the past nine in a row: The temperature trend to date may be among the most remarkable on record for the period here. November 2010 is to become the ninth consecutive month to close with a temperature which has averaged warmer than normal. That's a nearly unprecedented accomplishment. It means meteorological spring (March through May), meteorological summer (June through August) and...

My laptop screen saver showed this photo, so I decided, why not take a moment from writing a strategy paper and post it? Half Moon Bay, Calif., 24 December 2009.

Chicago hit 32°C yesterday for the first time since August 9th, and barely missed setting records: By the time Monday evening's rush hour was getting underway, 33°C highs had been logged at both Midway and O'Hare---18°C higher than the peak reading of 14°C a week earlier---a level 10°C above normal. Only 21 of the past 140 years have recorded a temperature of 33°C or higher this early in the warm season underscoring the rare nature of the hot spell. There hasn't been a warmer May temperature in Chicago...

A 7.2-magnitude earthquake rumbled through Baja California yesterday afternoon, killing one person directly and another indirectly: The quake struck about 6 miles below the earth's surface at 3:40 p.m. PT Sunday, about 110 miles east-southeast of Tijuana, according to the U.S. Geological Survey. After examining data, seismologists upgraded the size of Sunday's 25-second quake from a magnitude 6.9 to 7.2, according to Dr. Lucy Jones of Caltech. "This is the largest earthquake since the [7.3 magnitude]...

Forty nine states have snow on the ground right now thanks to a rash of snowstorms caused, in part, by human-induced climate change (.pdf, 1.8 MB). First, the situation on the ground: The extraordinary rash of snowstorms which have swept the U.S. in recent weeks, many generating record snowfall, have produced one of the country's most expansive snow packs in recent memory. National Weather Service researchers charged with monitoring the country's snow cover and its water content estimated Friday that...

Via several sites, a NASA photo of Great Britain from Thursday noontime: The U.K. doesn't usually get a snow cover at all, let alone one this thorough. The U.K. Met Office has an explanation: In most winters, and certainly those in the last 20 years or so, our winds normally come from the south-west. This means air travels over the relatively warm Atlantic and we get mild conditions in the UK. However, over the past three weeks the Atlantic air has been ‘blocked’ and cold air has been flowing down from...

Washington looks quite pretty from the air with all the snow on the ground: I'm confused. Yes, I see snow, and on the ground at DCA it seems to be about 30-35 cm deep, but in Chicago we'd find this annoying, not paralyzing. I wonder if Virginia still has the same number of snowplows as Chicago (which was true in 2003, the last time the area got "buried" like this). If so, maybe they want to examine some of the climate-change projections calling for more precipitation? Hmm. Diane and Parker are a few...

Yesterday I mentioned how helpful American Airlines was helping me avoid what promised to be an excruciating layover at O'Hare today. It turns out, Washington's weather is worse than even the most pessimistic forecasts: A snowstorm of historic proportions is burying a wide swath of the Mid-Atlantic under as much as 30 to 90 cm of snow as the weekend gets underway. The Washington D.C. area is to end up among the locations hardest hit with as much as 60 cm of snow a possibility -- the heaviest...

Remember how I mentioned packing for two out of the three climates I expected to encounter on this trip? I should note that I expected London to be warmer than Chicago. I also expected that I would only be outside in Chicago traveling from the O'Hare tram to my car, and my car to my apartment. I'm debating finding a wollens store and buying a good, heavy, Scottish sweater. Our next residency lets me do the same thing only moreso, when I get to go from Chicago to Delhi, India, at the end of January. At...

A quorum: After 8.3 hours of work, I finished my accounting final. I've no idea how well I did, but I'm already planning to ask the professor for a meeting when I'm next in Durham. We had our first freeze today, about three weeks earlier than usual. We missed the record low (-3°C, set in 1996), but after two weeks of below-normal temperatures, it was a fitting reminder of this year's El Niño. We also had the Chicago Marathon today, with a start temperature of 1°C. The cold start helped; Sammy Wanjiru...

A number of confusing changes occurred to the world while I slept: President Obama won the Nobel Peace Prize. I love the man; I voted for him; I gave lots of money[1] to two of his campaigns. I'm still confused. It might offend some of my fellow progressives to say, but possibly the prize means nothing more than "thank you for not being like the last guy, and keep up the good work." The President is, in fact, the second person who is not George W. Bush to win the Prize in the last four years. For...

Blowing off the last game of the season I bought tickets for did not come easily. I struggled with the decision for most of the afternoon. I needn't have: The temperature at Midway has flattened out at 13°C as a thunderstorm has started passing overhead. Oh, and après le déluge, the Cubs can resume in the top of the 4th with the last-place Pirates beating them 3-0. So, you know, I think I made the right choice.

Usually I hate July weather in Chicago. Not this year. We ended up with the coolest July in my lifetime (at Midway), and also one of the driest, making for an unusually pleasant month: Chicago's 69.4-degree average July temperature at O'Hare International Airport was the coolest of the past 17 years. But at Midway Airport, the month's 71-degree average temperature was the site's coolest in 42 years. Estimates based on the month's temperatures suggest the need for air conditioning was 30 percent below...

Chicago O'Hare just recorded a temperature of 4.4°C, the warmest it's been since December 30th. That is all.

It's a little thing, but it means our evenings won't seem as gloomy from now on: tonight's sunset in Chicago is the earliest of the year. Seriously. It has to do with the speed of the earth's orbit around the sun this time of year (it's faster, as we approach perihelion). In any event, tomorrow night the sun sets just a few seconds later than it does tonight, which just adds a little happiness this time of year.

I mentioned our weather today? Here's my polling place a little while ago: OK, time to stop blogging and get back to work. After I walk the dog again. (It's up to 22°C already. We don't get many days like this in Chicago, especially in November.)

The NHC hasn't wavered much on Ike's projected path: Houston is now officially under a hurricane watch. Even American Airlines thinks I'm not going to a Cubs game this weekend. But as my cousin said, "They can't lose if they can't play."

Living in a temperate climate means everything changes constantly. But there are rhythms. Things change fastest in late August and early March, for example: the sun set after 8pm from early May until just three weeks ago, but last night, the sun set at 7:30; in two and a half weeks it sets at 7; three weeks after that, at 6:30. So what prompted this nearly-inane observation? The insects. It's late evening and my windows are all open, so I can hear thousands of cicadas, grasshoppers, crickets—yes, even...

There's a write-up of last night's storms in the Trib: Clean-up efforts were under way Tuesday morning after a line of severe thunderstorms moved through the Chicago area Monday night, downing trees and power lines, starting fires, peeling off roofs, briefly closing down both Chicago airports and ending a Cubs game after two rain delays. As of 6:30 a.m. Tuesday, crews from the Chicago Department of Streets and Sanitation responded to reports of 1,104 damaged trees, 132 malfunctioning traffic signals, 55...

...but only because I got to watch it from inside my apartment. A major squall drove through Chicago this evening with 90 km/h winds (including two small tornadoes) and dime-size hail reported. My neighbors across the street have lost power, too. We didn't, but the Inner Drive Technology International Data Center battery backups complained loudly through the worst of the storm. It's gone now, which makes Parker happy for two reasons: he didn't enjoy the storm itself, and he really, really wanted to go...

For those of you who missed it last night, we had a total lunar eclipse, which the cold, clear weather in Chicago let us see perfectly:

The City of Evanston, my birthplace, bastion of good government, where I have lived for just over three years, has run out of road salt: [Evanston Public Works chief] David Jennings says that on Wednesday "our salt supplier notified us that they could not honor the balance of our current order, about 1,100 tons, due to difficulties in getting their supply of salt to the distribution point that serves us." Jennings says city crews have stopped salting residential streets, but are continuing to plow....

No sooner had our first snowfall melted when we started to get our second one: On the walk back from Inner Drive Technology World Headquarters he forgot his leash discipline a little, as when he nearly yanked my arm out of its socket when he saw a rabbit bounding through the snow. He was just so excited to see snow he couldn't contain himself.

Newsweek just published an article laying out how oil, gas, and other similar industries have bamboozled the American public for close to 20 years about climate change: Since the late 1980s, this well-coordinated, well-funded campaign by contrarian scientists, free-market think tanks and industry has created a paralyzing fog of doubt around climate change. Through advertisements, op-eds, lobbying and media attention, greenhouse doubters (they hate being called deniers) argued first that the world is not...

I admit that on occasion I've bought bottled water, for example on long road-trips. But I've also found it amusing that Evian backwards spells...well, you can figure it out. The Economist this week explains why, exactly, buying bottled water shows consumers are daft: The success of bottled water is in many ways one of capitalism’s greatest mysteries. Studies show consistently that tap water is purer than many bottled waters—not including those that contain only tap water, which by some estimates is 40%...

The June Solstice happens in 15 minutes, at 1:06pm CDT. Happy Summer! (Or, you know, winter, for the one-third of the world who live in the Southern Hemisphere.)

Four years. We weren't even in World War II for this long. I can't add anything really profound to the debate, but I will repeat something Garry Trudeau had on today's Doonesbury Daily Dose: "America has been conducting an experiment for the past six years, trying to validate the proposition that it really doesn't make any difference who you elect president. Now we know the result of that experiment."—Gen. Tony McPeak (retired), member of the Joint Chiefs of Staff during the Gulf War I would also like...

One of the side-effects of obedience training I didn't know ahead of time is that Parker is now crate-trained. Since he's also more than double the size he was when I first met him, the crate I had for him was a little tight. So I bought him a new crate, with more than double the footprint of his old one, and with a lot more light and air. Enough light and air, in fact, that I can point the ParkerCam at him when he's in it: Check for Parker during the day. If I remember to bring the camera to my office...

The clouds broke this evening just long enough for me to see the eclipse. As they say in Boston: wicked cool.

The eclipse will be total from 4:44 pm CT to 5:58 pm, so when the moon rises over Chicago at 5:39 pm it will appear a deep red. (If it appears at all, of course; the weather will likely be cloudy.) Observers on the East Coast will have a better view; Europeans will get to see the whole thing.

...and I don't mean on the locker-room floor. Just now NPR's Weekend Edition reported on a gym in Hong Kong that uses the kinetic energy from people walking on treadmills and using exercise bikes to power its lights. Neat.

At least one of my friends (ND-D) would be proud of me: as of tonight, all 21 of the lightbulbs in my apartment are compact fluoroescent, and in some cases of lesser luminosity than the ones they replaced. All told, if every light bulb in the place is blazing away, I'm still using less electricity than if only my kitchen and bathroom lights were on before replacing the bulbs. Plus, unless I live here 20 years, it's unlikely any of them will ever need replacing. It's a little thing, but if everyone did...

Princeton economist and New York Times columnist Paul Krugman (sub.req.) points out that serious energy conservation does not equal economic disaster: [T]he assumption, explicit or implicit, that any substantial cut in energy use would require a drastic change in the way we live...is false. Let me tell you about a real-world counterexample: an advanced economy that has managed to combine rising living standards with a substantial decline in per capita energy consumption, and managed to keep total carbon...

I'm David Braverman, this is my blog, and Parker is my 8-month-old mutt. Here are the main topics on the Daily Parker: Parker, my dog, whom I adopted on September 1st. Biking. I ride my bikes a lot. Last year I prepared for two Century rides but, alas, my gallbladder decided to explode a week before the first one. I might not have a lot to say until later in the spring, but I have big plans in 2007. Jokes. All right, I admit: when I'm strapped for ideas, sometimes I just post a dumb joke. Politics. I'm...

It seems the weather forecast was correct: The 10 am (1600 UTC) temperature at O'Hare was 2°C, the first time it's been above freezing in Chicago since January 27th, and only the third time since January 15th. I'm going to go outside and bask in the warmth right now...

I may have had my fill of snow, but Parker hasn't: The consensus at the play group yesterday evening was that the warmer weather will turn the park into a mud pit, which the dogs will love almost as much. It's still not April, I guess. There is one aspect of the snow that Parker won't miss, I think: Poor guy.

It's possible that the temperature in Chicago could go above freezing this afternoon for the first time since January 27th. This is the longest stretch of below-freezing weather we've had since I returned home in 2000. Hey, I like records as well as the next athlete, but I'm pretty tired of this one. Stay tuned.

I don't know what Parker was saying to Dexter, but it does look like Dexter is taking the kid under his wing, so to speak: Also, I'd like to point out that neither of them cared about the -26°C wind chill, but Dexter's dad and I sure did. Pretty sunrise, though:

So I'm walking home at 8:15 pm, and I hear Civil Defense sirens. I'm just old enough to find the sound chilling. When I was a kid, CD sirens meant "tornado" or "Soviet missile attack." They sounded for about two full minutes, which I thought was gratuitious. See, Evanston, Ill., sounded their CD sirens tonight to tell everyone to move their cars, just in case people missed the 20 cm of snow on the ground (parking restrictions take effect after 5 cm of snow). I also found out, this storm has dropped more...

The temperature in Chicago hasn't gotten above freezing since the 27th, and we're getting more snow—50 mm so far today. At least it's warmer: for 7 of the past 9 nights the temperature has fallen below -18°C, but right now it's a balmy -3°C. Oh, who am I kidding? Syracuse, N.Y., has over 30 cm of snow on the ground, which is nothing compared with the 3 m reported in parts of nearby Oswego County. And up in Crane Lake, Minn., it's -31°C, and not likely to get warmer any time this week. I guess it's not...

The Winter Solstice happens today at 6:22 pm CST (00:22 UTC).

I also forgot to mention, because it happened while my office DSL was down (cutting off my Web servers from the world), that this past Friday had the earliest sunset of the year in the Northern Hemisphere. Ordinarilly at a juncture like this I would write a dissertation on why the earliest sunset precedes the latest sunrise by four weeks, or why neither coincides with the solstice, but I'll spare you for now. No, the sun is setting later now, but the sun is also rising later, until January 4th, sorry to...

The weather this weekend has obviously helped the CTA. Already by 9 this morning they had almost completed the Church St. viaduct replacement: Also, a few days ago I posted a photo of the ivy on our building. Two days later, the leaves had fallen. Before and after: Must be autumn.

When we got Parker just over a month ago he was timid, to say the least. He would whine and whine if one of us left the room, apparently not realizing that we were still part of his life or that he could just follow us into the other room. He was terrified of cars zooming down our block. The first time I tried to take him for a walk, a runner came towards us; Parker got so spooked that he yanked the leash out of my hand and retreated behind a neighbor's bushes. He couldn't negotiate the stairs on our...

If you don't mind downloading 25 Mb, you can see the short video I took of the cicada who attached herself to my screen while I was working yesterday. To get the full experience turn your speakers up to 11. Those things are ridiculously loud. They start to come out in Northern Illinois mid-June, and by mid-August they're everywhere. Then, suddenly, around Labor Day, they disappear for another year. Someone has a cicada blog you might want to check out, if you're into cicadas. By the way, Chicagoland...

Anne is stuck in Washington because of storms in Chicago...sort of: O'Hare International Airport was experiencing [hour-long] delays, she said, but the airport's flight schedule also had been interrupted by technical problems at a Federal Aviation Administration facility in Elgin. [Chicago Transportation Dept. spokeswoman Wendy] Abrams said the delays were expected to continue throughout the early evening. The National Weather Service in Romeoville issued a Severe Thunderstorm Watch, which will remain...

Today was the hottest July day ever in London: 35°C (95°F). At this writing it has cooled somewhat, to 34°C (93°F)—but it's still 36°C (97°F) in Paris where the Health Ministry is blaming the heat on nine deaths (French). The Times of London reports: Today has been the hottest July day ever with temperatures eclipsing 36 degrees (97°F) in Surrey—surpassing the previous record which has been held since 1911. At 3pm, Charlwood in Surrey was the hottest place in the country, with Heathrow close behind...

I had planned to go for a quick bike ride this morning, but that doesn't look like a lot of fun at the moment: But yesterday Anne and I went for a hike through the Ryerson Conservation Area in Riverwoods, Ill., which was a lot of fun: I am especially glad that I could single-handedly feed thousands of starving mosquitos. Anyway, we chose Ryerson after reading Ted Villaire's 60 Hikes within 60 Miles, which Anne picked up earlier in the week. We recommend the book to anyone who (a) lives in or near...

I love the Straight Dope: Q: I have asked flight attendants on airplanes all over the world. No one knows. No one even hazards a wild guess. ... Why doesn't the plastic bag inflate? Since it doesn't, what is it for? First an inside secret: the bag does inflate, but only when you exhale. Here's the deal. Passenger oxygen masks give you a continuous flow of oxygen (as opposed to oxygen on demand, which only flows when you inhale). The oxygen obviously can't flow into your lungs while you're exhaling, so...

The National Hurricane Center is monitoring Tropical Depression 1, currently in the Carribean but expected to move up the Florida coast this week: AT THIS TIME...THE MAIN THREAT FROM THE DEPRESSION IS HEAVY RAINFALL. THE DEPRESSION IS EXPECTED TO PRODUCE TOTAL RAINFALL ACCUMULATIONS OF 10 TO 20 INCHES OVER THE WESTERN HALF OF CUBA...WITH ISOLATED TOTALS OF 30 INCHES OVER THE HIGHER TERRAIN. THIS COULD CAUSE DEVASTATING FLASH FLOODS AND MUD SLIDES. GRAND CAYMAN ISLAND HAS REPORTED 22.72 INCHES OF RAIN...

If you're not from Chicago, you should visit in early June or mid-September. It's 22°C (72°F) and crystal clear. Tomorrow I'll be in fog central; today I'm enjoying the best of the Midwest.

I had planned to take two co-workers up for a sightseeing flight around Nashua last Tuesday, but the 500-foot ceilings and 24-knot winds argued against it. So we postponed until today. The terminal area forecast right now calls for northeast winds at 14 gusting to 24 knots with 5,000-foot ceilings, with both winds and ceiling diminishing to 12 knots and 1200 feet respectively by 9pm (01:00 UTC). So, once again, I'll use the #1 Aviation Safety Procedure: "staying on the ground." Phooey. I wanted to fly.

First, the House last night passed a campaign-finance package last night on a strict 218-209 party-line vote: The House approved campaign finance legislation last night that would benefit Republicans by placing strict caps on contributions to nonprofit committees that spent heavily in the last election while removing limits on political parties' spending coordinated with candidates. Lifting party spending limits would aid Republican candidates because the GOP has consistently raised far more money than...

The city of Eureka, Nunavut, in way-Northern Canada, has its first sunrise of the year today around 11:30 CT (17:30 UTC). Technically the sun never actually gets above the horizon, but a tiny bit of it will scrape along the southern horizon for about an hour before disappearing until tomorrow. Eureka is typically the northernmost weather station that sends hourly reports to NOAA, and this time of year it's almost always on the world's coldest places list. For example, at this writing, Eureka is -41°C...

Ah, this is more like it. Chicago in January: Windy, snowy, drizzly, and just above freezing. Yum.

A quick check of email showed me a notice from NOAA that the 27th tropical storm of the most active season in recorded history had formed: ...LATE SEASON TROPICAL STORM...THE 27TH OF THE YEAR...FORMS IN THE EASTERN ATLANTIC... AT 1 PM AST...1700Z...THE CENTER OF TROPICAL STORM ZETA WAS LOCATED NEAR LATITUDE 25.0 NORTH... LONGITUDE 36.9 WEST OR ABOUT 1070 MILES...1720 KM... SOUTHWEST OF THE AZORES. And we thought the season had already ended. Wow. This is truly historic.

Every day, my dad walks Reggie, his Austrailian shepherd, along the beach. Today, however, it rained. The humans had Gore-Tex® jackets. The dog didn't:

The National Hurricane Center just a few minutes ago released this report: ...TROPICAL STORM EPSILON...THE 26TH NAMED STORM OF THE 2005 ATLANTIC SEASON...FORMS OVER THE CENTRAL ATLANTIC OCEAN... AT 11 AM AST...1500Z...THE CENTER OF TROPICAL STORM EPSILON WAS LOCATED NEAR LATITUDE 31.6 NORTH... LONGITUDE 50.4 WEST OR ABOUT 845 MILES...1360 KM...EAST OF BERMUDA AND ABOUT 1395 MILES...2245 KM... WEST OF THE AZORES ISLANDS. For those of you keeping score at home, this means we've seen 7 more named storms...
