The temperature at Inner Drive Technology World HQ has crept all the way up to -0.4°C (31.3°F), close enough to freezing that it would take hours to get frostbite. But you'd still get frostbite, so it's not quite where we want it. Officially at O'Hare it's -0.6°C (31.0°F), the warmest since 9pm on Friday January 16th.

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.)

Now that I've had a good night's sleep and the sun is out for the first time all year, I have the energy to start reading the news again. On January 2nd, most of the stories are about things that have changed since Wednesday: Chicago had 416 murders in 2025, the lowest number recorded since 1965 when the city had 620,000 (23%) more people. In 2025, the hottest temperature recorded at Inner Drive Technology WHQ was 34.3°C (93.7°F) on June 23rd; the coldest was -20°C (-4°F) January 21st. Officially at...

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 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.

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...

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...

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...

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...

Cassie and I survived our 20-minute, -8°C walk a few minutes ago. For some reason I feel like I need a nap. Meanwhile: James Fallows remembers his old boss Jimmy Carter, and puts his presidency in perspective for the younger generations. Paul Krugman reminds the Republican Party that California contributes more to the country's GDP than any other state, so maybe cut the crap threatening to withhold disaster relief? ProPublica goes "inside the movement to redirect billions of taxpayer dollars to private...

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.

Lots of stories in the last day: Are we about to see a historic change at the top of the Democratic ticket? What's the connection between vice-president nominee JD Vance (R-OH) and Hulk Hogan? Or between JD Vance and Faust? Or between JD Vance and your menstruation cycle? The City of Chicago has approved tearing down the Eamus Catuli building on Waveland. We actually had 25 tornados on Monday. Twenty five. Finally, comic genius and Chicago native Bob Newhart has died at age 94. He was a national treasure.

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...

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...

I took Cassie out at 11am instead of her usual 12:30pm because of this: The storm front passed quickly, but it hit right at 12:30 and continued for half an hour with some intensity. It'll keep raining on and off all day, too. Other things rained down in the past day or so: Robert Wright points out the obvious, warning that the XPOTUS was (and would be again if re-elected) way, way worse than President Biden on Gaza. Jennifer Rubin points out the obvious, echoing the warnings of Republican...

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.

The weather forecast for Munich doesn't look horrible, but doesn't look all that great either, at least until Saturday. So I'll probably do more indoorsy things Thursday and Friday, though I have tentatively decided to visit Dachau on Thursday, rain or not. You know, to start my trip in such a way that nothing else could possibly be worse. Meanwhile, I've added these to yesterday's crop of stories to read at the airport: Deciding to be "stabbed, to live to see another day," the Republican-controlled...

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....

Wouldn't that be nice? Alas, people keep making them: Harvard University president Claudine Gray finally threw in the towel. Researchers at Rutgers University have identified clear patterns in TikTok hashtags that suggest direct Chinese Communist Party interference with the app. Though the WMO and NCDC haven't confirmed it officially, 2023 appears to have been the hottest year on record—and 2024 will be warmer. Vishaan Chakrabarti, the former director of planning for Manhattan, outlines a plan to make...

Due to an odd combination of holidays, a use-it-or-lose-it floating holiday, and travel, I'm just about done with my first of four short work-weeks in a row. Not that there's anything wrong with that. Of course, since I would like to finish the coding problem I've been working on before I leave today, I'll have to read some of these later: Josh Marshall thinks it's hilarious and pathetic that Rep. Lauren Boebert (R-CO), realizing she can't win against a Democrat in her own district, said she'll run in...

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.

Chicago experienced its warmest October 1st through 4th ever, clocking in at 24.4°C, before a cold front pushed through this morning. Many of my friends, plus another 25,000 runners, look forward to Sunday's Chicago Marathon and its predicted 7°C start temperature going up to a high of 14°C. So, with real autumn temperatures finally upon us, let us chill out: David Frum puts the House Speaker nonsense in the context of a political party unable to deal with reality. Greg Sargent agrees, saying the...

The temperature has crept up towards 34°C all day after staying at a comfortable 28°C yesterday and 25°C Friday. It's officially 33°C at O'Hare but just a scoshe above 31°C at IDTWHQ. Also, I still feel...uncomfortable in certain places closely associated with walking. All of which explains why I'm jotting down a bunch of news stories to read instead of walking Cassie. First, if you have tomorrow off for Labor Day, you can thank Chicago workers. (Of course, if you have May 1st off for Labor Day, you can...

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...

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.

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...

At my day job, we just ended our 80th sprint on the project, with a lot of small but useful features that will make our side of the app easier to maintain. I like productive days like this. I even voted! And now I will rest on my laurels for a bit and read these stories: If you don't worry that the entire US Supreme Court has the technical expertise of your 99-year-old great uncle, perhaps you should? Treasury Secretary Janet Yellen explains how giving economic aid to Ukraine benefits the West. In part...

I spent way more time than I should have this morning trying to set up an API key for the Associated Press data tools. Their online form to sign up created a general customer-service ticket, which promptly got closed with an instruction to...go to the online sign-up form. They also had a phone number, which turned out to have nothing to do with sales. And I've now sent two emails a week apart to their "digital sales" office, with crickets in response. The New York Times had an online setup that took...

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...

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...

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...

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...

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...

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...

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 temperature bottomed out at -14.4°C around 1:30 am, and has climbed ever so slowly since then to -0.3°: Will we get above freezing? The forecast says yes, any moment now. But the sun will set in about 5 minutes. Anyway, a guy can dream, right? Meanwhile, Chicago's teachers and schools have agreed to let the kids back tomorrow, even as the mayor herself tested positive for Covid. And the Art Institute's workforce has formed a union, which will operate under AFSCME. And that's not all: It turns out...

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...

Every so often in the winter, a cold front pushes in overnight, giving us the warmest temperature of the day at midnight. Welcome to my morning: The sun actually came out a few minutes ago—right around the time the temperature started dropping faster. The forecast says temperatures will continue falling to about -12°C by 3pm, rise ever so slightly overnight and tomorrow, then slide on down to -17° from 3pm tomorrow to 6am Friday. And, because it's Chicago, and because the circumpolar jet stream looks...

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...

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...

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...

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...

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....

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"...

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...

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...

It's the first day of November 2019, the month in which the 1982 classic film Blade Runner takes place. Los Angeles has a bit of haze today from wildfires in the area, but I'm glad to report that it isn't the environmental disaster portrayed in the movie. No flying cars, no replicants, and no phone booths either. In other news: Chicago woke up to 75 mm of snow on the ground from the largest Halloween snowfall in the city's history. Despite the white stuff on the ground, a study at CBRE Group and...

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...

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.

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...

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...

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...

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...

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...

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.

It's not all about PETUS today: Via AVWeb, the FAA has issued an airworthiness directive requiring owners of Boeing 787-8 airplanes to reboot them at least every 21 days. I am not making this up. Trump, never a fan of intelligence of any kind, is sticking his fingers in his ears about Russian hacking of our election. Jeet Heer warns that this yet another way Trump is very dangerous. Plus, he's lying about the CIA's role in the Iraq WMD fiasco. It wasn't the CIA who lied; it was the Administration. By...

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.

I have three books in the works and two on deck (imminently, not just in my to-be-read stack) right now. Reading: Neal Stephenson, Seveneves. Christopher Dickey, Our Man In Charleston. Gene Kim, et al., The Phoenix Project. On deck: Kevin Hearne, "Iron Druid Chronicles" book 8: Staked. Kim Stanley Robinson, "Mars" trilogy book 2: Green Mars. Meanwhile, I have these articles and blog posts to read, some for work, some because they're interesting: Deeply Trivial dissects the bogus claim that six coin...

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...

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.

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.

...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...

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...

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.

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...

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...

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.

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.

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...

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...

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...

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...

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...

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]...

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...

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...

Usually, my July visits to my family in San Francisco allow me to get away from Chicago's oppressive heat. This year, both cities are about the same, San Francisco just a little warmer than usual, and Chicago...well, it's the coolest July of my life: July has slipped to the coolest to date here in 42 years—its 68.7°F degree average temperature running nearly 5 degrees behind the long-term (138-year) average. Friday's 70°F high was the first time in 53 years a July 17 temperature failed to rise above...

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.

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...

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.)

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

I took a walk this afternoon and wound up here: And then this happened: Cool.

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...

As threatened, it hit 37°C (99°F) in Chicago today, making it possibly the hottest July 31st on record. We won't know for sure until tomorrow. From July 1st until today the average high temperature in Chicago was 29.6°C (85.3°F), modestly above normal, but not quite like those in Jamie's and Angela's home cities, which were 32.2°C (90°F) and 32.4°C (90.4°F), respectively. As Angela pointed out, this is much more normal for Atlanta than it is for here, but that doesn't make it any more pleasant in either...

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...

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.

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.

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:
