Big cats vs big dogs

This surprised me. One or more mountain lions in Washington state has decided that wolves taste good:

Washington Department of Fish and Wildlife (WDFW) staff have documented cougars killing six collared wolves since 2013—almost 30 percent of the 21 documented natural wolf mortalities in the state. "That's huge if that trend holds and is representative of the entire population [in the state]," says Trent Roussin, a WDFW biologist. The kills involve multiple wolf packs in different areas of Washington.

Such kills are rare elsewhere in the U.S. West, where more wolves are on the landscape since their reintroduction to Yellowstone National Park, which is mostly in Wyoming, and central Idaho in 1995. Today Montana and Idaho have over five times more wolves than Washington.

While a wolf pack tends to have an advantage over a single cougar—sometimes running it up into a tree or kicking it off a carcass to scavenge for themselves—a cougar excels in a one-on-one ambush. All but one of Washington's wolf kills involved lone wolves.

"Everyone always assumes wolves have the upper hand," says ecologist Mark Elbroch, the leader of Panthera's Puma Program. "But that's not always the case."

I don't expect my own wolf would do well in a fight against a cougar—or a Dachshund, for that matter—but I had no idea cougars hunted actual wolves. You know I'll always root for the dogs over the cats, though.

Incoming weather system

We get blizzards and heat waves in Chicago. Guess which one we get tomorrow? The forecast still calls for 36°C temperatures with heat indices around 42°C. But Inner Drive Technology World Headquarters is only 2.1 km from Lake Michigan. At Chicago's official weather station at O'Hare, which is 23.3 km from the Lake, it looks a bit grimmer: 37°C with a heat index of 43°C.

WGN's Tom Skilling and Bill Snyder admit that some of the models call for 38°C or 39°C, but they manually adjusted the forecast because the models don't all agree:

Temps at or above 100 in Chicago are rare. Since official records began in the city 153 years ago in 1871, there have only been 62 days with highs at or above 100 degrees. And at the Midway Airport site on the city’s South Side where weather observations have been archived since 1928, on only 92 occasions over that 95 year period has a reading of 100 degrees or higher occurred.

There’s a reason for the scarcity of such EXTREME HEAT. The fact is, nature finds ways to derail the development of such intense heat. That’s why as forecasters, we’re careful about predicting such readings and must ALWAYS MAKE IT CLEAR there are forces which have been around over the term of official weather observations which work to keep a 100-degree readings from happening. The best evidence currently available suggests a 99-degree high is a strong possibility Wednesday — a reading just one degree shy of a triple-digit reading and, if it occurs, a record breaker which would exceed the old August 23rd record Chicago high of 97 degrees. Thursday could see a 100-degree high, but the potential for a front to sag into the area and turn winds off the lake at some point in the afternoon isn’t completely off the table. ALSO, though not expected at the moment, the development of thunderstorms — even if close-by — can send a cooling outflow of air into the area aborting a 100-degree temperature.

What’s interesting is even if a cold front comes into the picture Thursday, the convergence of winds along that front can lead to heating which would be capable of sending Chicago-area highs to 100, which would tie the record for August 24 and become a windshift behind the front that would send temps falling.

(Note that WGN, unlike 95.6% of the world's population, still uses the obsolete Fahrenheit scale in its reports.)

In other words, 36°C is the low estimate for the heat we're about to get. If the temperature does get above 38°C, though, it will be the first time since July 2012 that we've experienced anything that hot here.

At least we have trees to shade our walks in my part of the city. Writer Tiffany Owens Reed lives in Waco, Texas, whose urban design she says better suits lizards than people:

Before the advent of air conditioners, hot weather was something that architects and city planners had to respond to with creativity. The weather was something to adapt to, to work with, to manage…not merely to escape. For example, in Bologna, architects responded to hot weather by building a network of covered walkways that allowed pedestrians to wander the city fully shaded except for the brief moments during which they crossed the street from one walkway to another. We can see a similar sentiment at play with the ornate covered passageways of Turin, Italy. In the U.S. when touring old cities like Charleston, South Carolina, we can see evidence of similar accommodations in the deep, wide porches circling old houses.

Seeing the city as a destination for humans to inhabit and explore, and as a conduit for experiencing nature would lead to different design priorities, similar to what we see with public splash pads, rivers cleaned up for public swimming, or railways turned into parks for lounging (as in the case of Manhattan’s Highline)

If the main assumption is that humans won’t be spending time outside, that discourages these kinds of weather-considerate features and what we get instead is what my husband and I have come to call “lizard architecture”: a homogenous style of design imported to cities by developers who lack regionally specific weather consciousness and that would probably be more conducive to designing for reptiles than for humans.

Lizard architecture might not be the most scientifically accurate name for this style of design, but it provides my husband and me much comic relief as we drive around, spotting massive, unshaded parking lots, exposed outdoor dining areas, and unshaded walkways…design features that make it extremely uncomfortable to be a human outside for extended periods of time. It’s the kind of design that indicates to me an overreliance on technology to solve our discomforts and an inability to imagine cities as spaces where folks might want to experience nature, even when it’s hot. More mindful, human-centric city designers would consider the possibility that humans actually want to be outside, not just as environments to move through as quickly and comfortably as possible.

Our heat wave should end Friday morning, with a cool front coming in from the north dropping temperatures as low as 16°C by Saturday night. Then we head into the last week of summer, with autumn officially beginning next Friday, when I plan once again to try walking a full 42.2 km.

A bit toasty in the Pacific Northwest

Many cities in Washington, Oregon, and Idaho hit all-time record high temperatures yesterday, including 43.3°C in Dallesport, Wash., and 40.6°C in Boise, Idaho. Even Portland, on the ocean side of the Cascades and usually lovely this time of year, hit 39.4°C.

Chicago right now is a decent 27°C, with the moisture from this morning's storms adding a bit of bleck around the Inner Drive Technology World Headquarters. And the roofing contractor had to disconnect one of my A/C units this morning because they mismeasured the placement of a privacy screen, so I might have to sleep on the couch with Cassie tonight. The forecast says 15°C and north-northwest winds, so maybe it'll cool off enough to open windows upstairs. We'll see.

End of day reading list

The XPOTUS continuing to get indicted for trying to steal the 2020 election wasn't the only bit of authoritarian fuckery this week:

Finally, Michael Oher, the subject of the book and film The Blind Side, says the white family that he lived with not lied to him about adopting him, but also used their positions as his conservators to screw him out of compensation from the story of his own life. Which, if you remember, put the white folks up as the heroes. I wish I'd been more surprised and shocked, but no, it tracks.

Today is like May 1st

Since I live in a temperate climate, I think about seasons more than my friends who live in, say, San Jose, Calif. This becomes especially pronounced the closer we get to the equinoxes as the change in daylight hours peak then. On my walk with Cassie earlier today, I started thinking about how actually to quantify the lengthening shadows in autumn.

Here, then, is a chart of the position of the sun in Chicago for the first day of each month, along with its equivalent day on the other side of the equinox. For example, today the sun is about 63° above the southern horizon at solar noon—almost exactly the same as on May 1st. This means also that the day has about the same length (14 hours, 2 minutes), and the sun rises and sets in the same parts of the eastern and western skies, respectively.

Using the code I wrote for Weather Now, it took just a couple of minutes to generate the basic data for this chart. It should make sense right away, except for the column marked "Shadow." That's the length of the shadow cast per unit of hight at solar noon. So, for example, today's 63.3° sun angle gave a 10-meter building a shadow almost exactly 5 meters in length. The two days of the year (in Chicago, anyway) when the sun is 45° above the horizon—giving everything a shadow equal to its own height—are March 13th and September 30th.

Enjoy:

Another thing I found interesting: notice how quickly shadows lengthen in the fall and shorten in the spring. That's what I noticed today, in fact: the east-west sidewalks were completely in shadow at noon today. They haven't been since, oh, the beginning of May.

Now, the date pairs should work for any point on earth, but all the other data will change. If you want to see your own location's sunrise and sunset times, go to Weather Now.

Temperature 26, dewpoint 22

I just got back from walking Cassie for about half an hour, and I'm a bit sticky. The dog days of summer in Chicago tend to have high dewpoints hanging out for weeks on end, making today pretty typical.

Our sprint ends Tuesday and I still have 3 points left on the board, so I may not have time to give these more than a cursory read:

Finally, Andrew Sullivan adapts a column he wrote in August 2001 asking, "why can't Americans take a vacation?" One reason, I believe: all the time and money we spend in and on our cars.

Auto-oriented development is a radical monopoly

Strong Towns summarizes an essay by Ivan Illich in which he explains how drivers, and not cars, are the product of the automobile industry. Cars, and car-focused infrastructure, create the problems that car ownership is supposed to solve in the first place:

[Illich] looks at the ratio of time invested to not just miles, but the utility we extract from that investment. If driving around for three hours allows me to travel 15 miles at 30–45 mph and accomplish three errands, Illich would focus less on the mileage and speed and more on the utility: should it really have cost me three hours (not to mention the gas) to accomplish these three errands, or is there a scenario in which I could have accomplished them in one half or one third of that time?

Auto-oriented thinking would focus on the mileage and speed: look at how much faster I can travel! Look at how far I can go! But if that mileage is mostly just a product of land use laws that spread destinations apart, then it’s a deceptive metric and one that traps cities into thinking that adding more car infrastructure is the only solution to any mobility-related challenges. This would be an example of what Illich calls a radical monopoly: a system in which a tool is presented as the solution to a problem that it causes in the first place. In our cities, cars are presented as the solution to sprawl, dangerous roads, and disconnected neighborhoods. But these design patterns exist because they are necessary to mandate the purchase and use of cars.

Real transit innovation would require setting different goals and setting out to solve real problems, not problems created to ensure the purchase of a machine. The goal for local transit systems shouldn't be to cover more speed at a faster distance. That’s suitable for traveling the world, not for running errands. When thinking about local transit systems, the goal should be to give people back their time and empower them to get more done in less of it.

In other words, if you need to own a car because everything you need is too far to walk, and also because your city hasn't got any other transit infrastructure, then car-oriented development patterns become self-reinforcing.

Illich does some other math:

The model American puts in 1600 hours to get 7500 miles: less than five miles per hour. In countries deprived of a transportation industry, people manage to do the same, walking wherever they want to go, and they allocate only 3 to 8 percent of their society's time budget to traffic instead of 28 percent. What distinguishes the traffic in rich countries from the traffic in poor countries is not more mileage per hour of lifetime for the majority, but more hours of compulsory consumption of high doses of energy, packaged and unequally distributed by the transportation industry.

Someday, probably sooner than most Americans think, we're going to have significantly less energy to expend on driving cars. Again, this is why I live in Chicago. And why I have very little sympathy for people who choose to live in Schaumburg.

Wait, it's August?

While I fight a slow laptop and its long build cycle (and how every UI change seems to require re-compiling), the first day of the last month of summer brought this to my inbox:

  • Who better to prosecute the XPOTUS than a guy who prosecuted other dictators and unsavory characters for the International Criminal Court? (In America, we don't go to The Hague; here, The Hague comes to you!)
  • After the evidence mounted that Hungary has issued hundreds of thousands of passports without adequate identity checks, the US has restricted Hungarian passport holders from the full benefits of ESTA that other Schengen-area citizens enjoy.
  • The US economy continues to exceed the expectations of people who have predicted a recession any day now. (Of course, every dead pool has a guaranteed winner eventually...)
  • After an unprecedented 31 consecutive days enduring temperatures over 43°C, Phoenix finally caught a break yesterday—when the temperature only hit 42°C.
  • Jake Meador explores why about 40 million fewer Americans go to church these days than in 1995.
  • Remember how we all thought Tesla made cars with amazing battery ranges? Turns out, Elon Musk can't do that right, either.
  • American car culture not only gives us unlivable environments, but also discourages the exploration that people in other countries (and I when I go there) do all the time.
  • We should all remember (and thank) USSR naval Captain Vasili Alexandrovich Arkhipov, who vetoed firing a nuclear-tipped torpedo at an American destroyer during the Cuban Missile Crisis 71 years ago.

Finally, Chicago historian John Schmidt tells the story of criminal mastermind Adam Worth, who may have been Arthur Conan Doyle's inspiration for Professor Moriarty.

A sense of place

Not Just Bikes shows the difference between places and non-places in ten short minutes:

Fortunately the part of Chicago where I live has a sense of place that he'd recognize, but you have to cross a stroad (Ashland to the east, Western to the west, Irving Park to the south, Peterson to the north) to get to another place like this.

I also can't help but think that a new culture will arise in a couple of millennia that will look at "the great American roads" as something to emulate. Maybe the Romans had culture critics arguing against expanding the 8-lane highways running through their cities too?

Stuff to read later

I'm still working on the feature I described in my last post. So some articles have stacked up for me to read:

And while I read these articles and write this code, outside my window the dewpoint has hit 25°C, making the 28°C air feel like it's 41°C. And poor Cassie only has sweat glands between her toes. We're going to delay her dinnertime walk a bit.
