I'm having a series of productive days lately, which has taken me away from wasting a bunch of time. So for example, I haven't yet today read these items:
And all of this on the coldest day in two years, in a month in which most days have had no sunlight. But hey, we're still having an abnormally-mild winter, so again, we're not complaining.
It's every other Tuesday today, so I'm just waiting for the last continuous-integration (CI) build to finish before deploying the latest software to our production environment. So far, so boring, just the way I like it. Meanwhile, in the real world:
- In a symbolic but meaningless vote, all but 5 Republican members of the US Senate voted to let the XPOTUS off the hook for inciting an insurrection against, well, them, as this way they believe they get to keep his followers at no cost to themselves. If this past year were a novel, the next sentence might begin with "Little did they know..." Which, you know, describes those 45 Republicans to a T.
- Dutch police arrested more than 180 people in Amsterdam and Rotterdam for rioting against Covid-19 lockdowns: "A leading Dutch criminologist, Henk Ferwerda, said the riots involved 'virus deniers, political protesters and kids who just saw the chance to go completely wild – all three groups came together.'"
- Air travelers across the US can rejoice that CNN Airport News will go away on March 31st.
- Over 1 teratonne of ice melted over each of the past few years, increasing concerns about global sea level rises.
- Two mathematicians argue that time-travel paradoxes don't exist, because the universe routes around them.
Finally, snow continues to fall in Chicago, so far accumulating to about 100 mm by my house and as of noon about 125 mm at O'Hare. Calling this a "snowstorm" seems a bit over the top as it's coming down at under 10 mm per hour and forecast to stop before too long. Plus it's barely below freezing for now—but forecast to cool down to -11°C by Wednesday night before creeping above freezing Friday and Saturday. So we might have a blanket of snow for a bit. Still, it's the most snow we've gotten all season, with less than 5 weeks to go before meteorological spring starts March 1st. I'm OK with this mild winter, though it might presage a very hot summer.
Even though things have quieted down in the last few days (gosh, why?), the news are still newing:
Finally, last August's derecho caused "the most damage in the least amount of time" of any weather disaster on record.
We've only had six days where the temperature stayed below freezing since November 1st, and the third year in a row where we've not had a temperature below -18°C by this point. This shouldn't surprise anyone who knows that 2020 either tied or set the record for warmest year in history:
[An] analysis of global temperatures, by the NASA Goddard Institute for Space Studies and released Thursday, found that 2020 was slightly warmer than 2016. But the difference was insignificant, the institute’s director, Gavin Schmidt, said in an interview.
“Effectively it’s a statistical tie,” he said.
Other analyses issued Thursday, one by the National Oceanic and Atmospheric Administration and another by Berkeley Earth, an independent research group in California, found that 2020 was slightly cooler than 2016, as did one published last week by the Copernicus Climate Change Service in Europe. But the difference was small enough to not be statistically significant.
With the 2020 results, the last seven years have been the warmest since the beginning of modern record-keeping nearly a century and a half ago, Dr. Schmidt said.
But the numbers are only a small part of the story. As climate scientists have predicted, the world is seeing an increase in heat waves, storms and other extreme weather as the planet warms, and in disasters like droughts, floods and wildfires that result. Last year offered no respite, with record fires in Australia and California, and severe drought in central South America and the American Southwest.
Some climate forecasters had thought that the arrival of cooler sea-surface temperatures in the Pacific Ocean — part of the recurring global climate phenomenon called La Niña — would tamp down temperatures this year. It is difficult to quantify the influence of La Niña, but it is clear that any effect was eclipsed by the emissions-related rise in temperatures.
As I've said for a very long time, global warming will make Chicago a much more comfortable place to live for a century or two at least, though changing precipitation patterns could seriously alter the Great Lakes' shorelines in ways that make us much less comfortable later on.
We're so close to ending 2020 that I can almost taste it. (I hope to be tasting tacos in a few minutes, however.) True to form, 2020 has apparently decided not to leave quietly:
Finally, the Washington Post's Michael Rosenwald reports that Bloom asked 28 historians to determine whether 2020 was the worst year ever. It wasn't even close.
Sure, the temperature got down to -13°C this morning, but we haven't had any real cold yet this winter, despite the 25°C temperature drop yesterday. Yesterday's high of -3°C was the first below-freezing high temperature of the winter. We've only had that occur this late in the year on five other occasions—two of them this century. Chicago gets its first below-freezing high temperature by November 24th on average. Yesterday's event ties 2001 and is only a few days before the latest occurrence of January 1st (2013 and 1924).
The Climate Prediction Center forecasts above-average temperatures all winter:
Also in early 2021 we should get the revised climate normals as the 1991-2020 data supersedes the 1981-2010 data we've used for 10 years. We expect normal temperatures to rise in most parts of the United States, with dramatic jumps expected in Alaska. Even with the revised numbers, we expect above-normal temperatures to outnumber below-normal temperatures for the next decade.
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:
Finally, it's very likely you've made out with a drowning victim from the 19th century.
Iceberg A-68a broke off from Antarctica's Larsen Ice Shelf in September 2017. It has drifted more or less intact since then, and later this month will very likely hit South Georgia Island in the south Atlantic:
[UK] Government officials have been tracking the 4,200-square-km iceberg closely with the help of the British Royal Air Force, who conducted a reconnaissance mission over the iceberg capturing photos and videos of the large mass.
“The sheer size of the A68a iceberg means it is impossible to capture its entirety in one single shot,” British officials said in a statement.
As of now, the iceberg is just 150 kilometers from the territory, according to BBC News. If it does collide with South Georgia Island scientists warn that it could threaten the wildlife ecosystem and animals' access to food. A large number of whales, seals, and penguins feed off the coast of South Georgia.
This NASA photo from November 5th shows the berg about 200 km from where it is today:
South Georgia Island is a British overseas territory.
We've got a day and a half of autumn left in Chicago. Here's what I'm reading on a lazy Sunday:
And finally, new research shows that the pyroclastic flows from Vesuvius in 79 CE turned people's brains to glass. Yummy.
