The Illinois State Climatologist reports that 257 daily high temperature records have been set statewide this month. He worries that the early warmth could cause damage to agriculture as similar events did in 2007 and 2012:
A batch of crocus on the south side of our office building is a reminder of the impacts of warm weather in February. Both January and February have been mild. But on top of that has been a record-setting streak of 60s and 70s in the past week. As a result, many early season perennials such as crocus are coming out a little early. In the past, such warm weather has made any early vegetation vulnerable to the inevitable freeze later on. In 2007 and 2012, a similar scenario played out with damage to corn, winter wheat, alfalfa, and fruit crops across Illinois. The 2007 event was well documented in this report.
Meanwhile, a cold front pushed through last night with dog-frightening thunder, so it's now just above freezing in Chicago and promises to drop to about -5°C this weekend.
I hope to read these articles sometime this year.
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.
We haven't gotten 25mm of snow in Chicago since December 19th, and the forecast for the next week is precipitation-free—57 days of snow-free weather so far. The record is 83, which we'll break if we don't get that much snow before March 12th. This is unlikely most years, but this year, the climate predictions look promising.
Stay tuned. We could always get a blizzard. It's February, after all.
Stuff I'll read before rehearsal today:
Back to the mines...
Welcome to February, in which I hope to increase my pathetic blogging rate (currently 1.23 per day for the last 12 months). Of course, even taking a day off to catch up on things doesn't seem to be helping, because I have all of these articles to read:
So, a lot to read. And still almost no time to read it.
Not that the incoming administration cares:
Marking another milestone for a changing planet, scientists reported on Wednesday that the Earth reached its highest temperature on record in 2016 — trouncing a record set only a year earlier, which beat one set in 2014. It is the first time in the modern era of global warming data that temperatures have blown past the previous record three years in a row.
The findings come two days before the inauguration of an American president who has called global warming a Chinese plot and vowed to roll back his predecessor’s efforts to cut emissions of heat-trapping gases.
The heat extremes were especially pervasive in the Arctic, with temperatures in the fall running 20 to 30 degrees Fahrenheit above normal across large stretches of the Arctic Ocean. Sea ice in that region has been in precipitous decline for years, and Arctic communities are already wrestling with enormous problems, such as rapid coastal erosion, caused by the changing climate.
Since 1880, NOAA’s records show only one other instance when global temperature records were set three years in a row: in 1939, 1940 and 1941. The Earth has warmed so much in recent decades, however, that 1941 now ranks as only the 37th-warmest year on record.
Meanwhile, in Chicago this January week, it feels like March.
January 3rd is one of my favorite days of the year in astronomy, because it's the day that the northern hemisphere has its latest sunrise of the winter. This morning in Chicago, the sun rose at 7:19 (though it rose behind a thick rainy overcast), just a few seconds later than it rose yesterday. But tomorrow it will rise just a few seconds earlier, then a few more, until by the end of January it'll rise more than a minute earlier each day.
Meanwhile, thanks to the eccentricity of our orbit around the sun, sunsets have gotten later since the first week of December. It's noticeable now; today's sunset at 16:33 is 14 minutes later than the earliest sunset on December 7th. A week from now sunset is at 16:40; a week later, at 16:48.
By January 31st we will see more clearly that the dark days of northern hemisphere winter are ending. Sunrise at 7:04 and sunset at 17:04 gives us 10 full hours of sunlight, 47 minutes more than we'll get today.
So even though the 115th Congress opened today in Washington, with the House Republicans proposing to geld their own ethics watchdog (and why would they want to do that, hmmm?), at least things will literally get more sunny throughout the country every day for the next six months.
