So far, this April ranks as the 2nd coldest in Chicago history. We had snow this past weekend, and we expect to have snow tonight—on April 18th.
So it may come as a surprise to people who confuse "weather" and "climate" that, worldwide, things are pretty hot:
The warm air to our north and east has blocked the cold air now parked over the midwestern U.S. Europe, meanwhile, feels like August. And Antarctica feels like...well, Antarctica, but unusually warm.
Note that the temperature anomalies at the bottom of the image above are based on the 1980-2010 climate normal period, which was warmer than any previous 30-year period. In other words, the poles may be 3-5°C warmer than normal now and also 4-7°C warmer than any point in recorded history.
At least, historically, a cold spring means a cool summer here. Lake Michigan is a very cold 5°C today, a few degrees below normal for this time of year, and a huge sink for summer heat later on. Here's hoping, anyway.
