The ongoing March heat wave being experienced in the Midwest Untied States is one of the most extreme heat events in U.S history, Jeff Masters of Weather UndergroundÂ has reported.
Many historical records have been broken throughout the event, including aÂ 94Â°F day in Winner, South Dakota, and a 79Â°F in International Falls, Minnesota.Â Chicago weather has involved five straight days of temperatures aboveÂ 80Â°F. Â The city has experienced the hottest temperature on record for so early in the year â€“ 82Â°F on both Friday and Saturday. To give an indication of how extreme this is, the average temperature in August in Chicago isÂ 82Â°F.
Masters said that while the blocking pattern responsible for the heat wave is natural, “it is very unlikely that the intensity of the heat would have been so great unless we were in a warming climate. He points out that eminent climate scientist Dr. James Hansen from N.A.S.A. has written recently about recent occurrences ofÂ more intense heat waves, in relation to the summer heat waves in both Texas and Moscow (see our recent postÂ James Hansen Warns â€˜Climate Diceâ€™ Loaded For Extreme Weather Events).
Even President Obama, not being one lately to talk much at all about climate change, has admitted being “a little nervous” aboutÂ the March heat wave, while at a fundraiser in Chicago hosted by Oprah Winfrey. Obama stated,
â€œItâ€™s warm every place. It gets you a little nervous about whatâ€™s happening to global temperatures. But when itâ€™s 75 degrees in Chicago in the beginning of March it gets you thinkingâ€¦â€
â€œSomethingâ€™s wrong,â€ Oprah interrupted.
â€œYeah,â€ Obama said. â€œOn other hand we really have enjoyed the nice weather.â€
What do you make of this unseasonably warm weather in the United States? Nothing to be concerned about, or yet more evidence we are on a dangerous path?
