Extreme Weather in the US: Is It Climate Change or a Historical Pattern?
3. This Argument Doesn't Hold Up
A derecho is a somewhat common weather event. In fact the phenomenon was identified and given a name way back in the 1880s. And as for the recent heat wave, yes it's hot. But it pales in comparison to the most severe heat wave to hit North America in modern history, the 1936 North American Heat Wave, which hit in the middle of the Great Depression and the Dust Bowl of the 1930s. Incidentally, the 1936 North American Heat Wave followed one of the coldest winters on record at the time -- a six-month weather swing far more extreme than what North America has seen over the last six months.
