Minnesota Was Much Hotter When There Was Much Less CO2

Ada, Minnesota has had eighty days over 100 degrees since 1895. More than half of those days occurred during the 1930s. All but one occurred with CO2 below 350 PPM. The current decade has produced no 100 degree days in Ada.

James Hansen wrote this last summer :

Published August 6, 2012

Recent heat waves that have triggered wildfires, droughts, and heat-related deaths in the United States and around the globe “almost certainly would not have occurred” without global warming—and will become more routine in coming years, NASA climate scientist James Hansen says.

Heat Waves “Almost Certainly” Due to Global Warming?

Besides the fact that his 2012 comments are complete nonsense, they are in direct contradiction to what he wrote in 1999.

Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath.
