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.
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.
