A Holocaust denier is someone who denies that the Holocaust occurred. We have a new breed of deniers on the loose, those who apparently believe that the Dust Bowl never happened.
Lots of claims this week that the current drought affecting a few states is the worst drought in history. There have been numerous much longer lasting and much more widespread droughts – most notably the 1930s. As Hansen said :
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.
