Best counterargument to those calling Al Gore "hysterical"

Digby:

I think my favorite thing about the know-nothing wingnut argument is that Al Gore is said to be all hysterical on this silly little problem by the same people who are screeching like howler monkeys that the oceans don't protect us anymore and "they're" comin' to kill us in our beds! The fact that ridding ourselves of our dependence on oil might mitigate both of these problems escapes their notice.

A political party that has hitched its wagon to the Four Horsemen of the Apocalypse for the last five years after a president ignored a very real threat of an attack against the U.S. has nothing to say about Al Gore "overdramatizing" the problems we face from unfettered global warming.
