Prepare for more panic talk  about the end of the world as Dr. James Hansen, a leading global warming alarmist whose temperature data has come under question , launches a media tour for his new book out this week, 'Storms of My Grandchildren: The Truth About the Coming Climate Catastrophe and Our Last Chance to Save Humanity .'
Hansen is director of NASA's Goddard Institute for Space Studies  in New York City and an adjunct professor at Columbia University's Department of Earth and Environmental Sciences.
One place I know he'll pop up this week is on the Late Show with David Letterman where he's scheduled to appear Thursday night  as the second guest after actress Kate Hudson.
Letterman long ago drank the Kool-Aid :
Now here the other day I hear that the Senate, they were monkeying around, they had some kind of climate change bill and it just ran out of gas and it dropped dead. And people are all talking about, "okay we're going to change the emissions by 2035, by 2020." That's too late. I mean, it's a hundred degrees now! In 2020, honest to God, what's it going to be?
