When is the next ice age?

Remember the blockbuster hit The Day After Tomorrow? Well, thanks to climate change, that doomsday scenario could become reality, albeit a bit more slowly than in the movie.

From The Thom Hartmann Reader:
"Right through the worst of the Bush years and into the present, Thom Hartmann has been one of the very few voices constantly willing to tell the truth. Rank him up there with Jon Stewart, Bill Moyers, and Paul Krugman for having the sheer persistent courage of his convictions."
Bill McKibben, author of Eaarth
From Screwed:
"Hartmann speaks with the straight talking clarity and brilliance of a modern day Tom Paine as he exposes the intentional and systematic destruction of America’s middle class by an alliance of political con artists and outlines a program to restore it. This is Hartmann at his best. Essential reading for those interested in restoring the institution that made America the envy of the world."
David C. Korten, author of The Great Turning and When Corporations Rule the World
From Screwed:
"I think many of us recognize that for all but the wealthiest, life in America is getting increasingly hard. Screwed explores why, showing how this is no accidental process, but rather the product of conscious political choices, choices we can change with enough courage and commitment. Like all of Thom’s great work, it helps show us the way forward."
