Extreme climate change looms. Another Ice Age could be imminent. The last time it happened, eleven thousand years ago, it took just three years to start. The good news is that Frank Vanderwal is part of a massive international effort to restabilize Earth's climate. At least he refuses to feel helpless before the indifference of the politicians and capitalists who run America. But he's living a paleolithic lifestyle in a tree house in the capital's Rock Creek Park as winter closes in, the worst on record, fifty degrees below...and for some reason the black-black world of Homeland Security has developed an interest in him.
A gripping cautionary tale of progress and its price.
