If you think that global warming means slightly hotter weather and a modest rise in sea levels that will persist only so long as fossil fuels hold out (or until we decide to stop burning them), think again. In The Long Thaw, David Archer, one of the world's leading climatologists, predicts that if we continue to emit carbon dioxide we may eventually cancel the next ice age and raise the oceans by 50 meters. The great ice sheets in Antarctica and Greenland may take more than a century to melt, and the overall change in sea level will be one hundred times what is forecast for 2100. By comparing the global warming projection for the next century to natural climate changes of the distant past, and then looking into the future far beyond the usual scientific and political horizon of the year 2100, Archer reveals the hard truths of the long-term climate forecast.
Archer shows how just a few centuries of fossil-fuel use will cause not only a climate storm that will last a few hundred years, but dramatic climate changes that will last thousands. Carbon dioxide emitted today will be a problem for millennia. For the first time, humans have become major players in shaping the long-term climate. In fact, a planetwide thaw driven by humans has already begun. But despite the seriousness of the situation, Archer argues that it is still not too late to avert dangerous climate change--if humans can find a way to cooperate as never before.
Revealing why carbon dioxide may be an even worse gamble in the long run than in the short, this compelling and critically important book brings the best long-term climate science to a general audience for the first time.

"Worried about warming but confused about carbon? Try [The Long Thaw], which tells you nearly everything you need to know with down-to-earth clarity and brevity."--Evan Hadingham, PBS's NOVA blog
"Archer . . . presents the dire and long-lasting consequences of our fossil-fuel dependency but concludes that it's not too late for us to go a different, better way."--Avital Binshtock, Sierra Club Blog
"A beautifully written primer on why climate change matters hugely for our future--on all time scales."--New Scientist
"Archer has perfectly pitched answers to the most basic questions about global warming while providing a sound basis for understanding the complex issues frequently misrepresented by global warming skeptics. With a breezy, conversational style, he breaks complex concepts into everyday analogies. Divided into three parts--the Present, the Past and the Future--Archer provides a complete picture of climate change now, in the past, and what we can expect in years and centuries to come. His models, though conservative, imply that humans won't survive the environmental consequences of severe warming over the next thousand years. While Archer is neither grim nor pessimistic, he is forthright about what's at stake, and what must do to avert catastrophe."--Publishers Weekly
"It is comprehensive, well written and includes numerous useful vignettes from climate history. Archer leads the reader to a simple yet accurate picture of climate changes, ranging from geological time scales to current warming, ice ages and prospects for the future."--Susan Solomon, Nature
