Scientists have been warning the world about global warming for almost three decades. But the rest of us are only now starting to get the message. The planet is warming at an unusually rapid rate, and this warming is largely being caused by human activity. Shrinking glaciers, thawing permafrost, erratic weather and threatened freshwater supplies are already affecting the lives of people around the globe, and the worst is yet to come. The crisis is real, but there is little consensus about how to confront the problem, not only because the science is complex, but because the economic, political and social implications of taking action are vast, far-reaching and unsettling. And despite the urgency, climate change deniers seem to be more vocal than ever. This revised and updated edition includes the most recent scientific findings while addressing the main issues. What is happening, and how did we get here? What is the basic science behind climate change? What is going to happen in the future? And, most important, why is it so hard for us to accept what is going on, and what can we do about it? Charts, maps, a glossary, an index and suggestions for further reading accompany the text
