I also heard about this new book yesterday on NPR's Fresh Air. It sounds depressing but a must read...

The History & Future Impact of Climate Change
by Tim Flannery
Most of us suspect that climate change is happening, but is it a terrible threat to our world or an exaggerated beat up? Or is it something in between - an issue that humanity must eventually face, but not yet?
In this groundbreaking and essential new book, Tim Flannery argues passionately for the urgent need to address - NOW - the implications of a global climate change that is damaging all life on earth and endangering our very survival.
This book is unimpeachable in its authority, deftly and accessibly written in its vision for what each of us can do to avoid catastrophe. It is a global call to arms, laying out plainly if not controversially what we know, what we think might happen, and what tools we have available to us to make a difference. The Weather Makers will change your life.
It is a difficult subject and hard for people to evaluate dispassionately because it entails deep political and industrial implications, and because it arises from the very core processes of our civilisation's success. Right now our fate is in our hands, for we are the weather makers, and we already possess the tools required to avoid catastrophic climate change.
