The Sixth Extinction

Drop everything and read The Sixth Extinction by Elizabeth Kolbert.  She is a writer for the New Yorker magazine and writes about science superbly well.

Unless we eliminate CO2 emissions now the oceans are going to die in less than 200 years.  When the oceans die, almost all multicellular organisms are going to die with it: the air won't be breathable. The situation will be similar to the greatest extinction of all, the Great Dying at the boundary between the Permian and Triassic periods, which not coincidentally is the boundary between the Paleozoic and Mesozoic eras.

In fact, the "debate" about global climate change is a sideshow: if we continue to follow the business as usual scenario the world as we know it will cease to exist in just a few generations. 

There is no longer any room for climate deniers in politics.   There is no longer any time for inaction. The world must act now.
