The 2007 Time Magazine book on global warming was one of the best all round features on the issues I have seen to date. We all tend to think of natural history moving at small, incremental, and glacially-slow speeds, but recent revelations suggest otherwise. This quote has stuck with me:
"Global climate systems are booby-trapped with tipping points and feedback loops, thresholds past which the slow creep of environmental decay gives way to sudden and self-perpetuating collapse." 2007 Time Magazine special edition on global warming.
