Summary of the Science and Developments 2009

 

Since the dramatic loss of the Arctic Icecap it has become clearer that imminent danger does not come from the steady state predictable warming of the climate models, though this is proving bad enough. It comes from the unexpected rapid changes triggered, like the polar icecap, by circumstances that we do not understand until after they happen. These individually are called tipping points which individually or collectively may cause abrupt climate change.

 

David Bright's summary below provides an excellent basic understanding of the science. For a guide to the uncharted waters you might read Climate Code Red.pdf
