Climate change - so what?

An interesting collection of papers has recently been published in Proceedings of the Royal Society A (London) answering the questions of will the world get over 4 degrees C warmer and so what if it does... 

Four degrees and beyond: the potential for a global temperature increase of four degrees and its implications

It is based around papers given at a conference in 2009 that asked '(i) how probable a warming of four degrees or higher might be, (ii) what the consequences of such a warming might be for ecosystems and society, (iii) how to adapt to such large changes, and (iv) how to keep the risk of high-end climate change as low as possible.'

Here are some views from a group of Aussie climate scientists!
