…4 degrees is pretty much about the centre figure that is being projected by IPCC …that doesn’t mean that that’s when warming stops. Warming would continue to occur for some time, for some centuries after that…populations will move to try and find food….and projections go from 65 to 250 million migrating people by the end of century…clearly some form of adaptation, but not life as we understand it…looking at days over 35 degrees, places like Darwin, would move from 11 days to 308… projections are, that while Alice Springs would resemble the Sudan, Darwin will resemble like no place on earth…much more substantial target, around 35-40, even 45 per cent below 2000 levels by 2020…in 10 or 20 years time we’ll start to panic and start to really begin to move very, very quickly to reduce emissions. But much more expensive, less effective set of policies…Melbourne University’s Dr Peter Christoff. He’s the editor of that report; Four Degrees of Global Warming: Australia in a Hot World.
