Beyond three degrees
In response to David Spratt's legitimate scepticism about Australia’s climate policy, there is really only one point to make. The world will not spend very long at 3°C of warming because by then it will be heading rapidly for 4 or 6 or higher. Many components of the climate system will have tipped and be reinforcing warming. The runaway will be far beyond humans to control. A policy for 3 degrees is a policy for apocalypse.
