Quotes from Ross Garnaut

The best that we can hope for now is holding increases globally to around 1.75°C. This could be achieved if the world moves decisively towards zero net emissions by 2050. But temperatures over land will increase by more than the average over land and sea. An increase of 1.75°C for the whole world would mean more than 2°C for Australia – twice the increase that this year helped to bring bushfires in August to New South Wales and Queensland.

There is a chasm between a world that quickly breaks the link between modern economic growth and carbon emissions, and a world that fails to do so. The side of the chasm we are now on is a dangerous place. It would be reckless beyond the normal human irrationality for us to stay where we are.
