New climate science from down under - by Robb

Australia, once the only other developed country that made denying climate change a central government policy, has made a turnabout with a new PM. Take heart America, soon you too could join the rest of the world community to tackle this biggest of challenges.

"New Australian research showed current policies did not go far enough to manage the risks posed by climate change, according to Dr Roger Jones, a climate risk analyst with CSIRO's energy transformed flagship.

Global action was needed by 2015 to adequately reduce those risks, he said.

The research, conducted by CSIRO and Victoria University, showed even if severe emissions cuts were implemented from 2030, warming of 2.2 to 4.7 degrees could still happen by 2100.

If the present high emissions path was followed, the most likely warming was between 3.4 and 7.2 degrees."

It's not all gloom and doom however;

"Work undertaken by CSIRO showed it was very likely cuts to emissions by 2050 would pay for themselves by 2100 in economic terms."
