It has been a busy few weeks. All sorts of things have become apparent: Climate change is real, and it man-made, Australia’s policies are a joke, renewable energy investment is leaving Australia, wind and solar do not add costs to the grid, they don’t need new back-up, and they have been reducing prices. And the world is changing while Australia stands still. So, what’s the problem? Clarke and Dawe have the answer.

The latest survey compiled by the CSIRO and the Bureau of Meteorology – two institutions that the Abbott government has yet to remove or successfully muzzle – shows that Australia is almost a degree warmer, on average, than it was a century ago. And that is roughly in line with global rates of atmospheric warming. And, it is set to continue warming at a rate that depends on how fast greenhouse emissions can be reduced.
The report says seven of Australia’s 10 warmest years have happened since 1998; over the past 15 years, very warm months have occurred at five times the long-term average, while very cool months have declined by a third; and by 2070, temperatures will be anywhere between 1C and 5C warmer than the 1980-1999 average, depending on future emissions cuts. Note the link between rising temperatures and emissions.
