His latest report sets out much lower targets than initially proposed and says that they shouldn't rise unless the rest of the world also introduces an emissions trading scheme.
Naturally, Australia's leading Climate Alarmists who have their noses firmly in the public trough have become apoplectic at the prospect that Australia would not choose to reduce its standard of living and international competitiveness.
Leading Australian climate scientists have urged the federal government to ignore adviser Ross Garnaut and act more aggressively to counter climate change.If you've ever seen David Karoly talk on the subject of climate change then you'll know what a zealot looks like.
Fairfax newspapers said three Australian authors with the UN's Intergovernmental Panel on Climate Change - Bill Hare, David Karoly and Amanda Lynch - say Professor Garnaut's advice would all but guarantee environmental and social disaster.
In his latest report, released last week, Prof Garnaut recommended Australia cut its emissions by 10 per cent by 2020.
But speaking separately to Fairfax, the three authors described Prof Garnaut's recommendations as inconsistent, disappointing and wrong.
All three argued for a 25 to 40 per cent cut, saying Australia was likely to be the developed nation worst hit by climate change.
Dr Hare, based at Germany's Potsdam Institute for Climate Impact Research, said adopting Professor Garnaut's recommendation would trigger big sea level rises, devastate ecosystems and dry up water supplies in Asia.
"Ross Garnaut's report is effectively putting off the cost of climate change to another generation, who will have to deal with a 3-degree rise in temperature as well as sucking carbon dioxide out of the air," he said.
"It has failed to face up to this risk issue. As a highly vulnerable country, I would have thought it would have been better for Australia to be going forward with a more aggressive position."
Professor Lynch, a federation fellow at Monash University, said the report would confirm other nations' perceptions that Australia would not match its rhetoric with action.
"I think they will take it as another piece of evidence that Australia is not really interested in walking the walk," she said.
Professor Karoly, a federation fellow at the University of Melbourne, said if Australia adopted Prof Garnaut's position, it would abandon all claims to leading the climate change debate.
Prof Garnaut's final report is due at the end of this month.
His performance on the ABC's post-Great Global Warming Swindle panel was risible but host Tony Jones kept deferring to him to answer questions related to the science. Instead of offering direct, clear answers Karoly babbled on like Barack Obama without a teleprompter.
The wheels are slowly falling off the scam that is climate science but there's a little way to go before we're safe, as the mainstream media is still in the pocket of Big Green in spite of a few instances of blasphemy recently.
Another five years or so of cooling temperatures should be enough to kill the insanity.
