THE United Nation's latest investigation into climate change reportedly admits the world has been warming at only just over half the rate it had claimed in 2007.
According to the UK's Daily Mail newspaper, a leaked draft of the UN's Intergovernmental Panel on Climate Change's (IPCC) latest assessment of the state of the climate and global warming - AR5 - says the earth has been warming at a rate of 0.12C each decade since 1951.
But it says the last major IPCC report, released in 2007 and called AR4, claimed the planet was warming at a rate of 0.2C every decade.
Australian scientists who have questioned the way the IPCC assessments predict the rate of climate change and the impact of man-made pollution on the earth's warming, said on Monday the leaked report confirmed forecasts of imminent doom were drastically wrong.
Key Labor climate change figures including shadow minister Mark Butler, former Prime Minister Kevin Rudd, and former Climate Change Minister Penny Wong on Monday ducked questions about how much they relied on IPCC science in introducing their climate policies including the carbon tax.
Incoming Climate Action Minister Greg Huntdeclined to comment, saying he would wait until the final version of the AR5 assessment report was released on September 27.
But Liberal Senator Cory Bernardi called for Labor and the Greens to stop pushing the IPCC's "propaganda" to the public.
