A leaked draft of a UN climate change report to be released later this month shows the planet isn't warming as quickly as previously believed, reports say.
The UN Intergovernmental Panel on Climate Change forecasts carbon emission-caused global warming would increase average temperatures by between 1.5-4.5 C, rather than the 2007 report claim of 2-4.5 C, according to a summary obtained by the National Post.
The report suggests the threshold for climate change damage may not have been crossed as most experts say that global warming of less than 2 C won't cause harm.
Author and British House of Lords member Matt Ridley, wrote in the Wall Street Journal that the latest UN study "dials back the alarm."
"It is significant because it points to the very real possibility that, over the next several generations, the overall effect of climate change will be positive for humankind and the planet," Ridley wrote.
Report co-author Myles Allen, director of Oxford University's Climate Research Network, said the report isn't a "Bible" on climate change, the Telegraph reports.
"It is not a Bible; it is a scientific review, an assessment of the literature. Frankly, both sides are seriously confused on how science works — the critics of the IPCC and the environmentalists who credit the IPCC as if it is the gospel."
The report is expected to be released Sept. 27.
