THE Intergovernmental Panel on Climate Change will warn the world's politicians that the Earth's temperature could rise far higher in response to greenhouse gas emissions than previously thought.
A secret draft version of the next report by the United Nation's influential panel of climate experts, to be given to governments in April, will say a reliable upper limit can no longer be put on how quickly the world will warm, according to the British newspaper The Guardian.
Australian scientists said the reported warning reflected a growing body of recent research showing that climate change was occurring more rapidly than expected.
Some computer models had forseen temperature increases of as much as 11 degrees from a doubling of carbon dioxide levels in the atmosphere. The climate change panel had assumed a doubling of carbon dioxide levels would lead to a temperature rise of between 1.5 degrees and 4.5 degrees.
