Today a 64-page "Copenhagen Diagnosis" was released by a group of climate scientists from several nations. They say now it looks like the average global temps couldclimb more than ten degrees Fahrenheit this century. Sea levels could increase more than three feet.
This report concludes that CO2 levels in the atmosphere are near the top of what the IPCC thought was possible when they issued their most recent report in 2007. The group says work on reducing man-caused greenhouse gasemissions must begin now.
"Our available emissions to ensure a reasonably secure climate future are just about used up," said Matthew England, co-director of the Climate Change Research Centre of the University of New South Wales in Australia.
The 26 scientists from eight countries also say the polar ice caps are melting faster than expected. That the need for international action is "urgent."
The group urges international action at the Copenhagen talks that begin December 7.
