UXBRIDGE, Canada, Sep 20, 2010 (IPS)
The carbon dioxide emissions from burning fossil fuels have melted the Arctic sea ice to its lowest volume since before the rise of human civilisation, dangerously upsetting the energy balance of the entire planet, climate scientists are reporting.
“The Arctic sea ice has reached its four lowest summer extents (area covered) in the last four years,” said Mark Serreze, director of the National Snow and Ice Data Center in the U.S. city of Boulder, Colorado.
The volume – extent and thickness – of ice left in the Arctic likely reached the lowest ever level this month, Serreze told IPS.
“I stand by my previous statements that the Arctic summer sea ice cover is in a death spiral. It’s not going to recover,” he said.
