Peter Wadhams @ Cambridge: Seasonal Arctic Ice May Disappear By 2015
EDIT
With melting season still not over, concerns are growing that in a few years there will be no summer sea ice at all spelling disaster for wildlife such as polar bears, which rely on ice to hunt.
Environmentalists, who have long warned that this year would bring a record low, renewed demands for politicians and businesses to do more to cut carbon emissions. Peter Wadhams, professor of ocean physics at Cambridge University, who was branded alarmist after he first detected substantial thinning of sea ice in 1990, said: The entire ice cover is now on the point of collapse.
The extra open water already created by the retreating ice allows bigger waves to be generated by storms, which are sweeping away the surviving ice. It is truly the case that it will be all gone by 2015. The consequences are enormous and represent a huge boost to global warming.
He said that while reducing carbon emissions was the only solution, geo-engineering techniques including one proposed by a Scottish professor should be urgently explored.
