Death spiral: Arctic ice loss 50% higher than predicted

Via the Guardian:

Sea ice in the Arctic is disappearing at a far greater rate than previously expected, according to data from the first purpose-built satellite launched to study the thickness of the Earth’s polar caps. 

Preliminary results from the European Space Agency’s CryoSat-2 probe indicate that 900 cubic kilometres of summer sea ice has disappeared from the Arctic ocean over the past year. 

This rate of loss is 50% higher than most scenarios outlined by polar scientists and suggests that global warming, triggered by rising greenhouse gas emissions, is beginning to have a major impact on the region. In a few years the Arctic ocean could be free of ice in summer, triggering a rush to exploit its fish stocks, oil, minerals and sea routes. 

Using instruments on earlier satellites, scientists could see that the area covered by summer sea ice in the Arctic has been dwindling rapidly. But the new measurements indicate that this ice has been thinning dramatically at the same time. For example, in regions north of Canada and Greenland, where ice thickness regularly stayed at around five to six metres in summer a decade ago, levels have dropped to one to three metres.

So, is the European Space Agency part of “the conspiracy” as well? I’m sure they’re just faking the data to get funding. How else are they going get their greedy hands on more satellites…

    It’s strange you know – Andrew Bolt often posts graphs of sea ice extent on his blog, but I’m not sure he’s posted this one. Odd.
