Climate warming 'highly unusual' says new study http://apocadocs.com/s.pl?1232311836
A major U.S. government report on Arctic climate, prepared with information from eight Canadian scientists, has concluded that the recent rapid warming of polar temperatures and shrinking of multi-year Arctic sea ice are "highly unusual compared to events from previous thousands of years."
The findings, released Friday, counter suggestions from skeptics that such recent events as the opening of the Northwest Passage and collapse of ice shelves in the Canadian Arctic are predictable phenomena that can be explained as part of a natural climate cycle rather than being driven by elevated carbon emissions from human activity.
A summary of the report -- described as "the first comprehensive analysis of the real data we have on past climate conditions in the Arctic," by U.S. Geological Survey director Mark Myers -- warns that "sustained warming of at least a few degrees" is probably enough "to cause the nearly complete, eventual disappearance of the Greenland ice sheet, which would raise sea level by several metres."

The CO2 emissions from skeptics straining to explain away global warming just went up a couple ppm.
