Should we now be talking about the Arctic “death spiral”?
Northern Hemisphere sea ice extent in December 2010 was the lowest in the 31-year satellite record, according to the National Snow and Ice Data Center. Ice volume in December was also the lowest on record for this time of year, according to University of Washington Polar Ice Center.
2010 saw the third lowest extent of sea ice:
Despite a late date of the maximum in winter sea ice extent, the minimum sea ice extent for September 2010 was third lowest in the 1979 to 2010 satellite record, above only 2007 (the record low) and 2008. The late summer of 2010 saw an open Northwest Passage: this year, the deep water channel (the northern route) from M’Clure Strait to Lancaster Sound was navigable. The Northern Sea Route along the Siberian coast also became briefly navigable.
Perhaps we should be concerned that Hudson bay did not completely freeze over for the time in recorded history:
At the end of December, the eastern portion of Canada’s Hudson Bay remained unfrozen, the first time in recorded history that Hudson Bay has not been completely frozen over at the end of the year. The unusual amount of open water led to temperatures that averaged 20°C (36°F) above normal over a region larger than Texas during the first ten days of January.
Quick deniers, assume panic stations!
Claim these are isolated events!
Make sure you soothe your mounting anxiety by focussing on a few irrelevant facts!
Post some links to WUWT!
Read some pseudoscience peddled by “Lord” Monckton!
All the scientists are lying!
Every scientific measuring device on the planet is broken or wrong!
Make global warming go away!
Sit in a corner and tell yourself over, and over: “There is no global warming, there is no global warming…”
The more you say it, the more it can’t be true!
