Arctic Sea Ice Death Spiral

 

Arctic Death Spiral Bombshell: CryoSat-2 Confirms Sea Ice Volume Has Collapsed

[Excerpted] The sharp drop in Arctic sea ice area has been matched by a harder-to-see, but equally sharp, drop in sea ice thickness. The combined result has been a collapse in total sea ice volume — to one fifth of its level in 1980.

Back in September, Climate Progress reported that the European Space Agency’s CryoSat-2 probe appeared to support the key conclusion of the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the University of Washington’s Polar Science Center: Arctic sea ice volume has been collapsing much faster than sea ice area (or extent) because the ice has been getting thinner and thinner.

Now the Natural Environment Research Council (NERC), the UK’s primary agency for funding and managing environmental sciences research, has made it official....

...“While two years of CryoSat-2 data aren’t indicative of a long-term change, the lower ice thickness and volume in February and March 2012, compared with same period in 2011, may have contributed to the record minimum ice extent during the 2012 autumn,” says Professor Christian Haas of York University, Canada Research Chair for Arctic Sea Ice Geophysics, co-author of the study and coordinator of the international CryoSat sea ice validation activities.

Majia here: The sharp drop off - RECORD MINIMUM ICE - recorded during the Fall of 2012 may possibly have been exacerbated by Fukushima radiation.
