Arctic Report Card

November 25, 2010

Just a quick follow up on arctic ice.
Prevailing science opinion among informed observers is best represented by the recently released Arctic Report Card, an annual update from the National Oceanic and Atmospheric Administration. The report is based on scientific reports from 69 scientists in eight countries.

Key Points: Region Continues to Warm at Unprecedented Rate
• Greenland is experiencing record-setting high temperatures, ice melt and glacier area loss;
• Summer sea ice continues to decline — the 2009-2010 summer sea ice cover extent was the third lowest since satellite monitoring began in 1979, and sea ice thickness continues to thin. The 2010 minimum is the third lowest recorded since 1979, surpassed only by 2008 and the record low of 2007; and
• Arctic snow cover duration was at a record minimum since record-keeping began in 1966.
• The Arctic is unlikely to return to its former state

According to a McClatchey report, “Jackie Richter-Menge, the chief editor of the report and a research civil engineer at the Cold Regions Research and Engineering Laboratory in Hanover, N.H., said the warming trend made any return to previous Arctic conditions increasingly unlikely, at least in the foreseeable future.”

“It’s very likely Arctic climate warming will continue and that we’ll continue to set records in the years to come,” she said.
