By the way, in describing “Record Levels of Arctic Sea Ice”, I borrowed a “trick” from the (ever dishonest) alarmists. The “record” applies only to this particular date and only to the date range covered by this particular source. The (ever dishonest) alarmists, of course, never offer a similar disclosure when describing their alleged “records”.

May (month end averages) NSIDC (sea ice extent)
1981 Northern Hemisphere = 13.9 million sq km
2007 Northern Hemisphere = 12.9 million sq km
2009 Northern Hemisphere = 13.4 million sq km
2010 Northern Hemisphere = 14.7 million sq km
1979-2000 Northern Hemisphere May. mean = 13.6 million sq km
Averages carry the best info. Here is my full report:

I see, all has been well, with you. GK
SBVOR: A translocation error occurred in my report. May 2010 ice extent should read 13.1 million km2 NOT 14.7 million km2. Please correct and I apologize for the error. Hope I didn't cause any undue excitement. GK
G. Karst,
Thanks for the data.
