NSIDC told us on March 23 “Annual maximum ice extent reached” and “This year’s maximum tied for the lowest in the satellite record.”
In fact it is the latest maximum on record (indicating a cold spring) and ice extent is higher than 2005 and 2006 – the two years with the highest summer minimums in the DMI record.
Mark Serreze at NSIDC wrote in 2008 :
“As the climate warms, the summer melt season lengthens …”
Last year was the shortest melt season on record.
Looks like 2011 might be even shorter.
