The 2011 minimum extent was about 4% lower than the 2008 minimum, yet NSIDC shows that the percentage of MYI increased by more than 15% from 2008 to 2011.
Which year had more MYI? If you passed third grade and are not a climate alarmist (or lukewarmer) you should be able to figure it out.
According to JAXA, the Arctic melt season (date max minus date min) has gotten about 30 days shorter since 2005. If the melt season ends in the next eight days, 2012 will be the shortest on record.

It is possible that this will happen, because almost all of the remaining ice is thick (1-5 metres) and temperatures in about four days are forecast to get very cold across almost the entire ice pack. More likely it will come in second shortest after 2010.

It is worth remembering back to 2008, when Mark Serreze forecast an ice-free pole – because the ice was so thin. The core of the ice pack has thickened considerably since then.
The dirty little secret about 2007 was that most of the loss of older ice occurred during the winter, not the summer. Persistent winds blew a lot of old ice out into the North Atlantic.
Since 2008, the old ice has been increasing. Last year there was an increase in two and three year old ice, so we should expect to see an increase in three and four year old ice this year.
Plausible estimates for the effect of soot on snow and ice albedos (1.5% in the Arctic and 3% in Northern Hemisphere land areas) yield a climate forcing of 0.3 Wm2 in the Northern Hemisphere. The ‘‘ef?cacy’’ of this forcing is 2, i.e., for a given forcing it is twice as effective as CO2 in altering global surface air temperature.
CO2 is the most powerful force in the Universe, and soot is twice as powerful.

Joe Romm says that Republicans are being punished by Gaia for wrecking the climate.
He would have done well in Salem in 1692, brimming with hatred and stupidity.
There is a region of low albedo, dirty ice along the western coast of Greenland. The rest of the ice sheet is very bright white.

Summer temperatures in Greenland are as low as minus 35C this week.
