"According to the data at JAXA, as of 4/23/10, there was 4.69% more Arctic sea ice (13649531 km2) than the 2003-2009 average (13038058 km2)"   Just how far down did these folks look in the Arctic ocean, hod did they measure the thickness and quality of the ice? ... What seems to occur on the Arctic sea surface (speculated in an office from satellite ovservation) is only a small part of the whole story of how much sea ice is in the arctic and what state it is actually in...as noted from scientific research I posted a day or so ago.
