The Arizona Republic re-posting an AP article by Seth Bornstein July 25, 2012, p. A14
"Experts can't say if climate change is cause"
"Nearly all of of Greenland's massive ice sheet suddenly started melting a bit this month, a freak event that surprised scientists"
...The ice melt area expanded from 40 percent of the ice sheet to 97 percent in four days, according to NASA..."
Majia here: The article states that this has happened before but scientists cannot determine whether the cause is a "natural rare event or on triggered by man-made global warming."
I'm betting on the latter explanation.
It is possible this ice melt is being caused by a high-pressure zone produced by Fukushima radiation
