I find this very disturbing that so much of the surface of Greenland's ice sheet has melted. Scientist say this is unprecedented and are alarmed by it, they thought it was a mistake at first.The Greenland ice sheet melted at a faster rate this month than at any other time in recorded history, with virtually the entire ice sheet showing signs of thaw.
The rapid melting over just four days was captured by three satellites. It has stunned and alarmed scientists, and deepened fears about the pace and future consequences of climate change.
NASA warns 97 percent of Greenland ice sheet surface melted in four days
