Transient Greenland warming excites Warmists

Yep! FOUR WHOLE DAYS days that were warmer than anything else in 30 years. They tell us that 10 years is too short a period upon which to base generalizations but for them just 4 days is enough! Anthony Watts has a more detailed assault on this latest bit of malarkey

The Greenland ice sheet is melting at an "unprecedented" rate, according to NASA satellite data that shows 97 per cent of the vast mass is undergoing some form of melting.

"This was so extraordinary that at first I questioned the result: Was this real or was it due to a data error?" a NASA researcher, Son Nghiem, said.

About half of the ice sheet usually shows signs of melting in a northern hemisphere summer, but the satellite data shows that between July 8 and July 12 the melt extended to cover almost all of Greenland.

It follows the breaking off this month of a giant chunk of ice from Greenland's Petermann Glacier. This formed an iceberg about twice the size of Manhattan, about 120 square kilometres in area.

"For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations," NASA researchers said in a statement.

"Nearly the entire ice cover of Greenland, from its thin, low-lying coastal edges to its two-mile [3.2-kilometre] thick centre, experienced some degree of melting at its surface, according to measurements from three independent satellites analysed by NASA and university scientists."

They described the event as being without precedent, because such a massive loss of ice has not been observed by humans, although estimates derived from studying old, compressed ice suggest that melts on this scale happen about once every 150 years....

The NASA statement said the huge melt had been driven by an unusual "heat dome" of relatively warm air that travelled across Greenland this month. The warm patch spiked just before July 18, and has now dissipated, they said.
