Earthís Internal Heat Driving Greenlandís Ice Melt, Scientists Discover

I know eh...but anyway..more info for the ignorant:

Greenland sits over an area of abnormally hot mantle material that drives a widespread melting beneath the ice sheet and rapid ice flow over a distance of several hundred kilometres, a new study has found.



Greenlandís lithosphere has hot depths which originate in its distant geological past and cause the islandís ice to rapidly flow and melt from below.

An anomaly zone crosses Greenland from west to east where present-day flow of heat from the Earthís interior is elevated.

With this anomaly, researchers from GFZ German Research Centre for Geosciences (GFZ) could explain observations from radar and ice core drilling data that indicate a widespread melting beneath the ice sheet and increased sliding at the base of the ice that drives the rapid ice flow over a distance of 750 kilometres from the summit area of the Greenland ice sheet to the North Atlantic Ocean.

The globull warming truthers must be having conniptions lately. All their lies are being exposed.

Wouldn't that mean you would have one of the better inside stories?
That 'hot spot' might lead all the way back to Iceland and a warmer part of the mantle is migrating westward and the whole ocean floor is warming up and Greenland is above the water line so the heating is visible. The lakes that form would also be from that heat rather than the sun so fall will come later and spring will arrive earlier overall.

What comes up must go down and when that westward flow meets the eastward flow from the Pacific Rift it will go up or go down, in our case the line between Hudson Bay and the GOM would be above the down-flow and that comes with a suction effect on the upper crust which we see as sinkholes

I wonder how long it will be before the Arizona impact crater will be reclassified as a sinkhole as well as all of the lakes on the northern parts of Canada which will at some point resemble the African Rift?

It was 71F in New York City on Thursday. Nothing particularly notable in that.

It was 74F in Nuuk on Thursday, something that's very notable.

Nuuk is the capital of Greenland (link is external) and 74F (23.2C) is the highest June temperature ever recorded in that Arctic country. Highest, warmest, hottest - call it what you like.

Thursdayís toasty reading in Nuuk marks the second exceptionally warm temperature recorded in southwest Greenland since April, when the ice melt season began about a month prematurely.

Ever recorded doesn't mean "ever". Obviously there were some pleasant temps there at least 1100 years ago, considering the place was pretty much ice-free for the following 300-400 years.

Nuuk is getting 4 more hours of sunlight a day than New York.

Any questions?
