Scientists: Greenland's Superthaw Due to Superhot Magma not Global Warming

According to scientists the Greenland ice shelves may not be melting from global warming but from the recent discovery of super hot magma beneath a thin layer of the Earth's crust.
In recent years, Greenland’s ice has been melting more and flowing faster into the sea—a record amount of ice melted from the frozen mass this summer, according to recently released data—and Earth’s rising temperatures are suspected tobe the main culprit.

But clues to a new natural contribution to the melt arose when scientists discovered a thin spot in the Earth’s crust under the northeast corner of the Greenland IceSheet where heat from Earth’s insides could seep through, scientists will report here this week at a meeting of the American Geophysical Union.

“The behavior of the great ice sheets is an important barometer of global climate change,” said lead scientist Ralph von Frese of Ohio State University. “However, to effectively separate and quantify human impacts on climate change, we must understand the natural impacts too.” [1]
Apparently this "hotspot" of hot magma sitting just beneath the northeast corner of Greenland is responsible for the record amount of ice melted. This is contrary to the "popular" Global Warming dogma where man and his "excesses" are the culprit.

Hotspots are responsible for more than just melting ice sheets.
Hawaii was created by a “hotspot” beneath the ocean floor. Hotspots form in areas where superheated magma in the Earth’s mantle breaks through the Earth’s crust. Over the course of millions of years, the Pacific Tectonic Plate has slowly moved over this hotspot to form the entire Hawaiian Island archipelago. [2]
Lead scientist Ralph von Frese:
“It could be that there’s a volcano down there,” he [lead scientist Ralph von Frese] said, “but we think it’s probably just the way the heat is being distributed by the rock topography at the base of the ice." [1]

A recent study found that there was a similar Greenland ice melt documented in the 1920's.
Professor Jason Box and undergraduate Adam Herrington, co-authors of the study, said their finding reinforces the belief that glaciers and other bodies of ice are exquisitely hyper-sensitive to climate change and bolsters the concern that rising temperatures will speed the demise of that island's ice fields, hastening sea level rise.They said their research might help discount criticism that the melting of Greenland 's glaciers is merely an isolated, regional event. [2]

No mention of the effects of the superthin mantle, hot magma or possibility of a volcano under Greenland's ice sheets just the "hand wringing" Global Warmist Alarmists.

Scientists studying the earth's core discovered that our Earth is the ultimate recycler of itself.
A huge slab of folded Earth that scientists think used to be part of the ocean floor has been detected near the planet's core.

The discovery supports the theory that Earth's crust is constantly recycled deep into the planet as molten material from below simultaneously pushes up to refresh the surface.

The structure is about 125 miles deep and at least 125 miles wide and 370 miles in the north-south direction. In consistency, it is more like a giant, folding mush of taffy, researchers said today. [3]
This recent discovery along with the one where it was determined mixing a thin crust with superhot magma makes ice melt faster is quite astounding in its simplicity. Both discoveries demonstrate that there is more to learn about this fascinating planet we live on.

That the "It's Global Warming, Stupid," crowd's frozen facts might be undergoing a little super magma melt of their own.
