Anthropogenic Global Warming? No, says new study: volcanoes

Study: West Antarctic Glacier Melt Due To Volcanoes, Not Global Warming

by Michael Bastach

A new study by researchers at the University of Texas, Austin found that the West Antarctic Ice Sheet is collapsing due to geothermal heat, not man-made global warming.

Researchers from the UTA’s Institute for Geophysics found that the Thwaites Glacier in western Antarctica is being eroded by the ocean as well as geothermal heat from magma and subaerial volcanoes. Thwaites is considered a key glacier for understanding future sea level rise.

UTA researchers used radar techniques to map water flows under ice sheets and estimate the rate of ice melt in the glacier. As it turns out, geothermal heat from magma and volcanoes under the glacier is much hotter and covers a much wider area than was previously thought.

“Geothermal flux is one of the most dynamically critical ice sheet boundary conditions but is extremely difficult to constrain at the scale required to understand and predict the behavior of rapidly changing glaciers,” UTA researchers wrote in their study, which was published in the Proceedings of the National Academy of Sciences.

The geothermal heat under the glaciers is likely a key factor in why the ice sheet is currently collapsing. Before this study, it was assumed that heat flow under the glacier was evenly distributed throughout, but UTA’s study shows this is not the case. Heat levels under the glacier are uneven, with some areas being much hotter than others.

At the same time:

But reports of the western ice sheet’s collapse comes as Antarctic ice sheets continue to break records. At the end of May, Antarctic sea ice extent reached the highest level since measurements began in 1979.

Sea ice extent reached nearly 13 million square kilometers — 10.3 percent above the 1981-2010 climatological average of 11.7 million square kilometers. The previous record was 12.7 million square kilometers set in 2010.

Warming and cooling?  Yes, the earth does both.  Caused solely by man, anthropogenic,  and irrevocably unrecoverable?  No.  Do the Religious Left believe “global warming” is unrecoverable, fervently, with all their hearts?  Yes, they do.  But I submit: in the extremely brief time we have been documenting the earth’s climate, we no more have a grasp of earth’s changing face than we do the depth and breadth of space.

I also submit: over-reacting to so-called “global warming” is a wonderful way to break nations, pit people against each other, fleece the pockets of the American Taxpayer and redistribute wealth as determined by DC in concert with the Religious Left.
