Usually ignored by climate alarmists, geothermal heat in Antarctica has long been known to increase ice melt. Now the peer-reviewed research is confirming the case. Thwaites glacier: Significant geothermal heat beneath the ice stream Charles Rotter Researchers map the geothermal heat flow in West Antarctica; a new potential weak spot in the ice sheet’s stability is identified Peer-Reviewed Publication ALFRED WEGENER INSTITUTE, HELMHOLTZ CENTRE FOR POLAR AND MARINE RESEARCH IMAGE: GEOPHYSICAL MEASUREMENTS WITH A MAGNETOMETER BEING TOWED WITH RV POLARSTERN’S BOARD HELICOPTER. view more CREDIT: ALFRED-WEGENER-INSTITUT / THOMAS RONGE Ice losses from Thwaites Glacier in West Antarctica are currently responsible for roughly four percent of the global sea-level rise. This figure could increase, since virtually no another ice stream in the Antarctic is changing as dramatically as the massive Thwaites Glacier. Until recently, experts attributed these changes to climate change and the fact that the glacier rests on the seafloor in many places, and as such comes into contact with warm water masses. But there is also a third, and until now one of the most difficult to constrain, influencing factors. In a new study, German and British researchers have shown that there is a conspicuously large amount of heat from Earth’s interior beneath the ice, which has likely affected the sliding behaviour of the ice masses for millions of years. This substantial geothermal heat flow, in turn, are due to the fact that the glacier lies in a tectonic trench, where the Earth’s crust is significantly thinner than it is e.g. in neighbouring East Antarctica. The new study was published today in the Nature online journal Communications Earth & Environment. . . . .
The question can now be considered closed. Until Recently Scientists Believed Climate Change Has Been Melting Antarctic Glaciers. Now They Do Not. By Kenneth Richard on 6. September 2021 Share this... According to a new study, 36% of 1979-2017 Antarctic ice loss was from the Thwaites and Pine Island glaciers. Scientists believed this glacier melt was due to anthropogenic climate change “until recently”. Now they say the glacier mass losses are due to the thin underlying crust and anomalously high geothermal heat in this region. . . .
A chunk of the alarmist narrative can now be set aside. Scientists now blame geothermal heat for melting Antarctic glaciers [link]
Warmist/alarmists ignore these long known revelations since they are too deep into the AGW pseudoscience paradigm to catch up with the science research. Watch them ignore this full access published paper, they have to, to maintain their delusion that it is the mighty CO2 monster lurking under the ice melting the glaciers from below.
