NASA Has More Evidence Volcanic Activity Is Heating Up Antarctica’s Ice Sheet
A 2014 University of Texas study found western Antarctica was a literal hotbed for geothermal heat. Researchers concluded that “large areas at the base of Thwaites Glacier are actively melting in response to geothermal flux consistent with rift-associated magma migration and volcanism.”
The following year, another team of U.S. scientists found there’s a huge amount of geothermal heat under western Antarctica. “The high geothermal heat flux may help to explain why ice streams and subglacial lakes are so abundant and dynamic in this region,” the study found.
Earlier this year, Scottish researchers found 91 previously unidentified volcanoes under the Antarctic ice sheet, including one that’s some 13,000 feet tall.
