Maybe It's Not Global Warming: Volcanic Heat Found Under Antarctica's Fastest Melting Glacier | The Daily Sheeple:
"A group of scientists at the University of Rhode Island stumbled on something unexpected when analyzing data brought back from a 2014 expedition to western Antarctica.
Scientists found an abundance of the noble gas Helium-3, indicating there is a volcanic heat source beneath the Pine Island glacier — the fastest-melting glacier in the South Pole. 
The findings were published in a study in the journal Nature Communications.
...“When you find helium-3, it’s like a fingerprint for volcanism. 
“The volcan
ic heat sources were found beneath the fastest moving and the fastest melting glacier in Antarctica, the Pine Island Glacier,” Loose said.
“It is losing mass the fastest.”
Previous research has identified a network of volcanic rifts beneath Western Antarctica that could be contributing to the ice sheet’s instability.
A 2014 University of Texas study 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.”...
