evidence: The studies that this article points to make no such claim. This research characterizes the varying temperature conditions at the base of glaciers that cause them to either freeze to the ground or sit on thawed ground. This has important implications for understanding how different portions of the ice sheet will respond to global warming, but it does not explain the glacial ice loss measured over the last century. [...] This article at Climate Change Dispatch points to two studies published on geothermal heat flow beneath ice sheets to support its claim: one on the Greenland Ice Sheet1 and one on a portion of Antarctica2. However, neither study makes or supports the claim that geothermal heat—rather than human-caused global warming—is the driver of glacial ice loss. The Climate Change Dispatch article was published in August 2018, but has continued to spread across social media and reappear through posts on other websites, leading to more than 40,000 shares on Facebook at the time of this review. [...] Like the Greenland study, the Antarctica study said nothing about a potential link between increasing heat flow in the Earth’s crust and recent ice loss. Instead, it describes a geologic condition that has likely existed for tens of millions of years and focuses on informing projections of future ice loss due to global warming. "[B]asal conditions are of major importance to the proper formulation of numerical simulations of ice sheet evolution in a warming climate," the authors wrote.
