Temperatures on the West Antarctic Ice Sheet can plummet below –50 degrees Celsius in winter. But under the ice, scientists have found intense geothermal heat seeping up from Earth’s interior. The heat production that they measured is nearly four times the global average. Andrew Fisher, a hydrogeologist at the University of California, Santa Cruz, says it is “higher than 99 percent of all the measurements made on continents around the world." According to results reported July 10 in Science Advances, this excessive heat could melt up to 35 cubic kilometers of water off the bottom of the West Antarctic Ice sheet each year.
