A new NASA study published in the Journal of Glaciology shows snow in Antarctica began a long-term accumulation 10,000 years ago and is adding much more ice to the continent each year than it is losing as some glaciers melt. The thinning of some glaciers has been shown to be due largely to geologic (volcanic) activity below the ice mass. According to NASA’s analysis, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001, slowing to 82 billion tons of ice per year between 2003 and 2008.
Jay Zwally, a glaciologist with NASA Goddard Space Flight Center, the lead author of the study, stated, “The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away.” The persistent ice mass accumulation in Antarctica confounds climate model predictions. As NASA’s analysis shows, the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which said Antarctica was overall losing land ice, is just dead wrong. Both on land and at sea, ice growth continues.
