Many of the scientific studies published in the past two years on the stability of the Antarctic ice sheet can best be characterized as anxiety-inducing, if not outright panic-causing

Studies have shown that huge chunks of the continent may be far more unstable than previously thought, and more susceptible to melting from manmade climate change and other factors. This is especially the case with the West Antarctic Ice Sheet and the glaciers along the Antarctic Peninsula
