Is global warming going to cause the West Antarctic Ice Sheet to slide off into the ocean? While many fear this scenario, a recent study by scientists from Pennsylvania State University and the University of Texas seems to put these fears on ice. Published in the journal Science, these researchers found that a sedimentary wedge of rock and sediment tends to keep the ice sheet intact, and by doing so it allows ice to build up on the glacier and keep its grounding line in place. What this all means is that sea level rises of a few meters, such as those projected by many global warming advocates, are unlikely to affect ice sheet behavior, and so the prospects of the West Antarctic ice sheet slipping off into the ocean are slim indeed.
