Antarctica’s second largest ice shelf could shrink dramatically

IMG_0287.JPGBefore the end of the century, rising temperatures could trigger an influx of warm water beneath Antarctica’s second-largest ice shelf – and once it begins, researchers say there’s ‘no going back.’ The phenomenon would cause the ice to lose contact with the seafloor, which has so far acted as a natural brake to slow the ice flow. Scientists say they’ve already detected the first signs of the process, and once underway, it will cause the ice to shed at a much faster rate, dramatically  New simulations reveal that rising air temperatures over the Weddell Sea could make for less sea ice, triggering processes that permanently do away with the cold water barrier (illustrated). Once underway, the process will cause the ice to shed at a much faster rate…..Read More
