As per the new study, almost half of the West Antarctic Ice sheet is now visible because of the rising temperature and the melting ice of the glaciers. The layer has become almost around 122 meters thin according to the scientists at the University of Leeds in England. The thinning of ice has increased on a large scale since 1992 as the spreading has increased by 24% of West Antarctica. The largest ice streams in the region the Pine Island and Thwaites glaciers are losing ice five times faster than they were when the measurements began.
Andy Shepherd, lead study author, and CPOM Director conveyed, “In parts of Antarctica the ice sheet has thinned by extraordinary amounts, and so we set out to show how much was due to changes in climate and how much was due to weather,” he added, “And ice losses are driving up sea levels around the globe, altogether, ice losses from East and West Antarctica have contributed 4.6mm to global sea level rise since 1992.”
Marcus Engdahl of the European Space Agency, a co-author of the study, explaining the importance of satellite missions in order to study our Earth said, “The polar regions are hostile environments and are extremely difficult to access from the ground. Because of this, the view from space is an essential tool for tracking the effects of climate change.”
According to the experts at the University of Cambridge, the northwest part of the Ross Ice Shelf in Antarctica is seen melting 10 times faster due to the ocean water being warm due to the heat of the sun.
Lead study author Craig Stewart from New Zealand’s National Institute of Water and Atmospheric Research. said, “The stability of ice shelves is generally thought to be related to their exposure to warm deep ocean water, but we’ve found that solar heated surface water also plays a crucial role in melting ice shelves.”
