why is antarctica melting
Today, the main reason glaciers have begun to melt is because of human activity. A robotic submarine is about to descend into a dark, water-filled cavern in Antarctica, to try to find out why one of the continent's largest glaciers is melting so fast. We found that the mass melting of the West Antarctic Ice Sheet was a major cause of high sea levels during a period known as the Last Interglacial (129,000-116,000 years ago). A look at â¦ The biggest and most notable impact of these glaciers melting is in the rise of sea level. Almost 90% is in Antarctica, while the remaining 10% is in the Greenland ice cap. Rapid glacial melt in Antarctica and Greenland also influences ocean currents, as massive amounts of very cold glacial-melt water entering warmer ocean waters is slowing ocean currents. Waterâs melting point, 32°F, is a critical threshold for rapid change in polar regions, and only a small fraction of the snow on Antarcticaâs miles-high ice sheet reaches that temperature in summer. Thermometers at the Esperanza Base on the northern tip of the Antarctic Peninsula reached 18.3°C (64.9°F)âaround the same temperature as Los Angeles that day. The warm spell caused widespread melting on nearby glaciers. Antarctica's Thwaites Glacier, described as the "most important" glacier in the world, is now melting faster than previously thought. When sea ice melts, sea level does not change. The net, total behavior of all ice in the Antarctic is causing a significant and accelerating rise in sea level. Researchers trying to understand what's happening have drilled down through seven-hundred metres of ice, to allow a robot submarine to gather information. Antarctica is melting from below and that's bad news. Antarctic sea ice is ice which forms in salt water mostly during winter months. On February 6, 2020, weather stations recorded the hottest temperature on record for Antarctica. Mass melting of the West Antarctic ice sheet, driven by warmer ocean temperatures, was a major cause of extreme sea level rise more than 100,000 years ago, according to â¦ Compared to the Arctic, Antarctica is responding less rapidly to climate change. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. So far, the Antarctic was seen as relatively stable. Antarctica discovery: Melting ice reveals mysterious 300ft-wide 'out of place' object A BIZARRE unexplained object has been uncovered on Google â¦ Officially called the Thwaites Glacier, this mass of ice nestled into the western edge of Antarctica is melting at an alarming rate. Melting land ice contributes to sea level rise. Today, about 10% of land area on Earth is covered with glacial ice. The world's rapidly melting glaciers has disastrous consequences on the animals that rely on them for survival.
