Recently, the coldest place on earth has experienced an unprecedented "hot" weather: the temperature at the southeast polar ice sheet is about 10 to 33 degrees higher than its normal level. Such an abnormal temperature broke the original record of the highest temperature, which also surprised scientists. The coldest location on the planet has experienced an episode of warm weather this week unlike any ever observed, with temperatures over the eastern Antarctic ice sheet soaring 10 Celsius to 33 Celsius above normal. The warmth has smashed records and shocked scientists. Taking Antarctica as the center, the temperature difference between the temperature on March 18 and the normal temperature is simulated based on the American GFS model.

He said that this abnormal high temperature would be considered "impossible" and "unimaginable" before it actually occurred. "Antarctic climatology has been rewritten," tweeted Stefano Di Battista, a researcher who has published studies on Antarctic temperatures. He added that such temperature anomalies would have been considered "impossible" and "unthinkable" before they actually occurred. Of course, the "high temperature" here is relative. The temperature in Eastern Antarctica is no longer minus 40 to 50 degrees, but has risen to minus 10 to 20 degrees - a huge heat wave for Antarctica. What is considered "warm" over the eastern Antarctica is, of course, relative. Instead of temperatures being minus-45.6 or minus-51.1 Celsius, they've been closer to minus-17.8 Celsius or minus-12.2 Celsius. That's a massive heat wave by Antarctic standards. Vostok station is a Russian meteorological observation station located in the center of the eastern ice sheet. It is about 1300 kilometers away from the Antarctic pole and 3488 meters above sea level. It is famous for observing the lowest temperature on the earth (minus 89.2 degrees on July 21, 1983). The average high temperature observed by the observatory in March was about minus 52.3 degrees, but on March 18, the temperature jumped to minus 17.7 degrees. This is also the highest temperature in March observed by the observatory in the 65 years since its establishment. The average high temperature in Vostok — at the center of the eastern ice sheet — is around minus-52.3 Celsius in March. But on Friday, the temperature leaped to minus-17.7 Celsius, the warmest it's been there during March since record keeping began 65 years ago. Svetz glacier At the same time, in western Antarctica, the ice sheet is decreasing - here and the Antarctic Peninsula are one of the fastest warming regions on earth. Warm ocean currents here have also accelerated the melting of Antarctica's Thwaites glacier. This ice body, which is equivalent to the area of Florida in the United States, is known as the "doomsday glacier". Its melting accounts for 4% of the global sea-level rise every year. The western Antarctic ice sheet is losing mass while western parts of the continent and the peninsula are among the fastest-warming regions on Earth. Warm ocean temperatures threaten to destabilize Antarctica's Thwaites Glacier, a slab the size of Florida that contributes about 4 percent of annual global sea level rise. Recent differences between Antarctic and Arctic temperatures and normal temperatures source: climate reanalyzer org Before that, there was an abnormal high temperature at the other pole of the earth. On March 16, the temperature near the Arctic was 10 degrees higher than normal and close to the melting point of the ice. The historically high temperatures in Antarctica follow a pulse of exceptional warmth on the planet's opposite end. On Wednesday, temperatures near the North Pole catapulted about 10 Celcius above normal, close to the melting point. What causes the high temperature? "Both weather events are related to the transport of heat and water to the poles," said Dr. Zachary Rabe, a climate scientist at Colorado State University, on twitter. Alex Sen Gupta, an associate professor at the University of New South Wales in Australia, said strong winds from Australia were the cause of the abnormal temperature in Antarctica. On the Southern Ocean in southern Australia, a series of severe weather systems form extremely strong winds extending from Australia to Eastern Antarctica. Professor Julie albrast, a climate researcher at Monash University in Australia, said that heavy rainfall clouds brought warm and humid air over the eastern Antarctic, which is also the main factor leading to local high temperatures. "It's interesting to know whether there will be the lowest area of sea ice in Antarctica and Antarctica around Antarctica," he said (Xinhua News Agency)
