The latest update in Antarctica's historical high temperatures was brought to light by the Esperanza base , Argentina's Antarctic observatory. The tweet is below.

After reviewing the report, the World Meteorological Organization (WMO) will officially recognize this record. The highest temperature ever recorded in Antarctica was 17.5 ° C on March 24, 2015.

Randall Chelveny, a reporter of extreme weather and climatic events at the WMO, said the observed temperature rise was due to a local Fern phenomenon . The following animation shows the 850hPa high-level weather chart on the Antarctic Peninsula, based on the global atmospheric circulation model provided by the National Environmental Prediction Center of the United States National Weather Service. The colors in the animation represent the temperature of the atmosphere, with the closer to red the higher the temperature. The high-rise weather chart is based on the Fern phenomenon, which significantly raised the temperature in Antarctica. You can visually check the warm air blowing.

Ice sheet the size of 30 million km 3, which is also said to contain about 90 percent of the Earth's surface of fresh water will exist in the Antarctic. It is estimated that if this ice sheet melts, the sea level on earth will rise by about 60m. It has been reported that the temperature of the Antarctic has risen by 3 degrees Celsius over the past 50 years, and as a result, the annual melting of the ice sheet has increased about six times from 1979 to 2017.

The following image captured by the European observation satellite Sentinel-1 shows a large crack in Pine Island's glacier, located in western Antarctica, before February 6 when Antarctic record temperatures were recorded. This is a satellite image showing that has entered. WMO reports that glacier segregation on Pine Island has become more frequent in recent years, with photographs taken on February 2 (left) and February 5 (right).

'The warming trend will continue to progress. We must be aware of the fact that the climate is changing,' Chelveny said.

The highest temperature observed so far in the Antarctic region is 19.8 degrees Celsius, which was observed on Signy Island on January 30, 1982.
