According to @CCTV Finance News, according to a recent report by France 24, the latest research shows that as of the end of February this year (the end of the Antarctic summer), the Antarctic sea ice area has shrunk to less than 2 million square kilometers for the first time, only about 1.9 million square kilometers, a record. minimum level. The Antarctic sea ice area has gradually shrunk in recent years due to rising temperatures. Compared to the late 19th century, temperatures in the Antarctic region have risen by about 3°C. It is reported that in 2020, Antarctica will encounter a rare heat wave, with the highest temperature being 9.2°C higher than the average temperature in previous years. And in March of this year, a monitoring site in East Antarctica even observed an anomaly of 30°C higher than normal. The video It is understood that white sea ice can reflect the sun’s heat, but when it is replaced by dark unfrozen sea water, the reflected heat will be less, and the absorbed heat will be more. It will make more sea ice melt, and then absorb more heat energy, forming a vicious circle. In this regard, scientists have warned that the accelerated melting of Antarctic sea ice is a big problem, which will not only significantly affect the polar climate and ecosystems, but will further accelerate the rate of global warming. Baidu Encyclopedia data shows that Antarctica is located at the southern end of the earth, surrounded by the Southern Ocean, and .
