guangming daily, beijing, september 7 (reporters chen haibo and cui xingyi)the china meteorological administration recently released the polar climate change annual report (2023). the annual report states that the arctic and antarctic are sensitive areas to climate change. the china meteorological science academy used a variety of climate data to analyze and show that in 2023, the arctic and antarctic regions showed a sustained climate change amplifier effect, with frequent extreme events, which had a significant impact on local ecology and global weather.
the annual report shows that the temperature in the antarctic region is slightly higher than usual, with large differences between the east and west regions and the coexistence of extreme cold and extreme warm events. in 2023, the average annual temperature of the antarctic continent was minus 31.86 degrees celsius, 0.05 degrees celsius higher than usual. the average annual temperature in the antarctic peninsula and the west antarctic continued to rise rapidly. in 2023, three meteorological stations recorded the second highest autumn temperature in history and seven stations recorded the third highest temperature in history. during the polar night on july 7, 2023, the temperature at the south pole soared 40 degrees celsius in one day, from minus 74 degrees celsius to minus 34 degrees celsius. there was an anomaly of cold in east antarctica. from mid-july to the end of august, four consecutive extreme cold waves occurred in most parts of antarctica.
although the warming in the arctic has slowed down, it still experienced the warmest summer since 1979, with an overall distribution of "warm land and cold sea". the annual report shows that from 1979 to 2023, the warming of the arctic was 3.4 times the global warming rate during the same period. the average annual temperature in the arctic in 2023 was minus 9.19 degrees celsius, 0.97 degrees celsius higher than normal. in terms of regions, the continental region around the arctic ocean, especially northern canada and the barents sea-kara sea coast, will be warmer by more than 2.0 degrees celsius in 2023. on june 26, 2023, the temperature at the highest point of the greenland ice sheet reached 0.39 degrees celsius, exceeding zero, causing large-scale melting of the ice sheet.
