China News Service,Express information December 13. Comprehensive foreign media reports that on the 12th local time, the US official announced the latest report that the North Pole region in 2023 has experienced the warmest summer since 1900, which has triggered unusual wildfire and glaciers melting., Bring a series of threats to other parts of the world.
According to Agence France -Presse, the "2023 Arctic Report" released by the National Oceanic and Atmospheric Administration (NOAA) shows that in the summer of 2023, the surface temperature of the Arctic has been at least since 1900, or the highest level of more than a century.
According to reports, the average temperature in the Arctic region from July to September 2023 was 6.4 degrees Celsius, refreshing the highest record in more than 120 years.The average summer temperature in the Arctic increases by 0.17 degrees Celsius every 10 years.2023 is the sixth hottest year of the Arctic, with an average temperature of minus 7 degrees Celsius.
It is reported that the speed of the Arctic warming is about 4 times that of the other parts of the earth, which is mainly caused by the vicious cycle of the sea ice loss and is called the "Arctic amplification effect".
According to Reuters, at the same time, due to the melting of glaciers, Greenland's ice sheet lost about 3.5 trillion pounds (158.7 billion metric tons) ice, which continued the trend of land ice loss since 1998.
The report also explained in detail the "indexed evidence of the Arctic Greening". As the temperature rises, the precipitation increases, and the permanent frozen soil melts, shrubs and green trees increase.
The report pointed out that the North Pole's "Moss -ray Green Peak" reached the third high level in the 24 years of research.The "Arctic Greening" will release a large amount of carbon dioxide stored in permanent frozen soil, thereby accelerating climate change.
The annual report also shows that extreme weather and climatic events with global influence are becoming more frequent.For example, the climate of the climate of some parts of northern Canada and the Canadian Arctic Islands has warmed up, and the precipitation is lower than the normal level, resulting in an extreme wildfire season in these regions.
