The Arctic region experienced its warmest summer this year since records began in 1900, the 2023 Arctic Report Leaflet, released Dec. 12, said.
The report says that the average temperature in the Arctic region from July to September this year is 64 degrees Celsius, the highest in more than 120 years, shows that climate change is intensifying. In addition, the average temperature in the Arctic region in the past year was minus 7 degrees Celsius, ranking sixth on the list of "high temperatures" in the Arctic since 1900.
Sea ice extent in the Arctic continues to decline this year, the sixth-lowest since satellite records began in 1979. The area of "Chen Bing" is about the same as in 2022, but it is much less than in the 80s of the 20th century, and there are only a small number of "Chen Bing" that are more than 4 years old.
The 2023 level of "greening" in the Arctic tundra zone is the third highest in 24 years on satellite records, continuing the trend of increasing shrubs and green trees. Due to the cold climate in the Arctic tundra belt, only plants such as mosses used to grow. Over the past few decades, due to global warming, shrubs and green trees have grown in some areas, and in some cases even forests. Researchers believe that this change in vegetation creates a darker surface morphology that absorbs more solar heat and exacerbates local climate change.
The Arctic Report is a peer-reviewed report published annually since 2006 and funded by the U.S. federal government. This year's report was completed by 82 researchers from 13 countries and regions.
Rick Spinrad, Administrator of the National Oceanic and Atmospheric Administration, said: "The important message from this year's report card is that action is ...... nowThe greenhouse gas emissions that drive these changes must be drastically reduced. ”
