According to comprehensive foreign media reports, on the 12th local time, the United States officially released the latest report saying that in 2023, the Arctic region experienced the warmest summer since records began in 1900, triggering unusual wildfires and melting glaciers, bringing a series of threats to the rest of the world.
According to Agence France-Presse, the 2023 Arctic Report released by the National Oceanic and Atmospheric Administration (NOAA) shows that the surface temperature in the Arctic in the summer of 2023 is the highest since at least 1900, or more than a century.
The average temperature in the Arctic from July to September 2023 was reported to be 6.4 degrees Celsius, the highest in more than 120 years. The average summer temperature in the Arctic rises by 0 17 degrees Celsius every 10 years. 2023 is the sixth hottest year in the Arctic, with an average temperature of minus 7 degrees Celsius.

According to the report, the Arctic is warming about four times faster than the rest of the planet, mainly due to a vicious cycle of sea ice loss, known as the "Arctic amplification effect".
At the same time, Greenland's ice sheet lost about 350 trillion pounds (158.7 billion metric tons) of ice due to the melting of glaciers due to high temperatures, continuing a trend of land ice loss since 1998, Reuters reported.
The report also details "conclusive evidence of greening in the Arctic", with shrubs and greenery increasing as temperatures rise, precipitation increases, and permafrost melts.
The report notes that the "peak tundra greenness" in the Arctic reached the third-highest level in 24 years of study. "Arctic greening" accelerates climate change by releasing large amounts of carbon dioxide stored in permafrost.
The annual report also shows that extreme weather and climate events with global implications are becoming more frequent. For example, parts of northern Canada and the Canadian Arctic archipelago have seen extreme wildfire seasons due to warmer climates and below-normal precipitation.
"The most important message from this year's report is that now is the time to act. As a national and global community, we must dramatically reduce greenhouse gas emissions that contribute to climate change. ”
