[research: there may be no sea ice in the Arctic summer by the 1930s] A climate change model study published in Nature Communications on the 6th suggests that even in low-emission scenarios, the Arctic may be free of sea ice as early as the 2030s, about 10 years earlier than previously estimated. These latest findings highlight the significant impact of human activities on the Arctic and demonstrate the importance of planning and adapting to the Arctic's seasonal ice-free in the near future.
