摘要
一项研究显示,北极“在15年内可能会在夏季基本无冰”。该研究利用统计模型预测了北极冰层的未来数量,其表明在21世纪30年代的十年里,极有可能是在2034年,北极可能会在夏季无冰。海冰是冻结的海水,每年夏季融化,然后每年冬季重新冻结。由于全球变暖,过去几十年来,北极夏季海冰的数量一直在稳步减少。美国国家海洋和大气管理局称,2019年北极夏季海冰水平仅次于历史最低纪录。
A study suggests that the Arctic“may be essentially ice-free during summer within 15 years.” The study used statistical models to predict the future amount of Arctic ice,which suggested that the Arctic could be ice-free in the summer during the decade of the 2030s-most likely in the year 2034.
