全球海洋温度创下有记录以来最高水平,恰逢夏季本应给海洋降温之时

8月22日,全球海洋日均表面温度创下有记录以来的最高值,打破了2024年创下的纪录,一场异常强劲的厄尔尼诺现象正推动2026年成为有记录以来最热的一年。

8月22日,全球海洋平均表面温度达到21.104摄氏度(69.99华氏度),是有记录以来最高的单日读数,超过了2024年3月创下的21.09摄氏度的此前纪录。这一里程碑颇不寻常,因为南半球的冬季通常会使全球海洋温度在8月降温,而不是刷新纪录。

科学家指出,6月开始的一场异常强劲的厄尔尼诺现象是主要推手。据Berkeley Earth称,2026年成为有记录以来最热年份的概率已从7月的约12%跃升至8月的69%。研究人员将此次事件描述为提前预演了原本要再过十年左右地球才可能达到的气温水平。

这股热浪已经对陆地产生了明显影响:包括莱茵河在内的欧洲多条河流,在极端高温和干旱中降至有记录以来的最低水位,给整个欧洲大陆的航运和农业带来压力。
