Scientists have recorded the highest temperature ever measured in the world’s oceans, as climate change combines with a powerful El Niño in the tropical Pacific. 科学家记录到全球海洋温度达到有史以来最高值,这是气候变化与热带太平洋强厄尔尼诺现象共同作用的结果。
The global average sea-surface temperature hit a record 70 degrees on Aug. 22, according to Europe’s Earth observation agency Copernicus, which has been tracking the metric daily since 1979. The previous single-day record was measured in March 2024. 欧洲地球观测机构哥白尼气候变化服务局数据显示,8月22日全球平均海表温度达到70华氏度(约21.1摄氏度)的历史峰值。该机构自1979年起每日监测该指标,此前的单日最高纪录出现在2024年3月。
“El Niño is adding heat to the system, but it is doing so on top of decades of human-driven warming,” said Samantha Burgess, strategic lead for climate at Copernicus’ European Center for Medium-Range Weather Forecasts. 哥白尼欧洲中期天气预报中心气候战略负责人萨曼莎·伯吉斯表示:“厄尔尼诺正在给气候系统增加热量,但这是在人类活动导致数十年变暖基础上的叠加。”
“As ocean temperatures continue to rise, the risks to marine ecosystems and coastal communities also increase,” she said. 她指出:“随着海洋温度持续上升,海洋生态系统和沿海社区面临的风险也在加剧。”
Higher ocean temperatures contribute to sea level rise and increase the chance of extreme weather events, as warmer water transfers more heat and moisture to the atmosphere, intensifying storms and heat on land. Warmer oceans also have a reduced capacity to absorb carbon dioxide. 海洋温度升高会导致海平面上升,并增加极端天气事件发生概率——较暖海水向大气输送更多热量和水汽,从而加剧陆地上的风暴和高温现象。变暖的海洋还会降低吸收二氧化碳的能力。
Record temperatures have already been measured in isolated areas of the world’s oceans including the western Mediterranean Sea as well as at the Earth’s poles, driven mainly by human-made climate change. Copernicus expects the trend to continue, with ocean temperatures now being supercharged by El Niño. 受人为气候变化主要驱动,全球部分海域(包括地中海西部)和地球两极已测得创纪录温度。哥白尼机构预计这一趋势将持续,目前厄尔尼诺现象正在给海洋温度”火上浇油”。
The August record is particularly worrying because global ocean temperatures are typically highest in March and April, after the Austral summer, Copernicus said. 哥白尼机构指出,8月创纪录尤其令人担忧,因为通常南半球夏季过后的3-4月才是全球海洋温度最高时段。
