The oceans just keep getting hotter
摘要
一项发表于《大气科学进展》期刊的研究显示，全球海洋吸热现象持续加剧。自2018年起，国际研究团队持续监测海洋吸热量，2025年海洋吸收的热量再创新高，达到23泽塔焦耳，显著高于2024年的16泽塔焦耳。这已是全球海洋吸热量连续第八年打破纪录。该研究由来自美国、欧洲和中国的50多位科学家共同完成。
Since 2018, a group of researchers from around the world has crunched the numbers on how much heat the world’s oceans are absorbing each year. In 2025, their measurements broke records once again, making this the eighth year in a row that the world’s oceans have absorbed more heat than in the years before.
The study, which was published Friday in the journal Advances in Atmospheric Science, found that the world’s oceans absorbed an additional 23 zettajoules’ worth of heat in 2025, the most in any year since modern measurements began in the 1960s. That’s significantly higher than the 16 additional zettajoules they absorbed in 2024. The research comes from a team of more than 50 scientists across the United States, Europe, and China.
A joule is a common way to measure energy. A single joule is a relatively small unit of measurement—it’s about enough to power a tiny lightbulb for a second, or slightly heat a gram of water. But a zettajoule is one sextillion joules; numerically, the 23 zettajoules the oceans absorbed this year can be written out as 23,000,000,000,000,000,000,000.
