Average temperatures across the world’s oceans reached an all-time high in 2024, a new multi-team study shows. The temperatures surpassed even those of 2023, which themselves represented a marked uptick over any previous years on record,

The average temperature in China's coastal waters rose for a second consecutive year in 2024 to a record 21.50 degrees Celsius (70.7 degrees Fahrenheit), authorities said, in a year that was the world's hottest since records began.

A new study has found that ocean temperatures reached record highs in 2024. The findings, published in The Advances in Atmospheric Sciences, were the results of more than 50 researchers across seven different countries looking at everything from surface temperatures to what was happening in the depths and crunching the data.
