The world's oceans absorbed a record amount of heat in 2025, taking in around 23 zettajoules — equivalent to roughly 40 times humanity's total annual energy use. Scientists link the warming to accelerating sea-level rise, as thermal expansion pushes water levels higher. The findings renew concern about the pace of climate change and the oceans' diminishing capacity to buffer global warming.
Why now: New research showing record ocean heat content has just been published, drawing attention to accelerating climate impacts.
