Results are in for one of the clearest measures of global heating in 2025. It should be raising alarm bells

 The world’s oceans absorbed more heat in 2025 than in any year since
modern records began, according to a major international analysis. Ocean
heat content rose by 23 zettajoules – the equivalent of detonating
hundreds of millions of Hiroshima atomic bombs, or roughly 200 times
humanity’s global electricity consumption in 2023 – according to the
analysis published in Advances in Atmospheric Sciences. Unlike sea surface
temperatures, ocean heat content is a measure of how much excess energy the
world’s oceans are storing over time, including at depth.
