The Earth’s oceans were hotter in 2025 than in any year since modern measurements began, marking a dangerous new record.  New analysis published in the peer-reviewed journal Advances in Atmospheric Sciences on Friday found that the upper 2,000 meters (6,561 ft.) of the ocean absorbed a record-setting 23 zettajoules more energy than in 2024—equivelant to roughly 37 times more energy than the world consumed in 2023.  The study examined ocean heat content, which measures how much excess heat
