Ocean Temperatures Hit Record Highs Ahead of El Niño, Raising Climate Concerns
Global ocean temperatures have reached record levels, with average sea surface temperatures climbing to 21°C, surpassing previous highs recorded in 2023 and 2024.
Scientists say the world's oceans are experiencing significant heat stress, with temperatures expected to rise further as El Niño develops. The natural climate pattern, which warms the tropical Pacific Ocean, typically lasts for several months and can intensify global temperatures.
The combination of record-breaking ocean heat and the onset of El Niño is expected to increase the risk of extreme weather events, marine ecosystem disruption and broader climate impacts worldwide.
