Oceans hit highest temperature on record

The world's oceans have reached their highest recorded temperature at 21.1°C (70°F), driven by human-caused climate change combined with the growing El Niño weather phenomenon. This record is particularly concerning because it occurs earlier than the typical seasonal peak and before El Niño reaches its full strength, suggesting even warmer conditions ahead. Warmer oceans can trigger extreme weather, raise sea levels, and harm marine ecosystems.
