Extra-polar ocean average temperature reached 21.1°C, a new global record
GK and monthly revision
Global ocean records hottest day ever
The Copernicus Climate Change Service reported that extra-polar ocean regions recorded an average temperature of 21.1°C, surpassing the previous record set in March 2024. This marks the hottest day ever observed for global oceans outside polar zones, indicating accelerating marine heatwaves driven by climate change. Rising ocean temperatures threaten marine ecosystems, intensify extreme weather events, and contribute to sea-level rise through thermal expansion. For competitive exams, this data is critical for environment, geography, and climate change sections, especially questions on Copernicus reports, ocean warming trends, and IPCC-linked findings.
