Copernicus’ tenth report documents recent highs in ocean heat, sea level and acidification. Accumulated energy drives marine heatwaves, oxygen loss, coral bleaching and rising risks for islands and polar regions.
The first Atmosphere Watch examines air pollution during the first eight months of 2026. Nearly 40% of the world's population was exposed to ozone levels classified as extremely high in the analysis.
Sea-surface temperature averaged 20.96°C, delivering a second consecutive monthly record, Copernicus says. The tropical Pacific, Atlantic and Mediterranean concentrated anomalies, while July tied the second-highest global temperature at 1.47°C above pre-industrial levels.
