Copernicus Climate Change Service (C3S)

Copernicus Climate Change Service (C3S): Recently, the European Union’s Copernicus Climate Change Service (C3S) reported that May 2025 was the second-warmest May with global temperatures 1.4°C above the 19th-century average.

• Key Highlights: Regional Hotspots: Unusually high temperatures were recorded in the Middle East, West Asia, Western Antarctica, Northeastern Russia, and Northern Canada, raising risks of heatwaves, wildfires, glacier melt, and biodiversity loss.

  o Uneven Climate Action: While China and the EU have reduced emissions, regions like the U.S. under older fossil fuel policies and some large corporations have contributed to rising emissions, leading to uneven global progress.

  • About C3S: One of six thematic services under the Copernicus Earth Observation Programme of the European Union.

  o Operational Structure: It operates through a network of research infrastructures across Europe and the world.

  o Purpose: Provides reliable data on past, present, and future climate trends to support informed decisions.

  o Scientific Basis: Draws from research under the World Climate Research Programme (WCRP) and user needs identified by the Global Climate Observing System (GCOS).

  o Implementation: Managed by the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf of the European Commission.
