Copernicus Climate Change Service tops news as global temps spike; EU’s climate data backbone. C3S — EU service tracking warming.
A persistent heat dome has driven unprecedented May temperatures across western Europe this week, with the UK and France having broken May records (Kew Gardens provisionally 35.1°C). Ambulance services have reported record call volumes, amber heat-health alerts have been issued, thunderstorms and fires have followed the heat, and officials are urging caution around open water.
The National Science Foundation has begun decommissioning most instruments from the Ocean Observatories Initiative (OOI), a 900+‑sensor system that has tracked ocean climate, currents and hazards for a decade. Lawmakers from both parties have pressed the NSF to halt the plans, arguing the move lacks warning, violates process and could jeopardize coastal safety and weather predictions. Scientists warn the loss will hinder climate monitoring and fishing industries, while officials say the desk keeps advancing priority research.
El Niño has formed in the Pacific and is strengthening toward historic intensity. NOAA and other agencies project a very strong event, with potential to drive extreme weather, disrupt food supplies, and influence global temperatures through late 2026. Governments and markets are preparing for broad regional impacts.
