- Western Europe experienced its warmest summer on record, with severe drought conditions affecting the UK, France, Hungary, Romania, and Serbia, and major rivers experiencing exceptionally low flows.
- Sea surface temperatures reached record highs, driven by global heating and a strong El Niño weather phenomenon in the Pacific.
- Climate advocates cite the findings as an urgent warning signal just two months before Cop31, the next UN climate summit, calling for accelerated emissions cuts and enhanced climate resilience measures.

Climate advocates cite findings as warning ahead of Cop31 summit
Gareth Redmond-King, head of international programme at the Energy and Climate Intelligence Unit, characterized the record temperatures as another urgent signal just two months before the UN climate summit Cop31, calling for world leaders to accelerate greenhouse gas emissions cuts toward net zero.
“World leaders gathering ahead of Cop31 in the coming weeks know the solution: cut greenhouse gas emissions rapidly towards net zero while strengthening resilience to the impacts already locked in.”
