On a Thursday morning in Brussels, Simon Stiell, the executive secretary of the UN Framework Convention on Climate Change, sat before a European Parliament committee and delivered a warning that went well beyond temperature charts. This past summer, he said, had killed tens of thousands of people across Europe alone, while floods, fires and record heat had hammered ports, power stations and harvests to the tune of roughly €180 billion in losses — and that figure is still being counted. The numbers behind his argument were not abstract. August 2026 tied with July 2023 as the hottest month ever recorded on Earth, according to the EU's Copernicus Climate Change Service.

Global average temperatures reached 1.65°C above pre-industrial levels, while sea surface temperatures also broke records. From forced migrations driven by extreme weather in sub-Saharan Africa to choked trade routes in southern Europe, the disruption was, in Stiell's framing, no longer a future risk but a present economic emergency spreading across continents. What made his address unusual was its target.

Stiell directed his sharpest language not at the climate itself but at the political manoeuvre of casting climate policy as a culture-war issue. Populist parties in the EU and elsewhere have argued for rolling back emissions-cutting measures, yet Stiell contended that abandoning climate action is, in practical terms, a vote for higher food prices, greater inflation, eroded sovereignty and reduced fiscal room for public services.
