France's Heat Infrastructure Wasn't Built for June Extremes

France is bracing for a second heatwave exceeding 40°C on June 21, less than four weeks after the first. Schools and farms are adapting months ahead of schedule. The problem: France's national heat response system, architected around July and August peaks, lacks capacity for a compressed, earlier-onset pattern. Current tools—cooling centers, welfare checks, public alerts—were calibrated for the old rhythm. Climate attribution science now moves fast enough to confirm these events reflect shifting temperature baselines. The structural question policymakers face: how rapidly must adaptation infrastructure evolve when extreme heat frequency is already outpacing it?
