Heatwave kills 2,300 as alerts outpace action

France recorded one of its hottest days in history on 23 June, with 54 departments under the highest red alert and around 1,800 schools closed (TF1 Info). The World Meteorological Organization counted 23 European countries under extreme heat, from Portugal to Romania, warning that overnight temperatures too high for the body to recover matter more than the daytime peak (WMO). Copernicus had flagged the pattern weeks earlier: temperatures more than 10°C above average across western France, England and Wales in late May (Copernicus). The continent saw the danger coming. What happened after the warnings arrived is a different story.

Brussels can warn. It cannot order a town hall to open a cooling room.

The EU's heat tools are real but stop well short of command authority. The European Climate Law (the regulation binding the EU to net-zero by 2050) requires member states to keep improving their adaptation plans. It does not tell a mayor when to open a cooling centre or a rector when to cancel an exam (European Climate Law). EU occupational safety directives require employers to assess heat risks, yet set no Europe-wide maximum working temperature (EU-OSHA). Copernicus provides satellite monitoring. The Civil Protection Mechanism (the EU system countries use to request emergency help) stands ready. But the decision to close a school, halt a building site, or check on an elderly person living alone belongs to national, regional or municipal authorities.

That split turned the same heatwave into sharply different outcomes.

Three countries, three protection chains

France ran its most centralised response. An interministerial crisis cell coordinated from Paris. Prefects, the central government's representatives in each department, ordered school closures, reinforced hospitals and managed river-temperature limits that forced a nuclear reactor offline (Le Monde, TF1 Info). The system works because one official in each department has both the authority and the duty to act.

Italy showed how worker and elderly protection can be written into enforceable law. Regional ordinances banned outdoor work in agriculture and construction during peak hours (Sky TG24). Milan's health authority sorted more than 464,000 residents over 75 by medical risk so services knew whom to check first (AgenSalute).

Poland exposed the gap between rules and reality. Employers must provide cold drinks above certain temperatures, but automatic work stoppages in dangerous heat remain a legislative proposal, unlikely before 2027 (Gazeta Prawna). Parliament has not decided whether extreme heat should trigger enforceable limits rather than employer discretion.

Counting the dead, not the saved

WHO/Europe reported that heat killed more than 200,000 Europeans over four years, calling nearly all those deaths preventable (WHO, Euronews). Imperial College London researchers estimated 2,300 heat deaths across 12 European cities over ten days in this June episode, attributing 65% to climate change (Imperial College). The European Environment Agency found 16,000 European schools already experience days above 30°C outside summer holidays, a figure projected to double by the 2050s (EEA).

Europe is better prepared than after the 2003 catastrophe. WHO's updated heat-health guidance, launched on 11 June in Berlin, draws on two decades of evidence across public health systems (WHO). But better plans have not guaranteed safer classrooms, homes or work sites. Available public reporting from this episode did not yet combine excess mortality, school closures and workplace heat injuries into a single comparable account. France counted drownings quickly; consolidated heat-death numbers were absent. The EEA itself says it lacks systematic data on which local protection measures were actually carried out (Climate-ADAPT).

Europe's forecast infrastructure has outpaced its protection infrastructure. Until someone is accountable for proving the alert reached the elderly resident, the overheated classroom and the midday construction site, the continent will keep counting the dead rather than the lives it saved.
