A severe heatwave is gripping western Europe, producing unprecedented temperature records across multiple countries simultaneously. France recorded its hottest day since measurements began in 1947, with temperatures reaching 43°C in parts of Poitou-Charentes, 42°C in Bordeaux, and 39.6°C in Paris. The UK recorded its hottest June day on record at 36.1°C in Gosport, Hampshire, with rare red heat alerts extended to parts of Britain and more than 1,000 schools shut or closing early. Spain hit 42.5°C in Bilbao. Italy activated sixteen red alerts across its northern and central regions. At least forty people drowned in heatwave-related incidents in France alone. Across the continent, landmarks including the Louvre and the Eiffel Tower closed early, barbecue bans were introduced in German cities, and water conservation warnings were issued in Brandenburg, Hesse, and North Rhine-Westphalia. The heatwave is expected to spread east across Europe through the week. The Copernicus Climate Change Service has consistently found that Europe is the world’s fastest-warming continent, heating at roughly twice the global average rate.
The received wisdom
The mainstream framing on European heatwaves is now well-established: the scientific consensus holds that climate change is making extreme heat events more frequent, more intense, and more deadly. On this, the evidence is not particularly contested. The policy prescription that follows from that consensus is, broadly, decarbonisation — reducing the greenhouse gas emissions that drive warming. In this framing, installing more air conditioning is at best a temporary palliative and at worst a counterproductive measure that increases electricity demand, leaks refrigerant gases, and intensifies the urban heat island effect by expelling hot air onto streets, potentially raising city temperatures by two to three degrees Celsius. The European environmental left has argued for decades that the solution to heat is better building insulation, more urban greenery, and behavioural adaptation — and that making people comfortable in the heat via air conditioning merely masks the urgency of the transition. Only around 25 percent of French households have air conditioning, compared to 50 percent in Spain and Italy and 90 percent in the United States and Japan. This disparity has been a source of quiet progressive pride: Europe, the argument goes, is not an air-conditioned civilisation because it has better values about energy use.
A different read
That framing is becoming increasingly difficult to sustain, and the political crack in it is now visible. The leader of France’s Écologistes party, Marie Tondelier, broke publicly with what the French call “anti-clim” dogma this week, acknowledging that “there are places where we just can’t do without it now.” This is not a trivial admission. For decades, the French environmental left treated air conditioning as a synecdoche for American-style overconsumption, a cultural and political symbol as much as a technology. To hear the head of the Greens concede the point is a sign that the argument has moved.
Marine Le Pen’s Rassemblement National, by contrast, moved fast. The party is calling for a national “plan clim” that would equip all schools and hospitals with air conditioning and offer €20 billion in government-backed interest-free loans to help 30 to 40 million French households install units. Paris regional council president Valérie Pécresse has announced plans to equip all Paris buses and trains with air conditioning by 2032. These proposals are being dismissed in elite commentariat circles as “opportunistic and uncosted” — and the RN plan almost certainly is both. But the opportunism cuts both ways: the environmental left has had a generation to make building insulation and passive cooling work at scale, and while progress has been real, schools and hospitals across France are routinely closing in June because the buildings are simply too hot to use safely.
The philosophical problem at the heart of the anti-air-conditioning position is that it conflates means and ends in a way that is increasingly lethal. The goal of climate policy is to prevent premature deaths and severe human suffering. Air conditioning, in a continent that is heating faster than anywhere else on earth, prevents premature deaths. The argument that installing air conditioning is somehow in tension with climate goals confuses the level at which the trade-off actually operates. An individual household’s decision to install a heat pump-powered air conditioner does not meaningfully change global emissions trajectories. What it does do is keep elderly people alive in August.
The broader historical comparison is instructive. The United States built an air-conditioned civilisation in the twentieth century not primarily because of cultural indulgence but because of a pragmatic assessment that extreme heat was incompatible with productive economic activity and human dignity in regions like the American South. Europe is now confronting the same physical reality that the American South confronted in the 1950s and 1960s. The difference is that Europe is confronting it with a public health infrastructure — schools, hospitals, care homes — designed for a climate that no longer exists, and an ideological tradition that treated the American response as a cautionary tale rather than a lesson. The Louvre spokesperson’s statement that “the building was not sufficiently adapted to climate change” is technically accurate. It is also a description of most of the public buildings in France.
The environmental objections to air conditioning are real but they are second-order. Electricity grids can be decarbonised — France’s nuclear fleet already means that French air conditioning has a much lower carbon intensity than most of Europe. Refrigerant technology is improving. The urban heat island effect is a genuine concern for urban planners but it does not justify leaving hospital patients, schoolchildren, and elderly residents without cooling during a record-breaking heat emergency. The correct response to the second-order problems is to solve them — better refrigerants, greener grids, smarter urban design — not to treat the first-order problem (people dying of heat) as politically acceptable collateral damage in the service of an ideological position that is, in any case, losing public support at speed.
What to watch
Watch whether the French government’s response to this week’s crisis accelerates any formal revision of building norms that currently discourage air conditioning installation in new construction. Watch, too, whether the EU’s energy efficiency directives — which have historically been drafted in a northern European temperature context — are revised to accommodate the reality of a southern and western European climate that is materially warmer than when those standards were written. The political signal to track in France is whether the Macron-era centrist coalition that has long occupied the ground between green dogma and RN populism produces its own coherent air conditioning policy, or whether it cedes that ground entirely to the right. The RN’s willingness to be the party of practical adaptation rather than ideological purity on this question is a genuine electoral opportunity. The question is whether anyone else takes it seriously before the next election.
