Short read: Europe can’t just air-condition its way out of the heatwave meltdown

Every May-June, as Delhi and Bombay brace for 45 degree afternoons, we get a reminder of how well Indian buildings, habits and infrastructure have learned to live with heat: thick curtains drawn at noon, siestas built into the workday, ACs that have become almost a utility rather than a luxury. So, it has been strange to watch Europe, this summer, discover searing heat the way India discovers snow, with wonder followed swiftly by chaos. This piece from The Economic Times captures that discovery in real time.

As temperatures climbed past 40 degrees Celsius across France, Germany, Britain and Spain this summer, air conditioners flew off store shelves. Demand surged so fast that Asian manufacturers ramped up supplies to a continent that has traditionally relied far less on cooling than North America or large parts of Asia. Even Indian AC makers, the piece notes, have spotted an opportunity in a market that barely existed for them a decade ago. But the article’s real argument is that this shopping spree is treating a symptom, not the disease:

“Europe is discovering that its homes, hospitals, railways, roads and power systems were built for a climate that no longer exists. The challenge now is not simply how to cool buildings. It is how to redesign an entire society that was engineered to keep people warm.”

That single idea — an entire continent engineered for the wrong problem — runs through the piece. European apartments, the article explains, were built with thick walls, heavy insulation and limited ventilation, features that were sensible defences against winter cold and become traps once the mercury sits above 35 degrees for days on end. As the piece puts it, quoting experts cited by Reuters:

“Cooling systems alone cannot compensate for building designs that trap heat. Instead, cities will need external shading, better ventilation, reflective materials and passive cooling techniques.”

Paris has responded with tree planting and urban cooling programmes, but the article is candid that most of the continent’s housing stock remains poorly suited to hotter summers, and that the conversation is only now shifting from emergency response to long-term redesign.

What struck us most, though, was how far this heat is reaching beyond buildings. Tram tracks in Germany buckled during the heatwave. Highways cracked and deformed. These sound like footnotes, but the article treats them as early warnings for engineers who have spent decades designing rail lines, signalling systems and road surfaces around frost resistance and winter durability, not heat tolerance. As the piece notes, what was once dismissed as an exceptional weather event is increasingly a condition that transport networks must routinely withstand, which means new alloys, revised expansion tolerances and different paving materials are no longer optional extras but design requirements.

It is a useful reminder, reading this from Bombay, that resilience is rarely a single fix. India did not become heat-ready because of air conditioning alone. It took generations of architectural instinct, adjusted daily rhythms and, yes, a lot of hardware layered on top. Europe is now being asked to compress that adjustment into a few punishing summers. Worth a full read if you want to see what it looks like when a continent has to unlearn a few centuries of building for winter, fast.
