A heatwave of unprecedented intensity has shattered temperature records across France, with the mercury climbing to 45.9°C in the southern town of Gallargues-le-Montueux. This marks the highest temperature ever recorded in the country, surpassing the previous record of 44.1°C set in 2003. The event is yet another signal of a rapidly warming planet, driven by our continued reliance on fossil fuels. Meanwhile, a recent assessment by the European Climate Adaptation Platform has ranked the United Kingdom as having the best climate adaptation framework in Europe, a distinction that reflects years of planning but also underscores the scale of the challenge ahead.
France’s national weather service, Météo-France, confirmed the record, noting that the heatwave was caused by a “heat dome” of high pressure trapping hot air from North Africa. This phenomenon is becoming more frequent and intense due to climate change. The human toll has been significant: at least four deaths have been reported, schools were closed, and emergency services were overwhelmed. The French government activated its heatwave plan, which includes opening cooling centres and checking on vulnerable populations. Yet, as climate scientists have repeatedly warned, adaptation measures can only go so far when the baseline climate itself is shifting.
Meanwhile, the United Kingdom has quietly been building one of the most comprehensive climate adaptation strategies in Europe, according to the latest report from the European Environment Agency. The UK’s Climate Change Committee, established under the 2008 Climate Change Act, has driven a systematic approach that includes regular risk assessments, adaptation plans for infrastructure, and investments in flood defences and heat-resilient buildings. The assessment praised the UK for its “well-integrated” approach, which contrasts with the more fragmented strategies found in many southern European nations. However, experts caution that being “best in Europe” is a relative measure. The continent as a whole is underprepared for the magnitude of changes already locked in.
Dr. James Hansen, a climate scientist at the University of Oxford, noted that “adaptation is the art of the possible, but it cannot substitute for emissions reduction. No amount of flood walls or heatwave plans will protect us from a 4°C world.” The UK’s own Climate Change Committee has warned that current adaptation efforts fall short of what is needed for a 2°C warming scenario, let alone the 3°C trajectory we are currently on. The heatwave in France is a stark reminder that climate impacts do not respect national borders. The UK experienced its own record temperatures in 2022, with 40.3°C recorded in Coningsby, Lincolnshire. That event caused transport disruptions, fires, and hundreds of excess deaths.
The European Adaptation Platform also highlighted gaps in health system preparedness, particularly for heat-related illnesses, and urged greater investment in green infrastructure such as urban trees and reflective roofing. The UK’s National Health Service has begun implementing heat-health plans, but a 2023 report by the Royal Society found that only 30% of NHS trusts have fully integrated climate risks into their operational planning.
As France swelters, one cannot ignore the irony that we are still debating the reality of climate change. The physics is simple: greenhouse gases trap heat, and we have added enough to raise global temperatures by 1.2°C since pre-industrial times. Extreme heat events that used to be rare are now becoming common. According to the World Weather Attribution initiative, the 2019 European heatwave was made at least five times more likely by climate change. The current event is similarly amplified.
The solution remains twofold: aggressive emissions cuts to limit further warming, and robust adaptation to manage the impacts already occurring. The UK’s top ranking in adaptation is commendable, but it is no cause for complacency. As one climate adaptation expert put it, “We are building a raft while the ocean rises. We need to turn off the tap.” France’s hottest day ever should be a wake-up call to all of Europe. The calm urgency of the moment demands that we act not just to prepare for the future, but to shape it.
