Early heatwave in Europe: record temperatures and climate impacts
Much of Europe is experiencing an unusually early heatwave , marking a new and alarming sign of the growing impact of climate change. The continent, where temperatures are rising faster than in other regions, is facing unprecedented environmental challenges. London recorded its highest temperature for May on Monday, while French authorities issued multiple warnings to cope with the sudden surge.
Historical context of climate change and recording an early heat wave in Europe
To understand the dimensions of any early heatwave in Europe, one must consider the historical context of climate change. Since the Industrial Revolution, greenhouse gas emissions have been rising, leading to gradual global warming. Reliable reports, such as those from the European Copernicus Climate Change Service and the World Meteorological Organization, indicate that since the 1980s, Europe has warmed at twice the global average. This acceleration has made heatwaves more frequent and intense across at least 95% of European landmasses, explaining the occurrence of extreme weather events at unexpected times of the year, such as May.
Historic records in Britain
The temperature in Kew Gardens, southwest London, reached a record high of 34.8 degrees Celsius on Monday. The UK Met Office explained that this was the highest temperature ever recorded in May, surpassing the previous record of 32.8 degrees, set in 1922 and again in 1944, by two degrees. The Met Office confirmed that such heat is exceptional for Britain, even at the height of summer. Greg Dewhurst, a weather expert at the Met Office, noted that this level is significantly higher than the average for this time of year, which is typically around 17 or 18 degrees Celsius in London.
Regional and international repercussions of extremist phenomena
The effects of these changes are not limited to mere numbers recorded on thermometers; they extend to far-reaching economic, health, and environmental repercussions. Locally and regionally, the high temperatures strain electricity grids and negatively impact crops unaccustomed to such early droughts, in addition to posing direct health risks to vulnerable populations. Internationally, what is happening in Europe serves as a wake-up call for the rest of the world to accelerate plans for transitioning to clean energy. Scientists say that climate change caused by human activity is intensifying extreme weather events such as heat waves, droughts, and floods. Dewhurst pointed to the increasing frequency of extreme events worldwide, with records being broken at an accelerating rate, noting that this is a clear indicator of ongoing climate change.
Heatwave continues in France, with deaths reported
In the Gard region of southern France, temperatures reached 30 degrees Celsius on Sunday. François Jourand, a meteorologist with the French meteorological service, said this early and exceptional heatwave would likely continue through the weekend. Eight departments in western France were placed on orange alert, the second of three levels. The Ministry of Sport urged extreme caution during exercise. Tragically, these conditions led to some real tragedies. On Sunday, a runner died in a race in Paris, and about 10 other runners were hospitalized in critical condition near the capital. A 28-year-old woman also died near Lyon from heatstroke caused by exertion during a combined running and aerobics event in an air-conditioned gym.
Exceptional measures to regulate work
To address these conditions, governments have begun implementing strict preventative measures. In Italy, on Monday, regulations came into effect in the Lazio region, which includes Rome, restricting work with prolonged sun exposure between 12:30 and 16:00. This measure, which was implemented last year starting May 30, will remain in place until September 15, reflecting the authorities' adaptation to the new climatic realities to protect workers and citizens from heatstroke and heat exhaustion.
