The UN climate chief, Simon Stiell, describes a record-breaking early heatwave across western Europe as “a brutal reminder” of the climate crisis’s growing impacts. Multiple outlets report that the UK and France record their hottest-ever May days this week, with a “heat dome” pushing temperatures more typical of midsummer into the region. Stiell says the “main culprit” is humanity’s burning of coal, oil and gas, which drives climate change, and he adds that human-induced warming is making heatwaves more frequent and extreme.

Reports also link the broader context of extreme heat beyond Europe. Authorities in India face forest fires and local reports of deaths from heatstroke, while air-quality monitoring data show many of the world’s hottest cities at midday on the day referenced. Several sources note reported heat-related fatalities in France and drownings associated with people seeking relief in water, and record high temperatures in other European countries including Ireland, along with unusually hot conditions in parts of Spain, Italy and Austria.
