A heat dome is affecting Western Europe, causing high temperatures. Experts have linked the extreme heat conditions to climate change.

Temperatures in Western Europe were above the average for May, according to the BBC. Several hundred cities in the region broke all‑time May heat records, reported by Bluesky. The early heat wave in Europe broke records and caused deaths, according to DW. France 24 reported that the heat‑dome phenomenon is being exacerbated by climate change. The Guardian noted that the heat dome shattered temperature records for May in the United Kingdom and Ireland. Nukta.com reported that Western Europe recorded its hottest June on record, and the Hindu cited Copernicus as saying June was the second hottest June on record for the world and for Europe. Nukta.com also reported that average temperatures in June were more than 3 °C above the 1991‑2020 norm, breaking the previous record set in June 2025. The Times of India described temperatures rising toward 40 °C, prompting health alerts and transport chaos; Italy issued red alerts for eight cities, France faced rail disruptions, and wildlife was under immense pressure.
