A persistent high-pressure heat dome is trapping heat and humidity over continental Europe, driving record temperatures from France to the UK. The phenomenon is linked to escalating temperatures due to fossil-fuel emissions, with authorities warning of health risks, wildfires, and rising energy demand.
The annual UK climate report shows that 2025 was the warmest year on record, with a shift of warmer conditions moving north and uphill. Days over 30C and nights over 18C have quadrupled in London, while rainfall fell sharply and droughts became more common. Authorities warn that extreme heat, sea levels, and water shortages will shape policy and daily life ahead.
