• UK ‘built for climate that no longer exists’ and needs urgent changes to survive global heating, report warns

It may not always feel like it, but Britons are going to have to get used to living in a hot country.

Temperatures are already 1.4C above the historic norm, and heading for a 2C rise in the next two decades. This may not sound like much, but it will mean far higher temperatures in summer – heatwaves as high as 45C lasting for more than a week, dwarfing the previous record of 40C in 2022 – as well as more frequent droughts and severe flooding, according to a major report published on Wednesday.
