London could feel as hot as Barcelona by 2050, with Edinburgh's climate more like Paris, Leeds feeling like Melbourne and Cardiff like Montevideo.
That's from a study looking at how a 2C temperature increase could change the world's 520 major cities.
And that's not as good as it might sound.
More than a fifth, including Singapore and Kuala Lumpur, will experience conditions big cities haven't seen before, the Crowther Lab says.
London could suffer from the type of extreme drought that hit Barcelona in 2008 - when it was forced to import drinking water from France at a cost of £20 million.
