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.

The 2C rise by 2050 is comparing the present day to what temperatures were in the “pre-industrial period” – usually considered to be between the years 1850 and 1900 – when fossil-fuel burning hadn’t yet changed the climate.

That temperature increase would result in the average UK temperature during summer’s hottest month increasing by about six degrees to 27C.

Scientists hope pairing up cities will help people visualise the impact climate change could have within their own lifetimes.

“History has repeatedly shown us that data and facts alone do not inspire humans to change their beliefs or act,” lead author Jean-Francois Bastin said.

The study, published in the journal PLOS One, suggests summers and winters in Europe will get warmer, with average increases of 3.5C and 4.7C respectively.

It’s the equivalent to a city shifting 620 miles (1,000km) further south – with those furthest away from the equator being most affected.
