Over 2 billion in cities will be exposed to 0.5ºC rise by 2040

More than two billion people currently living in cities could be exposed to an additional temperature increase of at least 0.5 degrees Celsius by 2040, a new UN report published on Tuesday finds.

'Almost no urban resident will be unaffected, with billions of people subjected to hotter temperatures or exposed to the risks of flooding and other threats,' said Anacláudia Rossbach, Executive Director of UN-Habitat.
