Roofs painted with a white surface could better prepare London for heatwaves. READ MORE: BritsScientists already think that London is unprepared for hotter temperatures in a future hit by climate change.
Some of the world's whitest paints reflect nearly all sunlight, meaning buildings absorb less solar energy and in turn are cooler. 'We comprehensively tested multiple methods that cities like London could use to adapt to and mitigate warming temperatures,' he said.

Meanwhile, air conditioning – which transfers heat from within buildings to the outside – would warm London by about 0.27°F for the city overall, but by as much as 1.8F in dense central London. Cities generally trap heat, inducing the urban heat island effect that can lead to greater discomfort and death.
