Could PAINT be the answer to global warming? America's streets could soon be white as California pioneers 'cool pavements' to tackle the extreme heat effects of climate change

Los Angeles is slathering its streets in white sealant to combat the effects of climate change - and if it works, the rest of the US could be next.

California is pioneering the $150,000 scheme to cool down the blisteringly hot streets in August by by turning some of its streets white which can reduce temperatures by up to 15 degrees. 

The lighter 'cool pavements' and streets reflect as much as 30 to 50 percent of the sun's energy, compared to only 5 percent for new asphalt, and 10 to 20 percent for aged asphalt.
