From the same publication:
Painting roofs white and creating lighter coloured pavements and roads are recognised as ways to reflect heat in urban areas and help combat global heating. However, a new study shows that this geoengineering technique unexpectedly causes temperatures to rise in the surrounding region.
We have hundreds of years of history where civilizations have concluded that white roofs are cooler. We have decades of modern academic research that backs that up.
One study indicating the opposite may be true in some cases is not sufficient evidence to start overturning legislation. It’s not enough to start submitting to the lobbying of these huge corporations trying to sell darker roofing materials. It IS enough to call for more research into the matter, and if enough research confirms this new finding THEN we start changing laws.
I cannot imagine any way that a dark roof would absorb less heat than a light roof. By definition a dark roof absorbs more light than a light roof, that’s why they appear dark/light.
I’d be interested in reading this one study though, if you have a link
Yes, dark colors absorb more heat. Trapping it and making the city hotter. Light colors reflect heat back, meaning the heat doesn’t stick around to heat up the area.
