Yes, I’d read of idea to paint roofs white. From the Guardian:
Quote:
Should we paint the world white to tackle the impact of global warming? Hashem Akbari, a scientist at Lawrence Berkeley National Lab in California thinks so, and is launching a worldwide campaign to brighten up our cities. Turn enough rooftops and roads a whiter shade of pale, he says, and enough extra sunlight will be bounced back into space to cool the planet.
It won’t solve the problem of climate change
