…although it may seem almost comically straightforward, one of the best temperature-reducing approaches is very simple: paint things white. Cities have a lot of black asphalt and dark, heat-absorbing structures. By increasing reflection and shade, a great deal of heat build-up can be avoided. Paint most of a city and you could lower the temperature by 10C.
Professor Steven Chu, speaking at the opening of the St James’s Palace Nobel Laureate Symposium, for which The Times is media partner, said this simple and “completely benign” approach to “geo-engineering” could have a vast impact at low cost. By lightening all paved surfaces and roofs to the colour of cement, it would be possible to reduce carbon emissions by as much as taking all the world’s cars off the roads for 11 years, he said.
I ask you to compare and contrast because one of these men is an “evil delayer” (or worse), and the other a planetary savior. Yet the savior is now adopting a policy advocated for two years by the “delayer.”
Perhaps there is hope for the global warming debate yet.
