Three California energy experts make a convincing -- and sincere -- case that painting roofs white in the hot parts of the planet could offset the greenhouse gas woes caused by the world's cars
The co-author of A Golden Thread: 2500 Years of Solar Architecture and Technology takes a look at how white backgrounds — be they snow, concrete or rooftops — might help bend back a little bit of global warming.
