Talk about global warming quickly turns to the question of carbon in the atmosphere. But the more fundamental observation about how much sunshine the planet bounces back into space should probably precede any mention of greenhouse gases.
A new study quantifies the true beauty of white roofs — dramatically cooler surfaces that reduce discomfort, cooling costs, and a tad of global warming.
The loss of sea ice is a concern for more than polar bears, as the loss of reflectivity it represents means the planet may warm even faster.
The U.S. government opts takes an easy step toward reducing — in a small way — global warming and energy use.
Even partisans of using reflective roofs note that a 'winter penalty' in cooler climes may mean their albedo benefits could pale compared to heating requirements.
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.
