Steven Chu, President Obama’s science adviser, has suggested that it might be a good idea to encourage people to paint their roofs white– and thus reflect solar radiation back into space, helping to save us from the peril of global warming. Here’s a story on the proposal in the British Telegraph newspaper.
I remember that in the 1970s, when there was a scare about future “global cooling”, there were proposals to sprinkle black carbon particles on arctic ice, thus having the opposite effect: absorb more radiation and protect us from the coming Ice Age. Of course that scare didn’t last nearly as long as the current concern about excessive warming.
I can’t help thinking about the Disney “Alice in Wonderland” movie, in which the Red Queen’s gardeners try to remedy a horticultural mistake by “painting the roses red”.
Well, I know this is different– after all, Dr. Chu won the Nobel prize in physics. In the movie, her majesty was not amused and shouted: “Off with their heads!”
