Ashtangiman writes to tell us The New York Times is running an article about geoengineering in which many solutions to global warming include decreasing the amount of sunlight that the planet sees. The ideas are not new, many have been around for quite some time, however they have been relegated to the fringes of science and many have never been published because of this. From the article: "Geoengineering is no magic bullet, Dr. Cicerone said. But done correctly, he added, it will act like an insurance policy if the world one day faces a crisis of overheating, with repercussions like melting icecaps, droughts, famines, rising sea levels and coastal flooding."
