Shading the Earth http://apocadocs.com/s.pl?1247854767
Some call it hubris; others call it cool reason. But the idea that we might combat global warming by deliberately engineering a cooler climate -- for instance, by constructing some kind of planetary sunshade -- has lately migrated from the fringe to the scientific mainstream. We are already modifying climate by accident, say proponents of geoengineering; why not do something intentional and intelligent to stop it? "If a country starts thinking it's in their vital interests to do this, and they have the power, I find it hard to imagine them not doing it," says Ken Caldeira, a climate expert at the Carnegie Institution. Caldeira is talking about the easiest, cheapest form of geoengineering: building a sunshade in the stratosphere out of millions of tons of tiny reflective particles, such as sulfate.
