Wilderness Arson and the Greenhouse Effect

Some GIS folks have postulated that "small scale" nuclear winter would alleviate pressure, allowing for global warming but not of a greenhouse variety. These same people have postulated that large scale forest fires would have the same effect. Somehow, somewhere someone seems to be postulating that global desertification is prefferable to greenhouse warming. Could it be the privatizers of water? Too bad they won't consider lessening resource consumption.
