Using geoengineering, the large-scale manipulation of the environment, to combat global warming has been proposed by scientists like Lowell Wood at Lawrence Livermore National Laboratory in California.
He argues that simulating a volcanic winter -- the cooling that follows major volcanic eruptions like Mount Pinatubo in 1991 -- is the most practical approach to managing global warming.
"It appears, of all the things I have heard discussed, to be the most economical and readily implemented," Wood says.
I watched a Nova program on global dimming due to particle pollution and thought to myself, if global warming ever got to a drastic level we could always just shoot sulfur particles up in the air. Looks like I am not the only one who has thought of this. This article is similar to the How to Cool the Planet Maybe article I blogged about a while back.

Update: Just found this article at Nature where Nobel laureate Paul Crutzen is suggesting injecting sulphate particles into the layer of atmosphere that starts about 10 kilometres above the ground.
