Climate engineering, or what I call Operation Sunscreen, would mean trying to alter the heat absorption properties of the atmosphere. The goal might be to reduce average temperatures by, say, 2 degrees centigrade.

I have no idea how to reduce heat absorption, but one can imagine a number of possible approaches to climate engineering: putting reflectors out into space; using some physical or chemical process to "wash" carbon out of the atmosphere; or coming up with a way to reduce concentrations of water vapor (the most abundant greenhouse gas) in the atmosphere.

Personally I've always favored the idea of a giant flatscreen TV to solve global warming. It'd be kinda like this, except way cooler since it'd keep the earth cool during the day and at night we could watch movies on it. Except Thursday nights when under international law we'd have to show Bollywood movies.
