Re:Geo-engineering a bad idea (Score 1)

Geo-engineering is the act of fighting pollution... with yet more pollution!

Some scientists have the notion that there has already been a significant reduction in sunlight from pollution. They think the clouds are made more reflective due to visible/particulate pollution. This could be partly masking the effects of global warming (they call it global dimming). Dr. Gerald Stanhill first came up with this notion in the 80's but no one believed him until several other scientists independently verified his results with similar measurements and with data from something called the "pan evaporation test."

It seems like we could end up with a dark, warm, armpit of a planet.

There is an awesome NOVA/PBS special on this.
