Can We Offset Global Warming By Geoengineering The Climate With Aerosols?

ScienceDaily (Feb. 22, 2008) — Concerned that energy system transformations are proceeding too slowly to avoid risks from dangerous human-induced climate change, many scientists are wondering whether geoengineering (the deliberate change of the Earth's climate) may help counteract global warming.

Every technology has had unexpected consequences.
We might find out to late that we have increased the risk of an earthquake.
I would also be concerned about processes that could cause the sudden release of the sequestered gases in the future, such as an asteroid strike. There was one big enough to get in the newspapers just a few months ago.
A sudden release of carbon dioxide in the ocean would cause a sudden increase in the acidity of the water, causing a massive die-off of shell-forming organisms.
