>I think it's weird that people react so negatively to geoengineering when the status quo is that we're changing the climate adversely just by thoughtless inaction with respect to reducing CO2 emissions. One of the problems with deliberate geoengineering, as opposed to accidental geoengineering (CO2 release), is that it's a lot easier to assign responsibility. There will be countries that benefit from climate change. Particularly likely cases include Russia, where winters become milder and growing seasons longer, and Saudi Arabia, where precipitation will significantly increase. There will also be major losers, like Mexico, where precipitation will decline and coastal heat will become lethal. In addition, there will probably be countries disproportionately affected by the side-effects of geoengineering. Decreased sunlight will affect agriculture — the largest players being US, India, China — and sulfur deposition likely will as well. The world can hardly agree on such obvious necessities as "don't catch all the fish in the ocean".
