Global Warming: Time for Plan B?

The Independent has an interesting article about how many leading scientists feel that more proactive solutions to the increasing CO2 levels are, or may become, necessary. They cite both the failure so far to cut emissions, and a decreasing capacity of the Earth to absorb CO2 on its own.

Their "geoengineering" notions include putting sunlight-reflecting particles into the atmosphere in emulation of natural volcanic processes, pumping water vapor into the air above the ocean to form reflecting clouds, boosting the population of CO2-consuming phytoplankton by seeding the ocean with iron filings, circulating the water of the oceans to sink CO2 out of the normal carbon cycle, and deflecting sunlight with huge mirrors in space.
