Scientists call it "geoengineering," but in plain speak, it means things like this: blasting tons of sulfate particles into the sky to reflect sunlight away from Earth; filling the ocean with iron filings to grow plankton that will suck up carbon; even dimming sunlight with space shades.
Each brings its own set of risks, but in a world fretting about the consequences of global warming, are these ideas whose time has come?
