Geo-engineering 'a risk' in climate change battle


Geo-engineering 'a risk' in climate change battle: The report divides geo-engineering solutions to climate change into two basic types - plans to suck carbon dioxide out of the atmosphere and plans to block some of the sun's heat before it gets here.

They include fertilising the oceans with iron filings, to stimulate the growth of algae, which absorbs CO2 and then sinks to the ocean floor, and sowing the atmosphere with sulphates, which deflect some of the sun's rays away from Earth.
