Radical carbon dioxide removal projects could be a risky business -- ScienceDaily

Radical new ways of removing CO2 from the atmosphere could prove to be a risky business -- according to an environmental scientist at the University of East Anglia. Techniques put forward include growing crops to be burned in power stations, large-scale tree plantations, adding biochar to soil, adding nutrients to sea water to boost plankton and seaweed, and using chemicals to extract CO2 from the atmosphere -- to be buried deep underground.
