Removing C02 from the atmosphere is 'risky business'

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.

But a comment piece published today in Nature shows that most, if not all, of these methods pose environmental risks - and that much more research is needed before the wheels are set in motion on global-scale ‘climate geoengineering’ schemes.
