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.
