Professor Flannery: emissions trading insufficient, world needs biological means to scrub CO2 out of atmosphere

A few days ago some of the world’s leading climate scientists wrote that we need to be far more active in cutting carbon emissions, urgently. Currently, atmospheric CO2 levels are at 383ppm and we need to go back to 350ppm if we want to keep the planet liveable. This implies a range of technologies that actively remove CO2 from the atmosphere, such as biochar, reforestation and carbon-negative bioenergy (i.e. biomass coupled to CCS). Now professor Tim Flannery, chairman of the Copenhagen Climate Council and the Australian equivalent of Al Gore, joins in saying we must use biological means to tackle a crisis that could otherwise end in a catastrophe much earlier than expected.
