A new study in Nature says that the global uptake of carbon by land plants may be up to 45 per cent more than previously thought.
From the media release:
Instead of 120 petagrams of carbon, the annual global vegetation uptake probably lies between 150 and 175 petagrams of carbon. This value is a kind of gross national product for land plants and indicates how productive the biosphere of the Earth is. The reworking of this so-called global primary productivity would have significant consequences for the coupled carbon cycle-climate model used in climate research to predict future climate change.
For how this could affect global warming alarmism, check out the IPCC’s Fourth Assessment Report on Coupled Climate-Carbon Cycle Projections.
