Co-author Professor Phil Ineson, from the University of York, said: "Computer climate models have become increasingly complex and I wanted to go back to basics. We achieved this by somewhat radically building a 'physical' model of the terrestrial carbon cycle – this is equivalent to using a wind tunnel (as opposed to a computer simulation) to test the aerodynamics of a new structure. Our experimental findings made total sense but suggested that the capacity of the Earth to buffer against rising carbon dioxide may be gre ater than the computer models imply – we still have the same major concerns about climate change , but the Earth system may ha ve some tricks up her sleeve!"
