Tackling reduction of carbon dioxide pollution is proving difficult to do, although much of this is political intransigence. Peter Cox Professor of Climate System Dynamics and leader of the inter-disciplinary "Climate Change and Sustainable Futures" activity at the University of Exeter, suggests we should come at the problem from a different angle - focusing at first in reducing methane emissions which would allow a greater CO2 budget to keep within. Buying us some time.
"It looks extremely unlikely that we can stop global warming at 2 °C just by reducing CO2 emissions," he told New Scientist in March 2012. "That probably requires peaking emissions by 2020. But drastic action on methane would make the task much more feasible."
