Two papers published in a recent issue of Nautre tell us how much CO2 we can afford to pump into the atmosphere to make it likely for us to stay within 2C average global warming. The findings have dramatic implications for national and international climate policy. We speak to one of the paper’s lead authors, Myles Allen of the Climate Dynamics team, University of Oxford.
