Fig. 3

Annual (left: 2010-2014 average) and cumulative (right: from 1751 to 2012) CO2-equivalent emissions under the GWP and GWP* metrics for selected regions, compared with the contributions of emissions from these regions to global temperature rise to 2012 (a, b, and d) and the rate of global temperature rise 2010–2014 (c) estimated using a simple climate model; see Methods. Solid diagonal lines show ratio of total global temperature rise (or rate of rise in c) to total global emissions under the metric shown. Dotted lines show best-fit regression lines under a logarithmic fit, with residuals about these lines given as root-mean-square fractional prediction errors. e, f Compare annual rates of emissions and cumulative emissions, respectively, under the two different metrics
