In Fig. 2c and d of this Letter, the case of ‘Delayed action until 2020’ under an intermediate level of future energy demand (green dashed line) previously contained an inconsistency in its evolution of global greenhouse gas emissions until 2020 (that is, its greenhouse gas emissions until 2020 were in line with the low-energy instead of the intermediate-energy demand case). This resulted in lower cumulative emissions and, hence, relatively higher probabilities of staying below a particular global-mean temperature threshold than what would otherwise be consistent with the intermediate-energy demand case in Table 1. Figure 2 has been corrected in the HTML and PDF versions of the Letter online. In addition, data for the corrected case (‘Delayed action until 2020’) have been updated accordingly in Supplementary Figs 2, 3, 4, 5, 8 and 9, and the Supplementary Data. None of these changes affect our results or conclusions.
