Dataset regarding the « Reasons for concern » about climate change from figures in IPCC and related publications

This data corresponds to the 'burning ember' diagrams from IPCC reports and related publications (IPCC TAR, Smith et al. 2009 for AR4-related embers, AR5 and SR15). It was used to build figure 3 of Zommers et al. 2020 (Burning Embers: Towards more transparent and robust climate change risk assessments. Accepted for publication in Nature Reviews Earth & Environment). The data provided here is the result of extraction of information from the original figures, as presented in the related technical document 10.5281/zenodo.3992856. As explained in the Supplementary Information of Zommers et al. 2020 and the technical document, this is not data from the IPCC. The provided values are approximations of the global mean temperature increase corresponding to each change in risk in the original diagrams. The rigour of the preparation process and the limitations of the dataset are explained in the technical document.Version 2 (r2) of this file contains the same data as the first version but in a different file format. Both describe exactly the same information and can be used to produce exactly the same diagram (with e.g. https://climrisk.org/emberfactory
