title: Chapter 10 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 10.13 (v20220622)

description: Data for Figure 10.13 from Chapter 10 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 10.13 shows attribution of the southwestern North America precipitation decline during the 1983-2014 period. --------------------------------------------------- How to cite this dataset --------------------------------------------------- When citing this dataset, please include both the data citation below (under 'Citable as') and the following citation for the report component from which the figure originates: Doblas-Reyes, F.J., A.A.
