title: Chapter 4 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 4.23 (v20230203)

description: Data for Figure 4.23 from Chapter 4 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 4.23 shows the projected long-term changes in seasonal mean relative humidity. --------------------------------------------------- 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: Lee, J.-Y., J.

DJF stands for December, January, February. JJA stands for June, July, August. CMIP6 is the sixth phase of the Coupled Model Intercomparison Project. SSP1-2.6 is based on Shared Socioeconomic Pathway SSP1 with low climate change mitigation and adaptation challenges and RCP2.6, a future pathway with a radiative forcing of 2.6 W/m2 in the year 2100. SSP3-7.0 is based on Shared Socioeconomic Pathway SSP3 which is characterized by high challenges to both mitigation and adaptation and RCP7.0, a future pathway with a radiative forcing of 7.0 W/m2 in the year 2100. --------------------------------------------------- Sources of additional information --------------------------------------------------- The following weblinks are provided in the Related Documents section of this catalogue record: - Link to the figure on the IPCC AR6 website - Link to the report component containing the figure (Chapter 4) - Link to the Supplementary Material for Chapter 4, which contains details on the input data used in Table 4.SM.1
