Figure subpanels
---------------------------------------------------
The figure has four panels. Each data file includes the panel letter immediately after the figure name.
---------------------------------------------------
List of data provided
---------------------------------------------------
This dataset contains long-term (2081–2100) projected annual mean changes (%) relative to present-day (1995–2014) in the SSP2-4.5 emissions scenario for:
- precipitation
- surface evapotranspiration
- total runoff
- surface soil moisture.
It also contains models agreement fraction on change sign.
All data combine time averages on observed period 1995-2014 and projection period 2081-2100.
The text file 'FigBoxTS-6-f1_md.txt' lists the metadata for the datasets, formatted as for the chapters data tables.

Using field separator '_', the second field is panel number, the third is the variable (pr = precipitation, evspsbl = evaporation, mrro = runoff, rsos = soil moisture), the fourth is the derived variable (either the relative change of ensemble means of the base variable, or fraction of models which agree on sign of change of the base variable). ANN stands for 'annual mean'
Two files are provided for each panel:
- the ensemble mean of the relative change of the corresponding variable, which shows in the figure using colours (*means*.nc)
- the fraction of models which agree on the sign of change, which shows in the figure using hatching, using the so called 'simple approach', described in AR6/WGI report Cross-Chapter Box Atlas.1 (*agreement*.nc)
---------------------------------------------------
Notes on reproducing the figure from the provided data
---------------------------------------------------
For reproducing the figures using a map drawing software, one needs to reproduce the color table shown in the figure and to hatch according to the so called 'simple approach', described in AR6/WGI report Cross-Chapter Box Atlas.1 (Link to the Atlas in the Related documents section of this catalogue record), and at https://interactive-atlas.ipcc.ch/regional-information/about#robustness. Basically : a hatching should show on regions where agreement is less than 80%

Process overview
| Title | Caption for Box TS.6, Figure 1 from the Technical Summary of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6) |
| Abstract | Projected water cycle changes. The intent of this figure is to give a geographical overview of changes in multiple components of the global water cycle using an intermediate emissions scenario. Important key message: without drastic reductions in greenhouse gas emissions, human-induced global warming will be associated with widespread changes in all components of the water cycle. Long-term (2081–2100) projected annual mean changes (%) relative to present-day (1995–2014) in the SSP2-4.5 emissions scenario for (a) precipitation, (b) surface evapotranspiration, (c) total runoff and (d) surface soil moisture. Numbers in top right of each panel indicate indicate the number of Coupled Model Intercomparison Project Phase 6 (CMIP6) models used for estimating the ensemble mean. For other scenarios, please refer to relevant figures in Chapter 8. Uncertainty is represented using the simple approach: No overlay indicates regions with high model agreement, where ≥80% of models agree on sign of change; diagonal lines indicate regions with low model agreement, where <80% of models agree on sign of change. For more information on the simple approach, please refer to the Cross-Chapter Box Atlas.1. {8.4.1; Figures 8.14, 8.17, 8.18, and 8.19} |
