CMIP6 is the sixth phase of the Coupled Model Intercomparison Project. CORDEX is Coordinated Regional Downscaling Experiment from the WCRP. WCRP is the World Climate Research Programme. SSP stands for Shared Socioeconomic Pathway. SSP126 is the Shared Socioeconomic Pathway which represents the lower boundary of radiative forcing and development scenarios, consistent with RCP2.6. SSP585 is the Shared Socioeconomic Pathway which represents the upper boundary of radiative forcing and development scenarios, consistent with RCP8.5. RCP stands for Representative Concentration Pathway. RCP2.6 is the Representative Concentration Pathway for 2.6 Wm-2 global warming by 2100. RCP8.5 is the Representative Concentration Pathway for 8.5 Wm-2 global warming by 2100. --------------------------------------------------- Notes on reproducing the figure from the provided data --------------------------------------------------- For panel a, the plotting script (see data tables and code on Github) draws the rivers and uses a subroutine to identify the rivers to plot them individually with lines; plotting the Q100 netcdf file will produce dots (and not rivers). For panel c, the recent past values are plotted as absolute values (left column on each regional subpanel) and the future changes are plotted as differences against the recent past values (differences are computed when plotting the values). --------------------------------------------------- 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 12) - Link to the Supplementary Material for Chapter 12, which contains details on the input data used in Table 12.SM.1 - Link to the code for the figure, archived on Zenodo - Link to the Chapter 12GitHub repository Servonnat, Jérôme Unavailable author Unavailable author Iles, Carley Unavailable author Unavailable author NERC EDS Centre for Environmental Data Analysis custodian 01235446432 RAL Space STFC Rutherford Appleton Laboratory, Harwell Campus Didcot OX11 0QX United Kingdom support@ceda.ac.uk custodian NERC EDS Centre for Environmental Data Analysis distributor 01235446432 RAL Space STFC Rutherford Appleton Laboratory, Harwell Campus Didcot OX11 0QX United Kingdom support@ceda.ac.uk distributor NERC EDS Centre for Environmental Data Analysis point_of_contact 01235446432 RAL Space STFC Rutherford Appleton Laboratory, Harwell Campus Didcot OX11 0QX United Kingdom support@ceda.ac.uk pointofContact NERC EDS Centre for Environmental Data Analysis publisher 01235446432 RAL Space STFC Rutherford Appleton Laboratory, Harwell Campus Didcot OX11 0QX United Kingdom support@ceda.ac.uk publisher unknown dataset IPCC-DDC IPCC AR6 WG1 WGI Sixth Assessment Report Working Group 1 Physical Science Basis South-America Central-America regional river discharge extreme shoreline position CMIP6 CMIP5 CORDEX global warming levels GWL +1.5°C +2°C +4°C ssp126 ssp585 recent past mid-term long-term 1995-2014 2041-2060 2081-2100 RCP4.5 RCP8.5 atmospheric conditions theme GEMET - INSPIRE themes, version 1.0 2008-06-01 publication otherRestrictions Public data: access to these data is available to both registered and non-registered users. otherRestrictions Under the following licence http://creativecommons.org/licenses/by/4.0/, appropriate use of these data may fall under any use.
