Metadata provided for all the plots in the figure, and data is provided for the maps of surface temperature (projections and 2020) and for the atmospheric CO2 concentration corresponding to the paleo 60 - 1 million years time series, and paleo and direct measurements from 800 thousand years to 1980. --------------------------------------------------- List of data provided --------------------------------------------------- This dataset contains: - Atmospherics CO2 concentration (ppm) corresponding to the paleo 60–1 million years - Atmospherics CO2 concentration (ppm), paleo and direct measurements from 800 thousand years to 1980 - Global surface temperature for 2020 (estimate of the total observed warming since 1850–1900). - Global surface temperature at 2100 and 2300 from CMIP6 models (relative to 1850-1900) for SSP1-2.6 and SSP5-8.5 scenarios. --------------------------------------------------- Data provided in relation to figure --------------------------------------------------- - Data file: CO2_60_Myr.csv (top row, atmospheric CO2 concentration corresponding to the paleo 60–10 million years time series) - Data file: fig2_4a_main_figure_data.csv (top row, paleo and direct measurements from 800 thousand years to 1980) - Data file: TS_BK_2020.nc (Global surface temperature map for 2020, estimate of the total observed warming since 1850–1900). - Data file: ensmean_tas_ssp126_2100-historical_1850_regrid.nc (Global surface temperature map at 2100 relative to 1850-1900 for SSP1-2.6 scenario) - Data file: ensmean_tas_ssp126_2300-historical_1850_regrid.nc (Global surface temperature map at 2300 relative to 1850-1900 for SSP1-2.6 scenario) - Data file: ensmean_tas_ssp585_2100-historical_1850_regrid.nc (Global surface temperature map at 2100 relative to 1850-1900 for SSP5-8.5 scenario) - Data file: ensmean_tas_ssp585_2300-historical_1850_regrid.nc (Global surface temperature map at 2300 relative to 1850-1900 for SSP5-8.5 scenario) CSV files were converted for archival from Excel workbooks. SSP stands for Shared Socioeconomic Pathway. ppm stands for parts per million. 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. SSP2-4.5 is based on Shared Socioeconomic Pathway SSP2 with medium challenges to climate change mitigation and adaptation and RCP4.5, a future pathway with a radiative forcing of 4.5 W/m2 in the year 2100. SSP5-8.5 is based on Shares Socioeconomic Pathway SSP5 where climate change mitigation challenges dominate and RCP8.5, a future pathway with a radiative forcing of 8.5 W/m2 in the year 2100. --------------------------------------------------- Temporal Range of Paleoclimate Data --------------------------------------------------- This dataset covers a paleoclimate timespan from 60 Myr to 2300. Myr refers to millions of years before present. --------------------------------------------------- Notes on reproducing the figure from the provided data --------------------------------------------------- Notes on reproducing this figure are linked in a computation record found in the Process section of this catalogue record. --------------------------------------------------- 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 (Technical Summary) - Links to the report components of the underlying chapter figures from which part of this figure was generated (Chapter 2 and Chapter 7) - Link to the Supplementary Material for Chapter 2, which contains details on the input data used in the figure - Link to the Supplementary Material for Chapter 7, which contains details on the input data used in the figure - Link to the data for 2300 emissions scenarios described in section 4.7, archived on Zenodo. - Link to the data for 2300 projections from Figure 4.40a (section 4.7.1), archived on Zenodo.
