Panel (c) data can be computed from panel (b) data so are not provided here. --------------------------------------------------- List of data provided --------------------------------------------------- The dataset contains global time-series data from 1960-2100 for: - Observed global temperature change (1960-2017). - Historical anthropogenic global warming (1960-2017). - Modelled warming responses to global emission and radiative forcing pathways (2018-2100). The dataset also contains global time-series data for carbon dioxide (CO2) and non-CO2 radiative forcing from 1960-2100 for: - Historical global net CO2 emissions (1960-2017). - Stylized global net CO2 emission pathways (2018-2100). - Historical global cumulative net CO2 emissions (1960-2017). - Stylized global cumulative net CO2 emission pathways (1960-2100). - Historical global non-CO2 radiative forcing pathways (1960-2017). - Global non-CO2 radiative forcing pathways (2018-2100). --------------------------------------------------- Data provided in relation to figure --------------------------------------------------- Panel a: - Data file: panel_a/temps_hist.csv (monthly data, 1850-2017); relates to the left part showing observed global mean surface temperature change (grey line) and estimated anthropogenic global warming (orange line with shading the assessed likely range). - Data files: panel_a/temps_blue.csv, panel_a/temps_grey.csv, panel_a/temps_purple.csv (yearly data, 2018-2100, the lower and upper bound variables are plotted). These relate to the right part showing the likely range of warming responses (grey, blue and purple plumes) for different combinations of global net CO2 emission and net non-CO2 radiative forcing pathways. Panel b: - Data file: panel_b/gcp_out.csv (yearly data, 1960-2017); relates to the left part showing historical global net CO2 emissions (grey line). - Data file: panel_b/CO2_ems.csv (yearly data, 2018-2100, values in GtC rather than GtCO2); relates to the right part showing two stylized future global net CO2 emission pathways (grey land blue lines). Panel d: - Data file: panel_d/nonCO2_RF.csv (yearly data, 1960-2017, variable nonCO2RF_grey is plotted); relates to the left part showing historical global net non-CO2 radiative forcing. - Data file: panel_d/nonCO2_RF.csv (yearly data, 2018-2100, variables nonCO2RF_grey and nonCO2RF_purple are plotted); relates to the right part showing two stylized future global net non-CO2 radiative forcing pathways (grey and purple lines).
