From: Pathways for balancing CO2 emissions and sinks

Figure 6

(a) Atmospheric carbon concentration (p.p.m.), shown with CDIAC data33 and RCP projections7; (b) cumulative anthropogenic emissions (2001–2100) [PgC], compared with historical emissions (IPCC3 and FeliX) and RCP projections. (c) Total radiative forcing (W m−2) for all greenhouse gases, shown with CDIAC data and RCP projections. CO2 forcing is modelled endogenously; all other greenhouse gases are exogenously set to RCP 4.5. (d) Global average surface temperature change relative to preindustrial (ΔT) (°C). Historical time series from HadCRUT4 (ref. 38). ΔT projections associated with each of the RCPs in 2100 are shown at right with 90% confidence intervals40.
