Climate models incorporate several scenarios that are based on a range of emission scenarios

RCP8.5: This RCP is characterized by increasing greenhouse gas emissions over time, representative of scenarios in the literature that lead to high greenhouse gas concentration levels.

RCP6: This RCP represents a stabilization scenario where total radiative forcing is stabilized shortly after 2100, through the application of a range of technologies and strategies that reduce greenhouse gas emissions.

RCP4.5: This RCP is another stabilization scenario where total radiative forcing is stabilized shortly after 2100, without overshooting the long-run radiative forcing target level (emissions restrictions are tighter than for RCP6).

RCP2.6: This emission pathway is modeled using very low greenhouse gas concentration levels. In order to reach low radiative forcings (2.6 W/m2 by 2100), greenhouse gas emissions are reduced substantially over time.
