The numbers here relate to the IPCC's
lowest emissions scenario, RCP2
.6, which was specifically designed to show how warming can be limited to two degrees.
The radiative forcing estimates are based on the forcing of greenhouse gases and other forcing agents.5 The four selected RCPs were considered to be representative of the literature, and included one mitigation
scenario leading to a very
low forcing level (RCP2
.6), two medium stabilization
scenarios (RCP4.5 / RCP6) and one very high baseline
emission scenarios (RCP8.5).
In general, the
lowest emissions are found for the
scenario with the most stringent climate policy (RCP2
.6) and the highest for the
scenario without climate policy (RCP8.5), although this does not apply to all regions, at all times.
Projections from process - based models of global mean sea level (GMSL) rise relative to 1986 — 2005 as a function of time for two
scenarios — RCP2
.6, a
low emissions scenario, and RCP 8.5, a high
emissions scenario.
For the
lowest emissions scenario RCP2
.6 (which involves drastic
emissions reductions starting in a few years and leading to zero global
emissions by 2070, after that active removal of CO2 from the atmosphere) the best estimate sea - level rise by the year 2100 given by IPCC is 44 cm.
For the future, the IPCC projections for very high
emissions (red, RCP8.5
scenario) and very
low emissions (blue, RCP2
.6 scenario) are shown.
