I think it is important to stress that with the current growth of fossil fuel
emissions we are above the
highest IPCC
emissions scenario (
RCP 8.5), at least for fossil fuel combustion.

Notably, future drought risk will likely exceed even the driest centuries of the Medieval Climate Anomaly (1100 - 1300 CE) in both moderate (
RCP 4.5) and
high (
RCP 8.5) future
emissions scenarios, leading to unprecedented drought conditions during the last millennium.
The WGI report is based on a new type of
scenarios of future anthropogenic
emissions called Representative Concentration Pathways (
RCPs), which include a mitigation
scenario leading to a very low climate forcing, two stabilization
scenarios and one
scenario with very
high GHG
emissions.
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).
The shading indicates a measure of uncertainty about future sea level for two different
scenarios — a low
emissions scenario where carbon
emissions are rapidly cut (blue
RCP 2.6) and a
high emissions scenario with no carbon cuts (red
RCP 8.5).
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.
While the
RCP CH4
emissions are within the ranges from the literature, there is a significant gap between
RCP2.6,
RCP4.5 and
RCP6 on the one hand and the
high -
emission RCP8.5
scenario on the other.
Figure that illustrates projected climate futures under a low
emissions (
RCP 2.6) and
high emissions (
RCP 8.5)
scenario, along with observed changes in climate change risks.
