ScenarioMIP (O’Neill et al., 2016) |
ssp126 |
2015 - 2100 |
A high
ambition scenario designed to produce significantly less than 2 degrees
warming by 2100. |
|
ssp245 |
2015 - 2100 |
Designed to represent a medium forcing future
scenario. This is the test scenario to be held back for
evaluation |
|
ssp370 |
2015 - 2100 |
A medium-high forcing scenario with high
emissions of near-term climate forcers (NTCF) such as methane and
aerosol. |
|
ssp370-lowNTCF |
2015 - 2054 |
Variation of SSP370 with lower
emissions of aerosol and their precursors |
|
ssp585 |
2015 - 2100 |
This scenario represents the high end of the
range of future pathways in the IAM literature and leads to a very large
forcing of 8.5 Wm-2 in 2100. |
CMIP6 (Eyring et al., 2016) |
historical |
1850 – 2014 |
A simulation
using historical emissions of all forcing agents designed to recreate
the historically observed climate. |
|
abrupt-4xCO2 |
500 years |
Idealised simulation in which CO2 is
abruptly quadrupled. Other forcing agents remain
unchanged. |
|
1pctCO2 |
150 years |
Idealised simulation in which CO2 is gradually
increased by 1% / year. Other forcing agents remain
unchanged. |
|
piControl |
500 years |
Baseline simulation in which all forcing
agents remain unchanged. |
DAMIP (Gillett et al., 2016) |
hist-GHG |
1850 – 2014 |
A historical
simulation with varying concentrations for CO2 and other long-lived
greenhouse-gases (only). |
|
hist-aer |
1850 – 2014 |
A historical simulation only forced by
changes in anthropogenic aerosol. |
