A new framework for climate
scenarios research brings an integrated view of economics, demography, and greenhouse gas
emissions to the development of
emissions scenarios that
underlie climate models.
Especially if you are versed in the
underlying science, you'll see that it presents two kinds of uncertainties — those inherent in climate models, and those in the
emission scenarios that are fed into the models.
The
underlying integrated assessment model outputs for land use, atmospheric
emissions and concentration data were harmonized across models and
scenarios to ensure consistency with historical observations while preserving individual
scenario trends.
Representative Concentration Pathways, are referred to as pathways in order to emphasize that they are not definitive
scenarios, but rather internally consistent sets of time - dependent forcing projections that could potentially be realized with more than one
underlying socioeconomic
scenario... They are representative in that they are one of several different
scenarios, sampling the full range of published
scenarios (including mitigation
scenarios) at the time they were defined, that have similar RF and
emissions characteristics.

underlying world oil prices are below $ 90 per barrel during the next two decades, then none of the policy
scenarios modeled achieves the desired targets for annual U.S. CO2
emissions.
The 40 SRES
scenarios cover the full range of GHG and SO2
emissions consistent with the storylines and
underlying ranges of driving forces from studies in the literature as documented in the SRES database.
