The hearing, titled "Climate Science: Assumptions, Policy Implications, and the Scientific Method," will "examine the scientific method and process as it relates to climate change" and "focus on the underlying science that helps inform policy decisions," according to a hearing charter.
Although a few previous studies have assessed O3 health impacts under climate change assumptions, none have used global-to-regional downscaled climate models to project O3 concentrations for health impacts assessment.
Although the storm risk model does not predict windthrow probability climate-sensitively, assumptions on the frequency and intensity of storm events under climate scenarios alter the interpretation when transferring vulnerability probabilities into damages and losses.
However, hydroelectricity developments are large, complicated projects and possibly critically vulnerable to changes in climate and other assumptions related to future uncertainties.
The impacts of different stocking densities on the environment were assessed through a set of simulation experiments for various combinations of climate input and assumptions about the development of livestock numbers.
One subject-matter expert scored cold-related mortality at 'ambiguous sign/trend', suggesting that it could increase, rather than decrease, under some climate scenarios and assumptions on autonomous adaptation, although only one study [ 25] has demonstrated this.
In some cases, however, as a result of land-use and/or climate change, this assumption is no longer valid.
The SIVM provides substantial improvement over specified vegetation assumptions in climate models and aids in the interpretation of past climates.
Mr Pindyck calls the models' assumptions about climate damage "completely made up".Lord Stern argues that their treatment of growth is not much better.
Realclimate will emphasize the very tentative nature of this forecast, and caution that there is a danger that if one doesn't fully realize how doubtful some of the assumptions are, climate modelers may well be slammed with the accusation that "they predicted a cooling but it didn't happen".
