«The precise parameters of the U.K.'s future relationship with the European Union remained highly uncertain and it seemed likely that asset prices would remain sensitive to perceived developments in the outlook in the months ahead,» the Bank of England said through the minutes of the policy committee's meeting.

Although estimates of this parameter, based on observations, are very uncertain, observers generally quote values in the range from 50 to 90 kilometres per second per megaparsec.

In that survey, it was almost universal that groups tuned for radiation balance at the top of the atmosphere (usually by adjusting uncertain cloud parameters), but there is a split on pratices like using flux corrections (2 / 3rds of groups disagreed with that).

Typically there is also a single parameter controlling the rate of ocean heat uptake, and forcings (from aerosols in particular, this forcing being quite uncertain) can of course readily be adjusted.

It is pretty clear that the model for the process governing Sun spot occurrence is the correct one, even if the parameterization is somewhat statistically uncertain (and even if some parameters may be randomly or deterministically varying slowly and / or narrowly in time, as well as the precise frequency distribution of noise energy, though we really only care about that within a narrow band around the resonances).

In perturbed physics projections, «a single model structure is used and perturbations are made to uncertain physical parameters within that structure...» [5] That is, a perturbed physics experiment shows the variation in climate projections as model parameters are varied step-wise across their physical uncertaintIn perturbed physics projections, «a single model structure is used and perturbations are made to uncertain physical parameters within that structure...» [5] That is, a perturbed physics experiment shows the variation in climate projections as model parameters are varied step-wise across their physical uncertaintin climate projections as model parameters are varied step-wise across their physical uncertainty.

Because of the sensitivity of the shelter level temperature to parameters and forcing, especially to uncertain turbulence parameterization in the SNBL, there should be caution about the use of minimum temperatures as a diagnostic global warming metric in either observations or models.»

Climate IAMs have «hundreds of input parameters, each of which is highly uncertain in the long run.»

In UKCIP08, for example, we are handling this problem by combining results from two different types of ensemble data: One is a systematic sampling of the uncertainties in a single model, obtained by changing uncertain parameters that control the climate system; the other is a multi-model ensemble obtained by pooling results from alternative models developed at different international centerIn UKCIP08, for example, we are handling this problem by combining results from two different types of ensemble data: One is a systematic sampling of the uncertainties in a single model, obtained by changing uncertain parameters that control the climate system; the other is a multi-model ensemble obtained by pooling results from alternative models developed at different international centerin a single model, obtained by changing uncertain parameters that control the climate system; the other is a multi-model ensemble obtained by pooling results from alternative models developed at different international centers.

Even the most fundamental quantitative parameter of all, the forcing factor relating the increase in mean temperature to a doubling of CO2, lies somewhere between 1 and 3 degrees, and is thus uncertain to within a factor of 3.

Lastly, while there are wide variations in plausible scenarios around the future of the homeownership rate, they require many uncertain parameters, which makes it difficult to say with much confidence how the homeownership rate will evolve.
