From this experiment we hoped to achieve a better understanding of the range of uncertainty in climate models due to the parameters in the sulphur cycle.

Not exact matches

Much of the uncertainty in projections of global climate change is due to the complexity of clouds, aerosols, and cloud - aerosol interactions, and the difficulty of incorporating this information into climate models.

Due to the complexity of physical processes, climate models have uncertainties in global temperature prediction.

Furthermore, all approaches that use the climate's time evolution attempt to account for uncertainty due to internal climate variability, either by bootstrapping (Andronova and Schlesinger, 2001), by using a noise model in fingerprint studies whose results are used (Frame et al., 2005) or directly (Forest et al., 2002, 2006).

So, of course there are uncertainties in the findings, as in any attribution and detection result, there is a remaining chance that the observed change is due to internal climate variability (5 - ish %) particularly if the models would underestimate that variability.

In addition, there are numerous uncertainties in the climate models themselves, due to the challenge of numerically simulating all relevant aspects of the climate system over long timescales of decades to centurieIn addition, there are numerous uncertainties in the climate models themselves, due to the challenge of numerically simulating all relevant aspects of the climate system over long timescales of decades to centuriein the climate models themselves, due to the challenge of numerically simulating all relevant aspects of the climate system over long timescales of decades to centuries.

Lyman and colleagues combined different ocean monitoring groups» data sets, taking into account different sources of bias and uncertainty — due to researchers using different instruments, the lack of instrument coverage in the ocean, and different ways of analyzing data used among research groups — and put forth a warming rate estimate for the upper ocean that it is more useful in climate models.

These NAO «book - ends» provide an estimate of the 5 — 95 % range of uncertainty in projected trends due to internal variability of the NAO based on observations superimposed upon model estimates of human - induced climate change.

The aim of this project is to examine much more exhaustively than has previously been possible the climate uncertainties due to uncertainties in how to model land surface effects.

If one uses the historical record of warming to help tune your climate model, you are assuming that 100 % of warming is due to the forcing we know about (with a great deal of uncertainty in the case of aerosols).

Uncertainties in forcings and in climate models» temperature responses to individual forcings and difficulty in distinguishing the patterns of temperature response due to GHGs and other anthropogenic forcings prevent a more precise quantification of the temperature changes attributable to GHGs.
