neither do those uncertainties allow scientific closure — as long as models of the climate system's behavior decay into chaos on shorter time scales than human history, climate modeling will remain prey to misrepresentation by those well enough paid, or ideologically bloody minded enough to do so: the trouble with the climate wars is that neither political side, activist or obscurantist, really gives a damn about the science, and those presuming to speak for it invite damnation by both.

The interannual variability in the individual simulations that is evident in Figure 9.5 suggests that current models generally simulate large - scale natural internal variability quite well, and also capture the cooling associated with volcanic eruptions on shorter time scales.

I don't have >> the paper to hand, but I think it is... >> >> Wigley, T.M.L., Huckstep, N.J., Mortimer, R., Farmer, G., Jones, P.D., >> Salinger, M.J. and Ogilvie, A.E.J., 1981: The reconstruction of European >> climate on decadal and shorter time scales.

For many people in India it is the variability of rainfall on shorter time scales that has the biggest impacts — intense heavy rainfall leads to flooding; breaks in the monsoon of a week or more lead to water shortage and agricultural drought.

That means that the potential for natural variability to be more dominant on shorter time scales is high — and indeed, Connolley and Bracegirdle show a lot of variance in the model output on those time scales.

It is these uppermost few percent of events that are important, and models and theory are nearly unanimous now that they are and will continue to increase, notwithstanding natural climate variability on shorter time scales (as much as 20 years).»

[Response: Red noise is produced by a kind of stochastic process that has more variability at longer time scales than at shorter time scales.

Climate change involves time scales of many years, and hence if emphasis is given to much shorter time scales, the trends will drown in noisy variations.

But on shorter time scales, that's not always the case.

Researchers who have traditionally focused on seasonal or shorter time scales talk about things like vertical shear, ITCZ latitude and African wave characteristics as centrally important.

The dynamics of solar processes can be captured on shorter time scales, and the improved light - gathering capacity of the new telescopes allows us to extract more information from spectral lines with higher fidelity and accuracy, especially with respect to magnetic field measurements.

On shorter time scales, however, changes in heat storage (i.e., ocean heat uptake or release) can affect global mean temperature.

On shorter time scales, and layered on top of Pacific Decadal Oscillation variation, the Pacific North American pattern and the El Niño - Southern Oscillation cycles (see Climate chapter) can also affect variation in snowpack.

Certainly, there is no reason to believe that CO2 as a climate driver has been undermined in any way, especially on shorter time scales.

On this latter scale teleconnections manifest as a response of middle - latitude weather to the dominant modes of variability of the tropics (the Madden - Julian Oscillation and the Boreal Summer Intra-seasonal Oscillations, which similar to El Niño and La Niña characterize variations of climate but on shorter time scales).

While the atmosphere is mainly causing climate variations on shorter time scales, from months to years, the longer - term fluctuations, such as those on decadal time scales, are primarily determined by the ocean.

Sintering can take place at lower temperatures, over shorter time scales than for larger particles.

This world of the moment, which is all we know, becomes the setting for an illusory extension into longer or shorter time scales which then seem to occupy a portion of an external time in a relation of the phenomenal to the absolute.

It's not measured on years anymore; you can actually see it in a shorter time scale.

(General Fusion) just went for a shorter time scale.»

But earning and saving knocks spots of interest compounding over short time scales and is the only way to build up a relatively large fund for late starters, or late higher earners (same thing maybe).

My recollection is by this point in the book he'd had to substitute a proxy scaled market, and argue for the applicability of the measures over short time scales, so this suggests to me a major re-jig of my portfolio would be premature.

However, evolutionary theory does not consider such short time scales, but rather developmental changes occurring over millions of years.

Regarding observations of speciation within the fossil record, we now know we shouldn't expect to see Darwin's proposed gradualism given the relatively short time scales and the probability of capture within the fossil record (i.e. new species populations will be small and less likely to be reflected).

What we're now seeing in certain sectors is that entire classes of jobs become obsolete on short time scales (say a decade), making the retraining needed more like going back to school for several years.
