Tree rings and many other chemical and biological climate proxy records, by their nature, tend not to record very large short - term fluctuations, and for this reason they are likely to
show less variability than actually exists in the climate record.»
I beleive it is likely that the Hockey Stick
shows less variability than there actually was, other reconstructions seem to show this, but the major findings were the most important (ie how the late 20th century fits in).

Findings
showed that when the thin subjects were stressed, their heart rates were significantly elevated and they had
less heart rate
variability compared to the normal or pre-obese subjects.
Indeed, since these cells expand exponentially with a constant relative cell elongation rate (Willis et al, 2016), the Timer mechanism could potentially drive much more
variability than the other mechanisms yielding
less robust outcomes, as we have
shown for roots.
While observational data from satellites
show less warming than predicted by most models, Santer and his co-authors demonstrate that the observed warming is consistent with models including both human and natural forcings, but inconsistent with models using only natural forcings and
variability.
We first demonstrate
less variability of global Pearson correlations with respect to the two chosen networks using a sliding - window approach during WM task compared to rest; then we
show that the macroscopic decrease in variations in correlations during a WM task is also well characterized by the combined effect of a reduced number of dominant CAPs, increased spatial consistency across CAPs, and increased fractional contributions of a few dominant CAPs.

show remarkable
variability in their response to medications.»

shows less biological
variability than measurement in plasma or serum.
It's worth noting that the variation in per weighted spending in OUSD is
less than the variation without weighting, suggesting that the incremental supports for needier schools are creating a somewhat more equitable environment, but there's still a surprising amount of
variability and certainly no obvious trend
showing needier schools getting more.
Anecdotally, it used to seem that some breeds were reliably
less allergenic than others, but more in depth research has
shown that
variability between individual dogs within a breed is extremely high.
He writes: «the data of landfalling hurricanes in the U.S. is
less than a tenth of a percent of the data for global hurricanes over their whole lifetimes», and
shows that from such a small subset of data and given the amount of natural
variability, there is no way you would be able to detect a trend by now.
Here is the detrended AMO index which has much longer cycles of 25 years or so but
shows much
less overall
variability than the ENSO has (+ / -0.6 C versus the ENSO at + / - 3.0 C).
During the Holocene optimum at a time when Wolcott
shows less than 0.2 C of
variability, Rosenthal
shows an upset in NH IWT that has the temperature rising 2C in about 500 years.
If the influence of solar
variability has been greatly underestimated, and the greater century - scale climate
variability shown in some reconstructions is a) correct and b) due to that solar
variability, then the climate sensitivity could be the same (or
less) then indicated by other reconstructions.
I agree that the models tend to
show less decadal ocean
variability than observed (given the obvious caveats on the observational side), but absolutely disagree that this implies that longer term estimates are off.
I think the 1975 change is attributable to two things: 1) Greenhouse gas forcings reached sufficient magnitude that they were clearly more dominant than the
variability shown in
lesser positive and negative forcings.
There's
less variability at both ends, but does your fit
show that this is a true property of the Earth system?
Figure 2 on p. 8 of the above survey
shows considerably
less variability for distributed farms, which it explains as follows: «The smoothing occurs because wind fluctuations are not perfectly correlated across the country, and the work reported by NGC to the Energy Review (ref.
However, our model
shows considerably
less variability than that observed, suggesting that other important sources of
variability exist which have not been included in the model.
«Our results
show that it is extremely likely that at least 74 % (+ / - 12 %, 1 sigma) of the observed warming since 1950 was caused by radiative forcings, and
less than 26 % (+ / - 12 %) by unforced internal
variability.»
Moreover, 370 years of tropical cyclone data from the
Lesser Antilles (the eastern Caribbean island chain that bisects the main development region for landfalling U.S. hurricanes)
show no long - term trend in either power or frequency but a 50 - to 70 - year wave pattern associated with the Atlantic Multidecadal Oscillation, a mode of natural climate
variability.
The stratospheric
variability is
less than observed, as
shown by analysis of the present 20 - layer 4 ° × 5 ° atmospheric model by J. Perlwitz (personal communication).
Modern continuous sampling (30 minute averages) in the same neighbourhood also
shows large
variability, but the monthly averages more or
less follow the MLO measurements with some bias:

less than 10 % of the
variability.
Children with ASD

variability in AR and used
less effective AR strategies compared to controls.
