«Our results and the historical record suggest that a high learning capacity and long distance migrations enabled Namibian elephants to shift their ranges to survive against high variability in climate and in hunting pressure,» said first author Yasuko Ishida, a research scientist in animal sciences at Illinois.

RE the main points made in the post, I think I have also used the same logic to suggest if natural variability is greater than thought, then our A-GHGs should also have a higher sensitivity.

Billet et al. suggested that such high variability is the result of diminished selection pressure in slower - moving mammals to maintain orthogonal semicircular canals.

OECD analysis finds that about 15 percent of variability in the performance of American students is explained by socio - economic factors; the OECD average is 10 percent.13 Research suggests that if the PISA results of U.S. students are adjusted such that the distribution of low - income students is more similar to other countries with comparable post-industrial economies, both math and reading results would look significantly higher.14 This does not mean the United States should not be concerned about international comparisons of educational achievement, but it suggests that the conclusions drawn from rankings based on national averages are limited and that reality is more nuanced.

Such close linkages between CO2 concentration and climate variability are consistent with modelling results suggesting with high confidence that glacial — interglacial variations of CO2 and other greenhouse gases [CH4, N2O] explain a considerable fraction of glacial — interglacial climate variability in regions not directly affected by the northern hemisphere continental ice sheets (Timmermann et al., 2009; Shakun et al., 2012).

AR5 section 9.5.3 concludes «Nevertheless, the lines of evidence above suggest with high confidence that models reproduce global and NH temperature variability on a wide range of time scales.»

-- I calculated potential intensity trends over the period 1980 - 2012 & The disparity between the reanalysis potential intensity trends over the past 30 years and the projected trends over this century suggests either that most of the observed increase in potential intensity (and actual intensity of high category storms) is due to natural variability,....»

RE the main points made in the post, I think I have also used the same logic to suggest if natural variability is greater than thought, then our A-GHGs should also have a higher sensitivity.

«Trend estimates from the SOS [Start of Spring] methods as well as measured and modeled plant phenologystrongly suggest either no or very geographically limited trends towards earlier spring arrival, although we caution that, for an event such as SOS with high interannual variability, a 25 - year SOS record is short for detecting robust trends.»

A new study suggests that species that have evolved in regions with relatively high natural climate variability may at the same time be more resilient... Continue reading →

Steve: Willis, I've posted late in 2007 about Kiehl's report that GCMs with high climate sensitivity adopted aerosol histories with relative low variability and conversely; thus there is more coherence in the GCM ensembles than in the underlying data — suggesting a certain shall - we - say opportunism in the aerosol history selection.

Extending the sea level record back over the entire century suggests that the high variability in the rates of sea level change observed over the past 20 years were not particularly unusual.

Shifts at decadal scales in the form of rivers — between low energy meandering and high energy braided forms — that suggested decadal variability of rainfall.

«An examination of the fossil record indicates that the key junctures in hominin evolution reported nowadays at 2.6, 1.8 and 1 Ma coincide with 400 kyr eccentricity maxima, which suggests that periods with enhanced speciation and extinction events coincided with periods of maximum climate variability on high moisture levels.»

This suggests that the uncertainties in measurements from these regions are larger than in other regions, and this will be exacerbated by the high variability.

If comments above are meant to suggest that the CET is irrelevant as a long term proxy for the changes in either the N. Hemisphere's or global temperatures variability, than it can be stated that the comments are wrong and misleading, since there is a high degree of correlation between the three relevant data sets.

Given that, «Climate simulations suggest that multi-decadal periods of high and low variability in the phenomenon known as the El Niño - Southern Oscillation in the tropical Pacific Ocean may be entirely unpredictable» DiNezio, 1014, we can not have confidence in any of our current ENSO forecasts

However, this high degree of internal variability (suggesting a positive and large feedback ratio, or «climate sensitivity» value) doesn't negate external forcing by any stretch, as Swanson and Tsonis pointed out in their conclusion:

Previous theoretical and model - based studies of the relationship between ocean bottom pressure (pb) and sea level (ζ) suggest primarily barotropic variability at mid to high latitudes for scales greater than a few hundred kilometers and periods less than a few months.

The lack of a forced SST - associated oscillatory signal in models suggests global temperature anomalies inferred from higher order observed RASST discriminants should signify internal variability.

On text noting high decadal variability in Arctic temperatures, Canada, supported by Norway, suggested removing a specific reference to a warm period observed from 1925 to 1945.

Here, high pressure studies show that force constants of iron bonds increase with pressure similarly for silicate and metals suggesting interplanetary isotopic variability is not due to core formation.

If the greenhouse effect played such a small role [edit], there should be an ENORMOUS climate sensitivity to «natural factors», which in turn strongly suggests there should be a much higher variability in global temperatures on a year - to - year basis.

Boyce et al have looked at stress reactivity in children and have shown that a high degree of variability exists.21 Traditionally, genetic predispositions were thought to play a major role in determining stress reactivity, but more recent data suggest that previous experiences also play an important role.22 Stress reactivity, much like brain development itself, results from a complex, dynamic interaction between genes (nature) and the environment (nurture) over time.

The concept of resilience and closely related research regarding protective factors provides one avenue for addressing mental well - being that is suggested to have an impact on adolescent substance use.8 — 17 Resilience has been variably defined as the process of, capacity for, or outcome of successful adaptation in the context of risk or adversity.9, 10, 12, 13, 18 Despite this variability, it is generally agreed that a range of individual and environmental protective factors are thought to: contribute to an individual's resilience; be critical for positive youth development and protect adolescents from engaging in risk behaviours, such as substance use.19 — 22 Individual or internal resilience factors refer to the personal skills and traits of young people (including self - esteem, empathy and self - awareness).23 Environmental or external resilience factors refer to the positive influences within a young person's social environment (including connectedness to family, school and community).23 Various studies have separately reported such factors to be negatively associated with adolescent use of different types of substances, 12, 16, 24 — 36 for example, higher self - esteem16, 29, 32, 35 is associated with lower likelihood of tobacco and alcohol use.

Additionally, individuals high in dispositional optimism also reported greater variability in state optimism, which suggested that the influence of individual differences might play a role in the ability to modulate optimism in response to situations (Shifren & Hooker, 1995b).
