Not exact matches

I think it's worth understanding that the author is assessing climate variability from an entirely regional perspective, a scale at which the global warming signal is much harder to detect.

Even if it were real physical variability, at that short time scale I would not expect it to be linked to global temperature in the way that I expect this link on longer time scales.

The study demonstrates the importance of understanding how climate variability on a regional scale may at least temporarily obscure larger forces acting on the global climate system.

``... My comments quoted above refer very specifically to the potential for global models to give more precise probability distributions of outcomes at the regional and decadal scales which are dominated by intrinsic interannual and interdecadal variability.»

However, my comments quoted above refer very specifically to the potential for global models to give more precise probability distributions of outcomes at the regional and decadal scales which are dominated by intrinsic interannual and interdecadal variability.

Individual decadal - resolution palaeoclimatic data sets support the existence of regional quasi-periodic climate variability, but it is unlikely that these regional signals were coherent at the global scale.

However, models would need to underestimate variability by factors of over two in their standard deviation to nullify detection of greenhouse gases in near - surface temperature data (Tett et al., 2002), which appears unlikely given the quality of agreement between models and observations at global and continental scales (Figures 9.7 and 9.8) and agreement with inferences on temperature variability from NH temperature reconstructions of the last millennium.

Global and regional climate models have not demonstrated skill at predicting regional and local climate change and variability on multi-decadal time scales.

The Regional Climate Impacts theme stresses the need to explain and interpret the potential impacts of global climate variability and change at the regional and community scale.

This paper reviews advances made during the last decade to better understand the impact of global SST variability on West African rainfall at interannual to decadal time scales.

(A) coordinate programs at the National Oceanic and Atmospheric Administration to ensure the timely production and distribution of data and information on global, national, regional, and local climate variability and change over all time scales relevant for planning and response, including intraseasonal, interannual, decadal, and multidecadal time periods;

The 25 D - O events during the last glacial, where temperatures rose and fell by 5 to 10 degrees C (10 - 15 degrees C for Greenland) within a span of decades that were «explained by internal variability of the climate system alone ``, deemed global in scale, and they occurred without any changes in CO2 concentrations, which stayed steady at about 180 ppm throughout the warming and cooling.

However, changes in climate at the global scale observed over the past 50 years are far larger than can be accounted for by natural variability.

Exactly, but using good numbers not a «hotchpotch assembly» for which it is claimed to be global temperature (there is no such thing, there is global energy content, but that is totally different story) So calculate correlation CET - GT from 1880 using 5 year bin averaging http://www.vukcevic.talktalk.net//CETGNH.htm P.S. your statement on natural variability on decadal scale is grossly misleading, you got about 130 years of good records so you need to look at multi-decadal picture.

In other words, trends and / or variability in larger - scale features of the climate (including rising temperature from global warming) are not very strongly (if at all) related to regional and temporal characteristics of streamflows across the U.S.

The results provide, for the first time, global observational evidence for the barotropic nature of large - scale ocean variability at mid and high latitudes.

Essentially, one needs to show that the behaviour of the climatic signal is distinct from that generated by natural climate variability in the past, when human effects were negligible, at least on the global scale.

My favorite quote from that paper is: «Because ENSO is the dominant mode of climate variability at interannual time scales, the lack of consistency in the model predictions of the response of ENSO to global warming currently limits our confidence in using these predictions to address adaptive societal concerns, such as regional impacts or extremes (Joseph and Nigam 2006; Power et al. 2006).»
