A study with high internal validity boosts our confidence that effects we observe are attributable to the program itself and not to other extraneous factors — that is, we are confident that the program caused the outcome we observed.
So after patiently observing for «at least 30 years» in what is it that you then expect to be able to express an opinion with «very high confidence»?
We have fairly high confidence that we observe the history of Heinrich events (huge discharges of ice - rafted debris from the Laurentide ice sheet through Hudson Bay that are roughly coincident with large southern warming, southward shift of the intertropical convergence zone, extensive sea ice in the north Atlantic, reduced monsoonal rainfall in at least some parts of Asia, and other changes), and also cold phases of the Dansgaard / Oeschger oscillations that lack Heinrich layers and are characterized by muted versions of the other climate anomalies I just mentioned.
Hoerling: «We can also say with high confidence that no appreciable trend toward either wetter or drier conditions has been observed for statewide average precipitation since 1895» — «At present, the scientific evidence does not support an argument that the drought there is appreciably linked to human - induced climate change... In short, the drought gripping California has been observed before.
«In the case of the Arctic we have high confidence in observations since 1979, from models (see Section 9.4.3 and from simulations comparing with and without anthropogenic forcing), and from physical understanding of the dominant processes; taking these three factors together it is very likely that anthropogenic forcing has contributed to the observed decreases in Arctic sea ice since 1979.»
Tropical cyclone activity and intensity increasing Record droughts, floods, heat waves, cold spells, high tides occurring Unequivocal warming of the climate system observed with very high confidence that human activities are to blame Temperature rising even more dramatically in Arctic, threatening ice loss and extinction of species Halving human CO2 emissions immediately might save the planet from catastrophe.
The point to be made regarding that paper is similar to the one I made above: there is evidence that internal variability (to the extent it can be equated with the AMO) has affected the rate at which anthropogenic forcing has warmed the surface, but most of the warming must have been forced, with the observed positive ocean heat uptake data excluding more than a very minor role for internal variability in the warming itself with very high confidence.
This hardly seems to fit the IPCC description that «[m] odels reproduce observed continental - scale surface temperature patterns and trends over many decades» or is grounds for having «very high confidence» that the «model simulations show a trend in global - mean surface temperature from 1951 to 2012 that agrees with the observed trend.»
But what the IPCC wrote [TS.5.3] was «With high confidence the transient climate response (TCR) is positive, likely in the range 1 °C to 2.5 ºC and extremely unlikely greater than 3 °C, based on observed climate change and climate models.»
Models are able to reproduce many features of the observed global and Northern Hemispher (NH) mean temperature variance on interannual to centennial time scales (high confidence), and most models are now able to reproduce the observed peak in variability associated with the El Niño (2 - to 7 - year period) in the Tropical Pacific.
Such solecisms throughout the IPCC's assessment reports (including the insertion, after the scientists had completed their final draft, of a table in which four decimal points had been right - shifted so as to multiply tenfold the observed contribution of ice - sheets and glaciers to sea - level rise), combined with a heavy reliance upon computer models unskilled even in short - term projection, with initial values of key variables unmeasurable and unknown, with advancement of multiple, untestable, non-Popper-falsifiable theories, with a quantitative assignment of unduly high statistical confidence levels to non-quantitative statements that are ineluctably subject to very large uncertainties, and, above all, with the now - prolonged failure of TS to rise as predicted (Figures 1, 2), raise questions about the reliability and hence policy - relevance of the IPCC's central projections.
``... observed global warming is now attributed with high confidence to increasing greenhouse gases (IPCC 2007a).»
He said that ``... the global warming is now large enough that we can describe with a high degree of confidence a cause and effect relationship between the greenhouse effect and the observed warming.»
