The possibility of observation - model mismatch due to internal variability must also be accounted for... so in fact, attribution studies sample the range of possible forcings / responses even more completely than a climate model does.

As long as we're talking about extreme weather events and attribution... although Kerry Emanuel is usually the go - to guy for the study of increasing tropical cyclone intensity, his 2005 and 2011 (linked to above by Stefan) papers being the most cited, there is a limitation of scope in that only the North Atlantic basin is covered by these papers, AFAIK.

It is of course true that a role for climate change has not been excluded in attribution studies — of course, the IPCC also did not exclude a role for solar influences, cosmic rays or for that matter, evil leprechauns.

--- I realize the attribution studies are apt to be ignored by those who feel they aren't needed to support their opinions; I post this not to «debate» but as a reference: attribution for those interested in the science.

«Since the AR4, there is some new limited direct evidence for an anthropogenic influence on extreme precipitation, including a formal detection and attribution study and indirect evidence that extreme precipitation would be expected to have increased given the evidence of anthropogenic influence on various aspects of the global hydrological cycle and high confidence that the intensity of extreme precipitation events will increase with warming, at a rate well exceeding that of the mean precipitation..

For example, after an extreme weather event, scientists often carry out single attribution studies to determine how the likelihood of such an event could have been influenced by climate change and short - term climate variability.

But let's make sure the research is not simply «agenda driven», i.e. to support a political agenda, such as the implementation of a direct or indirect «carbon tax», but real scientific studies to clear up the many uncertainties regarding the relative importance of natural and anthropogenic attribution of past climate change, for example.

However, taking account of sampling uncertainty (as most more recent detection and attribution studies do, including those shown in Figure 9.9) makes relatively little difference to estimates of attributable warming rates, particularly those due to greenhouse gases; the largest differences occur in estimates of upper bounds for small signals, such as the response to solar forcing (Allen and Stott, 2003; Stott et al., 2003a).

The extreme event attribution technique used for these studies was pioneered well over a decade ago.

And when you look at actual attribution studies in AR5, the fraction of warming due to AGW has a mean of 110 %, with less than a 5 % chance of anthropogenic causes being responsible for less than 50 % of observed warming.

Although temperature reconstructions are needed to study the Earth's energy balance, freshwater fluxes are arguably more immediately meaningful for ecosystem services and societal needs and will support detection and attribution exercises.

IPCC has stated (AR4 WG1 Ch.9) that the «global mean warming observed since 1970 can only be reproduced when models are forced with combinations of external forcings that include anthropogenic forcings... Therefore modeling studies suggest that late 20th - century warming is much more likely to be anthropogenic than natural in origin...» whereas for the statistically indistinguishable early 20thC warming period «detection and attribution as well as modeling studies indicate more uncertainty regarding the causes of early 20th - century warming.»

For instance, US politicians frequently assert that it is an open question whether humans are causing the undeniable warming that the Earth is experiencing, thus exposing ignorance of dozens of lines of independent robust evidence of human causation including attribution studies, finger print analyses, strong evidence that correlates fossil fuel use to rising atmospheric concentrations of greenhouse gases, and other physical and chemical evidence.
