No, that is not correct, both papers seek to determine whether the observational data are consistent with the models, however Douglass et al use a statistical test that actually answers a different question, namely «is there a statistically significant difference between the mean trend of the ensemble and the observed trend».

p.s. To compare to Vahrenholt's forecast, here's a comparison of earlier model projections of global temperature for the IPCC (prediction with the CMIP3 model ensemble used in the 4th IPCC assessment report, published in 2007) with the actual changes in temperature (the four colored curves).

The model weather is the part of the solution (usually high frequency and small scale) that is uncorrelated with another simulation in the same ensemble.

One can temper that with studies of paleoclimate sensitivity, but the ensemble results still should be borne in mind, since doubling CO2 takes us into a climate that has no real precendent in the part of the climate record which has been used for exploring model sensitivity, and in many regards may not have any real precedent in the entire history of the planet (in terms of initial condition and rapidity of GHG increase).

A comparison of observed sea ice decline with the model ensemble spread can tell us only how likely an observed trend is relative to that ensemble.

Although a useful process to see which models should have more weight, and which ones should be discarded all together, the average that the ensemble produces will automatically have a higher correlation with observation data simply because of how far a set of numbers are spread out from each other.

We then perturb this input with the change in the seasonal mean SSTs and the seasonal mean state of the atmosphere as projected by an ensemble mean of global models for the end of the 21st century.

[Response: I wasn't trying to suggest that tacit knowledge was some kind of opinion that all scientists must agree with, but rather it is the shared background that, say, everyone using climate models has — i.e. why we use initial condition ensembles, how we decide that a change in the code is significant, what data comparisons are appropriate etc..

Global climate model projections (in CMIP3 at least) appear to underestimate sea ice extent losses with respect to observations, though this is not universally true for all models and some of them actually have ensemble spreads that are compatible with PIOMAS ice volume estimates and satellite observations of sea ice extent.

What deniers want to do is skip all that, misrepresent the models by claiming they predict steady warming (conflate multi-model ensemble means with individual model runs), and conclude the physics is wrong and CO2 causes less warming.

[Response: There are a couple of issues here — first, the number of ensemble members for each model is not the same and since each additional ensemble member is not independent (they have basically the same climatological mean), you have to be very careful with estimating true degrees of freedom.

He claims that this can be corrected for, but he still isn't using the proper null — in M&N they show the results from the ensemble means (of the GISS model and the full AR4 model set), but seem to be completely ignorant of the fact that ensemble mean results remove the spatial variations associated with internal variability which should be the exact thing you would use!

I did so, and in so doing pointed out a number of problems in the M&N paper (comparing the ensemble mean of the GCM simulations with a single realisation from the real world, and ignoring the fact that the single GCM realisations showed very similar levels of «contamination», misunderstandings of the relationships between model versions, continued use of a flawed experimental design etc.).

My understanding is that GCMs are run several times with known forcings (as far as we can determine them) but random natural variability (e.g. ENSO), so the end result is an «ensemble» of model runs characterised by mean, standard deviation etc. rather than following precisely the year - to - year variations of global temperature.

With «mean climate», surely the model ensemble mean is meant, however the «real data» to base the tuning on by definition is restricted to the single realisation of Earth's climate (including cloud cover caused by, for instance, multi-decadal oscillations instead of AGW feedback).

1) Attempts to constrain ECS with shortwave cloud feedback alone (e.g. Sherwood et al. 2014) miss the possibility that real - world longwave feedbacks could lie outside that spanned by the model ensemble (the infamous unknown unknowns).
