Climate models are currently, at best, when treated as an ensemble (if you buy that as legitimate)
Is there a methodological reason to NOT treat the ensemble as legitimate? Please describe this reasoning in detail.
skirting along the p 0.05 level of significance in the validation period.
Define precisely what you mean by "skirting along". How far below 0.05 are the models results, exactly?
Pointing this out is considered trolling -- it probably offends some religious sensibilities.
I suspect you are misinterpreting the responses. Mostly when we dig down on these sorts of remarks, high level, without data or empirical basis, no repeatable observations, we find them to be the work of some deceptive, brainless, mouth breathing denialist. You might be an ok chap, but I can't really make a conclusion until I've seen the data.
It's a matter of probability. Perhaps someone who sounds like a denialist is, in spite of the evidence, a rational, coherent person who is nevertheless ignorant of the science or misled by paid shills (like Anthony Watts who is paid a salary by the Heartland Institute to LIE about climate science, or Judith Curry, who deliberately misleads by wrapping genuine science in a penumbra of sneering psuedo-scepticism).
Generally the best measure is as follows:
1. The person refuses to provide specifics but only speaks in generalities - likely a committed denialist
2. The person provides specific (albeit incorrect) facts. ignorant or misled by liars
Like many people I have a lot of sympathy for the genuinely misled and will try to help them if I can. The deliberate lies and deception on the part of the denier hierarchy makes my blood boil.
Tightening the threshold as the article suggests would mean the model results are not "significant" (i.e., not reasonably distinguishable from natural variation -
Actually the article makes no mention of anything related to climate science. It is mainly focussed on instances where results are found not to be reproducible and using a frequentist methodology. Climate models are very reproducible and don't use a frequentist method - they make predictions, not observation.
n -- note that I am not a "denier" and that I do accept that CO2 is a greenhouse gas etc. etc.; I am however hugely skeptical of most climate and environmental science that I have investigated).
And yet you refer to these supposed problems in the climate science in generalities. Why is that?
