Comment on AMS members surveyed on global warming by Jim D
David, it is very easy to test if two or more entirely different initial states lead to a statistically similar climate. This is one of the points of running ensembles. Another way to see this is that...

I believe that one of the justifications to reconsider a previous decision is false testimony at the first.

Jim, You are making a statement about the models which I do not doubt is true. It is true of a turbulent simulation with too much dissipation where you get the wrong answer. This is independent of...

Got it! Seeing it again, it is an even more awful question. The way I was taught to develop a question like that was to express the point in an initial statement, then get the respondent to comment on...

@NW, Re: "planes that come back" I prefer the word "historical" rather than "aprocryphal". I heard the story in 1978. Here is another telling from a <a...

GCMs resolve the main energy transferring modes of motion. Very little of it happens at sub-grid scales, except in the vertical direction, where adequate boundary layer and moist convection schemes are...

Don A @ 8/3 12.32. Doesn’t seem to work like that now, Don. You’re looking for a reasoned response, could there perhaps be another agenda?

I’m not sure what Chris means when he says that climate “can be understood in terms of forcings.” In a trivial sense this is always true. All systems can be understood in terms of forcings. The problem...

JimD, I don’t know how to answer you. All scales are important in fluid dynamics. Just capturing the main energy transfers tells you nothing about feedbacks like clouds for example. These depend on the...

Decadal scale predictability is not difficult because of the models, it is difficult because of the character of the turbulence that makes it even impossible for models that are perfect to machine...

The adoption of income redistribution policies is not necessarily a consequence of Keynesian macro-economics Cwon14, more likely socialism based on simplistic left wing ideology. The basic problem with...

David, I don’t get the feeling we are getting far in this discussion so I’ll highlight in a few points my main views here, and one that I suspect would be common to the bulk of the climate community. :...

Chris, I appreaciate your points. I suspect that Lorenz was speaking of the mathematics of linear systems, which it turns out is limited. My point is merely that many of these questions about fluid...

It’s something NPR and Dr. Curry have in common, delusional belief in their own objectivity. Go to the huffington post and you can find people who think NPR and the NYTimes are “right wing” and they...

Matt – I think all models are “tuned… to make better forecasts”. Not to do so would be negligent. My point was that the tuning was not done by consulting the climate trend that the model would...

After 20 years of trying, the climate scientists have not found any compelling evidence of anything unusual. How much longer do they need?

Not much of climate science is not “dodgy” (your word not mine). You missed the point. Steve, did you even watch the presentation?
