No, if I said it, it's still here in the archives. Maybe you've
confused me with someone else.

My information on GCMs came from reading their summaries (supplied by
each GCM group), reading as much of one global climate model's FORTRAN
spaghetti source-code as I could stand, and, mostly, _directly_ from
one of the world's preeminent experts, who works on them.

So, I've always known the difference.

I know the difference. But suppose I didn't--it still doesn't
matter. Cast aside your irrelevant bile and consider: we're in a 10-
year cooling trend. I don't remember any stern warnings from
climastrologists this was imminent, do you? Quite the opposite. But
your memory is better than mine--you remember things that didn't even
happen. Maybe you could cite those warnings for us.

Or is 10 years "just weather," and not climate?

I already stated I don't remember exactly. And part of it is that I
can't be too particular without revealing my source, which I am
entrusted not to do. That person is a scientist, not a politician,
and doesn't want to be sacrificed on the altar of AGW political
correctness.

The point being that the things fall apart in a few months, and
they're being used to forecast 50-500x that timespan and more. It
doesn't matter whether the 20-year forecast fell apart at t=two months
or three, or even four or five months, does it?

Obviously they're no good even at predicting in the 1-10 year
timeframe, or they would've predicted the current cooling.

Even sociology is subject to real world verification, and AGW fails
with amazing consistency. Experiment, per se, is not always necessary
(or even doable), but real world testing (does this model predict
historical data correctly and has it predicted recent experience and
many other verification tests). The AGW models also have failed this
with amazing regularity.

Yea, yea, i know, preaching to a mixture of the choir and unfaithful.

So, your argument is that you're a poor judge of source code when you
see it, and that it's all over your head anyhow. And, you can say
this without reading the code, or trying to see if it makes sense.
Therefore, the code is reliable.

You argue from faith: blind faith, sight unseen, in people you don't
know, their measurements, their adjustments, their understanding of
the processes, their integrity, and their code. All these are
necessary.

I've seen the code I critique; you say it's pure, though you've never
looked. That's faith.

I argue from knowledge, confirmed and supported by an expert with
impeccable recommendations from someone I know, trust, and respect.

I've linked to the code zillions of times before. Here's a starting
vector:
http://www-pcmdi.llnl.gov/ipcc/model_documentation/ipcc_model_documentation..php

From there you can get descriptions of each model, FROM its AUTHORS,
see the obvious limitations in summary form, and access source code
where it's available.

You'll notice that I pointed that shortcoming out years ago, here?
And you, with no knowledge, denied it.

You're leaping to a conclusion. I never said or intended that.

SOL James, but it doesn't, at least if you use the same model the AGW
group does. Even others that contain any of the canonical
presumptions of AGW fail to reconcile with well documented history.

Fortunately, there are a few disparaged models that do reconcile with
history.

I think i will buy another book of Menken quotes. Some did not age

Ain't going to happen. It will be a real problem for historians 300
years from now.
