	Sure. And a better understanding of how clouds formation 
works will tweak the models significantly, some issues are still in 
doubt, it but is unlikely to make any significant difference to the 
AWG theory itself. Right?
	Again - scientific debate continues on details, actual 
scientific consensus on big question unlikely to chance.

	Well, I think they agree its worth collecting as much more 
data and refining models they have etc.
	But that IS doing more work on the AWG theory.

	Yes. And you are misunderstanding. Every time you say 'they 
should spend more time investigating other theories' you are 
essentially saying 'they should add more flaky features'. Doing more 
basic research to support the theories they have, to make their 
models more complex, yes, good  idea.  No one is saying because there 
is a scientific consensus that you stop doing research on the topic.

	You seem to hate the computer modellers - but surely if there 
is an issue, the answer is to make them better?

	Which again, comes down to you simply saying that you will 
recognise a scientific consensus only a long time after it occurs. 
Well, if you want, but it doesn't seem rational in any way not to act 
on what we have now.

	It means further investigation will assume the same basic hypothesis.

	I'm at the point where 'predictions' is just a big flag 
saying 'Stefano has very odd ideas about the scientific method'. Yes, 
confidence leads to predictions. No one but you thinks this is in any 
way even slightly odd as far as I can tell.

first, my next sentence addresses that anyway

	Scientists PR is self-defence. In things like IPCC, or Manns 
stuff, you'll get confidence intervals of different predictions. If 
you insist on getting your ideas of what scientists say only from 
blogs or op-ed columns, you'll get a skewed idea of what scientists 
say, but that isn't their fault.

	No, I think there are no opposing theories that explain the 
facts as well.

	Fair enough, your view of science has lapsed into clear 
conspiracy theory here.
	You are saying not only does the climate science world 
rigidly suppress dissent, but they actually rigidly suppress being 
doing science if they think it might disagree with them?

	Sure, but that surely doesn't include 'collecting basic data'.
	And science isn't a single collective. If individual 
scientists see a paper worth of interesting stuff in a neglected 
area, they'll take a look.

	Well, when an economist tells you that your climate science 
is wrong because he doesn't like the economic implications, he has a 
pretty big burden of proof. When a statistician tells you your stats 
are wrong, thats a different story. You listen, and move on.
	(But really, Stefano, the time for sharpening knives for Mann 
has past. Let it go, let it go. He was one guy, it amounted to 
virtually no difference to the overall theory, condemning all climate 
science because Mann was naughty years ago just goes down the road to 
crankdom. People make mistakes - McKitrick himself has made FAR worse 
ones in published papers.)

	Academic background isn't the issue - its involvement with 
the field. Plenty of people outside the field of climate science have 
made contributions of value (McKitrick on occasion, Tim Lambert 
catching out McKitrick on other occasions...). But they've 
demonstrated reading the actual research, and written papers.
	I think having academic qualifications outside the field 
makes your opinion worth only marginally more than people in the 
field. If someone has a PhD in economics, or geology, then their 
opinion signing a document, or in an op-ed page, is worth only 
marginally more than anyone elses. If they've read papers and made 
specific criticisms based on their professional expertise, then thats 
a different story.
	I think actually reading and criticising the science on its 
details can present some challenges for those outside the field, but 
have some advantages too.

	You think arguments about statistics or computational fluid 
dynamics should take place on TV news or in newspaper op-ed columns?

>You really believe the public is not competent to receive this stuff?

	Well, I certainly think newspaper proprieters are going to 
think so when they consider putting arguments about statistically 
analysis in the newspaper.
	And at this stage, scientists who want to challenge 
scientific consensus have a fair burden of proof. A single 
interesting result from a scientist won't change the theory all on 
its own by now, so taking it to the new media is very premature.

>So the climatologists close ranks for fear of the public hearing that
>scientific discussion is still going on,

	No, the climatologists aren't afraid of discussion, they'd 
just like to have that discussion with other scientists. That way 
they can talk stats and model responsiveness and other stuff that 
interests them, instead of having to argue interminably about what 
the scientific method is and whether Mann was a naughty boy in the 
1990s. And maybe presenting their detailed findings to people 
interested in working out what to do about them, rather than just 
taking potshots.

>This is why I don't trust "the debate is over". It looks like 
>propaganda designed to deceive the public.

	No, its mostly something that interested members of the 
public like myself started saying because we were sick of actual 
propaganda designed to deceive the public actually showing up in 
major newspapers.
	The scientists mostly just said "IPCC is over there. Thats 
what we think."
	Cheers
