We should always begin our scientific pronouncements with this statement: "At our present level of ignorance, we think we know...," John Christy.
Read John Christy's viewpoint article on the BBC News Website:
No consensus on IPCC's level of ignorance
Read an alternative view from Martin Parry on the BBC News website:
oooo Mally ....
model validation is all part of the same process of making them "dance on the head of a pin".
Is that your expert opinion is it. What a ignoramus. You're really not that smart are you to make a telling comment as that. Seemed to have all muddled up calibration, parameterisation and validation in that poor old tired head. Off you toddle now - back to the nurses. Bye bye. Careful as you go.
and BTW wonder boy..
model validation is all part of the same process of making them "dance on the head of a pin".. but of course you knew that, and also know how difficult it would be coz you have done hundreds.
Yep !
... and I knew you would respond to that rather obvious bait as well..providing you knew of course.
So what is it Walker, just what experience have you had and what are your quals.I reckon at least a dozen people have asked you this over the last 3 to 4 years that you have been obsessing out on this blog.
Apart from being unemployed or on the public teat in a sinecure somewhere, just what have you done with our miserabble life that makes you think you are such an expert on everything.
Now dont forget its Monday and you need to start doubling your dose.
Gee dat sounds really complicated Malcolm. I never knew all that. Do you mean you could fit relationships and fudge the results. Wow !
You could contract to the boys and girls at CSIRO and BoM on model validation and attribution. Gee your insights could be invaluable. Maybe you're a friggin genius.
BTW gramps - MIPS is a bit retro - big in the day of course - they seem to talk teraflops now.
Ah, the cretinous and obsessed bloggerant responds in typical fashion.
As an alround know all, just how many main frame based programs/models have you designed and installed Walker.?
How much experience in IT and modelling have you had. What systems experience do you have Walker?
Whilst I may have used some poetic licence in saying any, meaning singular, it is not that hard to build programs/models of size, even if it required a team. My comment still stands.
You can make models dance on the head of pin--meaning, for simpletons like you Walker, that one can make them do exactly what one wants, it only requires effort and MIPS.
The principles are not hard.
Well Mally boy I'd like to see an individual with a half decent maths degree come up with a realistic global climate model.
Really I thought you knew a lot more. These sorts of little comments are invaluable in knowing that you're actually a clueless nitwit. You guys haven't the foggiest what you're talking about - becomes clearer every day. (Serious).
"Louis don't you think it is quite remarkable in some respects that one could produce a physically based model of global climate that not only reproduces many aspects of that climate but also a reasonable job of what climate is where."
No, not in the least.
Anyone with a half decent maths science degree and good computer knowledge, can make models dance on the head of pin. But if I can also make some dynamic graphics with a rotating globe and plenty of deep red colours to show how bad it is, I can really con the masses.
Also the fact that these people have been able to replicate past climatic conditions is no guarantee that their "forward projections" are anything other than pure guess work.
sorry - "based on physics".
Louis don't you think it is quite remarkable in some respects that one could produce a physically based model of global climate that not only reproduces many aspects of that climate but also a reasonable job of what climate is where.
Here we go again, another classic Luke non sequitur:
"GCMs have radiation models but on physics"
Huh????
