Would you care to point out the most accurate predictive global climate model and its current track record? Would you care to point me in the direction of any peer-reviewed article that claims to be able to show what the radiant solar energy of the sun was 100, 300, 1,000 or 15,000 years ago? What were those levels relative to 2008? Would you care to show me the rigorous methodology used to be able to take accurate, credible temperature measurements across the globe beyond a couple of decades? Would you care to explain to me how a very localized warming trend can justifiably be extrapolated out to catastrophic levels 100 years from now? Would you care to explain how the last 10 years has been a net decrease in global mean temperature? Would you care to demonstrate how even assuming there is a significant global climate shift underway how the underlying causes are in any way materially different than innumerable global climate shifts from the past when man didn't even exist? Thanks in advance. http://www.nytimes.com/2006/05/02/health/02docs.html But lest that not dissuade you from the efficacy of peer-reviewing... http://epw.senate.gov/public/index.c...A-B35D0842FED8 If found a quote from that link that seemed quite applicable given your above response Quote:

And what is your point? That the overall consensus is not 100%? Has anyone claimed that? Quote:
Have you studied the pertinent literature in depth or are you relying on summaries? Are you familiar with the major articles and research studies generally regarded as foundational for the various sciences involved? Have you taken advanced courses in chemistry and physics? Geology? Meteorology? Environmental systems? Mathematics? Do you understand computational fluid dynamics? Have you studied partial differential equations? Linear algebra? Navier-Stokes equations? Have you studied numerical modeling of physical systems? Finite element method? Finite difference method? Analytic/boundary elements? Inverse modeling/parameter estimation? Grid resolution issues? Boundary condition selection? Can you summarize the various types of governing equations used to simulate physical systems and the strengths and weaknesses of each? Do you understand implicit vs. explicit solution schemes for transient models? Thanks in advance. And one more thing. Why don't we start with you telling us the margin of error of a petition in establishing evidence of anything? You are usually the biggest critic of polls. Now you are promoting a petition as evidence?

As far as "calling you out", the first time I had never seen anything you have ever written on this site that would indicate you knew anything about modeling. I said I could be mistaken. The second time you didn't respond to what I wrote, so I didn't know what you made of what I said.
Ooooohhhhh that was really calling you out, wasn't it? The petition wasn't evidence of anything other than to indicate that there are growing signs more people are coming about against consensus position. I've taken advanced classes in linear algebra, partial differential equations, stocastic modeling, experimental design, regression and time series analysis. Since I don't want to take too much of your time, why don't you explain how you develop a predictive model for global climate and fit it against anything than a very narrow sliver of time? Are we to believe that a sufficiently robust climate model exists where we can go back in time and indirectly measure all of the identified factors and their interaction with one another as a means of validating the model? This is the most fundamental question that needs to be answered. You can get as deep as you want into the highly technical world of fluid dynamics, CO2 studies, etc. etc. but unless you have a meaningful way to coalesce these individual components into a meaningful whole and have a means of validation, they have very limited value.

I don't understand all of this, not even close, but could you answer the applicability of these concepts to climactic change?

Navier-Stokes starts that system of analysis where one eliminates different factors to have even simpler equations. That's about all I remember, but then again I could be wrong.

perhaps the brainiacs are succeeding, and from little I've understood about the supercomputers working on these projects, they are making advances. As Lebowski has outlined, the amount of information to be digested, the level of expertise required and the breadth of the examination appears enormous. Perhaps he has experience and expertise in all those areas, but my guess, rank speculation, is it requires teams of persons coupling their knowledge together to come to meaningful conclusions. It looks downright impossible to make meaningful conclusions, but that's to an outsider. And if that is true, how is it possible to have a consensus as to correlations? I would like to know if Lebowski has the articles and journals which lead in this area, linked, so that I might not be so ignorant as I admit that I am.

My 2 cents
I'm not a climatologist, but I think I have a pretty good idea about how science works. We have a great competitive system in our country. The best, most rigorous scientists are devoted to the truth, and these scientists end up being successful. Bad scientists have short careers.
I have no reason to believe that climatology in America is less rigorous than other sciences. Since I'm not a climatologist, I choose to trust the experts. Critics need to come up with genuine, peer-reviewed data...or they need to just shut up and learn. If they aren't capable of testing hypotheses, then they have no room to talk.

But how am I as a lay person to know who is legitimate and who is not? Lebowski states that Lindzen should not be trusted because he accepts some money in the early 1990s. Am I to believe that only Gore's people are to be trusted? This is my dilemma as a lay person. Who is legitimate? How can I know? And how do I discern bias? I trust generally the scientific process, but I must be the only one who sees a potential for abuse or a skewing of findings in order to generate more research dollars.
