, your arguments make sense. Unfortunately they come raethr late.Here is the way I see it, basically. You can trust science or not. There are multiple reasons to believe that there are huge risks associated with our current trajectory. These risks are confirmed by, essentially, all the worlds leading scientific bodies.If you choose not to believe this consensus, then you can take on the expense of replicating the work or even improving upon it. Given the time frames involved this would have been much better to undertake a decade ago or more. The underlying information has not drastically changed since then.The ideal would be a completely independent verification.You would need to put scientifically adept people on the case who were essentially independent from the current climatological community and with whom you had some sort of established network of trust. Then you would need to expend comparable or greater resources on their efforts than go into existing work. (The dominant cost of the typically quoted amount, 2 billion, goes to obervation satellites. You'd have to decide whether to replicate those. You would be looking at relatively modest expenditure on the order of a billion dollars. If you don't trust the instruments, much more, up to the cost of replicating much of NASA's unmanned research programs. The latter seems excessive; in any case it would enforce a delay in excess of a decade.Then you have to decide whether to do this as a clean room implementation. Here there are problems either way. If you don't expose the participants to the existing literature, there is no guarantee that they would catch up to the current state of knowledge, which emerged over seventy years. In any case few would agree to such conditions for a long time.Since you can't close the literature, your participants' objectivity would be tainted by existing expectations. This latter case is perhaps the best you can do, in practice.Consider this, though: the purpose of IPCC was to provide a sober review of the literature for the policy sector, and the result is that IPCC is perceived as every bit as tainted as the community it reviews. In the end, you would just get more climatologists. No matter where they started, once they were sufficiently educated their jaws would drop to the floor, one by one, and they'd cuss and basically see how idiotically we are behaving. Perhaps more realistically, you can demand more formal record keeping and more effort at communication with the larger scientific community and the public. These tasks are difficult and hitherto unfunded. While I very much wish more could be expended on these things, again you are looking at a significant spin-up time.Anything one could do to enhance credibility and checking will have time and expense associated. Since the arguments that serious implementation efforts must start by 2010 to avoid huge costs have been known for about 15 years it seems raethr late. Accordingly, it is irrational not to begin putting the policies in place now. Maybe whatever improvements you might wish to fund might be happening in parallel. These expenditures will remain tiny compared to the energy sector and should. If you want better qulaity of results, stop cutting funding and squeezing the work as punishment for getting the wrong results.The model I use every day suffers badly from a cut that essentially fired the documentation and support team just as the code was finalized. I waste weeks guessing how to run this or that version. These are weeks I don't have to set up better software or build better tests.
