Restoring Integrity in Climate Science

What Climate Sceptics Actually Say

The growth of WUWT, and skeptics blogs generally over the last few years, is a miracle.

But we need to consolidate our understanding of climate science.

It's a nuisance to have to constantly remind the warmists of references one keeps losing sight of, or slightly doubts the validity of. We need the best quality. We need it all together in one place. We need it easily referenced and understandable by non-specialists. We need to have one place we can refer all warmists, when they claim that it's proven that CO2 is rising because of us and is having a warming effect. And we need to know that we are all behind it, because we all have the opportunity of contributing to it.

Exactly what Wikipedia should provide. But because of the prevalent AGW cult, and William Connolley at Wikipedia, it does not. And whilst the good news is that Connolley has been topic-banned, I don't think this is enough for us. I think we still need our own wiki. I have believed in this for a while. And when contributor Shen at Climate Audit set up a MediaWiki platform precisely for this, I was delighted, and started to build up a proper wiki. Shen was somewhat distant, but largely supportive. I must have started some 30-40 pages, some of which had reached quite a reasonable standard, when it suddenly disappeared into the great blue yonder. This was a catastrophe, especially since, unlike my normal practice, I had not saved pages elsewhere. I had prepared everything with a view to publicising it on WUWT and opening it up for lots of contributors, by building up a skeleton structure as best I could. Richard Ritter helped me too, and it looked as if we were really going to be able to open things up and reach a high standard, when poof! it disappeared. Richard planned to start a new platform, but by now my time was completely taken up elsewhere and it was impossible, once again, to build.

However, my experience taught me a lot.

Firstly, we need a sceptics-only wiki. We need a setup where only proven sceptics can edit or set up the front pages - even while all can contribute to comments. Warmists have Wikipedia and they simply cannot complain - we have a lot of work to do, to right the balance.

Secondly, it would be good to have a MediaWiki platform again - but I do not have the technical expertise to set up such a platform - so the first crowdsource request is for someone who can do this.

Thirdly, it would be good to

At WUWT and similar blogs we have a fantastic tool to hand, if we can command it with integrity. Crowd sourcing.

The vision is for a small wiki or blog, built simply to answer the 119 "scientific answers" to the "skeptic arguments" at John Cook's Skeptical Science pages. So in addition to his two columns, a third column is needed: "What Climate Skeptics Actually Say". John Cook has done an excellent job, in his way, and runs the most courteous and accessible of all the warmist blogs going. I used to frequent his blog when I was a warmist myself. But as we know generally, all the official "answers to skeptics" are straw men, or answers that leave out vital parts of the evidence, or answers to issues that belong to the skeptic fringe and do not really matter regarding the catastrophic anthropogenic climate change delusion, and restoring proper science.

I think it is worth while just concentrating on answers to Skeptical Science, for these reasons:
(1) Skeptical Science is a clean, well-formatted blog with an index page; each topic page (at the Intermediate level) has a good list of references; skeptics as well as warmists can post there; it is generally courteous and easy to follow. It is a good model.
(2) A blog or wiki set up in direct response could be referenced by the Our Climate app, which would be especially appropriate since, as we know, John Cook has turned his pages into an app there too.
(3) A website with answers to 119 issues is neither too big to manage, nor so small it cannot do justice to key issues. And by using a similar format, answering point-for-point, this will in itself draw a degree of interest and status.
(4) The Royal Society "Climate Change Controversies" is in short pdf format, with only 8 points that are all straw men.
(5) The BBC "Climate Skepticism" likewise only answers the "top ten" briefly and with nowhere to respond.
(6) New Scientist's "Climate change: A guide for the perplexed" is a bit better. It sets out some 30 skeptics' issues and provides answers and space to comment (if one is a paid-up subscriber). But it is still not as detailed as Gristmill, RealClimate, or Skeptical Science. But it is still small compared with Skeptical Science. And less accessible.
(7) Gristmill's "How to Talk to a Climate Skeptic" is a tour-de-force by one interested individual. But it is revoltingly snide in its tone, dividing its categories of arguments into Stages of Denial, Scientific Topics, Types of Argument (Uninformed, Misinformed, Cherrypicking, Urban Myth, FUD, Non-Scientific, Underdog theories and Crackpottery), and Levels of Sophistication (Silly, Naive, Specious, and Scientific). It has few references and little space for meaningful skeptic contributions to the threads.
(8) RealClimate has perhaps the biggest collection of some 400 scientific articles, covering nearly 20 "Themes" including "Responses to common contrarian arguments" which includes some 50 articles. RC is frequently quoted as the prime authority, and indeed, it's readable, accessible. But we all know how useless it is to even begin to post there, to challenge them.

Now if this project is to work, and be used and recognized, it needs to refine the best of our collective wisdom as skeptics. It needs a platform, and it needs a strong hand in charge, capable of giving editorial rights to appropriate people. I strongly believe we do not want warmists as contributors for this project; I think we know the warmist arguments and tactics well enough by now, and there are other places where warmists can post, as well as Wikipedia and RC where warmists rule completely. This way people can build up answers good enough to be backed by the whole climate skeptics' community, without being worn out by constant distractions. I hope that many capable and knowledgeable skeptics would contribute, effectively constructing a document, a statement, which the whole community that is skeptical of CAGW can own. And I would hope that pages can be featured regularly by blogs like WUWT, to keep drawing interest and contributors.

I am not in a position to oversee this project, to moderate, confer appropriate editorial status, or to provide a website platform. I hope that there are readers here who would be willing to step forward, to do this "barn-raising" to good standards. For starters, readers might like to write draft articles - choose one or more of the numbered issues below - first come, first serve, but all skeptics "of good standing" will be able to edit and rewrite later. Prove you are of good standing by drafting a good piece, and you will be given editorial rights for all articles, when the pages are set up.
