I’m going to respond to more than just the above, but I quote it as a reference to what I’m responding to, so let’s start with Curry.
Judith Curry is someone that I’m quite familiar with. Yes, Judith Curry is a “real” scientist – or at least, she used to be – but is now doing her field a considerable disservice in her ranting blogs. If you actually look critically at her publications, she hasn’t published anything since 2011, and lists only one paper there that was actually published (look at the details). Curry is the worst kind of hypocrite – someone who accuses an entire scientific field of lacking balance and objectivity, and then spews forth intentionally deceptive, self-serving bullshit on her personal blog, ostensibly in the name of objective balance. Ray Ladbury, a physicist at the NASA Goddard Space Flight Center with a background in science education and science journalism, had a great comment about Curry that perfectly sums up my own feelings:
There are actually better examples of denialists who publish – possibly the best of them is Richard Lindzen – but as I said earlier, when they do so it is a kind of Jekyll and Hyde persona – their published papers are generally legitimate and not even particularly controversial – Lindzen mostly does atmospheric physics – but then they use their acquired reputations to rant in public op-eds and blogs about issues that are unsupported by any research of theirs or anyone else’s.
But Curry is a disgrace to her profession; whether she has turned to blogging for fame or profit or the onset of dementia I can’t tell, but her antics have been well discredited here and here and here, just for starters. Curry’s antics have even caught the attention of Sourcewatch, and Scientific American published an article about her that I thought was much too kind, but nevertheless lays out many of the problems with her positions. Kind of reminds me of the old saying that, for a publicity whore at least, there’s no such thing as bad publicity.
The reasons for all the attention are not hard to understand. She is the darling of WUWT and Watts’ gang of denialists; she’s teamed up with blatant denialists like McIntyre, Pat Michaels, and many others; she’s been courted and quoted by aides to the lunatic senator Inhofe; she’s been quoted and interviewed on denialist sites like Friends of Science and SPPI, the latter I believe slaveringly quoting from an interview with her published in a fine scientific journal called “Oilprice.com”, in which she asserts, among other things, that the IPCC is useless and that any possible attribution of climate change to CO2 is unknown, assertions with which the fine scientific journal Oilprice.com enthusiastically agreed.
You also mention John Christy, and he’s not much better. He’s an associate of the complete crackpot Roy Spencer, and the two of them frequently work together…
As for your link to “denialist climate scientists who publish”, I count 7 actually listed as climate scientists, about a dozen more in somewhat allied fields. The IPCC had almost 1000 of the world’s foremost climate scientists contributing to the AR5 alone, out of tens of thousands of qualified climate scientists in the world. What percentage are the avowed denialists? A fraction of a percent, it would appear. Actually, considering the money to be made from the massive disinformation campaign that has been underway for more than 15 years, I’m really surprised the number is that low. We can perhaps take heart that there is more integrity in science than in most fields.
