I was wanting to discuss a couple substantive issues with the latest IPCC report and how the review process either failed, or actually introduced new problems, but unfortunately the IPCC has not published the draft versions and reviewer comments they said they'd publish. They explain this:
— IPCC (@IPCC_CH) October 10, 2018
Which is rather strange given the IPCC has launched a PR campaign in which it talks about how the latest report has now been published. The contradiction here doesn't seem to bother the IPCC. I've talked about it before, and I've actually contacted the IPCC directly about this issue in the past. Their response has always been to shrug it off, because apparently it is okay for the IPCC to blatantly contradict itself. Because... consensus?
I don't know what to make of the IPCC simultaenously saying this report is both published and not published. I don't know what to make of the IPCC saying draft versions can't be quoted, cited or distributed while running a PR campaign in order to get as many people to read a draft report as they can. It's weird. And perhaps more importantly, it interferes with anyone's ability to fairly judge the reports the IPCC makes. I don't know how the IPCC can "publish" its report then say it won't release its drafts and reviewer comments for months because the report isn't published. What I do know is there's a lot of material we can't effectively discuss because of it.
That all said, Skeptics don't care about this. You won't see them complaining about this. They won't complain because they don't care. Skeptics are lazy and don't actually want to examine things. They just want easy talking points they can throw around. This report is providing some perfect examples. Today, I'd like to highlight one from the big name Ross McKitrick:
New IPCC SR15 report relies on Marcott 2013 to contrast recent warming with past 7,000 years. Marcott et al. said their study should not be used for that purpose, after critics hammered their poor 20C data quality.

This is idiotic. The highlgihted passage by the IPCC cites two trends, one from recent times and one from times long ago. As references, it cites two sources, one a temperature record of modern times and the other a temperature reconstruction of olden times. McKitrick says this is wrong because the second source, the one reconstructing temperatures thousands of years back in time, can't be used to show modern temperatures. In doing so, he simply ignores one source is a reconstruction of modern temperatures.
There are many problems with the new IPCC report, and oen could even argue this particular passage is wrong. But as long as Skeptics keep making and embracing these sort of lazy, idiotic talking points, why should anyone listen? Why should anyone care? They shouldn't. They won't.
Still, tomorrow I'll talk about a troubling issue in this IPCC report. I can't give as much context as I'd like since the IPCC knowingly makes false claims to the public, but I'll do what I can.
