I saw that thread too, and was horrified—horrified that people were downvoting Stuart. And actually, on reflection, that that comment was upvoted is pretty horrifying too. The comment claims ambiguity in Stuart’s post when there is none
Strong disagreement. Stuart_Armstrong uses interchangeably the phrases “global warming denial,” “someone who denies the existence of anthropogenic global warming (AGW),” and “global warming skeptic.” There is significant ambiguity there- many people identify as “global warming skeptics” in that they are skeptical of the moral and political claims of the global warming movement, not that they deny the existence of AGW. Similarly, many people identify as “global warming deniers” because they deny the moral, predictive, or prescriptive claims put forward by the global warming movement.
(Note that Thomas, who did express doubt in AGW, got downvoted to −3.)
when Stuart was very specific that he was talking about denial of the very existence of AGW, rather than about disagreements on appropriate policy responses.
I didn’t see any effort on Stuart_Armstrong’s part to disambiguate those or notice that he needed to. For example, in your post, it looked like you carefully limited the consensus to the actual scientific consensus on historical anthropogenic climate change, and if Stuart_Armstrong had mentioned that he was just talking about the historical record, there wouldn’t have been a need for steven0461′s comment.

I’m not skeptical of CO2 as a greenhouse gas, or of the increase of atmospheric CO2, or that increasing CO2 levels will generally lead to higher temperatures, or that we have had higher temperatures in the last few decades.
But I am skeptical of the model projections into the future, and even more skeptical of the claims that the accuracy of those models have been established when they’ve proven inaccurate for the last decade. When you make predictions that fail, you should be decreasing your certainty in the model that gave those predictions.

That demands seems a little strange. Should he have disclaimed any claim about future warming? But given past warming caused by human CO2 (and other) emissions, we should expect more warming if we continue that activity (actually, the IPCC thinks warming would continue even if CO2 were kept at current levels).
On the other hand, I’m not seeing any way to read Stuart’s statement as anything like, “if your estimate of future warming is only 50% of the estimate I prefer you’re irrational.”

I put “predictive or prescriptive claims” into my second bit, but I probably should have included it there as well.
