To add to my previous comment: I do agree that some skeptics express very high confidence in low climate sensitivity values, more than is arguably warranted from the evidence (even if it is consistent with the evidence). Overconfidence in such estimates is a sign against being taken seriously. At the same time, conducting an exercise that comes up with a specific estimate, possibly just as an illustration of the sort of thing that seems to be true, doesn’t seem problematic to me.
