Update: see below for the latest bit of continuing obstinate idiocy from Steve McIntyre, plus another diagram, plus another reference.
There are undoubtedly a few knowledgeable people chuckling or groaning over an article Steve McIntyre wrote on his blog last week.

If you're wondering how anyone, even a climate science denier, could possibly make such a silly mistake, read on.
