Judith Curry has waded into the consensus discussion by highlighting a post written by two people I’ve never heard of and – from what I can find – have no actual expertise in this topic whatsoever. Apparently the key point is that
….. the fact that so many scientists agree so closely about the earth’s warming is, itself, evidence of a lack of evidence for global warming.
Huh? Yup, you read that right. Apparently the idea is that as the level of agreement increases, our willingness to consider – or fund – alternative ideas decreases, and we actually start encouraging others to avoid considering these alternatives. Therefore we restrict our ability to increase our knowledge. Drawing this conclusion doesn’t require any actual evidence that we are discouraging the investigation of alternatives. Also, that we might have already elminated most alternatives does not seem to be an option.
I keep writing, and then deleting, a discussion about this. This is because it is such nonsense, actually discussing it further seems to be giving it way too much credence. If you’ve wondered why I haven’t mentioned Judith Curry’s blog recently, this is a good illustration of why. If Judith is going to promote this crap, there’s not really much point in even reading her blog, let alone wasting any time writing about what she promotes. I think I shall endeavour to continue in that vein.
