A number of readers have emailed me pointing to Richard Black's latest offering, which seems to carry a rather different tone to what has gone before. He is discussing scientific consensus and whether such a thing is of any importance.
A couple of years back, at one of the UNFCCC meetings in Bonn, I had a long chat with Viscount Monckton. As a scholar of Classics, he was able to detail with Classical derivation the reasons why consensus matters far less than simply being right.
And he is surely correct; after all, in more recent times, Galileo, Darwin, Einstein and Hawking are among those whose work broke with the consensus, yet turned out to be correct.
But if the presence of a consensus is irrelevant, so, logically, is its absence; which makes the continued use by sceptics' groups of the "consensus is cracking" meme a bit mystifying.
After all, how many times can you say it's cracking before people start asking "so why hasn't it cracked, then?"
In both cases - consensus and breaking consensus - it's surely the evidence that should count, not the number of people you can get to sign your letter.
