When a blogger makes mistakes she or he has several options. Ignore it and hope it goes away, muttering an acknowledgement in an obscure reply to a comment, refusing to believe she or he is wrong. I’ve probably done all of those in the past, although I’ve certainly been more likely to notice it in others.
In recent discussions of Matt Ridley’s essay on ten tests required prior to acceptance of current climate policy I made the rather bold statement that we have clear evidence that temperatures have been higher at various points in the Holocene.
Blogger and climate activist William Connelly (Update: William’s surname is Connolley–and as misspelling his name could easily be perceived as a provocation, I doubly regret this error.) challenged that statement and I found that I could not back it up.
I think it’s important that I acknowledge clear error where I can. (I’ve done it in the past, apologizing to Joe Romm, who I consider a very bad actor in the climate debates, when I accused him of writing that sea level rise was going to be absurdly high–he didn’t. He just quoted others who did.) So I hope to be starting a tradition here. I also hope I don’t have to take advantage of this new tradition frequently.
I’d like to open the comment thread for further discussion of Holocene temperatures for those who are interested.
Thanks William for pointing out my error.
