I’m wiped out. Had a wonderful weekend as co-organizer of a somewhat scaled back Scientific Software Days, conferring with Steve about the imminent future of science communication, hanging around with him and other friends arguing the future of climate science, and even having the privilege of interacting with Bill Stein over dinner, which was a treat. Plus I’m seriously starting an exercise program which for a man of my sphericity is no small task, and trying to spin up some new projects, and, yeah, attend to the tedious details of the day job.
Today I was worthless; you can always tell those days because there are eighteen items on my Reader feed. That means I was in “I’ll just poke around a bit and see if I wake up enough to work” mode all day. Sigh.
Consequently not much time/energy for blogging this week. Read my feed if you’re bored!.
I’d like to draw your attention to this article by John Nielsen-Gammon. It makes me uncomfortable and I think it’s wrong, but it’s not obviously wrong.
My first response was “um, that can’t be right”.
My second response was “perhaps the question is ill-posed” but I think it isn’t. There’s a serious actuarial question here. To be sure, given that there is only one Earth rather than thousands, it’s not one that is easy to answer.
The question is essentially “How much more likely is an event on the scale of the recent Nashville flooding as a consequence of anthropogenic climate change?” John says not much, but his answer changes when you drop the “anthropogenic” term. In other words, he’s saying that changes in severe flood events to date have been real climate changes but not anthropogenic climate changes.
So I’m back to “um, that can’t be right.” I’m pretty sure there’s something more or less non-obviously wrong there, but what is it?
