I was googling around a couple of weeks ago and happened to end up clicking a bunch of links that took me down a particular rabbit hole of climate change skepticism related to solar cycles. It was fascinating in a gruesome kind of way, but I never wrote a post about it and eventually it drifted from my mind. Today, though, Brad Plumer comes through with a link to a piece in the Independent explaining just where this theory originally came from and how it's become so widespread. Also, why it's wrong.1 Worth a read.
1An explanation largely notable because the scientist who originally advanced the sunspot theory refuses to address his main critic because he "is not a scientist." Good to see the tables turned here for once.
