What’s seems indisputable is that, when it comes to the amount climate coverage overall, all signs point down. “I should note that I completely agree that, in general, there’s been a major decrease in climate policy coverage in the MSM,” Braun wrote in one of his e-mails. “In 2007, I certainly would not have guessed this!”

Indeed, few would have, and the fact that the decrease is evident even at E&E, where it can’t be chalked up to editors and reporters who don’t know or don’t care much about the story, is worrisome. There’s still a lot of really good climate change journalism out there, of course—and quantity does not equal quality—but it’s spread more thinly, and journalists are having tougher time finding solid pegs on which to hang it.
