Last week, the government released the Fourth National Climate Assessment. Not surprisingly, it’s largely consistent with the prior assessments. As other commenters have noticed, the primary difference from prior reports is one of emphasis; the Assessment now includes substantial information about the likely cost to the economy if we fail to address climate change.

I had been wondering whether it was worth doing a post about the assessment – and then I saw that the President, when asked about the cost analysis specifically, said simply “I don’t believe it.”

Well, if the President, who, the last time I checked, was the person constitutionally responsible for the output of the Executive Branch, says that he doesn’t believe it, it must not be so.

I guess there’s no need for a blog post.
