Andrew Revkin is normally a great reporter, so it is particularly disappointing when he turns in a shocker. He’s fallen again for the attraction of a middle ground (see Middle Muddle for the previous occasion). If the IPCC says 2+2=4 and the CEI says 2+2=6, well Revkin reckons that Lomborg saying 2+2=5 sounds nice and sensible. But just because Lomborg is in the centre between the scientists and the think-tankers, doesn’t mean that he is right. To see if Lomborg is right, you need to look at the scientific evidence, and Lomborg always cherry picks and misrepresents the science. For example, look at what Lomborg says about polar bears.
