At first glance, Richard Muller’s “conversion” from global-warming skeptic to true believer—based on research funded by global warming denialists—is a welcome surprise. Hey, people can change their minds! But on Stoat, William M. Connolley takes a more critical view. Connolley asks, “Everyone who has doubts gets to run their own re-analysis of the temperature record? Wouldn’t it be quicker if people just read the existing literature?” Most of the data used by Muller has been around for years, and so has his conclusion: that humans are rapidly raising the temperature of this planet by releasing carbon dioxide into the atmosphere. Greg Laden writes, “It’s over. The whole climate denialism thing, that is.” But some people will still say we’re wrong.
