Bjorn Lomborg has come out in favor of a carbon tax and additional spending to deal with climate change. Now everyone is all excited that a climate "skeptic" has made a u-turn.
But Lomborg wasn't really a skeptic on the science, he just believed that there were other environmental challenges that were more important, or at least more easily solved, that affect the lives of many more individuals than warming. I don't consider this a true reversal, as it sounds like his new book will at least consider different ways of handling the fallout from climate change, as opposed to the one way that most adherents of climate change orthodoxy espouse: a return to the pre-technological ages.
