Ready for a little peek behind the editorial decision-making curtain at the Wall Street Journal? On Friday, the paper published an op-ed disputing anthropogenic global warming, on the strength of its being signed by 16 scientists. Sixteen, wow, that's a lot! Except that in May 2010, 255 members of the National Academy of Science wrote an op-ed laying out the actual facts about global warming, and the WSJ turned it down. (It was published in Science instead.) Wait, is it possible this isn't about the number of scientists at all??
