Over the past year, Amazon’s list of global-warming bestsellers has been wholly dominated by sceptics, with my own book The Real Global Warming Disaster standing for months at number one. At the end of last month, however, all the more recent sceptical books were suddenly removed from the list. My own volume, Andrew Montford’s The Hockey Stick Illusion, Bob Carter’s Climate: The Counter Consensus and others have all vanished from the list, so that it is now dominated by titles pushing the prescribed pro-warming line.
