WHEN the history of the global warming scare comes to be written, a chapter should be devoted to the way the message had to be altered to keep the show on the road. Global warming became climate change so as to be able to take the blame for cold spells and wet seasons as well as hot days. Then, to keep its options open, the movement began to talk about "extreme weather".
Part of the problem was that some time towards the end of the first decade of the 21st century it became clear that the Earth's average temperature just was not consistently rising any more, however many "adjustments" were made to the thermometer records, let alone rising anything like as rapidly as all the models demanded.
So those who made their living from alarm, and by then there were lots, switched tactics and began to jump on any unusual weather event, whether it was a storm, a drought, a blizzard or a flood, and blame it on man-made carbon dioxide emissions. This proved a rewarding tactic, because people - egged on by journalists - have an inexhaustible appetite for believing in the vindictiveness of the weather gods. The fossil fuel industry was inserted in the place of Zeus as the scapegoat of choice. (Scientists are the priests.)
