Do alarmists know the difference between weather and climate?

Until recently, those expressing scepticism about climate-change catastrophe have been hauled over the coals (or the renewables equivalent) for not understanding the difference between ‘climate’ and ‘weather’. The lack of global warming at the beginning of the 21st century was not to be taken, chided the warmists, as evidence that climate change was not happening. Weather was the passing phenomenon of each day: climate was the real, deep thing.

Now, however, the alarmists themselves have elided the two concepts, using the Australian bush fires as their cue. As Sir David Attenborough puts it: ‘The moment of crisis has come.’ They could be right, of course, but how could they really know? In this sense, President Trump is surely justified in warning, at Davos, against the ‘Prophets of Doom’. Prophecy is a different skill from an exact understanding of the here and now.

Mr Trump might usefully have talked about the Profits of Doom too.
