The climate-sceptic right has long had a frustrating tendency to come up with nonsense arguments that superficially sounds like common sense. In 2013, a certain Alexander Boris de Pfeffel Johnson wrote in the Telegraph that, as he could see snow falling outside his window, it felt like we were heading for a mini-ice-age. Anybody who knows anything about climate science shook their head with a sigh.

Today the same Alexander Boris de Pfeffel Johnson, now Prime Minister, is launching a £4billion 10-point plan for a Green Industrial Revolution. OK, that is not enough cash, pales into insignificance compared to the investments in France or Germany, and I could quibble over the priorities, but the 180° change of heart cheers my very soul. The decision to ban the sale of petrol or diesel cars by 2030 is, alone, an incredibly bold statement of intent that should not be sniffed at.

So I welcome today’s announcement – I just hope that this is the only the start, not the entirety, of the Green Industrial Revolution.
