‘Case closed.’ No ‘doubts’ and no appeal. These are revealing words. Climate change has long since ceased to be an issue to be addressed, or a set of challenges to be overcome. It is now the revealed truth, the God-like judgement around which we must organise the entirety of societal life. To question this truth is tantamount to apostasy. Hence Lynas calls for any remaining heretics to be censored, urging Facebook and Twitter ‘to look at their algorithms and policies’ to root out ‘climate misinformation’.

Indeed, those daring to question any aspect of the alarmist narrative are now routinely dismissed not as heretics, but as ‘deniers’ – a term which morally equates those who question, say, certain decarbonisation policies with anti-Semites who deny that the Holocaust happened.

Take the experience of statistician and sceptical environmentalist, Bjorn Lomborg. Earlier this year he was invited to give a public lecture at Duke University, only to be met by high-profile calls for it to be cancelled from Duke professors and assorted climate activists. Duke held its nerve, and the lecture went ahead, but not without Lomborg being denounced as a ‘professional climate denier’ – and all because he questions the economic wisdom of certain aspects of climate-change policymaking.
