The tactic of demonising dissenters from the global warming orthodoxy has a long and dishonourable history now, and I'm sure that readers scarcely need me to recount the instances of bad behaviour that have made it to the public record. I was struck by the parallels between these stories and the experiences of Professor Joseph Meirion Thomas, a cancer surgeon who had the temerity to write a series of articles questioning certain aspects of the way health services are run in the UK.
The resultant Twitter storm would have looked entirely familiar to BH readers, with GPs and nurses all over the country flinging vulgar abuse at the good professor. This probably all falls under the heading of "free speech" (although also under the heading of "bad manners"), but as ever with these things there were less reputable ideas floating around, with one GP trying to organise a complaint to the General Medical Council and, in a painful echo of Andrew Dessler's contemptible behaviour during the Bengtsson affair, a GP from Fulham asked if the professor was "unwell". A letter describing Meirion Thomas as "vile" and "evil" was circulated to doctors in the area where the professor worked.
