I first wrote a doom–laden article for the Economist about carbon dioxide emissions trapping heat in the air in 1987, nearly 40 years ago. I soon realised the effect was real but the alarm was overdone, that feedback effects were exaggerated in the models. The greenhouse effect was likely to be a moderate inconvenience rather than an existential threat. For this blasphemy I was abused, cancelled, blacklisted, called a ‘denier’ and generally deemed evil.
