Graham Lawton helps perpetuate a common climate denier myth by saying that in the 1970s scientists were worried that we were about to plunge into another full-blown icy spell (6 July, p 38). But a literature review finds that, even then, global warming dominated scientists' thinking as one of the most important forces shaping climate (doi.org/bfz64r).
The editor writes:
It would probably have been better to say “a few scientists”.
