Letter in the TWT this week referring to "the extravagant claims made by a section of the screaming popularist (sic) media", ie, the fact of global warming, which has been "exposed by a prominent Australian geologist, David Archibald". As far as I've been able to find out, Mr Archibald works for the oil exploration industry; his theory that sunspot activity means the weather will be getting colder has not been published in any peer-reviewed scientific journal, but in the climate sceptic front journal
Energy and Environment, in what appears to be a vanity-pressed book, and in
various places online. "I am no expert on climate", admits the letter writer; it appears Mr Archibald isn't, either.
