Clive James is apparently a wiz at languages, and his intellectual life has always been in the humanities.
His lengthy piece decrying climate change "alarmists", run in The Australian today with much prominence, is plainly, to anyone who has read widely on the subject, as worthless and utterly unreliable and out of date as a poet's analysis of the current state of a field of science could possibly be. (It really feels like it was written 8 or 9 years ago, at the height of the question of the what the "pause" meant - not that serious scientists ever thought it meant that rising global temperatures had magically stopped.)
There's a reason we don't rely on poets to instruct us on whether vaccines are good public policy, or what form of cancer treatment to take, or if Einstein could really be right because his ideas don't make much intuitive sense. Fortunately, most know their limits.
I don't wish James ill - he's been a very funny man in his day - but it is true that such ill formed views are literally dying out.
