Yesterday the ABC’s Drum site published a piece by Alan Moran attacking mainstream climate science. It was the first of what is promised to be a week of pieces "commissioned from noted writers on the sceptic side of the climate science debate", apparently prompted by that site’s publication last week of a five-part article by Clive Hamilton on the campaign being waged against mainstream science by climate denialists.

Moran is obviously entitled to his views regardless of whether they are easily shown to be false. The question is more why they were given a run on The Drum without some basic fact-checking or balance. Moran’s article did not “balance” those of Clive Hamilton, who wrote on a specific aspect of the climate change debate in which he is professionally involved. Moran can at least claim – unlike Tom Switzer – that he has expertise on climate scepticism, having been working on the issue for the IPA for some time, including speaking at international conferences.
