N. Ford (The Australian, Talking Point, 22/1) counts three sources of information on climate change: mainstream science (which Ford provocatively calls “green”), the dissenting minority (mislabelled “sceptic”, as if all scientists were not), and “green propaganda”. But oddly, Ford omits the obvious fourth source, which is the politically-motivated anti-AGW publicity which floods the blogosphere, talkback radio and the opinion pages of The Australian. Only the two scientific sources are relevant to the debate; of those, the fringe view comes a distant second.
