John Redding (The Australian, Last Post, 14/12) calls the ABC’s coverage of global warming “shamelessly one-sided”. Agreed; and that would be because the science is one-sided. Does he expect the tiny rump of scientists who reject it to be given equal time with the vast bulk who accept it? Would he also put the views of flat-earthers on an equal footing with those who know it as round? Just because there are several views on a topic does not mean they are all equally valid, or warrant equal airtime.
