Here is a great podcast recorded at the Sydney Institute – well worth a listen. Ian Dunlop, formerly a senior oil, gas and coal industry executive and now chair of Safe Climate Australia debates climate change with Ray Evans, former engineering academic and now Secretary of the Lavoiser Group.
Ian Dunlop acquitted himself very well, though he could have been stronger and more specific on the scientific detail: my impression was that he presented the level of scientific confidence on some basic questions to be much more equivocal than it is. He let Evans get away with a string of utterly false claims.
What a hopelessly weak performance from Ray Evans! No scientific case of any substance at all. A large soup of irrelevancies, mixed with a cup of straw men, and spiced up with a handful of downright false statements. Just goes to show how bereft of scientific argument the Greenhouse Mafia (of which Evans is a key member) really is.
