I have said consistently in my 16-and-a-half years in the parliament, I have always supported the party room's decision and the party room is the ultimate authority on these matters. I don't expect that to change.

I am not at all convinced that human emissions of CO2 are adding to global warming.... I remain to be convinced about the theory of anthropogenic global warming.

It presents a really compelling case against the whole theory of anthropogenic global warming. From my point of view, it is a theory that has completely corrupted public policy making in most of the developed world. It confronts all the dubious claims that the warmists have put out there.

I am flattered that Bob Carter should ask me to launch what I think is a significant new book on climate change. I have developed a very high regard for Bob in the years that I have known him. He has been a terrific and leading voice in combatting the scare mongering that we have all been subjected to on the theory of anthropogenic global warming.
