If the question is do people (in the Liberal Party) believe that human beings are the main cause of the planet warming, then I'd say a majority don't accept that position.

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.

I must say that when I first learned of the existence of the Australian Greenhouse Office, I assumed it was responsible for supplying tomatoes to the Parliament House kitchen. But, no, as I soon learnt as industry minister, it was in fact a government funded redoubt of veritable soldiers in a war against carbon dioxide. The zealotry and obsessive passion of these warriors in the battle against the apparent evils of carbon dioxide remains a curiosity to me. After fighting these people for three years as industry minister, I really did wish they would just go away and grow tomatoes.

Making the documentary was an extraordinary experience and it really hit home to me the quasi-religious nature of this anthropogenic global warming cause. These people really have found religion.

If the question is do people (in the Liberal Party) believe that human beings are the main cause of the planet warming, then I'd say a majority don't accept that position.

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 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.
