Senator WONG (South Australia—Minister for Finance and Deregulation) (14:31): I think we all know where Senator Joyce stands on the climate science. He is right out there. He has never believed that climate change is real. He has never believed that there is any risk. The PRESIDENT: Order! Senator Wong, you need to come to the question. Senator WONG: I am asked about the climate science. He has always believed, Mr President, that there is some sort of left-wing conspiracy. The PRESIDENT: Senator Wong, come to the question. Senator WONG: If he wants to know how much of an effect there is from policy on the climate, I say to him that if he does not want any domestic action on climate change, why is it that he supports a policy to deal with climate change? That is what Mr Hunt says yours does. If you do not think there is any need to take any action, why are you supporting policy which will be more expensive, which is supposed to achieve the same environmental outcome. Senator Brandis: Mr President, I have a point of order on direct relevance. The question was very specific. It was directed to a number of case studies of the alleged effect of the carbon tax on the Queensland environment. It was not about the Labor Party critique of the coalition's policy and you should bring the minister to the question. The PRESIDENT: The minister has one minute and six seconds remaining. I have drawn the minister's attention already to the question. The minister needs to address the question. Senator WONG: Thank you Mr President. I am responding to the proposition in the question. Senator Mason: You were asked a specific question. Senator WONG: Do you want to hear something or do you just want to yell? Would you like to hear something? You can just keep berating everybody. The PRESIDENT: Order! Senator Wong, ignore the interjections. They are disorderly. Senator WONG: The senator keeps wanting to have the argument across the chamber. The PRESIDENT: Forget about the interjections. Address your comments to the chair, Senator Wong. Interjections on my left are disorderly. When there is silence we will proceed. Senator WONG: The proposition that underlies the senator's question is that we should not take any action in Australia because we cannot single-handedly fix climate change. That is true. But the same proposition would apply to the coalition's policy, which costs more. The reality is, we know that the State of the Climate report has found that the concentration of greenhouse gases in the atmosphere is higher than at any other time in human history. There is a lot of science on this, Senator Joyce, and I accept it. (Time expired)
