Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:35): Senator, there's a lot in that question, but I want to go back to the fundamental proposition: climate change is already affecting our agricultural production now. I read to you the figures earlier: ABARES modelling shows that climate change over the last 20 years has reduced the profitability of Australian farms by an average of 23 per cent, or around $29,200. No, you don't like the facts, and we know— The PRESIDENT: Senator Rennick? Senator Rennick: A point of order, Madam President: models are not facts. The PRESIDENT: Senator Rennick, that's a debating point. Minister Wong, please continue. Senator WONG: Senator Roberts, I understand your views on this. I disagree with them. What I would say to you is this: if you go and talk to a lot of Australia's primary producers, if you go and talk to primary producers in the Pacific— Senator Canavan interjecting— The PRESIDENT: Order! Senator Canavan. Senator WONG: or South-East Asia, the truth is people are already experiencing the impact of climate change on agricultural production. We might want to wish it away for ideological reasons, as Senator Canavan does, but— (Time expired) Honourable senators interjecting— The PRESIDENT: Order! I'm going to wait for silence. Opposition senators interjecting— The PRESIDENT: Order! I'm going to call an opposition senator, so those senators interjecting are wasting her time.
