Mr President, I ask a supplementary question. I thank the minister for that update on the science and ask: isn’t it the case that it has been the commonly held view in Australia for some time that carbon pollution—or, as it is sometimes called, greenhouse gases—is what is causing climate change? Wasn’t it in fact the previous Prime Minister, Mr Howard, who said that there is ‘no doubt’ that greenhouse gases are having an adverse effect on the environment? Has there been any recent suggestion that Mr Howard was wrong in making that claim?
