Senator ROBERTS (Queensland) (17:02): I seek leave to make a short statement. The DEPUTY PRESIDENT: Leave is granted for one minute. Senator ROBERTS: In the last 170 years we have seen a phenomenal improvement in living standards right around the world, particularly in the developed world. That has been due to one thing—that is, the relentless decrease in energy prices in real terms. In the last 15 years in Australia we have seen the reversal of that. In Spain and England we have seen that, for every so-called renewable energy job, 2.2 to 3.7 productive jobs have been lost from the real economy due to energy prices. This is ridiculous. This is antihuman. It is against civilisation. I make a challenge that there has never been any empirical evidence proving that human carbon dioxide causes climate variability. I would be very pleased to receive any specific empirical evidence of human carbon dioxide causing that. I would like the paper, the title, the specific page number and the data. (Time expired) The DEPUTY PRESIDENT: The question is that general business notice of motion No. 88, in the name of Senator Waters, be agreed to.
