Senator ROBERTS (Queensland) (12:28): I seek leave to make a short statement. The PRESIDENT: Leave is granted for one minute. Senator ROBERTS: So far we've had a global warming emergency, then a climate change emergency, then a climate catastrophe emergency. Now we've got a climate collapse emergency. One thing we've never had is any empirical scientific evidence showing that carbon dioxide from human activity needs to be cut. I first challenged Senator Waters to debate me and to provide the scientific evidence 10½ years ago. She immediately declined. She declined again in 2016 and again 602 days ago in the Senate. There has been nothing since, because there is no such evidence justifying the collapse of our electricity sector. What is threatened with extinction here is not our planet; it is our civilisation and it is science. The PRESIDENT: The question is that the motion moved by Senator Steele-John be agreed to.
