Senator ROBERTS (Queensland) (14:33): My question is to the Minister representing the Prime Minister, Senator Cormann. In 2016, 2017, 2019 and 2020 I cross-examined CSIRO's climate research team on four presentations to me. That revealed CSIRO has never said carbon dioxide from human activity is a danger. CSIRO admitted today's temperatures are not unprecedented. Honourable senators interjecting— The PRESIDENT: Order! I asked repeatedly last week for interjections to not occur. They came from both sides of the chamber, and I might say they commenced on the opposition side. They should not have been responded to from the government side. I am going to ask for stony silence in the chamber, and I'm going to ask Senator Roberts to repeat his question so that the minister may hear it and address it. Senator Roberts, please recommence your question. Senator ROBERTS: My question is to the Minister representing the Prime Minister, Senator Cormann. In 2016, 2017, 2019 and 2020 I cross-examined CSIRO's climate research team on four presentations to me. That revealed CSIRO has never said carbon dioxide from human activity is a danger. CSIRO admitted today's temperatures are not unprecedented. CSIRO cited papers do not show that the rate of temperature rise is unprecedented. CSIRO has never quantified any specific impact from human carbon dioxide. CSIRO relied on non-validated, erroneous models. CSIRO relied on discredited papers. CSIRO showed little understanding of papers cited. CSIRO admits to no due diligence on reports on data. CSIRO allows politicians to misrepresent CSIRO without correction. Fifteen highly respected international scientists verified our conclusions. What is the basis for the government's climate and energy policies?
