Senator ROBERTS (Queensland) (14:26): My question is to Senator Cormann, representing the Prime Minister. For the anthropogenic-global-warming hypothesis to be accepted scientifically, it must be based on physical empirical data. During my meetings with the CSIRO it was confirmed that CSIRO relies only on erroneous, unvalidated computerised climate models, not physical data. This is the third admission of CSIRO's lack of empirical evidence proving causation. Both types of climate models have repeatedly failed to match physical data and observations, yet CSIRO has allowed this government to take confidence in climate models and that has led to policies economically destructive on the Australian economy. Senator Cormann, will you support an inquiry that would analyse and assess quantitatively the accuracy and levels of confidence in CSIRO's climate models?
