Senator DI NATALE (Victoria—Leader of the Australian Greens) (14:22): My question is for the Leader of the Government, representing the Prime Minister. On Thursday last week, the Bureau of Meteorology said that the drought that the Murray-Darling Basin was experiencing was 'the most severe in 120 years of records'. Minister, do you and the government accept the advice of the bureau and other scientific bodies that climate change is a significant contributor to current and future droughts?
