Senator DI NATALE (Victoria—Leader of the Australian Greens) (14:23): Minister, I want to quote you something from the International Monetary Fund's report last week: 'There's growing agreement between economists and scientists that the risk of catastrophic and irreversible disaster is rising, implying potentially infinite costs of unmitigated climate change including, in the extreme, human extinction.' Minister, do you accept the IMF's testimony or do you believe it is another example of negative globalism?
