Mr Mullins also said: 'Let's draw a line under it all. I'd love to see the Greens, Labor, the coalition and crossbench get together and say this is a climate emergency. Let's start now and take action on the base cause, which is the burning of oil, coal and gas. Let's look after our future.' Minister, just like Prime Minister Howard reached across the political divide after the Port Arthur massacre, will your government accept we're in a climate emergency and take action on climate change?
