The Australian Greens Leader, Senator Christine Milne, moves a motion in the Senate to recognise the latest findings of the Australian Bureau of Meteorology and calls on the Abbott Government to reduce Australia's vulnerability to extreme weather events by taking action on climate change.

The Australian Greens Leader, Senator Christine Milne, calls on the Abbott Government not to obstruct climate negotiations in Lima and to set a national emissions target consistent with the Climate Change Authority's (CCA) recommended range.

The Greens are warning Victoria will suffer devastating job losses and hits to the local economy if a plan to phase out the dirtiest power stations isn't put in place before they fail.

"The closure of old Victorian power stations is inevitable," said Australian Greens Leader Christine Milne.

"With huge excess power supply and last century technology, they will become junk assets within the next five years, unable to compete with cheap, cleaner energy.

Australian Greens Leader Christine Milne says it is a complete deception for Tony Abbott to claim he's acting on climate change with $10 billion in the Clean Energy Finance Corporation, when he plans to abolish that very instrument, and when his government describes it as a complete waste of taxpayers' money.

"This is not a cheeky sleight of hand. This is Australia's climate denying Prime Minister telling outright lies to world leaders and international media," said Senator Milne.

Australian Greens Leader Christine Milne says Joe Hockey can't expect to grow Australia's economy with policies that deepen inequality and worsen global warming.

"Climate has stolen the show at the G20, in spite of the Abbott government," said Senator Milne.

"Joe Hockey and Tony Abbott are completely wedged between their big business mates who want to carry on polluting for profit, and the world leaders who've come to Australia declaring it's time for a massive shift.

President Obama's realism on global warming has shown up the small minded Prime Minister of Australia, says Greens Leader Christine Milne.

"Barack Obama has shown just how small and last century Tony Abbott is," Senator Milne said.

"The G20 is meant to be addressing the overwhelming problems of our age but Tony Abbott is showing what a small minded and insignificant player he is by whining about domestic politics instead.

The leaders of the Australian and New Zealand Green parties are calling on their respective governments to take action on climate change and inequality at the G20 meeting in Brisbane this weekend - topics that are absent from the agenda of the meeting of the world's richest nations.

"The Prime Ministers of our two countries may not be prepared to talk about the issues that are overwhelming the planet, but the Greens are. So are other world leaders. As the G20 host, Tony Abbott needs to get real," said Australian Greens Leader Christine Milne.

The Australian Greens are congratulating the US and China on their agreement to act on global warming and say it's not too late for Australia to get on board.

"This should be a massive wake-up call to Tony Abbott. His continued climate denial and his destruction of the environment is reckless," said Greens Leader Christine Milne.

"Tony Abbott is so busy unwinding Australia's climate policies that he failed to notice the global economy is changing around him. He is risking billions of dollars in investment and thousands of jobs.
