The Australian Greens have backed a statement by 24 prominent Australians calling for "emergency-scale action" on dangerous global warming.

Australian Greens Deputy Leader, Senator Larissa Waters said, "We are running out of time to save our Great Barrier Reef, protect our rural communities, safeguard our way of life and avert a global warming catastrophe.

"Dangerous global warming is not just an environmental issue. It threatens our children's future and it's unfolding before our eyes.

The Government's announcement today of $100 million per year for green cities taken from Clean Energy Finance Corporation, is its third attempt to rebadge existing CEFC funding while cutting $1.3 billion from ARENA and leaving fossil fuel subsidies untouched. 

Greens Sustainable Cities spokesperson, Scott Ludlam, said:

"Green cities are a massive opportunity, not a cheap slogan. The Greens will continue to work for cleaner and more energy efficient neighbourhoods without the senseless sting in the tail that Mr Turnbull is inflicting today."

The Turnbull Government's $1 billion Reef Fund is effectively a cut from the Clean Energy Finance Corporation and is undermined by the Adani coal mine. 

Qld Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, said:

"This is a sneaky attempt by the Turnbull Government to try to distract from the damage it is doing to the Reef by approving coal mines to export out through the Reef and cook its corals.  

The Australian Greens are calling on Labor to rule out funding fossil fuel projects from the $5 billion Northern Australia Infrastructure Facility.

Qld Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, said:

“While Labor is putting aside a fifth of the fund for tourism, it hasn’t ruled out the other $4 billion of taxpayer money going to fossil fuel projects.

Labor's Great Barrier Reef water quality policy announced today fails to deal with the real cause of coral bleaching - the mining and burning of coal - does not provide enough funding, and dodges the tough issues like a cap on water pollution.

Scientists have today reported that coral bleaching has killed more than one third of coral reefs in the central and northern regions of the Great Barrier Reef.  

Qld Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, said:  

The Australian Greens condemn the Turnbull Government for overseeing the censorship of a UN climate change report to remove all mention of the Great Barrier Reef and call on Minister Hunt to explain his role.

Qld Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, said:

"The Turnbull Government will stop at nothing to cover up the devastating impact its inaction on global warming is having on our World Heritage Areas like the Great Barrier Reef and our magnificent Tassie Wilderness.

UNSW's world-leading research, announced today, which breaks a world record for solar efficiency, is funded through the Australian Renewable Energy Agency, which both the old parties want to cut by $1 billion.

Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, called on Malcolm Turnbull and Bill Shorten to scrap their plans to gut ARENA's funding.

Confirmation from Cape Grim that atmospheric carbon dioxide has reached 400 parts per million and another poll showing Australians want action on global warming show the old parties are out of touch with the science and the community.

"Reaching this dangerous threshold of carbon pollution in the atmosphere, the highest in human existence, must act as a global wake-up call," Senator Larissa Waters, Australian Greens climate change spokesperson, said.

The Australian Greens are calling for the release of a Climate Change Authority report recommending a carbon price, which the Authority decided to delay until after the election - a decision the Minister's Office said made it 'very happy'.

The Liberals' budget fails the environment and the Great Barrier Reef, cuts billions from clean energy and tops up the billions in hand outs to the fossil fuel industry with another $100 million.

Qld Senator Larissa Waters, Australian Greens climate change and environment spokesperson, said:

"Our Reef is suffering record coral bleaching driven by global warming but the Liberals are ripping out a billion dollars from clean energy, and funding for work on Reef water quality comes from cutting Landcare.
