Greens call for modelling of hotter planet

Adam Bandt says our emissions reduction target will put the world on track to warm by three degrees

Australia's emissions reduction target will put the world on track to warm by three degrees Celsius, the Greens say.

The minor party's lone MP Adam Bandt has introduced a bill to parliament to make the Climate Change Authority model what such a world would be like.

"The Australian people need to know the Morrison government's current climate targets will take us into a 3C world, with catastrophic consequences for Australia," he said on Monday.

"We're already seeing the severe impacts of a 1C world, with the climate crises driving the fire emergency and record drought."

The possible temperature rise is based off analysis from Climate Analytics and the New Climate Institute's climate action tracker.

It looks at action taken by governments across the globe, tying in emissions reduction projections, targets and science linked to different temperatures.

Scientists making policy recommendations to leaders through the United Nations say global temperatures have already increased by about 1C, and are now putting their efforts towards halting warming at 1.5C.

Mr Bandt noted Scott Morrison has changed his tune towards the debate, with the prime minister now saying climate change is real and the government is doing its bit.

"If that's right - and it's not - he should allow the Climate Change Authority to review the government's targets and tell Australia what it means to be on track for 3C."

The Morrison government is under pressure to do more to tackle climate change, with the debate now coming from wider sections of the community including investors, farmers and older Australians.

Former prime minister Malcolm Turnbull has joined those ranks, taking a swipe at the government for its lack of climate policy.

Mr Turnbull says Liberal Party members must be "loud Australians" on climate change, a reference to the "quiet Australians" Mr Morrison credits for his shock election win this year.

Asked about the comments during Question Time on Monday, Mr Morrison said the government was implementing emissions reduction policies that began under his predecessor.

Meanwhile, the government has handed its report on the state of the Great Barrier Reef to the United Nations for its World Heritage listing assessment.

The report acknowledges climate change as the major threat to the reef, but says the government is on track to tackle it.

The UN is also poised to host a major climate conference in Spain, where countries are being urged to increase their emissions targets.

To coincide with the conference the Investor Group on Climate Change has called on the government to develop a better strategy to help investors avoid the impacts of climate change.

The Carbon Market Institute has also released its updated strategy towards net zero emissions by 2050, saying a low-carbon future won't cut it.
