Editor's note

Donald Trump has made good on his threat to withdraw the US from the Paris climate agreement. In a speech overnight, he described the 2015 treaty as “simply the latest example of Washington entering into agreements that disadvantage the United States to the exclusive benefit of other countries”.

Trump expressed a desire to renegotiate the agreement - something that does not appear to be possible under its current terms, which calls for nations to make a series of escalating but non-binding climate pledges over the coming decades. And as Christian Downie writes, China and Europe are already stepping into the climate leadership void that Trump has left in his wake.

Meanwhile, Australia remains committed to reducing our emissions, although there’s little political consensus on the best way to go about it. Fortunately, a report published today by CSIRO has found Australia is flush with good options: it outlines four different pathways to cleaner and cheaper energy.

The US quitting the Paris climate agreement will only make things worse

Jonathan Pickering, University of Canberra

Some experts say it's better for the US to leave the Paris Agreement than white-ant it from within. But that ignores the damage that a US withdrawal would do to the fabric of global multilateralism.

The world would be better off if Trump withdraws from the Paris climate deal

Luke Kemp, Australian National University

If the US stays in the Paris deal but misses its targets, the deal could look like a sham. But if Trump carries out his threat to withdraw, the US veto would be gone, and other nations might step up.

The world's coral reefs are in trouble, but don't give up on them yet

Terry Hughes, James Cook University; Joshua Cinner, James Cook University

Tropical coral reefs can be saved from climate change and other pressures, but the window of opportunity is closing. And reefs are guaranteed to be markedly different in the future.

We have almost certainly blown the 1.5-degree global warming target

Andrew King, University of Melbourne; Ben Henley, University of Melbourne

Limiting global warming to 1.5℃ already looks out of reach, so where do we go from here?

Fossil fuel emissions have stalled: Global Carbon Budget 2016

Pep Canadell, CSIRO; Corinne Le Quéré, University of East Anglia; Glen Peters, Center for International Climate and Environment Research - Oslo; Rob Jackson, Stanford University

For three years, carbon emissions from fossil fuels have grown little or not at all, opening a window of opportunity to halt climate change.

Australia’s biggest emitters opt to 'wait and see' over Emissions Reduction Fund

Jayanthi Kumarasiri, Swinburne University of Technology; Nava Subramaniam, RMIT University

A survey of executives in high-emitting industries such as mining and electricity generation suggests they are not engaging with the government's flagship policy to cut greenhouse emissions.
