Conditional commitments are promises to raise emissions reduction efforts, depending on what others do. It could be a big incentive for Australia. Katie Steele, Associate Professor in Philosophy, Australian National University Licensed as Creative Commons – attribution, no derivatives.

There is no doubt we need to stop emitting fossil carbon. But if we fixate on replacing fossil fuels with renewable energy and don’t also reduce consumption and energy waste, we risk failure.

Seabirds journey vast distances across the Earth’s seascapes to find food and to breed. This means their biology, particularly their breeding success, can reveal what's happening in our oceans.

The court described climate change as 'the greatest inter-generational injustice ever inflicted by one generation of humans upon the next'. Laura Schuijers, Research Fellow in Environmental Law, The University of Melbourne Licensed as Creative Commons – attribution, no derivatives.

The arguments in favour of radical emissions reduction action, including the personal financial risks, grow more compelling by the day.

Electric cars are being touted as the best way to reduce emissions from transport. But a climate policy that relies on individuals paying for new technology runs the risk of aggravating inequities.

Saving our threatened species shouldn't be seen as a cost, but rather a very savvy investment to ensure the support systems sustaining life on Earth remain intact.

Some Australian states have committed to 100% renewable energy targets, or even 200% renewable energy targets. But this doesn’t mean their electricity is, or will be, emissions free. James Ha, Associate, Grattan Institute Licensed as Creative Commons – attribution, no derivatives.

These hefty dinosaur birds stand as tall as humans, enough to dissuade most from getting too close. But how would they fare against each other in a fight? A wildlife expert places her bet.

None of Australia's highest-emitting energy firms are fully or even closely aligned with global climate goals. Just one goes even partway, and five appeared to be taking no action at all.

The opportunity won’t last forever. Countries that move first will gain an advantage in new industries, technologies and export markets. Those that wait may never catch up.
