Rabbits destroy huge numbers of critical regenerating seedlings over more than half the continent. This has devastating flow-on effects for the rest of the ecosystem. So how do we control them?

Australia is now taking a 2050 target to Glasgow, but this does not mean we are fulfilling the undertakings we made in Paris.

After soil, water and food, microplastics have now entered the atmosphere, where they influence the climate system and may even change atmospheric chemistry. Laura Revell, Senior Lecturer in Environmental Physics, University of Canterbury Licensed as Creative Commons – attribution, no derivatives.

If we all collect and understand scientific data as citizens, we’ll be a step closer to a society able to make better collaborative decisions. Hugh Possingham, Professor, The University of Queensland Licensed as Creative Commons – attribution, no derivatives.

We need to urgently address the gaps in Australia’s capacity to manage disasters that have widened since climate adaptation was relegated to the back burner.

In countries where the right to a healthy environment is part of domestic law, court decisions are already resulting in stronger climate action. Nathan Cooper, Associate Professor of Law, University of Waikato Licensed as Creative Commons – attribution, no derivatives.

Māui dolphins are at risk of extinction. With a marine mammal sanctuary in place since 2008, the risk from fisheries is now largely under control. It’s time to take other threats more seriously.

Nations must work with their neighbours to manage and protect species and human rights. An international environmental deal called the Escazú Agreement shows what’s possible. Rebecca K.

International cooperation is crucial if we are to have the best chance of limiting global warming. So who are the key players? Matt McDonald, Associate Professor of International Relations, The University of Queensland Licensed as Creative Commons – attribution, no derivatives.

Australia’s top economists say Australia can’t “free-ride”, allowing others to cut emissions while it gets the benefits. Peter Martin, Visiting Fellow, Crawford School of Public Policy, Australian National University Licensed as Creative Commons – attribution, no derivatives.

Setting this as our target would see Australia become a valued and relevant party to negotiations at Glasgow, rather than a resented freeloader. So how do we get there?

A new analysis shows almost all emissions reductions will be the result of state government policies, and will have virtually nothing to do with the federal government.

A new modelling approach improves projections of Antarctica’s future ice loss. It shows a low-emissions scenario would avoid the collapse of West Antarctica’s ice sheet and limit sea-level rise.

Japan, South Korea and China are all moving away from overseas coal financing. For Australia, the writing is on the wall – the clean energy transition is inevitable.

Populations of noisy miners have boomed since colonisation, and today they’re a huge threat to other native birds. 45 attempts to cull them in 30 years have left us with more questions than answers.

Nationals’ concerns about the effects on regional Australia are legitimate, but greater forces in favour of a net-zero emissions target will likely push the policy over the line.

Extreme weather is behind much of the crisis, but it will make the transition to new energy sources more complicated. Lurion De Mello, Senior Lecturer in Finance, Macquarie University Licensed as Creative Commons – attribution, no derivatives.

Offsetting may be controversial, but we need it to reduce emissions. Here’s how it can be done with integrity. Alison Reeve, Deputy Program Director, Energy and Climate Change, Grattan Institute Licensed as Creative Commons – attribution, no derivatives.
