One vet suggested bushfire smoke had killed the smoky mouse – and asked, in a nod to the species' name, if this was a case of "death by irony". Andrew Peters, Associate Professor of Wildlife Health and Pathology, Charles Sturt University Licensed as Creative Commons – attribution, no derivatives.

When the post-bushfire rains finally arrived, the situation for many fish species went from dangerous to catastrophic. A slurry of ash and mud washed into waterways, sending oxygen levels plummeting.

After the bushfires, we went looking for endangered corroboree frogs. Normally, they respond to our calls. But at some sites, the ponds were silent.

Electric vehicles are still relatively expensive but a trial to help them power the national grid in times of need could see owners being paid. That could make them a lot more attractive.

Three quarters of WA's Stirling Ranges national park now experience fire cycles twice as frequent as species recovery rates. Kingsley Dixon, John Curtin Distinguished Professor, Curtin University Licensed as Creative Commons – attribution, no derivatives.

The last time global carbon dioxide levels were around 400ppm was four million years ago. On average, the world was 3℃ warmer, but in high northern latitudes, it was up to 14℃ warmer than today.

It's painfully clear nature is buckling under the weight of farming's demands. There's another way – but it involves accepting nature's limits. Sue McIntyre, Honorary Professor, Australian National University Licensed as Creative Commons – attribution, no derivatives.

Koalas are notoriously difficult to detect. Traditional methods are costly and labour intensive. So we found a more efficient way to locate koalas in eastern NSW, using drones. Ryan R.

As the world warmed from the last ice age, a rise in carbon dioxide levels stalled for nearly 2,000 years. That's always puzzled scientists, but now they think they know what happened.

As the planet continues to warm, extreme weather events such as heatwaves and heavy rainfall are becoming more frequent, intense and longer, according to global weather data.

The federal government today announced $1 billion plan to divert more than ten million tonnes of waste from landfill. But waste management is about more than just recycling.

Heatwaves have become longer, hotter and more frequent. This trend is accelerating from climate change. Sarah Perkins-Kirkpatrick, ARC Future Fellow, UNSW Licensed as Creative Commons – attribution, no derivatives.

Some coal workers have the right skills and work in the right location to get a job in renewables. But many, such as semi-skilled machine operators, cannot.

The Berejiklian government must step up to the challenge of saving koalas in NSW from their predicted fate: extinction in the wild by 2050. Dr Christine Hosking, Conservation Planner/Researcher, The University of Queensland Licensed as Creative Commons – attribution, no derivatives.

Australia abandoned its moral obligations under Kyoto. By carrying our mistakes into the Paris deal, we risk firming our status as a global climate pariah.
