The plan to kill 2 million feral cats nationwide by 2020 makes for good headlines. But it's also a simplistic goal that won't necessarily deliver conservation benefits to native species.
China's refusal to take Australia's rubbish has started to bite, and it's clear we're not ready to deal with the consequences.
As soon as white colonists began farming sheep in Australia, they looked for a way to eradicate dingoes.
What do the recent Townsville floods and Tasmanian heatwave have in common? Both were caused by weather systems that stayed put for days or weeks on end. And global warming could worsen that trend.
It's easy to whip out the fly spray, but our fondness for pesticides can bring knock-on effects such as increased resistance, and harming beneficial insects in and around our homes.
Wander in the dark forest and you might spot the radioactive glow of the ghost fungus.
For as little as $4 a day Indian workers process dangerous, toxic waste by hand. This unregulated, highly polluting industry is hidden away from police eyes.
We can't make it rain. But you are already helping if you don't use more water than you need. And you can talk to your parents about the planet getting warmer, because the heat makes drought worse.
Recognising animals as sentient means welfare laws must consider animals' feelings as well as their physical conditions.
Ecosystems can collapse suddenly and totally. Frozen zoos are trying to create archives of genetic material to prevent total extinctions.
The natural world depends on insects to function, but they may be the next casualty of climate change.
Australia's subtropical regions are drying, but if we can slow the global temperature rise then rainfall should increase again.
A NSW court's decision to rule out a coalmine on the basis of climate change could signal a turning of the tide in an arena where environmental litigants have previously struggled to gain traction.
A new report predicts that one-third of the ice in the Himalayas will melt, even if we contain global warming to 1.5C. So what does that mean for the flood-prone valleys below?
Walking towards this tree, which grows only on a select few mist-shrouded mountainsides in Queensland, can feel like stepping into a prehistoric dinosaur-filled fantasy.
Everyone knows the Great Barrier Reef is in peril. But a continent away, Western Australia's Shark Bay is also threatened by marine heatwaves that could alter this World Heritage ecosystem forever.
The Black Saturday fires transformed the way Australia responds to bushfires.
Black Saturday in 2009 was Australia's worst bushfire tragedy. But climate projections predict more bushfire danger in the future, threatening our water supplies as well as homes.
In the years after Black Saturday, climate adaptation research was in full swing, creating knowledge in how to deal with the risks. But a series of funding cuts have left this research in decline.
Victoria's Country Fire Authority was founded in the aftermath of a previous bushfire tragedy – the 1939 Black Friday blazes. But its creation was a bigger political saga than many people realise.
Climate change is making Tasmania more vulnerable to brutal fire conditions.
Climate scientist predict that the combined effect of ice loss in Greenland and Antarctica will be more extreme weather, with impacts on agriculture, infrastructure and human life itself.
The flood zone around Townsville extends for hundreds of kilometres, making monitoring difficult even from the air. But scientists are testing a new satellite method that can peer through the clouds.
Despite bans around the world, there's no empirical evidence sunscreens cause coral bleaching.
A scathing report about the Murray Darling Basin Authority highlights the importance of climate change risks to public sector companies.
