The Rufous Scrub-bird: will it have to move to Tasmania to survive? Allan Richardson

Finding new nests for birds threatened by climate change

Rufous Scrub-birds have been calling loudly from the mountains of eastern Australia ever since Australia parted from Gondwana 65 million years ago. They are still there today – as noisy as ever, though…

Explainer: back burning and fuel reduction

The recent surge of bushfire disasters has introduced fire-fighting tactics to everyday language. Two important approaches that use fire to fight fire are “back burning” and “fuel-reduction burning”. Unfortunately…

Vale ‘Gump’, the last known Christmas Island Forest Skink

Among the most haunting and evocative images of Australian wildlife are the black and white photographs of the last Thylacine, languishing alone in Hobart Zoo. It’s an extraordinary reminder of how close…

We mustn’t waste water while taking action on climate change

Should we pick and choose our climate strategies based on how water-wise they are? As our new research published in Climatic Change shows, some activities aimed at tackling greenhouse emissions can also…

To grow agriculture in Australia, farmers need to think like miners

It’s perhaps fitting that mining magnate Andrew Forrest is in the vanguard of a move to position Australia as a major food supplier to China. Fitting, because if the plan is to work, Australian agriculture…

Carbon pricing is still the best way to cut emissions, if we get it right

The Coalition government has recently axed Australia’s carbon “tax”, leaving us with no carbon price. Alternatives include the government’s “Direct Action” plan, or Clive Palmer’s proposed emissions trading…

What our love affair with coffee pods reveals about our values

Mornings just aren’t the same. Late sleepers, once troubled only by the quiet gurgle of the boiling kettle, are now shaken from their slumber by the guttural sounds of steaming water being forced through…

Land clearing laws bring out worrying libertarian streak

Last week, an environmental officer, Glendon Turner, was allegedly shot and killed by a farmer near the town of Moree in New South Wales. A 79-year old man, Ian Turnbull, has been charged with Mr Turner’s…
Fishing of potato rock cod is totally banned in Queensland waters. Better regulation might avoid similar bans for other species. Mark Priest

How ecosystems can keep their fish, and we can eat them too

Tighter bag limits for fishing could be the key to ocean conservation, according to new research showing that limiting fishing across entire regions can offer better protection than using marine reserves…
The methane-detecting four-wheel-drive, measuring emissions around Queensland and NSW coal seam gas wells. Tests were also done upwind of each site to avoid cows or other methane sources skewing the results. CSIRO

Coal seam gas emissions lower than US: first Australian study

One of the most common questions Australians ask about coal seam gas is whether the gas wells leak – and if so, how much? In the first Australian study of its kind, new CSIRO research now gives an indication…
Indigenous land owners weren’t consulted in the past about the creation of Western Australia’s huge Ord River irrigation scheme – but a recent agreement offers a more positive example for developing other parts of northern Australia. Pete Hill/Flickr

Lessons from the Kimberley on developing Northern Australia

We are very happy to have got this far. We have had our disagreements but we have managed to work through them and now we are all getting on with the job. We have learnt a lot through the process. Standing…
Clouding the issue: the latest analysis of the impact of the Renewable Energy Target contradicts previous reports. Bo-deh/Wikimedia Commons

How does the Renewable Energy Target affect your power bills?

The review of the Renewable Energy Target is due to be handed to the federal government any day now, yet amazingly there are still conflicts over whether the policy makes electricity more or less expensive…

Carmichael mine is a game-changer for Australian coal

The Carmichael coal project, approved this week by environment minister Greg Hunt, is unprecedented in its scale, and also represents a significant shift in Australia’s coal industry. If the mine goes…

New Zealand’s Southern Alps have lost a third of their ice

A third of the permanent snow and ice of New Zealand’s Southern Alps has now disappeared, according to our new research based on National Institute of Water and Atmospheric Research aerial surveys. Since…
Stuck in the past: Sydney’s rail system is crying out for investment, but Australian approaches to fares and funding are out of date. Chris Hale

Public transport has been let down by our reluctance to pay for it

Public transport has a problem with money. Campaigners often argue that mass transit is a public good in its own right, and hence should be very cheap or even free. Mainstream media and even many self-proclaimed…

Our pollution reached Antarctica long before the great explorers

Lead pollution from Australia reached Antarctica in 1889 – long before the frozen continent’s golden age of exploration – and has remained there ever since, new research shows. In our study, published…

The ‘pre-Holocene’ climate is returning – and it won’t be fun

A string of events earlier this year provided a sobering snapshot of a global climate system out of whack. Europe suffered devastating floods, Britain’s coastline was mauled, and the polar vortex cast…

Environmentalists have a right to protest – but not at all costs

Here is a tough question – what are the limits of legitimate protest? As Lord Keynes is famously reputed to have said, everything depends on everything else. What is protest? What is legitimate? I’m going…

What should we do with Australia’s 50,000 abandoned mines?

Wandering around Australia, you might want to watch your step — the country currently has more than 50,000 abandoned mines. Some represent a significant threat from contamination; others may pose safety…
Battery costs can make up a quarter of the cost of an electric car such as this Tesla Model S. Shal Farley/Flickr

Affordable batteries for green energy are closer than we think

At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when…
