There are more and bigger coral trout in parts of the Great Barrier Reef closed to fishing.
Fishing is a major threat to the Great Barrier Reef, but new research shows that areas closed to fishing just over a decade ago are home to bigger and more fish.
Clumps of thunderstorms are driving increases in rain over tropical oceans.

For a long time climate models have forecast increasing rainfall in tropics. Now we know part of the reason: clumpy thunderstorms.

A new report aims to establish exactly what we do and don't know about the effects of dredging on the Great Barrier Reef, and suggests that managing fine sediments will be one of the biggest challenges.
The debate around coal seam gas exploration is highly politically charged, so it’s important to have an accurate picture of what exactly is proposed.
Is Christian Democratic Party leader Fred Nile correct when he says that 53% of Australia's landmass is under current exploration licence for unconventional mining?

Natural disasters are becoming more frequent, with more people with less money exposed to a greater number of hazards.
Did foxes ever make it to Tasmania? DNA evidence suggests they did.
New evidence suggests there no foxes in Tasmania. Were there ever? Even if there weren't, the state's multi-million dollar fox hunt was worth it to save wildlife.
The Franklin River which would prove to be Fraser’s environmental undoing.
Malcolm Fraser may be remembered for his failure to intervene in the Franklin Dam campaign, but he otherwise led a government distinguished for its environmental action.
NSW Labor has promised a Great Koala National Park to protect koalas, but what about more insidious threats to the environment?
NSW has nearly 300 threatened animal species, including koalas and pygmy-possums. Yet we still don't know the government's plans in one area that could pose a serious threat to NSW's wildlife.
Rio Tinto’s Mount Thorley-Warkworth mine in the Hunter Valley, which looks set to expand further. The NSW planning department says it would “not be reasonable” to require Rio Tinto “to completely or even partially backfill the final void”.

There are hundreds of derelict mine sites across New South Wales – and the state planning department has admitted it is "not aware of the total size" of large mining voids currently being left behind.
Burning fossil fuels is still the greatest source of greenhouse gases.
In the lead up to climate meetings in Paris at the end of the year, countries will release draft targets - the framework of a possible global climate deal. Follow our interactive map as we track these targets.
Is Bill Gates' desire to help tackle the world’s problems compatible with his foundation’s huge fossil fuel investments?
The Gates Foundation is being urged to dump its sizeable fossil fuel assets. Bill Gates cares deeply about world health and development, both of which are affected by climate, but will his charity divest?
Unless community concerns are heard and responded to, the NSW coal seam gas industry will keep running into road blocks.

Whether you're a supporter or opponent of coal seam gas, the looming New South Wales election will decide the industry's future in the state. So what are the three key issues to watch?
It’s hard to know for sure what role climate change played in the intensity of Cyclone Pam.

A causal relationship between cyclone behaviour and anthropogenic global warming is a very real possibility. But most climate scientists hesitate to attribute any single event to global warming.
Could Tiger Quolls replace pet cats?

Senator David Leyonhjelm has proposed keeping native animals as pets as conservation. But that would do effectively nothing for wildlife in the wild.
The Bill and Melinda Gates Foundation has been urged to join the fossil fuel divestment movement.
The Guardian's divestment campaign is targeting charitable research trusts. John Quiggin says they have a moral duty to divest fossil fuels, regardless of the temptation to research technological climate fixes.
China’s government says it plans to tackle smog, but has also moved to shut down criticism on the issue in the wake of a popular online documentary.
Under the Dome, a hugely popular online documentary about China's smog crisis, could be as influential as 1962's US pesticide exposé Silent Spring - but only if Chinese officials allow debate to flourish.
Recent increases in land clearing threaten Queensland’s biodiversity.
Land clearing in Queensland has tripled since 2010 after wind backs to regulations.
The University of California is the world’s leading university on dealing with climate risk to its investments - most others have a long way to go.
Do universities deserve praise for pledging to drop fossil-fuel investments, or for actually doing it? Former Liberal leader John Hewson, who leads the Asset Owners Disclosure Project, says only the latter.
Cyclone Pam has left a shell of Uwen Garae’s home in Port Vila, Vanuatu.
The devastation to Vanuatu left in the wake of Cyclone Pam shows small islands in the Pacific need a climate insurance scheme, similar to what has been achieved in the Caribbean.

New plans to ban dredging on the Great Barrier Reef and dump dredge spoil on land won't save the reef.
Destruction caused by Cyclone Pam is visible on the outskirts of Port Vila.

We now have more people, infrastructure and assets exposed where tropical cyclones make landfall.
It’s not always as ostentatious as Dubai, but our coastlines are home to ever-growing numbers of manmade structures.
Urban sprawl has spread to the sea, as more and more man-made structures are being built along the world's coastlines. Just as we do on land, we need to think about how to build sustainably at sea.
Indigenous rangers like Yugul Mangi senior women (from left to right) Edna Nelson, Cherry Daniels and Julie Roy, are crucial guardians of the outback environment.
Remote Indigenous communities aren't just places to live - they are also crucial for supporting ranger programs and other projects that protect the environment in areas that might otherwise go untended.
Money spent on helping consumers reduce demand means less money spent on substations and other infrastructure.
Incentives for cutting peak power demand are cheaper than building ever more infrastructure and sending power bills ever higher. The industry has a chance to embrace this new approach - but will it?
Could devils help solve our feral cat crisis? The devil might be in the detail.
Proposals to reintroduce Tassie devils to the Australian mainland have argued devils could help control feral cats. But new research shows there's no simple answer.
