Cyclone Pam struck the developing island nation of Vanuatu in March 2015. Poorer nations are more exposed to environmental dangers so are more concerned about impacts that might increase the risk.

Who cares more about environmental issues: people in rich countries, or not-so-rich countries? A survey suggests it's those in poorer places who are more vulnerable to issues like climate change.
As China realises the unpriced costs of coal power, such as air pollution, coal production is starting to fall.
China's falling coal production suggests the world is waking up to the real cost of coal, calculated as $5.3 trillion in a report released this week.
Countries should make pledges to fund low-carbon research - such as developing solar technology - and development as part of global climate talks.

Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
It takes time, but this is how a real consensus is built.

There is a way for governments to find out the consensus on global issues such as climate change. But it involves painstaking, complex work, and an end to the adversarial clash of competing ideologies.
The states could ‘top up’ renewable funding to encourage development.

With the federal cuts to the renewable energy target, the states are stepping up to fill the gap.
You need to take a wider view to work out the true greenhouse emissions from nuclear power.

Nuclear power isn't 'zero-emission', as many proponents claim. Factor in uranium mining, power plant construction, and other factors and it has similar emissions to wind power. But that's still lower than fossil fuels.
A flood plume containing sediments, nutrients and pesticides flowing onto the Great Barrier Reef from Bundaberg.

Successive plans to curb the sediments, nutrients and pesticides flowing into the waters around the Great Barrier Reef have fallen short, leaving the corals that call the reef home highly vulnerable.
The Great Artesian Basin is a source of water in many areas of inland Australia.
Recent water leaks related to coal seam gas development in New South Wales raise more concerns about the industry's impact on groundwater.
Has any other country achieved a greater reduction than Australia in the intensity of their emissions per unit of GDP over between 1990 and now?

Recent comments by Federal Minister for the Environment, Greg Hunt, implied that Australia is leading the world in reduction of greenhouse gas emissions per unit of GDP. Is that right?
The Great Barrier Reef is one of the most magnificent wonders of our world.
With the United Nations set to decide on whether to list the Great Barrier Reef as officially in danger, we look at the various threats to the reef's survival, starting with the biggie... climate change.
Hong Kong: a showcase for Asian urban development.
Nobel Laureates met recently in Hong Kong to sign a memorandum calling for cities to help guard against climate change. As the most creative places on the planet, big cities are the perfect place to meet this challenge.
Australia needs a better guardrail to stop emissions increasing.
While the recent emissions reduction auction in Australia was a success, much more needs to be done to build an effective climate policy.
Australian cattle wait to be loaded onto a ship to Indonesia. Their voyage to the United States would be even longer.

Australia's cattle industry is keen to begin live exports to the United States. But America is very different to existing live export markets such as Indonesia, making the move much more ethically fraught.
The Fukushima disaster was a dark chapter for nuclear power - but high-profile accidents are far from the only downside.
Is nuclear power worth it? No, says Mark Diesendorf – it's never been a major world energy force, it has caused huge accidents, and its greenhouse emissions are higher than many people realise.
Looking over Palmerston and the East Arm of Darwin Harbour to the new $35B Inpex LNG plant. Many resources projects in the north are in beautiful, environmentally important places.
This year's federal budget outlined plans for infrastructure in northern Australia, but it will need to do more than build roads and rail to sustainably develop the north.
Leadbeater’s possum needs more than a ‘set and forget’ approach to conserving the forests where it lives.

A large new national park might sound like the best way to protect the critically endangered Leadbeater's possum. But it won't do anything to save possums from the major threat of bushfire.
A nuclear-capable Pakistani missile during testing in 2011. The international community hopes other aspiring nuclear nations can develop nuclear power without the military muscle.
Through history, nuclear power has gone hand in hand with the nuclear arms race. But does it have to be this way? Closer international cooperation can help nations embrace nuclear power peacefully.
The Joint European Torus (seen here with a superimposed image of a plasma) is one of the machines helping to unlock fusion power.
Why don't we have nuclear fusion power yet? Because it involves taming plasmas at temperatures far hotter than the Sun's core. But the good news is that physicists are slowly but surely figuring out how.
Maurice Newman, AC, is chair of the Prime Minister’s Business Advisory Council.

Maurice Newman's implication that discrepancies resulting from the recent climate fluctuation somehow invalidates climate models is incorrect.
Australia has committed to a long-term global average temperature increase to no more than two degrees Celsius – yet often envisions a future in which its is a major coal exporter.
When it comes to climate change and Australia's economic future, different crystal balls can produce vastly different results.
Bjorn Lomborg’s cost-benefit approach isn’t necessarily the best way to look at problems with a global scope.
Simon Wedege/Wikimedia Commons
Bjorn Lomborg's "consensus" approach involves ranking global development policies by their ratio of benefit to cost. But this hard-headed economic rationale can actually end up entrenching inequality.
More mines, more roads, as the government puts its drive towards economic development ahead of all else.

Amid talk of paths to surplus and investing in infrastructure, both sides of politics seem to have forgotten Australia's longstanding responsibility to govern sustainably, and not just for the economy.
Whale sharks were one of the warm water species to move south during the 2010-2011 marine heatwave.
While eastern Australia trembles in the face of an El Niño, Western Australia's oceans could finally see relief from devastating marine heatwaves.
Breaking the ice: while scientists increasingly understand why Antarctic sea ice is growing, it remains tricky to forecast.
Australian Antarctic Division
Antarctica's sea ice is changing in ways that scientists didn't predict, and is now causing headaches for Antarctic stations.
Research shows monocultures of crops - such as this canola field - can be bad for the environment.
Monocultures - vast expanses of a single crop - may look pretty, but mounting research shows they are likely bad for environment. And in turn that's bad news for farms as well.
