We price carbon. This is nothing new. The first time this explicitly happened, Vanilla Ice hit number one in Australia, and Bryan Adams was topping the global charts with “(Everything I do) I do it for…
This is carbon. The carbon you keep hearing about on the news is probably carbon dioxide. It doesn’t look like this.
Rui Costa

Yesterday, Nick Rowley looked at the history of sustainability agreements and why we’ve reached the impasse of Rio+20. Today he suggests a different approach. Back in November 2005, your perspective on…
Vulnerable people and places are worst affected by weather-related disasters, especially those most reliant on the land.

Mental health problems cause profound suffering and are worthy of attention for that reason alone. But despite policy and service reform, such problems remain as common, expensive and disabling as they…
Plentiful carbon-based fuel and falling world energy prices are a mixed blessing.
Adrian Bradshaw/AAP
Since the middle of the last decade, well before the worldwide run-up in fuel prices during 2008, it has been widely believed that we are entering a new era of scarcity in carbon-based fuels such as oil…
A new field study has revealed that the effect of wave activity on oceans should be incorporated in long-term climate and…
Elinor Ostrom, the only woman to have won a Nobel prize for economics, was most famous for challenging the idea of the “tragedy of the commons”: that in the absence of government intervention, people will overuse shared resources.

The fifth edition of the Global Environmental Outlook (GEO-5) - a global environmental report card by the United Nations Environment Programme (UNEP) - reads like the results for a sedentary, middle-aged…
Farmers are adept at using science to deal with all kinds of challenges, but they have their doubts about climate change.
Jeff Pang
Farmers are some of the most innovative Australians - since 1970 they have lost 7.5% of arable land, but they’ve found ways to increase production by 220%. They’re also some of the most conservative, expressed…
Darkness visible: we’re driving animals to extinction, burning through resources, and throwing out natural balances, yet consumption still reigns.

State of the Future 2012, a quick introduction What is the “state of the future”? How successfully are we tackling global challenges threatening our collective future? These questions are asked annually…
The recent climate-related deaths of tracts of Western Australian forest go beyond a green issue.
George Matusick
Recent, unprecedented, climate-driven forest collapses in Western Australia show us that ecosystem change can be sudden, dramatic and catastrophic. These collapses are a clear signal that we must develop…

Elephants in the room, part two For all our schemes and mantras about making our lives environmentally “sustainable”, humanity’s assault on the planet not only continues but expands. What are the deep…
The numbers are just in. At a time when we need to be urgently reducing our CO₂ emissions, we are now emitting more than at any time in human history. However, it’s not too late to turn things around…
It’s not just greenhouse gases that affect climate: other air pollution could be changing atmospheric circulation.

The Earth’s principal climatic zones appear to be shifting poleward. If this continues, as climate models project, the weather patterns that give rise to deserts in the subtropics, and stormy wet weather…
