The global grassroots movement against dirty, polluting coal-fired power has added another continent to the ranks of those finally moving away from the carbon-intensive fuel source: Australia.
The Heat of the Moment
George Monbiot, Guardian, 28 August 2012
There are no comparisons to be made. This is not like war or plague or a stockmarket crash. We are ill-equipped, historically and psychologically, to understand it, which is one of the reasons why so many refuse to accept that it is happening.
Russia Plays Game of Arctic Roulette in Oil Exploration
Benjamin Bidder, Matthias Schepp and Gerald Traufetter, Spiegel, 24 August 2012
Thawing sea ice and improved technology is opening up the race for natural resource exploration in the Arctic Circle, home to nearly a quarter of the world's untapped oil reserves. Russia leads the race and has promised to adhere to environmental guidelines. But accidents and other damage resulting from the country's oil exploration tell a different story.
Carbon price shock: more likely to go up than down
Giles Parkinson, ReNewEconomy, 30 August 2012
The overwhelming reaction to news that Australia is to ditch its carbon floor price – in response to a push by business and as a condition to linking with the European Emissions Trading Scheme – has been one of relief. Surely, the argument goes, the carbon price must go down.
We Are Writing the Epilogue to the World We Knew
John Atcheson, Common Dreams, August 31, 2012
The data continue to roll in, and they are telling us we are in the process of bringing an end to the world we evolved in, and creating a new, harsher world. We will be forced to devote more and more of our resources trying to adapt to this new world, and less on development.

What Sea-Ice Melt Means For Our Climate Policy
David Spratt, New Matilda, 28 August 2012
There's half as much sea-ice as there was 30 years ago and the annual summer melt keeps smashing records. Here's why Australian policy-makers should be paying attention.
Why Arctic sea ice shouldn't leave anyone cold
Neven, Arctic Sea Ice blog, 26 August 2012
The sea ice is leaving us a bit more every year. It's time to start contemplating its absence, which is why I teamed up with Kevin McKinney to write an extended version of the shorter piece you might see pop up here and there.
Satellites Show Sea Ice in Arctic Is at a Record Low
Justn Gillis, NYT, 27 August 2012
The amount of sea ice in the Arctic has fallen to the lowest level on record, a confirmation of the drastic warming in the region and a likely harbinger of larger changes to come.

Arctic Tipping Point: A North Pole Without Ice
Fen Montaigne, environment360, 30 August 2012
Scientists say this year’s record declines in Arctic sea ice extent and volume are powerful evidence that the giant cap of ice at the top of the planet is on a trajectory to largely disappear in summer within a decade or two, with profound global consequences.
Carbon release from collapsing coastal permafrost in Arctic Siberia
Phys.org, August 30, 2012
In this week's issue of Nature a study lead by Stockholm University, with collaborators from Russia, US, UK, Switzerland, Norway, Spain and Denmark, show that an ancient and large carbon pool held in a less-studied form of permafrost ("Yedoma") is thaw-released along the ~ 7000 kilometer desolate coast of northernmost Siberian Arctic.

POLITICS AND POLICY
Owning Adaptation in the Pacific: Strengthening governance of climate adaptation finance
Pacific Island peoples are already feeling the effects of climate change. Living in one of the world’s most vulnerable regions to climate impacts, Pacific communities face no option but to adapt if they are to build a resilient future. But adaptation poses different challenges from aid programmes and the delivery of public services.

Carbon markets – you’ll never walk alone…
Freddy Sharpe, ReNew Economy, 29 August 2012
The changes to the design of the Australian carbon price represent smart politics. They also look to be good environmental and economic policy. They will underpin support in the medium term for CFI projects and they will make it harder for anyone who wants to repeal the whole Clean Energy Futures legislative package. (Blood oath, they will.)
PM's concession on carbon
David Woe, The Age, 29 August 2012
The Gillard government has made a concession to big business and tweaked its carbon price, potentially creating a budget black hole and endangering incentives for the switch to cleaner energy.

Severe summer drought recalls damaging Dust Bowl days
Kevin G. Hall, McClatchy, August 26, 2012
Farmers in this hardscrabble patch of the Midwest know the discomfort of summer heat, they've suffered through dry weather before, and they've certainly lived through the boom and bust cycles of modern farming. But they've never season a drought like the one that's gripping much of the nation, and they're seeing miserable growing conditions rivaled only perhaps by the Dust Bowl days of the 1930s.
Emissions accounting: China's uncertain CO2 emissions
Gregg Marland, Nature Climate Change, 28 August 2012
Climate change mitigation commitments and basic carbon-cycle science both require reliable information on carbon dioxide emissions. Uncertainties in energy data and carbon dioxide emissions estimates are particularly important when they involve large emitters.
