ACT government seeks 90% renewables by 2020
Giles Parkinson, Renew Economy, 19 September 2012
The ACT government has outlined an ambitious plan to source 90 per cent of its energy requirements from renewable energy by 2020, with solar, wind and energy efficiency at the centrepiece of its strategy.

Four-degree rise demands 90-degree rethink
Ian Dunlop, SMH, September 22, 2012
Climate change has moved into a new and dangerous phase. The Arctic has been warming two to three times faster than the rest of the world. In the past few weeks, melting of the Arctic sea ice has accelerated dramatically, reducing the area and volume to levels never previously experienced.

Yikes: Avoiding dangerous climate change is still possible, but just barely
David Roberts, Grist, 17 September 2012
The most extreme climate “alarmists” in U.S. politics are not nearly alarmed enough. The chances of avoiding catastrophic global temperature rise are not nil, exactly, but they are slim-to-nil, according to a new analysis prepared for the U.K. government.

Entire environments to 'disappear': CSIRO
Julian Drape, The Age, 18 September 2012
Conserving Australia's environment as it is today will become increasingly impossible as the world warms, so governments should instead focus on managing environments as they change, the CSIRO says.
Climate change will transform the bush … and we’ll have to think big to cope
David Hilbert, The Conversation, 18 September 2012
Within decades, environments across Australia will be substantially different from those that currently exist.

Tipping into new climate territory as scientists put fears on ice
Ben Cubby, The Age, September 23, 2012
As Arctic sea ice hits a record low, focus is turning to climate ''tipping points'' - a threshold that, once crossed, cannot be reversed and will create fundamental changes to other areas.

Earth's attic is on fire
Jeff Masters, Wunderblog, September 20, 2012           
The extraordinary decline in Arctic sea ice during 2012 is finally over. Sea ice extent bottomed out on September 16, announced scientists at the National Snow and Ice Data Center (NSIDC) on Wednesday.

Shipping, oil hunt may accelerate Arctic thaw
SMH, September 19, 2012
Local pollution in the Arctic from shipping and oil and gas industries, which have expanded in the region due to a thawing of sea ice caused by global warming, could further accelerate that thaw, experts say.

Opening the fabled Northwest Passage: triumph or tragedy?
Peter Doherty, The Conversation, 18 September 2012
A combination of 33-year satellite records, measurements made over the past century, and long-term proxy analysis suggests Arctic sea ice may be at its lowest level for more than 1,000 years.

Greenland’s ‘Ice Quakes’ May Set a Record
Justin Gillis, NYT blog, 21 September 2012
One of the more amazing facts about the ongoing destruction of the Greenland ice sheet is that it is producing earthquakes that can be detected worldwide.


Report: Alarming new findings for our climate & our Reef
This week, the Arctic ice sheet melted to its lowest extent in human records – the result of an increasingly warming climate. Australia’s biggest contribution to global warming is our coal exports. While the Arctic ice reaches historic lows, Australia’s coal exports are reaching historic highs. Today Greenpeace reveals the true cost of Australia’s coal boom.

The farmer wants a life: minister urges lockout over coal seam gas
Sean Nicholls, Sydney Morning Herald, September 18, 2012
The Minister for Western NSW, Kevin Humphries, has encouraged a group of farmers to continue to ''lock the gate'' to prevent coal seam gas companies entering their land just days after a cabinet decision on new rules to balance the interests of miners and farmers.

Brown coal generators: Let’s stop renewables now
Giles Parkinson, reNewEconomy, 20 September 2012
International Power, the owner of the Hazelwood brown coal generator in Victoria, has joined the owners of the Yallourn brown coal facility in calling for an effective halt to the deployment of wind and solar energy to protect their profits.

Water-based battery a step up for renewable energy
Manickam Minakshi-Sundaram & Danielle Meyrick, The Conversation, 19 September 2012
Energy storage will be critically important as we work towards sustainable living. Developing cost-effective ways to store large amounts of electricity from wind turbines and solar farms will be essential in turning from fossil fuels to renewables as our primary source of energy.

Deepening Doubts About Fracked Shale Gas Wells' Long Term Prospects
This month, the Pennsylvania Department of Environmental Protection released its bi-annual report on how much natural gas has been produced in the Marcellus Shale, a rock formation which stretches underneath much of Appalachia.

Department issues coal seam gas emissions warning
Ben Cubby, SMH, September 21, 2012
No one knows precisely how much methane leaks from Australia's growing coal seam gas
fields, and more research is needed to back up industry claims about greenhouse emissions, a report produced for the federal government has found.

The curious blindness of climate deniers
Dan Turner, LA Times, September 18, 2012
Climate change has seldom warranted a mention during the 2012 congressional campaigns, a sign both of the nation's changing priorities as it copes with an economic downturn and the extent to which conservative politicians and the fossil fuel industry have succeeded in sowing doubts about the scientific consensus.
