|Extensive melt over the Greenland Ice Sheet. This figure shows the daily, cumulative area of the Greenland ice sheet showing surface melt for 2012, 2011, 2010 and for the 1980 to 1999 mean. While melt was unusually extensive through May and June of 2012, the melt area increased rapidly in early July in response to an unusually warm weather event.

Mine-Field: The Dark Side of Australia's Resources Rush
Paul Cleary, Black Inc., 2012
Whether it be coal-seam gas, LNG or coal mega-mines, a resources rush is happening in just about every productive corner of our country. Yet at the same time oversight and regulation have been hollowed out.
Disturbing Signal That Bad U.S. Climate Stance Is About to Get Worse
Kelly Rigg, Huffington Post, 7 August 2012
Todd Stern, the U.S. Special Envoy for Climate Change, was in my neck of the woods the other day.

It’s official: Australia needs no new coal or gas baseload
Giles Parkinson, ReNewEconomy, 9 August 2012
Since pretty much the start of the National Electricity Market more than a decade ago, the Australian power industry has regarded the annual Electricity Statement of Opportunities as their bible to help pinpoint where a new coal or gas-fired generator might be needed to meet rising demand.

Stockpiles of the biggest crops will decline for a third year as drought parches fields across three continents, raising food-import costs already forecast by the United Nations to reach a near-record $USUS1.24 trillion.
Explaining Extreme Events of 2011 from a Climate Perspective
Attribution of extreme events shortly after their occurrence stretches the current state-of-theart of climate change assessment. To help foster the growth of this science, this article illustrates some approaches to answering questions about the role of human factors, and the relative role of different natural factors, for six specific extreme weather or climate events of 2011.
Advocates see recent extreme weather as a 'teachable moment'

Climate change is already here
Michael E. Mann, ABC Environment, 8 Aug 2012
The first scientist to alert Americans to the prospect that human-caused climate change and global warming was already upon us was NASA climatologist James Hansen. In a sweltering US Senate hall during the hot, dry summer of 1988, Hansen announced "it is time to stop waffling... The evidence is pretty strong that the [human-amplified] greenhouse effect is here."

Carbon price claims SA’s largest coal-fired generator
Giles Parkinson, ReNewEconomy, 2 August 2012
The first coal-fired generator to shut down since the introduction of the carbon price has done so quietly, with the 544MW Northern power station near Port Augusta in South Australia closing down little more than a week after the introduction on July 1. The shut-down actually occurred a week later than planned because of relatively high wholesale electricity prices
Two reasons why Victoria will never be a brown coal export hub
Rod Campbell, ReNewEconomy, 8 August 2012
Last Friday, the Victorian and federal governments announced a $90 million fund to develop brown coal processing technology in the Latrobe Valley. The fund is called the Advanced Lignite Demonstration Program (ALDP) and, according to the brochure, its main goal is the “development of low-emission coal products for export”.
The inevitability of solar PV in Australia
Nigel Morris, ReNewEconomy, 8 August 2012
Over the last few months, I have had the pleasure of presenting to hundreds of solar industry delegates at the EcoGeneration Master Classes held around Australia. Inevitably, the most interesting part for me was the conversations with so many who are at the ‘coal face’; working day in, day out to sell the virtues of solar photovoltaic (PV) against rising coal-fired energy prices.
Bolt from the blue: How Australia got gold in rooftop solar
Giles Parkinson, ReNewEconomy, 6 August 2012
Australia has long been regarded as one of the pioneers of the global solar photovoltaic industry, courtesy of its excellent research at institutions such as UNSW and elsewhere. Now, thanks to its excellent solar resource, rising electricity costs and the falling cost of solar PV, it is now emerging as the leading market for rooftop solar as well.
James Price Point: An economic analysis of the Browse LNG project
According to the Western Australian government’s own economic assessment, the Browse LNG precinct proposed for James Price Point is likely to have a significant adverse impact on the state’s budget, will employ few local workers and harm the region’s reputation as a tourist destination, a new analysis by The Australia Institute has found.
