California is aiming for its emissions to be at 1990 levels by 2020 and to be 40% below 1990 levels by 2040 below 1990 levels. The state of California has a population of 38 million and an economy about 30% larger than Australia’s. Continue reading California sets pace with 40% emissions reduction target
Climate change challenges to health
Australians will have to adapt to reduce the risk of health impacts from climate change, according to a report released today by the Australian Academy of Science. Continue reading Adapt now to prevent poor health from climate change

The sun will help treat waste water at Jamestown in South Australia, and brighten job prospects, with the launch of Australia’s first floating solar energy generation plant. The installation is the first of a $12 million, 4 megawatt system … It floats on sewerage water … Continue reading Solar panels powering sewerage
Australia needs to cut its CO2 emissions by 236 million tonnes to meet its official target, agreed under the Kyoto Protocol, of cutting emissions by 5% below 2000 levels by 2020.
The first emissions auction bought 47.3 million tonnes of carbon emissions for about $660 million, an average of about $14 per tonne of CO2.
The Emissions Reduction Fund budget is $2,550 million. If the cost of carbon emissions remains at $14 per tonne, then The ERF will only be able to buy 182 million tonnes – which is short of the target 236 million, short by 54 million tonne or 23%.
The article details why this 23% shortfall, or even a 30% shortfall, is optimistic. This is a shortfall against our meager 5% cut in emissions!

Rapid Arctic warming
The Arctic has warmed about twice as fast as the rest of the Northern Hemisphere in recent decades. Summer Arctic sea ice has declined by 40%, and snow is melting earlier in spring on the surrounding land. This dramatic change in the climate system is expected to affect weather patterns well beyond the confines of the Arctic
Scientists agree that an increase in atmospheric greenhouse gases causes the Earth’s temperature to rise, but they’ve also noticed that … warmer temperatures also seem to correspond with an increase in greenhouse gases. But drawing conclusions about the nature of the relationship is tricky, because though scientists have seen a correlation, they haven’t been able to show causation. Now, scientists believe they’ve untangled the relationship. In a paper published Monday in Nature Climate Change, researchers from the University of Exeter claim to have found direct evidence that as global temperatures rise, so does the atmospheric concentration of greenhouse gases, creating a positive feedback that in turn warms the Earth even more — basically, global warming creates more global warming.
