18 May 2015, The Conversation: FactCheck: Are 95% of models linking human CO₂ emissions and global warming in error? In a recent newspaper column, Mr Newman said discrepancies between climate model forecasts and recorded temperatures begged the question: “Why then, with such little evidence, does the UN insist the world spend hundreds of billions of dollars a year on futile climate change policies?” All scientists would agree with Mr Newman that critical analysis of mathematical modelling is a crucial part of science. But it is a logical fallacy to leap from that valuable topic to describing climate change policies as futile. Climate models: what they can and can’t do. Read More here

8 May 2015, ClimateWire: New England city turns to its wastes to ensure year-round supply of fresh vegetables and fish. By this time next year, residents in Keene, N.H., will have year-round access to local and sustainable fish and vegetables, thanks to their municipal landfill. Keene’s city officials are partnering with an organization called the Local Farms Project with plans to construct a 1-acre greenhouse and a recirculating aquaculture system on the grounds of the closed Keene Landfill. Once it is fully operational, the Keene Energy and Agriculture Project is expected to produce 500,000 pounds of fresh lettuce and herbs and 66,000 pounds of live tilapia for local grocery wholesalers each year.

Q&A with Ross Garnaut: ‘we’re not there yet’ on climate policy. Following the repeal of the carbon tax, the Australian government has implemented its Direct Action climate policy, centred on the A$2.55 billion Emissions Reduction Fund. The results of the fund’s first auction were released on April 23. So far, the government has signed contracts for 47 million tonnes of carbon emissions for a total of A$660 million. However, questions remain about the long-term adequacy of the fund and its ability to achieve Australia’s unconditional emissions target of 5% below 2000 levels by 2020, and larger cuts beyond. The Conversation asked Ross Garnaut, Professorial Research Fellow in Economics at the University of Melbourne and architect of Australia’s carbon tax, what Australia needs to do to build an adequate climate policy. Garnaut was a keynote speaker at the recent Emissions Reduction Summit held in Melbourne. Read More here
6 May 2015, RTCC: Fossil fuels just pushed CO2 levels to a 3 million-year high: Global concentrations of greenhouse gases surpass “significant milestone”, US climate science agency says, the amount of carbon dioxide in the Earth’s atmosphere exceeded 400 parts per million in March, the National Oceanic and Atmospheric Administration reported today. That’s the most in 57 years of measurements, a near 50% rise on pre-industrial levels, and probably the highest since the Pliocene Epoch, 2.6-5.3 million years ago. Read More here
