19 August 2015, Renew Economy, The six big lies in Tony Abbott’s attack on the environment. The Abbott government has revealed plans to repeal a section of Australia’s environment laws that allows green groups to challenge approvals for mining projects and other large developments in the courts. Federal Attorney-General George Brandis said the government would seek to repeal section 487 (2) of the Environment Protection and Biodiversity Conservation Act and “return to the common law”, after it was used successfully by the Mackay Conservation Group to overturn the federal environment minister’s approval of the Carmichael mega-coal mine in Queensland’s Galilee Basin. The following is a run-down of the six big lies at the centre of the Coalition’s latest attack on the environment…Read More here

18 August 2015, The Guardian, Abbott government war on green ‘saboteurs’ is Laurel and Hardy slapstick. The Coalition’s ‘war on environmental vigilantes and saboteurs’ isn’t consistent: it’s waged against anti-coal activists but in support of anti-windfarm activists. Even for the Abbott government the inconsistencies in the latest “war on environmental vigilantes and saboteurs” are astonishing. And the slapstick nature of its attempt to use the issue as a political wedge is up there with Laurel and Hardy. When an environment group successfully uses 16 year-old national environmental laws to delay a project, the Abbott government tries to change the law to prevent them from ever doing it again. But if an anti-windfarm group can’t find a way to use existing laws and regulations to stop or delay a project, the Abbott government tries to change laws and processes to make it easier for them to succeed. The first is called green “vigilantism” and “sabotage” and the second is, according to environment minister Greg Hunt, a reasonable response because “many people have a sense of deep anxiety, and they have a right to complain.” The government calls regulations that stop fossil fuel or mining projects “green tape”, but a wind commissioner and yet another scientific committee to look at unsubstantiated health complaints regarding wind turbines is apparently no kind of “tape” at all.

18 August 2015, The Conversation, The government vs the environment: lawfare in Australia. A key feature of authoritarianism is that the government is above the law – it is not accountable to the people for its actions. In contrast, under a democratic system, the rule of law means that the government is constrained by law and can be held accountable by the people. This is particularly pertinent to the move by Attorney-General George Brandis to restrict green groups from challenging major developments under federal law, a direct response from this month’s successful appealagainst the approval of the controversial Carmichael coal mine, being developed by the Adani Group, on environmental grounds.Brandis plans to repeal section 487(2) of the Environmental Protection and Biodiversity Act and “return (it) to the common law”. His actions follow comments by Prime Minister Tony Abbott and Trade Minister Andrew Robb. Read More here
18 August 2015, Atmospheric Chemistry and Physics, Abstract. The injection of sulfur dioxide (SO2) into the stratosphere to form an artificial stratospheric aerosol layer is discussed as an option for solar radiation management. The related reduction of radiative forcing depends upon the injected amount of sulfur dioxide, but aerosol model studies indicate a decrease in forcing efficiency with increasing injection rate. None of these studies, however, consider injection rates greater than 20 Tg(S) yr−1. But this would be necessary to counteract the strong anthropogenic forcing expected if “business as usual” emission conditions continue throughout this century. To understand the effects of the injection of larger amounts of SO2, we have calculated the effects of SO2 injections up to 100 Tg(S) yr−1. We estimate the reliability of our results through consideration of various injection strategies and from comparison with results obtained from other models. Our calculations show that the efficiency of such a geoengineering method, expressed as the ratio between sulfate aerosol forcing and injection rate, decays exponentially. This result implies that the sulfate solar radiation management strategy required to keep temperatures constant at that anticipated for 2020, while maintaining business as usual conditions, would require atmospheric injections of approximately 45 Tg(S) yr−1 (±15 % or 7 Tg(S) yr−1) at a height corresponding to 60 hPa. This emission is equivalent to 5 to 7 times the Mt. Pinatubo eruption each year. Read More here
