18 May 2016, The Conversation, Are toxic algal blooms the new normal for Australia’s major rivers? For much of this year, up to 1,700 kilometres of the Murray River has been hit by a serious outbreak of potentially toxic blue-green algae, which has flourished in the hotter-than-average conditions. After three months, the river is now recovering with the arrival of wet weather. But we are unlikely to have seen the last of these poisonous microbes. Large blue-green algal blooms are a relatively new phenomenon in inland waterways. In 1991 an algal bloom affected more than 1,000 km of the Darling River, the first time such an event had been reported in an Australian river, and one of the few times internationally. It was an environmental disaster, killing livestock and striking a telling blow against Australia’s reputation as a clean, green farming nation. The response was decisive: a state of emergency was declared, and the bloom ultimately gave rise to significant investment by state and federal governments into freshwater research, particularly in the Murray-Darling Basin. Why no emergency now? Fast forward two and a half decades to the latest bloom afflicting the Murray River, one of Australia’s most socially, economically and culturally significant waterways. The past decade has seen four similar blooms on the Murray River: in 2007, 2009, 2010 and now. Yes, they have garnered press attention, but there has not been the same call to arms that we saw when the Darling River was struck in 1991. It is almost as if such significant environmental events are now simply seen as the new normal. Why the apparent complacency? The 2007, 2009 and 2010 algal blooms on the Murray River all happened during the Millennium Drought, and hence were probably ascribed to an aberration in the weather. In reality, the situation may have more to do with how we manage water in Australia – particularly during periods of scarcity, such as the one we may well be entering now. Read More here

6 May 2016, The Guardian, Greg Hunt: no definite link between coal from Adani mine and climate change. The federal environment minister has argued in court that coal from Australia’s largest coalmine would have no “substantial” impact on climate change and as a result he did not need to consider whether it would affect the Great Barrier Reef. The Australian Conservation Foundation challenged Greg Hunt’s approval ofAdani’s Carmichael mine, alleging he failed to consider the impacts the burning of the coal from the mine would have on climate change and hence on the Great Barrier Reef. Scientists have found the current mass bleaching event affecting 93% of the reefwas made 175 times more likely by climate change and would become a biennial event within 20 years. After that point, the continued existence of the reef would be in doubt. In federal court documents obtained by Guardian Australia, Hunt denied he failed to consider the impacts of coal on the reef. In the outline of submissions filed on behalf of the minister, the Australian government solicitor explains that the minister did not think the burning of the coal “would be a substantial cause of climate change effects” and would have “no impact on matters of national environmental significance”.

28 April 2016, RenewEconomy, Climate policy becomes trench warfare, once again. The release of Labor’s climate policy has led immediately to a resumption of World War I style trench warfare. The opening salvo, the pre-prepared advertisements and admonishments, was blasted off within hours, to be followed by tunnelling under the Labor trenches, minefields and more misery for both major Parties and for the population they are elected to serve. The misery is the suffering from current and future ill health which could be prevented if progress could be made in a bilateral, constructive manner. Labor’s policy has significant health implications because health is closely linked to energy policy and it is in this light that Doctors for the Environment Australia (DEA) makes comment. Our profession is reminded that WHO regards climate change as the biggest health threat of the present century. Our involvement is therefore a vital professional commitment to the health care of communities and patients. Good energy policy has the ability to provide the co-benefits of reduced air pollution which contributes to death and illness from heart and lung disease in thousands of Australians while at the same time reducing green house emissions which result in climate change and thousands of deaths world wide and many in Australia from increasing storm, flood and fire.

26 April 2016, RenewEconomy, Turnbull’s evolving climate strategy: When less is more. The Coalition government under Malcolm Turnbull has a rapidly evolving strategy on climate change and clean energy – announce new jobs and investments, but only after cutting even more jobs and investments. Those were the allegations levelled at the Turnbull government on Tuesday after the CSIRO announced a new climate change research centre in what appears to be a patch-up job by innovation minister Christopher Pyne and environment minister Greg Hunt, and Hunt’s announcement of an “extra” $50 million for the Great Barrier Reef. The CSIRO cuts are particularly galling for the science community. A new division to be based in Hobart, combining with elements of the Bureau of Meteorology, will employ 40 climate scientists. But CSIRO chief Larry Marshall, intent on converting the CSIRO from focusing on the public good to revenue opportunities with business, says 75 jobs will still be lost from the climate division, albeit down from 110. CSIRO climate scientists dismiss this as a “con” job. Professor Dave Griggs, a former director of Monash Sustainability Institute at Monash University said it was like “trying to put a sticking plaster over a gaping wound.” Similarly, Hunt on Tuesday announced $50 million of “new” funding for the Great Barrier Reef, which the government has finally realised is under grave threat following the worst bleaching event on record, which has touched more than 90 per cent of the reef. The Greens said: Not so fast, arguing that the funds simply replace monies cut in the past two years – $40 million from the Reef Water Quality Program in 2014, and $10 million from the Great Barrier Reef Marine Park Authority and the Australian Institute of Marine Science.
