5 June 2017, Renew Economy, Finkel’s fine line through Australia’s testy power politics. It now seems certain that chief scientist Dr Alan Finkel will deliver a range of options for government policy makers when presenting his review to the COAG ministers and leaders this Friday. There will be mention of the emissions intensity scheme, but because a carbon price of any form is not on the menu of this Coalition government, other more “palatable” alternatives will be on offer, including a low emissions target, an option on pairing new renewables with storage or back-up and, possibly, a pathway for regulation. All have their merits. But as in any policy, the devil will be in the detail and the way these schemes are designed – for the future or the past. And it is going to be interesting to see how Finkel presents his case. Will it be his view of what should be done? Or will it be focused on what can be managed in the current political environment? Certainly, there is a growing chorus among politicians and the mainstream media that something should be done. But there is not a lot of thought into what these policies can actually achieve, even though they should obviously seek to meet climate targets and manage the energy transition efficiently and at lowest cost. The problem was that none of the institutions could bring themselves to actually say it: that wind and solar are by far cheaper than coal and gas and any “other low-carbon technologies”. The Australian Energy Markets Commission and the Climate Change Authority reinforced their support for an emissions intensity scheme (EIS), and only saw a low emissions target (LET) as a second-best measure. Once again, those recommendations simply reinforce preconceived ideas, and lousy modelling. Both institutions came out strongly in support of an EIS last year, but as we pointed out at the time, here and here, these positions were based on hopelessly pessimistic modelling inputs on the cost of solar and wind.

5 June 2017, Renew Economy, “Reputation” clause may scupper government loan deal for Adani. The federal government’s ability to hand Adani Energy a $1 billion loan to help finance the rail link for the Carmichael coal project in the Galilee basin has been dealt a decisive blow by the emergence of a “reputation” clause that must guide the board of Northern Australia Infrastructure Facility (NAIF). The Board of NAIF is expected to make a decision on whether to grant the funding in the next few days, but legal experts, financiers and environmental advocates argue that the existence of the reputation clause written in to the investment mandate by then resources minister Josh Frydenberg make it impossible for approval to be given. Leading environmentalists and climate change advocates such as Tim Flannery and John Hewson says the wording of the “reputation” clause should forbid the directors from supporting the loan, particularly in light of the international climate deal, the impacts on the Greater Barrier Reef, and on water quality. They say that Section 16 of the Investment Mandate of the NAIF, a $5 billion fund created by the Coalition government that is yet to make a single investment, is quite clear and specific: Read More here
1 June 2017, The Conversation, Global stocktake shows the 43 greenhouse gases driving global warming. The most comprehensive collection of atmospheric greenhouse gas measurements, published today, confirms the relentless rise in some of the most important greenhouse gases. The data show that today’s aggregate warming effect of carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) is higher than at any time over the past 800,000 years, according to ice core records. Building on half a century of atmospheric measurements by the international research community, we compiled and analysed the data as part of a group of international scientists, led by Malte Meinshausen from the University of Melbourne in collaboration with CSIRO. Together, the data provide the most compelling evidence of the unprecedented perturbation of Earth’s atmosphere. They clearly show that the growth of greenhouse gases began with the onset of the industrial era around 1750, took a sharp turn upwards in the 1950s, and still continues today. Research has demonstrated that this observed growth in greenhouse gases is caused by human activities, leading to warming of the climate – and in fact more than the observed warming, because part of the effect is currently masked by atmospheric pollution (aerosols). The new collection of records comes from measurements of current and archived air samples, air trapped in bubbles in ice cores, and firn (compacted snow). The data cover the past 2,000 years without gaps, and are the result of a compilation of measurements analysed by dozens of laboratories around the world, including CSIRO, the Bureau of Meteorology’s Cape Grim Station, NOAA, AGAGE and the Scripps Institution of Oceanography, among others.

29 May 2017, Independent, Great Barrier Reef can no longer be saved, Australian experts concede. The Great Barrier Reef – a canary in the coal mine for global warming – can no longer be saved in its present form partly because of the “extraordinary rapidity” of climate change, experts have conceded. Instead, action should be taken to maintain the World Heritage Site‘s ‘ecological function’ as its ecological health declines, they reportedly recommended. Like coral across the world, the reef has been severely damaged by the warming of the oceans with up to 95 per cent of areas surveyed in 2016 found to have been bleached. Bleaching is not always fatal but a study last year found the “largest die-off of corals ever recorded” with about 67 per cent of shallow water coral found dead in a survey of a 700km stretch. Now experts on a committee set up by the Australian government to improve the health of the reef have revealed that they believe the lesser target of maintaining its “ecological function” is more realistic. In a recent communique, the expert panel said they were “united in their concern about the seriousness of the impacts facing the Reef and concluded that coral bleaching since early 2016 has changed the Reef fundamentally”. “There is great concern about the future of the Reef, and the communities and businesses that depend on it, but hope still remains for maintaining ecological function over the coming decades,” it said. “Members agreed that, in our lifetime and on our watch, substantial areas of the Great Barrier Reef and the surrounding ecosystems are experiencing major long-term damage which may be irreversible unless action is taken now.
