5 July 2017, The Guardian, Climate Change Authority loses last climate scientist. Imagine, if you will, a government board to champion Australian arts without any artists on it, or an agency to advise on medical research without any medical researchers. Or perhaps even, imagine a government authority set up to provide expertise on climate policy without any actual climate scientists. Well you don’t have to imagine that last one, because that’s what we now have – the government’s Climate Change Authority is now sans climate scientist. Prof David Karoly, of the University of Melbourne, has just finished his term on the authority’s board – the only member to stick it out for the full five years. Karoly says without someone to replace him, the authority will struggle to fulfil its legal mandate. He told me: I think that it is critically important that at least one member of the Climate Change Authority is an expert and experienced climate change scientist. Such a member is needed to provide information and interpretation on the latest climate change science publications and data. In my view, it can only do that with a climate change scientist as a member, to provide expert assessment of the effectiveness of proposed greenhouse gas emission reductions nationally and globally, and the projected impacts on Australia from current and future climate change. The Climate Change Authority Act 2011 states that, in conducting a review, the authority must have regard to environmental effectiveness among a number of other matters. I asked the Department of the Environment and Energy if there were any plans to replace Karoly with another climate scientist. The department said: Government appointments to the CCA are a matter for the Government under the CCA’s legislation. The Chief Scientist is an ex officio Member of the Authority and can assist on scientific matters and in providing access to the scientific community, including climate scientists. So in other words, it won’t replace Karoly and will instead just rely on the chief scientist, Alan Finkel, to act as a go-between, which of course is much more efficient and logical than actually having a climate scientist right there in the room. That would be silly, right? Read More here

30 June 2017, Renew Economy, Another blow to CCS, as EU power giants bow out of Dutch project. European power giants Engie and Uniper have withdrawn from a test project to capture and store carbon dioxide generated by one of several major new coal plants in the Netherlands, dealing yet another blow to the prospects of “clean coal” technology, in which the Australian government and fossil fuel lobbyists still hold much stock. Reuters reported this week that the two companies – one of which, Engie, the majority owner of Australia’s Loy Yang B brown coal-fired power station in Victoria’s Latrobe Valley, and who recently closed Hazelwood, – had told the Dutch government they no longer intended to participate in the CCS project, the biggest of its kind in Europe. Holland’s economic affairs Minister Henk Kamp said in a statement he would “examine whether legal steps can be taken to recoup” unspecified subsidies paid to the companies if they had not changed their minds by mid-September. The minister also said that the companies’ withdrawal from the project “changed nothing” in the government’s resolve to develop large-scale CCS demonstration projects. Read More here
28 June 2017, Climate Home, Even Boeing-747 tanker jets can’t win our total war on fires. The more effectively we suppress fires, the worse they become. As climate change makes the world more combustible, we need a new approach. In 1910 Ed Pulaski, a US Forest Service ranger, rounded up his men who were fighting a forest fire in dense conifer forests in northern Idaho and forced them, some at gunpoint, to take refuge in an abandoned mine shaft. The Pulaski tunnel (now a tourist site) represents the dramatic historical moment when ad-hoc approaches to controlling wildfire were shown to be utterly inadequate – this heroic failure provided the impetuous for the US Forest Service to declare total war on fire. Nearly all of Pulaski’s men survived the conflagration, one of thousands of fires that burnt across Idaho during an extremely hot and dry summer, an event now known at the ‘Big Burn’. The sheer ferocity, geographic scale and destructive power of the 1910 Idaho fires shifted the focus of the US Forest Service (USFS) from forestry toward fire fighting. This led to the development of networks of fire towers to identify wildland ignitions. They would be extinguished by teams of trained forest fire fighters, many of whom use a combined ax and mattock invented by, and named after, Ed Pulaski.The iconic mascot Smokey Bear was created by the US advertising industry to promote forest fire awareness. The USFS fire fighting policy evolved to a mandated extinguishment of any new forest fire ignition by 10am the following day, with some managers demanding that the fire size was kept below 10 acres. This total war on fire also drove innovation. In the early 1960 the USFS established Fire Lab at Missoula where an aeronautic engineer, redeployed after the defence department project he was working on was cancelled, developed the first mathematical description of fire, creating the foundation for predictive fire behaviour modelling….But there is a very big catch. The US approach is proving to be ecologically and economically unsustainable – especially in an era of increasing fire threat due to climate change.1 Total fire suppression has created the ‘fire suppression paradox’: the more effective suppression is the worse fires become. Fuel that would historically have been burnt by lightning or indigenous people builds up, resulting in catastrophic fires that are uncontainable regardless of the available technology. The fire suppression paradox also has another unintended and counterproductive consequences: communities come to believe flammable landscapes are safe, resulting in increasing urban sprawl into wildlands that are primed to burn. This massively increases the risk of loss of life and property and the inevitable, tragic loss drives further investment into aerial fire fighting. Climate change is turbo-charging this feedback – fire seasons are worsening, fire disasters are becoming more destructive, and hence demands for more investment in aggressive fire fighting are growing worldwide. Collectively this is creating a dangerous and economically and ecologically unsustainable fire-suppression spiral. Read More here
28 June 2017, The Conversation, The world’s tropical zone is expanding, and Australia should be worried. The Tropics are defined as the area of Earth where the Sun is directly overhead at least once a year — the zone between the Tropics of Cancer and Capricorn. However, tropical climates occur within a larger area about 30 degrees either side of the Equator. Earth’s dry subtropical zones lie adjacent to this broad region. It is here that we find the great warm deserts of the world.Earth’s bulging waistline Earth’s tropical atmosphere is growing in all directions, leading one commentator to cleverly call this Earth’s “bulging waistline”. Since 1979, the planet’s waistline been expanding poleward by 56km to 111km per decade in both hemispheres. Future climate projections suggest this expansion is likely to continue, driven largely by human activities – most notably emissions of greenhouse gases and black carbon, as well as warming in the lower atmosphere and the oceans. If the current rate continues, by 2100 the edge of the new dry subtropical zone would extend from roughly Sydney to Perth. As these dry subtropical zones shift, droughts will worsen and overall less rain will fall in most warm temperate regions. Poleward shifts in the average tracks of tropical and extratropical cyclones are already happening. This is likely to continue as the tropics expand further. As extratropical cyclones move, they shift rain away from temperate regions that historically rely upon winter rainfalls for their agriculture and water security. Researchers have observed that, as climate zones change, animals and plants migrate to keep up. But as biodiversity and ecosystem services are threatened, species that can’t adjust to rapidly changing conditions face extinction. In some biodiversity hotspots – such as the far southwest of Australia – there are no suitable land areas (only oceans) for ecosystems and species to move into to keep pace with warming and drying trends. We are already witnessing an expansion of pests and diseases into regions that were previously climatically unsuitable. This suggests that they will attempt to follow any future poleward shifts in climate zones. Read More here
