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.

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.

28 May 2017, Climate News Network, Antarctica heights settle polar warming puzzle. Computer simulation shows that Antarctica is warming far slower than the Arctic region because of its much greater height. Scientists believe they have settled one of the great polar puzzles − why Antarctica is warming at a rate so much slower than the Arctic region. And the answer is a simple one: Antarctica is so much higher. To ram the point home, they used a computer simulation to hammer the entire southern continent until it was no more than a metre above sea level. At which point, in their simulation, warming at the South Pole became much more dramatic. The two poles are very different: the Arctic is an ocean almost entirely surrounded by land, while Antarctica is a vast continent entirely surrounded by frozen ocean. Landmass of ice As the north polar ocean ice melts, dark seas begin to absorb more radiation. In the southern hemisphere, the landmass of ice reflects radiation back into space to insulate the continent and keep its temperatures far below freezing. But the new study published in Earth System Dynamics journal shows that what makes the biggest difference is the elevation of the surface. Antarctica is not just an enormous continent: thanks to many millions of years of snowfall at very low temperatures, it is banked high with ancient ice. Its average elevation is 2,500 metres − far higher than the highest peaks in the UK, for example − and its highest mountain, Mount Vinson, reaches 4,892 metres, which is higher than any alpine peak in Europe. Evidence from the distant past and climate models both show that, in a warming world, the poles should warm faster than the rest of the planet. But while the Arctic is warming at twice the rate of the rest of the globe, change in Antarctica has been much more sluggish. Read More here
24 May 2017, DeSmogUK, Op-Ed: Glacial Progress at Bonn Climate Talks Shows Why we Need to Exclude Big Polluters From Negotiations. When it comes to the fossil fuel industry participating in UN climate negotiations, it’s clear there is a conflict of interest – and demands for this to end are nothing new. But after fierce resistance to this idea during talks in Bonn last week from the EU, US and Australia, more needs to be done, argues Pascoe Sabido of Corporate Europe Observatory. With just six months to go before November’s COP23 climate negotiations, calls for big polluters to be excluded from the talks are growing. Last May at the same ‘intersessional’ climate talks in Bonn, a group of countries representing more than 70 percent of the world’s population insisted on adding a conflict of interest provision in the negotiating text. It almost made it, were it not for an underhand move by the European Union and the USA which saw it removed. Pulling the strings behind such moves: the world’s largest fossil fuel companies. Taken to its logical conclusion, addressing conflicts of interest would mean kicking out the same corporations whose profits are built on causing climate change. Research shows that at least 80 per cent of known fossil fuel reserves need to be kept in the ground to keep global warming below 2 degrees, let alone 1.5 degrees. But a look at BP and Shell’s future energy projections allege that we can continue to burn fossil fuels indefinitely. Ending fossil fuels would put them out of business. This is a fundamental conflict of interest, yet getting it even discussed – let alone addressed – has been an uphill struggle. However, persistence of those countries at the frontline of climate change – particularly Ecuador, which is seeing increasing water shortages and crop failures – as well as increasing public outrage and civil society’s call on the UN to ‘Kick Big Polluters Out’ of climate policy, has ensured the issue has remained on the agenda. This year’s two-week intersessional talks in Bonn saw an official workshop on the topic organised by the secretariat of the United Nations Convention on Climate Change (UNFCCC). Read More here
