13 November 2015, Climate News Network, Global warming drains the water of life. Melting snowpack in Turkey’s Lesser Caucasus mountains. New research warns that rising temperatures are reducing the mountain snow on which billions of people in lowland areas depend for their water supply. Up to two billion people who depend on winter snow to deliver their summer water could see shortages by 2060 as upland and mountain snowpacks continue to dwindle. An estimated 300 million people could find, 45 years on, that they simply won’t have enough water for all their needs, according to new research. Climate change driven by rising atmospheric levels of carbon dioxide – in turn, fed by human combustion of fossil fuels – may already be affecting global precipitation. Researchers have consistently found that much of the world’s drylands will increase as global average temperatures rise. But warmer temperatures increasingly also mean the water that once fell as snow, to be preserved until the summer, now falls as winter rain, and runs off directly. The snow that does fall is settling at ever higher altitudes and melting ever earlier. Reliable flow This is bad news for agricultural communities that depend on a reliable flow of meltwater every summer. California is already in the grip of a sustained drought, made worse by lower falls of snow. Great tracts of Asia depend on summer meltwater from the Himalayan massif and the Tibetan plateau. Justin Mankin, an environmental scientist at Columbia University’s Earth Institute in the US, and colleagues report in Environmental Research Letters journal that they studied 421 drainage basins across the northern hemisphere.

13 November 2015, Renew Economy, Malcolm Turnbull was right: Direct Action is a climate con. You’ve got to hand environment minister Greg Hunt a capital A for Audacity. Or maybe a capital C for Chutzpah. Round two of the government’s emissions reduction fund – the central plank of its Direct Action plan – has come and gone, another $557 million has been spent making some farmers and carbon traders a lot richer than they used to be, and Hunt is still insisting that it is the greatest success in the history of emissions reductions. Ever. “In the lead up to Paris, this government has once again demonstrated that we can significantly reduce emissions and tackle climate change without a carbon tax and increased electricity prices,” he press released on Thursday. It’s easy to claim a triumph with rhetoric, but not so easy to do so with the numbers. Here is what the government has claimed to have done: It has cherry picked, presumably on the basis of price and authenticity, some 131 projects – mostly in vegetation and savannah burning, but also some in landfill gas and energy efficient lighting – that will deliver 45 million tonnes of abatement at an average of $12.25 each, over 10 years. Hunt – outrageously – says this is a price that is just one per cent of the carbon price under Labor. Dubiously, he says it will deliver on the government’s (modest) emissions reduction targets – minus 5 per cent from 2000 levels by 2020, and minus 19 per cent on 2000 levels by 2030. Everyone involved in this charade is keeping mum – or their hands firmly on the wads of cash now in their wallets – about what they really think. They have been dicked around so much by the coming and going of the CPRS and the carbon price, that they feel they deserve something, and wads of cash from a government auction is fair game. If a government is determined to force money into their pockets for doing something that their clients may well have done anyway (growing trees, not clearing other vegetation, continuing landfill gas operations), then who are they to argue. But here are a couple of key stats to put it into perspective.

13 November 2015, The Conversation, Australia’s climate targets still out of reach after second emissions auction. The government’s Clean Energy Regulator yesterday announced the results of the second “reverse auction”. It spent A$557 million to buy emissions cuts of some 45 million tonnes of carbon dioxide. Australia needs to cut its CO₂ emissions by 236 million tonnes to meet its current 2020 mitigation target of -5% below 2000 levels. The Direct Action Plan and its Emissions Reduction Fund (ERF) is the Turnbull government’s major program for doing so. The first auction, in April this year, spent A$660 million for 47.3 million tonnes. So far, then, almost half of the A$2.55 billion allocated to the ERF has been used and some 92.8 million tonnes of emissions reduction “bought” at an average rate of almost A$13.12 per tonne of CO₂. The ERF will also form part of efforts to achieve Australia’s 2030 climate target. The latest round of UN climate negotiations begins in Paris in three weeks’ time. These talks aim to produce tougher national greenhouse targets for the decade to 2030. Ironically, the focus on Paris is drawing attention away from the urgency of emissions cuts that need to be delivered beforehand. In Australia, the Paris talks encourage us to accept as given our 2020 target of -5% below 2000 emissions levels, although it is among the weakest of national mitigation efforts for that period. They encourage us to ignore the fact that – according to criteria accepted by both Labor and Coalitions governments and now met because of the rising ambitions and efforts of major emitters elsewhere – Australia’s target should have increased to -15% by 2020. It is against this second benchmark that the Turnbull government’s efforts should now be measured.

13 November 2015, Carbon Brief, Explainer: The legal form of the Paris climate agreement. The aim of the UN summit in Paris is to seal a universal, international agreement on avoiding dangerous climate change, that has legal force. In broad terms, this means the Paris agreement is almost certain to include a legally binding treaty at its core, despite headlines to the contrary. Yet the treaty’s precise legal form remains unclear. What will the treaty bind countries to do? Will it even be called a treaty? Carbon Brief has read the lengthy legal texts and spoken to the experts on the legal form of the Paris climate agreement — and whether the legal form matters.
