26 October 2015, Washington Post, Scientists confirm that East Antarctica’s biggest glacier is melting from below. Earlier this year, we learned some worrisome climate news. Although Antarctic scientists have been most concerned about loss of ice in the western part of Antarctica, a study in Nature Geoscience suggested a vulnerability in the much larger ice sheet of East Antarctica, as well. East Antarctica’s enormous Totten Glacier, you see, has a key similarity with the glaciers of West Antarctica — namely, it is rooted deep below sea level. This means that it is potentially exposed to warm ocean waters, and the study in March uncovered a deep and 5-kilometer wide subsea valley beneath the glacier’s oceanfront ice shelf that, the authors said, could be a route for warm offshore water to reach its base. This might explain why the glacier has been observed to be thinning and lowering, or losing elevation, over time, they noted. Located along East Antarctica’s Sabrina Coast, Totten glacier is the ice sheet’s largest. It holds back 3.9 meters of potential sea level rise, or over 12 feet, and connects with the very deep and vast Aurora Subglacial Basin, which is also rooted well below sea level. So the results were treated as being of enormous consequence. But they’re not the end of the story, as there is vastly more to learn about Totten glacier. A new study out in Geophysical Research Letters reaffirms some of these core concerns about Totten’s melt — while also appearing to partly alleviate others. Read More here

26 October 2015, Climate News Network, Bonn climate talks fail to cut rich-poor divide. Negotiations to smooth the way towards a new global agreement on tackling climate change ended without closing deep rifts between developed and developing countries. The world is hoping for a positive outcome at theUN climate change conference in Paris in early December to head off potentially catastrophic climate change. Judged by the outcome of a five-daypreparatory meeting in Bonn, the outlook is not good. Once again, delegates from around the world argued about cash, with developing and poorer countries accusing wealthier nations of reneging on promises to provide more money to fight a warming climate and adapt to climate change. The developing world argues that many poorer countries are already feeling the effects of climate change – caused mainly by the greenhouse gas emissions of the richer nations. Nozipho Mxakato-Diseko, from South Africa, speaking on behalf of more than 130 developing countries, including China, told delegates at the talks in Germany that rich countries had be ready to provide far more financial assistance to help poorer nations, which were already having to deal with climate change.

26 October 2015, Carbon Brief, Old battlelines resurface as countries meet for last time ahead of Paris climate summit. Countries have completed the last round of negotiations before a landmark meeting in Paris in December, where they have agreed to sign a new UN agreement on climate change. Despite the urgency, the week produced little consensus, with issues such as finance proving fractious till the end. Nonetheless, parties produced a new draft text, which will form the basis of the final negotiations in Paris. The document does little to narrow down the options for the final deal, but crystallizes the key debates that negotiators and ministers will attempt to resolve in just over a month’s time. Christiana Figueres, the executive secretary of the UNFCCC, told the Chatham House climate conference in London today that the new text was “now party owned” and, as a result, was “not biased, but balanced”.

26 October 2015, Renew Economy, Paris climate talks: Now it’s up to Turnbull to save the planet. The last official round of negotiations before the Paris climate change talks have broken up in Bonn, with some progress made but a global climate deal still needing fresh impetus from political leaders to put the world on a course to rapidly decarbonise the global economy. In Bonn, after a week of talks, a 20-page text was expanded to 63 pages, and will need to be cut back. But at least there appears to be agreement on what needs to be resolved. The principal blockages remain around the scale of ambition, and on issues such as finance and the concept of “loss and damage”. The UN has what it says is a “manageable” text and a good “starting point” for negotiations. The text, say observers, has been expanded as each country or bloc inserts their own “bargaining” chip. They say it is now time for the leaders to step in. Which is why the success or failure of the Paris talks will depend on the likes of Australian prime minister Malcolm Turnbull, the newly elected Canadian PM Justin Trudeau, and of course the major players in the world economy – US president Barack Obama, China’s Xi Jinping, India’s Rajendrah Modi, and the European Union. Over the next few weeks a series of meetings will be held to try to resolve some of those issues. A pre-Paris ministerial meeting will take place in the French capital from November 8-10, which will be attended by environment minister Greg Hunt. Read More here
