9 December 2015, Renew Economy, Paris, COP21: Australia digs in on fossil fuels, sees coal as solution to hunger. One of the big themes of the Paris climate talks has been the focus on renewable energy – wind and solar in particular – as a means to reach emission reduction pledges, and cut pollution in the cities. Australia’s Coalition government, however, is sticking to a familiar theme: it has invested heavily in fossil fuels with long-life assets it is keen to retain and, anyway, coal is still good for humanity. Foreign minister Julie Bishop used a forum hosted by Indonesia called “Pathways to a Sustainable Low Carbon and Climate Resilient Economy” to push the case for Australian fossil fuels. “Right now we are in a transition phase,” Bishop said. “Traditional energy sources, fossil fuels like coal, will remain a significant part of the global energy mix for the foreseeable future. “Barring some technological breakthrough fossil fuels will remain critical to promoting prosperity, growing economies and alleviating hunger for years to come.” Hunger? It seems a variation of the “coal is good for humanity” theme, despite repeated estimates by the likes of the IEA, the World Bank and others that suggest the needs of poor countries are probably best served by renewable energy. The comments yet again underline the disconnect between Australia’s apparent support for a global target of “well below 2°C” and its lack of policies to get its economy beyond the fossil fuel age – few renewables are being built and none of the major coal generators are being closed. Bishop suggested this would be the status quo. “It is a fact that energy is the mainstay of our respective countries’ export markets and underpins economic growth,” she said. “The capital stock and infrastructure we have in stock to create and supply energy, both fossil fuels and renewables, have long life spans.” So no early closures then. Read more here

9 December 2015, Climate News Network, Ice melt highlights Inuit plight. COP21: As Arctic peoples’ leaders appeal for unity to halt global warming, scientists report that Greenland’s glaciers are now melting at a speed not seen since the last Ice Age. The glaciers of Greenland are retreating two to three times faster now than at any time since the last Ice Age ended 9,500 years ago, according to new research. The news comes as indigenous peoples from the northern polar region staged anArctic Day at the COP21 climate change summit in Paris. Leaders of Greenland peoples, the Nunavut region of Canada and the Inuit Circumpolar Council appealed to the governments of the world to unite to dramatically reduce greenhouse gas emissions and keep global warming to between 1.5˚C and 2˚C. That is because the Arctic is now warming faster than almost anywhere else on Earth, and both human settlements and natural ecosystems are vulnerable. That the Greenland glaciers are in retreat is itself not news. Satellite data and measurements on the ground have repeatedly confirmed the retreat of the glaciers, the loss of ice and the acceleration of flow. The Jakobshavn Isbrae glacier has even reached a speed of 17 kilometres a year. Sediment cores But US scientists report in Climate of the Past journal that the present rate of loss is without precedent.

9 December 2015, Climate News Network, Climate heads for irreversible change. COP21: With the UN climate conference still trying to agree an effective way to tackle global warming, a scientific group warns that policy is ignoring the reality of a melting world. PARIS, 9 December, 2015 – Some of the world’s coldest places, on land and sea, may be plunged into an unstoppable transition to a climate system most scientists believe has not existed for 35-50 million years. The almost immediate consequences would include the loss of reliable water resources for millions of people, and the start of a process leading to ultimate sea level rise of 4-10 metres or more. The warning comes in a report by the International Cryosphere Climate Initiative (ICCI), a group of scientists, diplomats and others who say climate change “is happening in the cryosphere faster and more dramatically than anywhere else on earth”. The report says that unless the negotiators at the COP21 climate change summit in Paris show far more ambition than they have so far, the verdict on this conference will be “too little, too late”. Cryosphere dynamics Pam Pearson, ICCI’s founder and director, introduced the report on the risks of irreversible climate change in the cryosphere − the scientific name for the parts of the world that are covered in ice and snow for part or all of the year – by saying: “We are worried by the disconnect between cryosphere dynamics and the policy response.” Read More here

9 December 2015, Washington Post, How the Earth itself could undermine a Paris climate agreement. PARIS — With only three days left, tensions here are rising as countries race to resolve outstanding differences and forge an agreement that — hopefully — will set the planet on a path to avoiding the worst consequences of climate change. The goal is an agreement that would set the world on a path to limit warming to below 2 degrees Celsius, or perhaps even 1.5 degrees Celsius, above pre-industrial levels. But at a news conference here at the Le Bourget conference center Wednesday morning, scientists pointed out a factor that could make hitting these targets quite a lot harder. It’s called permafrost. As the planet warms, this frozen northern soil is going to continue to thaw — and as it thaws, it’s going to release carbon dioxide and methane into the air. A lot of it, it turns out. Potentially enough to really throw off the carbon budgets that have been calculated in order to determine the maximum emissions that we can release and still have a good chance of keeping warming to 2 C or below it. In particular, Susan Natali of the Woods Hole Research Center explained Wednesday that with a very high level of warming, permafrost emissions this century could be quite large indeed. Natali used numbers from the 2013 report of the United Nations’ Intergovernmental Panel on Climate Change, which found that humans can only emit about 275 more gigatons, or billion tons, of carbon (about 1,000 gigatons of carbon dioxide, which has a greater molecular weight) to have a greater than 66 percent chance of limiting warming to 2 degrees C. But out of that limited budget, she said, permafrost emissions could take up some 150 of those gigatons (or about 550 gigatons of carbon dioxide).
