18 October 2015, Climate News Network, Climate changes can kick in below 2°C limit. Sudden shifts in settled climates can occur long before global warming reaches the internationally-agreed safety level, European scientists say. Climate change could arrive with startling speed. New research has identified at least 37 “tipping points” that would serve as evidence that climate change has happened – and happened abruptly in one particular region. And 18 of them could happen even before the world warms by an average of 2°C, the proposed “safe limit” for global warming. Weather is what happens, climate is what people grow to expect from the weather. So climate change, driven by global warming as a consequence of rising carbon dioxide levels, in response to more than a century of fossil fuel combustion, could be – for many people – gradual, imperceptible and difficult to identify immediately. But Sybren Drijfhout, of the University of Southampton in the UK and his collaborators in France, the Netherlands and Germany, are not so sure. They report in the Proceedings of the National Academy of Sciences that they “screened” the massive ensemble of climate models that inform the most recent reports from the Intergovernmental Panel on Climate Change, and found evidence of abrupt regional changes in the ocean, the sea ice, the snow cover, the permafrost and in the terrestrial biosphere that could happen as average global temperatures reached a certain level. The models did not all simulate the same outcomes, but most of them did predict one or more abrupt regional shifts. No safe limit. But the future is not an exact science. “Our results show that the different state-of-the-art models agree that abrupt changes are likely, but that predicting when and where they will occur remains very difficult,” said Professor Drijfhout. “Also, our results show that no safe limit exists and that many abrupt shifts already occur for global warming levels much lower than two degrees.” The idea of a “tipping point” for climate change has been around for decades: the hypothesis is that a climate regime endures – perhaps with an increasing frequency of heat waves or windstorms or floods – as the average temperatures rise. However, at some point, there must be a dramatic shift to a new set of norms.Read More here

12 October 2015, Climate News Network, Climate cash flow to poorer nations is still too slow. Rich countries are failing to fulfil pledges to make billions of dollars available to help the developing world tackle climate change. World leaders are not delivering fully on agreements made at successive climate negotiations to channel US$100 billion annually from rich countries to poor in order to tackle and adapt to climate change. An analysis of cash flows by the Organisation for Economic Co-operation and Development(OECD) − which links the world’s wealthier countries − finds the target due to be reached by 2020 is still far from being met. The OECD says that, at present, the rich countries are channelling on average about $57bn each year to help poorer nations limit carbon emissions and deal with extreme weather events and rising sea levels. Complex business It has spent several months trying to gauge climate-related cash flows from rich to poor countries − a complex business involving analysis of foreign aid budgets, loans from public and private bodies, and other sources of cash. “Our estimates paint an encouraging picture of progress,” says Angel Gurria, the OECD secretary-general. “We are about halfway in terms of time and more than halfway there in terms of finance, but clearly there is still some way to go.” However, whether or not the wealthier countries are making sufficient commitments will be a key item on the agenda at the major negotiations on climate change being held in Paris in late November and early December this year.

12 October 2015, Yale Environment 360, The Rapid and Startling Decline Of World’s Vast Boreal Forests. Scientists are becoming increasingly concerned about the fate of the huge boreal forest that spans from Scandinavia to northern Canada. Unprecedented warming in the region is jeopardizing the future of a critical ecosystem that makes up nearly a third of the earth’s forest cover. The boreal forest wraps around the globe at the top of the Northern Hemisphere in North America and Eurasia. Also known as taiga or snow forest, this landscape is characterized by its long, cold and snowy winters. In North America it extends from the Arctic Circle of northern Canada and Alaska down into the very northern tip of the United States in Idaho, Washington, Montana, and Minnesota. It’s the planet’s single largest biome and makes up 30 percent of the globe’s forest cover. Moose are the largest ungulate in the boreal, adapted with their long legs to wade in its abundant marshes, lakes and rivers eating willows, aspen and other plants. In the southern boreal forest of northern Minnesota, moose were once plentiful, but their population has plummeted. Thirty years ago, in the northwest part of the state, there were some 4,000; they now number about a hundred. In the northeast part, they have dropped from almost 9,000 to 4,300. They’ve fallen so far, so fast that some groups want them listed as endangered in the Midwest. Read More here
8 October 2015, The Conversation, FactCheck: does Australia co-operate with the UN on its human rights obligations? At its narrowest interpretation, Brandis is correct: at a purely procedural level, it is true that Australia does comply with its formal obligations to report to the UN, and has issued an open invitation for UN investigators called Special Rapporteurs to visit. However, taken more broadly, Brandis overstates Australia’s human rights record i relation to the UN. Australia has been widely criticised, including by the UN, for its weak compliance with substantive obligations to respect, protect and fulfil human rights. Australia and the UN The “UN envoy” that Insiders host Barrie Cassidy mentions is United Nations Special Rapporteur on the Human Rights of Migrants, Francois Crepeau. To understand Brandis’ reply, we must first understand the role of a Special Rapporteur. The UN Human Rights Council is a body established by the UN General Assembly to oversee human rights compliance by UN member countries (“states”). The UN uses what it calls “special procedures” for this purpose, such as Special Rapporteurs, Independent Experts and Working Groups, to investigate and report on human rights issues, or the situation in particular states. Current issues under investigation include education, food, freedom of expression, and indigenous peoples. A special procedures visit to a state is only by invitation, and so a request is made for an invitation from a state. Some states issue the requested invitation and some don’t. Some states have issued a standing invitation, indicating a willingness to receive visits at any time. Australia issued a standing invitation in 2008, before which it agreed to every request it had received. Under the standing invitation, Australia has received special procedure visits on Indigenous people, health, foreign debt, and people trafficking; previously it received visits on freedom of religion or belief, contemporary forms of racism, arbitrary detention, and adequate housing.
