10 December 2015, The VERB, The 1.5 Placebo.Moments before the Paris climate agreement is to be decided upon, the draft text (as of 3pm Wednesday) still contains three different options surrounding its overall objective. The draft retains options to limit warming to below 2°C, below 1.5°C, or ‘well’ below 2°C with mention of scaling up efforts to stay below 1.5°C. As The Verb reported earlier in the week, half a degree of difference is highly economically significant, and for vulnerable nations may be the difference between persistence and functional destruction. For many small island states, a target of 1.5°C has been a long held objective that has gained increasing support in Paris. “To hold the temperature within 2°C is not an acceptable goal,” said Barbados Environment Minister Dr. Denis Lowe, who argued that “the goal should be 1.5°C, that is what will keep us alive.” Day one of the negotiations saw leaders of 106 states sign a statement calling for 1.5°C to become the long-term temperature goal. This was in lieu of the 2°C target, established in the 2009 Copenhagen meeting. Canada, France, Germany, the UK, Australia, China, and the US have since expressed support for including the 1.5°C target in some capacity. At first glance, this shift sounds good – it may even make people feel better about the possibility of avoiding the worst impacts of climate change. But it appears to be a placebo, and it may come at the expense of more effective responses. The challenge of limiting warming to below 1.5°C is enormous given current carbon dioxide concentrations and emissions. Some call it unfeasible. There are currently 400 parts per million of carbon dioxide in the atmosphere, a number that is growing at two parts per million per year. New research suggests that we would have to stabilise concentrations between 420 and 440 parts per million by 2100 to have even a 50% chance of holding warming below 1.5°C. 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. Read More here
