5 November 2015, Renew Economy, 50 years after warning, no debate in Paris on the science. Diplomats steeling themselves for a historic round of United Nations climate negotiations remain divided by a handful of stubborn disputes. Discord persists over financial and procedural issues, for example, and over how pollution from farming and deforestation should be addressed alongside energy generation. The fundamentals of climate science, however, are not among the issues being debated. The 50-year anniversary of the first detailed climate change warning issued to a U.S. president is Thursday, less than a month before a historic two-week climate negotiating session begins in Paris. The golden anniversary is coinciding with a rich embrace of climate science in global negotiations. “There are plenty of challenging issues for the negotiators, but the basic science of climate change is not one of them,” said Harvard University economics professor Robert Stavins, an expert on the talks. “So-called climate skepticism is essentially irrelevant to the outcome.” Countries that have been “trying to undercut international climate action,” including Malaysia and Saudi Arabia, often “play the bad guys,” said Jake Schmidt, director of the Natural Resources Defense Council’s international program, but “not by denying that climate change exists.” The carbon dioxide chapter of the 1965 Restoring the Quality of Our Environment report, produced by President Lyndon B. Johnson’s science advisory committee, cited climate change research dating back to 1899. The science in the chapter was “basically right,” said Ken Caldeira, an atmospheric science professor at Stanford University. It warned loosely of ice caps melting, seas rising, temperatures warming, and water bodies acidifying. In the five decades since, a frenzy of multidisciplinary scientific endeavours has helped humanity pinpoint and project, with increasing and worrying precision, the consequences of rising levels of atmospheric greenhouse gases. Meanwhile, those impacts have shifted from being hypothetical to being real. Read More here

5 November 2015, Washington Post, A controversial NASA study says Antarctica is gaining ice. Here’s why you should be skeptical. Late last week, a study published by NASA scientists in the Journal of Glaciology made the surprising claim that the gigantic continent of Antarctica is actually gaining ice, rather than losing it, to the tune of 82 gigatons (or billion metric tons) per year from 2003 to 2008. The study has drawn massive amounts of media attention — and no wonder. It contradicts numerous prior scientific claims, including a 2012 study in Science by a small army of polar scientists, a study from earlier this year in Earth and Planetary Science Letters (which found 92 gigatons of net losses per year) and this 2014 study in Geophysical Research Letters (160 gigatons of net losses per year). It also contradicts assertions by the leading consensus body of climate science, the U.N.’s Intergovernmental Panel on Climate Change, which stated in 2013 that Antarctica is “losing mass” and that this process is accelerating. That statement was itself based on multiple studies showing Antarctic ice loss. Not only does the new research fly in the face of all of this — if true, it also raises serious questions about our current understanding of sea level rise. If Antarctica is actually gaining ice, that means that a significant percentage of the current rise of the seas, estimated at roughly 3.22 millimeters per year by NASA itself, must be coming from elsewhere. (It takes 360 gigatons of ice to raise seas by 1 millimeter). No wonder, then, that a number of researchers have been quoted expressing skepticism about the new research, even as climate change doubters have had a field day — adding the study to an argumentative arsenal that previously included misleading claims about growing Antarctic sea ice.

5 November 2015, Climate News Network, ‘Dragon water’ could power the planet. The quest is on to develop new technology that can tap the intense heat deep below the Earth’s surface and supply the whole world with electricity. An ambitious project is being launched to drill deep into the Earth’s crust to harness super-heated “dragon water” that would generate massive quantities of renewable energy. Unlike traditional geo-thermal heat, which exploits hot rocks to produce steam for turbines, this project goes far deeper − to where the pressure and temperature are huge but the potential benefits are 10 times as great. There is an infinite amount of energy beneath the Earth’s crust. The problem is the technology to harness it. The European Union (EU) believes that deep drilling techniques developed by the oil industry can be adapted to extract the energy. It has earmarked €15.6 million for a project in which potentially the world’s most energy-rich geothermal well will be drilled at Larderello in Tuscany, Italy. Formidable challenge The technical challenges are formidable because of the intense heat and pressure that will turn steel brittle and wreck electrical equipment, so the plan is to develop engineering tools that can withstand the conditions. Iceland, which already exploits traditional geo-thermal energy successfully, has tried and failed to harness super-heated rock. But it has not given up, and a second attempt is being planned. The EU believes using oil company expertise in drilling deep wells will be the key to success. Read More here
5 November 2015, Carbon Brief, Q&A: What does the VW scandal mean for CO2 emissions? The Volkswagen (VW) emissions scandal spilled over into climate policy on Tuesday, after the company admitted to “irregularities” in its CO2 testing results. The firm’s share price — already down 60% after revelations it had deliberately cheated air pollution tests — fell a further 9% by Wednesday morning. However, the irregularities also have implications for CO2 emissions, as well as UK and EU climate targets. Carbon Brief investigates. What are CO2 test “irregularities”? On Tuesday, VW issued a “clarification” about the CO2 emissions testing of up to 800,000 of its vehicles in Europe. The statement says: “During the course of internal investigations irregularities were found when determining type approval CO2 levels…It was established that the CO2 levels and thus the fuel consumption figures for some models were set too low during the CO2 certification process.” Though the precise nature of these problems remains unclear, it has attracted wide media coverage. The Times notes petrol cars have become embroiled in the scandal for the first time. The BBC says the “dirty laundry” is piling up for VW. The Guardian says VW might have manipulated CO2 tests, in addition to its now-notorious “defeat device” for NOx air pollution. The New York Times says VW’s pollution problems have taken a “costly new turn”. A Guardian live-blog says costs for VW could exceed the €2bn it has set aside. Current EU regulations limit car CO2 emissions to no more than 130 grammes of CO2 per kilometre, notes Politico. This is set to fall to a fleet-wide average of 95gCO2/km in 2020. In the UK, vehicle excise duty is linked to CO2 emissions meaning some cars may have had unduly low rates, says Autocar. The Telegraph says some drivers could face higher taxes. However, this year’s budget changed the rules to decouple car tax and CO2 emissions from 2017. Read More here
