14 December 2017, The Conversation, Instead of congratulating ICAN on its Nobel Peace Prize, Australia is resisting efforts to ban the bomb. Earlier this week in Oslo, the 2017 Nobel Peace Prize was officially givento the International Campaign to Abolish Nuclear Weapons (ICAN), a global campaign that was launched in Melbourne in 2007. ICAN lobbied to establish a special UN working group on nuclear disarmament, campaigned for the UN General Assembly’s December 2016 resolution to launch negotiations on a prohibition treaty, and was an active presence at the UN conference that negotiated the treaty. Prime Minister Malcolm Turnbull failed to congratulate the Australian faces of ICAN, adding to the growing body of evidence of his flawed political judgement. There were no political downsides to phoning ICAN, noting the difference of opinion on the timing and means to effective nuclear disarmament, but warmly congratulating ICAN for the global recognition of its noble efforts to promote nuclear peace. Out of step with the global nuclear order The global nuclear order has been regulated and nuclear policy directions set by the Nuclear Non-Proliferation Treaty (NPT) since 1968. The 2015 Iran nuclear deal and North Korea’s unchecked nuclear and missile delivery advances show the benefits and limitations of the NPT respectively. The transparency, verification and consequences regime mothballed Iran’s bomb-making program by enforcing its NPT non-proliferation obligations. These will remain legally binding even after the deal expires in 2030. By contrast, the crisis over North Korea’s nuclear program has intensified within the NPT framework. Heightened geopolitical tensions in Europe, the Middle East and south and east Asia have further stoked nuclear fears. Meanwhile the NPT-recognised five nuclear weapon states have no plan to abolish their nuclear arsenals. Frustrated by the stubborn resistance of the nuclear weapon states to honour their NPT commitment to nuclear disarmament and alarmed by rising nuclear threats, on July 7 this year, 122 countries adopted a UN treaty to stigmatise and ban the bomb.

13 December 2017, World Weather Attribution, Climate Change Fingerprints Confirmed in Hurricane Harvey’s Record-Shattering Rainfall. Scientist with World Weather Attribution (WWA) find that human-caused climate change made the record rainfall that fell over Houston during Hurricane Harvey roughly three times more likely and 15 percent more intense.  WWA is releasing the findings of its new analysis regarding the role of human-induced climate change on Hurricane Harvey’s devastating rains that is published in the peer-reviewed journal, Environmental Research Letters (ERL). The findings are being released jointly with the American Geophysical Union (AGU) in a joint press release and at a press conference on Wednesday, December 13 at 2:30 p.m. CT at the annual AGU Fall Meeting in New Orleans.  The paper can be found on our website and in Environmental Research Letters.

13 December 2017, Renew Economy, AGL says batteries are coming, but coal is uninvestable. AGL says no private investor would invest in new coal plant, but says battery storage is coming and will be major game changer as costs fall – which may not be far away. Several days after formally rejecting federal government requests that it invest hundreds of millions of dollars to keep the ageing and increasingly decrepit Liddell coal generator open, AGL held an “investor day” where it said no private money would support a new coal generator. “We do not believe that any private capital will invest in new coal plants,” CEO Andrew Vesey told the assembled analysts. “Someone may say they want to, but that does not mean they will.” AGL over the weekend unveiled plans to replace Liddell, which include 653MW of wind farms, currently under construction, 300MW of new solar farms, a 250MW gas peaking plant, and small amounts of demand management. AGL over the weekend unveiled plans to replace Liddell, which include 653MW of wind farms, currently under construction, 300MW of new solar farms, a 250MW gas peaking plant, and small amounts of demand management. The later stages of the scheme – depending on what else happens in the market, and the make-up of energy policy – could see another 650MW of wind and solar, 250MW of battery storage, or pumped hydro, and possibly more gas peaking plants and more demand management. The AGL plan made it clear to the government that the cheapest way to provide reliability, and reduce emissions, was to shift from coal to renewables, something the Coalition is finding hard to accept. But Vesey’s comments were unequivocal, and appeared deliberately aimed at the lingering push from many in the conservative arena to build a new coal-fired generator. “The government may say it wants to … but it is becoming an increasingly risky proposition.” Read More here

13 December 2017, American Meteorological Society, Explaining Extreme Events from a Climate Perspective. This Bulletin of the American Meteorological Society (BAMS) special report presents assessments of how human-caused climate change may have affected the strength and likelihood of individual extreme events. This sixth edition of explaining extreme events of the previous year (2016) from a climate perspective is the first of these reports to find that some extreme events were not possible in a preindustrial climate. The events were the 2016 record global heat, the heat across Asia, as well as a marine heat wave off the coast of Alaska. While these results are novel, they were not unexpected. Climate attribution scientists have been predicting that eventually the influence of human-caused climate change would become sufficiently strong as to push events beyond the bounds of natural variability alone. It was also predicted that we would first observe this phenomenon for heat events where the climate change influence is most pronounced. Additional retrospective analysis will reveal if, in fact, these are the first events of their kind or were simply some of the first to be discovered. Read More here
