22 November 2016, The Guardian, ‘Extraordinarily hot’ Arctic temperatures alarm scientists. The Arctic is experiencing extraordinarily hot sea surface and air temperatures, which are stopping ice forming and could lead to record lows of sea ice at the north pole next year, according to scientists. Danish and US researchers monitoring satellites and Arctic weather stations are surprised and alarmed by air temperatures peaking at what they say is an unheard-of 20C higher than normal for the time of year. In addition, sea temperatures averaging nearly 4C higher than usual in October and November. “It’s been about 20C warmer than normal over most of the Arctic Ocean, along with cold anomalies of about the same magnitude over north-central Asia. This is unprecedented for November,” said research professor Jennifer Francis of Rutgers university. Temperatures have been only a few degrees above freezing when -25C should be expected, according to Francis. “These temperatures are literally off the charts for where they should be at this time of year. It is pretty shocking. The Arctic has been breaking records all year. It is exciting but also scary,” she said. Read More here

22 November 2016, One Step off the Grid, Victoria town (Newstead) calls for partners for 100% renewable energy plan. he Victorian town of Newstead is seeking proposals from potential project partners who could help refine its plan to reach 100 per cent renewable energy within 5 years, and which could act as a blue-print for other towns in the state to follow. Newstead, a town of around 500 people, is considered a flagship project project for the state, and is looking to build up its renewable energy capacity and then integrate these into the local grid with battery storage and new “energy market” ideas. Tosh Szatow, director for Energy for the People, which is advising the township, says the call for expressions of interest is designed to flush out ideas from solar companies, retailers, trading platforms and others that could be adapted to the town’s plans. “We have sketched out a plan, and know what a model could look like,” Szatow says. “Now we want to test some of this thinking and identify some of the partners that could help in the project.” The Newstead plan is seen as a fore-runner for other towns and cities in the state, and elsewhere in Australia. And far from being a rogue proposal, the idea has the support of the state Labor government and even the local network operator, Powercor, which is co-operating on data, network capacity and tariff design.

22 November 2016, Renew Economy, Climate conspiracy grips Senate as Coalition attacks latte-sipping opponents of coal. The influence of president-elect Donald Trump’s attack on “elites” is taking hold in the Australian parliament, with the Coalition attacking “latte-sipping” opponents of coal mining and joining enthusiastically in a debate questioning climate science in the Senate. Frydenberg was asked in question time by Greens MP Adam Bandt about a US government report delivered in at the Marrakech climate talks that warned, amongst other things, of a 1.5m rise in sea levels by 2050 if greenhouse emissions continued at current levels. Frydenberg responded by claiming that Australia had an “ambitious” climate target for 2030 and had been praised “for innovation” and its work on carbon capture and storage at the recent climate talks in Marrakech. A few hours later, Canada announced it would phase out traditional coal fired generation by 2030 as part of its “vision for a clean growth economy”. The UK is phasing out coal by 2023, and France is phasing out coal too, although it has taken a rain check on that idea because one third of its nuclear fleet are sidelined by safety concerns.“It it is okay for the member for Melbourne to put his sandals up on the seat, sip his soy latte, sit in the streets of Brunswick and say that it is the end of coal,” but coal would continue to be part of the mix for decades to come, Frydenberg said.

21 November 2016, Yale Climate Connections, Fuel Cells: Promising, but struggling to catch on. Fuel cells are efficient, generate clean electricity, and they run around the clock. So why aren’t we using them on a mass scale? Fuel cells have been the next best clean-energy thing for, well, a long time. The byproducts of that reaction are heat and water. The heat can be recycled into the fuel cell itself and/or used for external heating and cooling – generally referred to as combined heat and power. That makes stationary fuel cells – the kind used for electricity, as opposed to ones used in vehicles – extremely efficient and as clean an energy source as solar and wind.A technology with roots in the 1800s and modern-day use in every NASA-manned space flight from Apollo through the end of the space shuttle program, fuel cells just kind of look like a big box. Inside, they electrochemically combine hydrogen and the oxygen from ambient air to create electricity. But because the hydrogen source for most fuel cells comes from natural gas, they are generally not considered renewable, leaving them in an environmental limbo. Read More here
