26 July 2015, DeSmog, Senators Call For End To Arctic Drilling As Shell Gets Permits To Begin Work In Chukchi Sea: Shell received the final permits it needed to begin drilling exploratory wells in the Chukchi Sea last Wednesday, but a group of Senators led by Oregon’s Jeff Merkley is calling for a ban on Arctic drilling altogether. According to the Associated Press, the permits are somewhat conditional: In granting the company the green light, the Department of the Interior said Shell can only drill the top sections of wells, or to about a depth of 1,300 feet, because critical emergency response gear, including a well-capping device in the event of a blowout or leak, will not be present for the foreseeable future. The capping stack and other emergency gear is on board the MSV Fennica, which is in Portland, Oregon for repairs after Shell opted to send the ship out of Dutch Harbor, Alaska on July 3 via a shallow and evidently treacherous route, choosing speed over safety. The Fennica is an icebreaker — a ship literally designed to break through ice, one of two such ships in Shell’s Arctic fleet meant to protect its drill rigs from unsafe ice conditions. But the Fennica somehow suffered a gash in its hull more than 3 feet long before even leaving the harbor and was forced to head immediately back to port. There is no word on how long the repairs will take. When the capping stack is available to be deployed within 24 hours, aDOI spokesperson told the Associated Press, Shell can apply for an amended permit that would allow the company to drill deeper. That is cold comfort to critics of Shell’s Arctic drilling plans, who have repeatedly pointed out that the remote Arctic waters of the Chukchi Sea, where the company plans to drill, will make cleanup of any spill extremely difficult even if Shell has all of its emergency gear on hand. An oil spill would be devastating, environmentalists argue, but any drilling activities are likely to be incredibly disruptive in the fragile Arctic ecosystem. Read More here

26 July, The Economist, The global addition to energy subsidies: Energy prices have been falling for a year. Over the last month that trend has accelerated. On July 24th, the price of a barrel of oil in America reached a low of $48. In spite of this, governments are still splurging on subsidies to prop up production. Fossil fuels are reaping support of $550 billion annually, according the International Energy Agency (IEA), an organisation that represents oil- and gas-consuming countries, more than four times those given for renewable energy. The International Monetary Fund’s estimates are substantially higher. It said in May that countries will spend $5.3 trillion subsiding oil, gas and coal in 2015, versus $2 trillion in 2011. That is equivalent to 6.5% of global GDP, and is more than what governments across the world spend on healthcare. At a time of low energy prices, high government debt and rising concern over emissions there is scant justification for such spending. So why is the world addicted to energy subsidies? Read More here
24 July 2015, The Conversation, The ‘mini ice age’ hoopla is a giant failure of science communication. This month there’s been a hoopla about a mini ice age, and unfortunately it tells us more about failures of science communication than the climate. Such failures can maintain the illusion of doubt and uncertainty, even when there’s a scientific consensus that the world is warming. The story starts benignly with a peer-reviewed paper and a presentation in early July by Professor Valentina Zharkova, from Northumbria University, at Britain’s National Astronomy Meeting. The paper presents a model for the sun’s magnetic field and sunspots, which predicts a 60% fall in sunspot numbers when extrapolated to the 2030s. Crucially, the paper makes no mention of climate. The first failure of science communication is present in the Royal Astronomical Society press release from July 9. It says that “solar activity will fall by 60 per cent during the 2030s” without clarifying that this “solar activity” refers to a fall in the number of sunspots, not a dramatic fall in the life-sustaining light emitted by the sun. The press release also omits crucial details. It does say that the drop in sunspots may resemble the Maunder minimum, a 17th century lull in solar activity, and includes a link to the Wikipedia article on the subject. The press release also notes that the Maunder minimum coincided with a mini ice age. But that mini ice age began before the Maunder minimum and may have had multiple causes, including volcanism. Crucially, the press release doesn’t say what the implications of a future Maunder minimum are for climate. Read More here
23 July 2015, New York Times, Whiplash Warning When Climate Science is Publicized Before Peer Review and Publication: The study is “Ice Melt, Sea Level Rise and Superstorms: Evidence from Paleoclimate Data, Climate Modeling, and Modern Observations that 2°C Global Warming is Highly Dangerous.” The 66-page “discussion paper” (the authors’ description) was posted Thursday in Atmospheric Chemistry and Physics Discussions, the discussion forum of the European Geosciences Union journal Atmospheric Chemistry and Physics. The paper was was written by 17 prominent climate, ice and ocean scientists, led by James E. Hansen, the pioneering climatologist who since 2007 has argued that most of his peers have been too reticent in their projections of the possible pace of sea-level rise in a warming world. It is a sweeping and valuable cross-disciplinary description of ways in which climate and ocean dynamics, pushed by the planet’s human-amplified greenhouse effect, could accelerate sea level rise far beyond the range seen as plausible in the last report from the Intergovernmental Panel on Climate Change and the most recent review of what leading experts on sea level think, this 2014 paper: “Expert assessment of sea-level rise by AD 2100 and AD 2300.” Read More here
