13 December 2016, Inside Climate News, ‘The Arctic Is Unraveling,’ Scientists Conclude After Latest Sobering Climate Report. The ill winds of climate change are irrevocably reshaping the Arctic, including massive declines in  sea ice and snow and a record-late start to sea ice formation this fall. Those were the sobering conclusions of the 2016 Arctic Report Card released Tuesday. The report card is sponsored by the  National Oceanic and Atmospheric Administration (NOAA) and co-authored by more than 50 scientists from Asia, North America and Europe. The data shows that the Arctic is warming at double the rate of the global average temperature. Between October 2015 and September 2016, temperatures over Arctic land areas were 2.0 degrees Celsius above the 1981-­2010 baseline, the warmest on record going back to 1900. The report, released at the American Geophysical Union meeting in San Francisco, clearly links the Arctic heatwave to a record-late start to formation of sea ice this fall, and to record high and low seasonal snow cover extent in the Northern Hemisphere. If the extreme warmth recorded in the Arctic this fall persists for the next few years, it may signal a completely new climate in the region, scientists said. Jeremy Mathis, director of NOAA’s Arctic Research Program, said the report highlights the clear and pronounced global warming signal in the Arctic and its effects cascading throughout the environment, like the spread of parasitic diseases in Arctic animals. “We’ve seen a year in 2016 like we’ve never seen before … with clear acceleration of many global warming signals. The Arctic was whispering change. Now it’s not whispering. It’s speaking, it’s shouting change, and the changes are large,” said co-author Donald Perovich, who studies Arctic climate at Dartmouth College. Sustained observations of the Arctic is crucial to making science-based policy decisions, he added, a goal threatened by the inclusion of numerous climate deniers in President-elect Donald Trump’s cabinet. This week, Trump’s transition team posted a new “Energy Independence” website that repeats his previous intentions to open up vast areas for fossil fuel development and to scrap existing climate action plans. Arctic ice doesn’t care about politics, and what happens in the region now is critically important to the U.S., said Rafe Pomerance, chair of Arctic 21 and a member of the Polar Research Board of the National Academies of Sciences, Engineering and Medicine.

13 December 2016, Carbon Brief, Some 33 US states have cut CO2 emissions while growing their economies over the past 15 years, according to new analysis from the Brookings Institution. These states show that economic growth can be compatible with tackling climate change. The US as a whole is one of at least 35 countries around the world to have achieved the same feat, by decoupling GDP growth and CO2 emissions between 2000 and 2014. “This success is an encouraging juncture in the campaign to limit global warming, and would seem to license cautious optimism,” write Devashree Saha and Mark Muro, the authors of the new research from the Brookings Institution’s Metropolitan Policy Program. “Yet now all of that is in question. With the stunning election of Donald Trump to the presidency, every aspect of the low-carbon paradigm for national and world progress has been thrown into doubt.” If the US federal government turns its back on climate mitigation, can individual sub-national bodies step up their own efforts? The authors explain: “Given their substantial powers to encourage emissions decoupling, states and cities are crucial players in the carbon drama. Therefore, it is worth assessing whether states’ and localities’ momentum on decoupling is strong enough to maintain recent progress.” For more discussion of the debate around decoupling, check out this recent Carbon Brief article.

12 December 2016, Climate News Network, Methane’s rapid spurt risks climate curbs plan. A recent rapid rise in methane could damage global attempts to slow climate change through cuts in carbon dioxide emissions. One year ago today, with huge relief, scarcely able to believe their achievement, world leaders finally agreed to reduce emissions of carbon dioxide. But a bare 12 months later comes sobering news: atmospheric concentrations of another gas, methane, are growing faster than at any time in the last 20 years, putting further pressure on the historic Paris Agreement to deliver substantial cuts in emissions very soon. Some scientists say the world now needs to change course and do more about methane to have a chance of keeping average global temperatures from rising by more than 2°C. And one seasoned Arctic watcher says the changes there in the last decade are altering a system which has remained intact since the Ice Age. Methane is the second major greenhouse gas, with agriculture accounting for 40% of emissions. Over a century it is 34 times more powerful as a greenhouse gas than carbon dioxide (though far less abundant), but over 20 years methane is 84 times more potent than CO2. In an editorial in the journal Environmental Research Letters, an international team of scientists reports that methane concentrations in the air began to surge around 2007 and grew steeply in 2014 and 2015. In those two years concentrations rose by 10 or more parts per billion annually. In the early 2000s they had been rising by an annual average of 0.5 ppb. Read More here

11 December 2016, The Guardian, On climate change and the economy, we’re trapped in an idiotic netherworld. The shrieks of horror that follow mentions of pricing carbon show politics remains wedded to the belief that economic growth trumps concerns of climate change. This week was a prime example of how economics and, by extension, politics doesn’t cope very well with the issue of climate change. The news that Australia economy went backwards in the September quarter was greeted with alarm by politicians and then used as a reason to push their policy barrow. And most of the barrows were piled high with coal. The treasurer and the prime minister in their press conferences on Wednesday made great mention of the need to keep electricity prices low for the economy to grow. Malcolm Turnbull especially was in full Tony Abbott 2010 mode out of a desire to cover the silly back flip on the issue of investigating whether or not to introduce an emissions intensity trading scheme. When asked about the prospect of GDP growth going backwards he immediately responded by suggesting the issue was for Bill Shorten to “explain why he is proposing to increase the price of electricity”. Never mind that such a scheme would more efficiently price emissions than does the current system, for now we remained trapped in an idiotic netherworld where any mention of pricing carbon (no matter how oblique) must be greeted with shrieks of horror, with the prime minister leading the chorus. And while you do wonder if Malcolm Turnbull ever looks in the mirror in the morning and asks himself how it all came to this – or whether he first rings Cory Bernardi to ask whether he is allowed to look into the mirror and ask such questions – the broader issue is that this netherworld is one that inherently sees action on climate change as a negative for the economy. And by contrast, the economic impact of anything that will cause climate change is seen as inherently positive.
