26 June 2017, Washington Post, Sea level rise isn’t just happening, it’s getting faster. In at least the third such study published in the past year, scientists have confirmed seas are rising, and the rate of sea level rise is increasing as time passes — a sobering punchline for coastal communities that are only now beginning to prepare for a troubling future. What was a 2.2 millimeter per year rise in 1993 was a 3.3 millimeter rise in 2014, based on estimates of the mass changes of a number of key components of sea level rise, such as the melting of the Greenland and Antarctic ice sheets, the study in Nature Climate Change found. That’s the difference between 0.86 and 1.29 inches per decade — and the researchers suggest further sea level acceleration could be in store. The chief cause of the acceleration was the melting of the Greenland ice sheet, which went from contributing under 5 percent of all sea level rise in 1993 to contributing over 25 percent in 2014, the study found. The loss of ice in Antarctica and smaller glaciers over the same time period also contributed to quicker sea level rise. The increase in the rate of sea level rise “highlights the importance and urgency of mitigating climate change and formulating coastal adaptation plans to mitigate the impacts of ongoing sea level rise,” write Xianyao Chen of the Ocean University of China and Qingdao National Laboratory of Marine Science and Technology, and colleagues. Chen’s co-authors hailed from institutions in China, Australia and the United States. “We understand why the sea level is accelerating and we’re understanding what the components are contributing,” said Christopher Harig, one of the study’s authors and a researcher at the University of Arizona. Earlier this year, a different group of researchers found sea level rise was only about 1.1 millimeters per year before 1990, whereas in the period between 1993 through 2012 it was 3.1 millimeters per year. NASA, at present, puts the rate of sea level rise at 3.4 millimeters per year. But while the individual estimates differ, the broader picture is that researchers generally agree that the rate of sea level rise is increasing — and that this will have major consequences for coastal regions, which will have less time to adapt if sea level rise acceleration continues.

22 June 2017, Renew Economy, Australia’s new citizenship test: swear allegiance to Queen and Coal. The Coalition government’s new citizenship test appears to include talking points that might have been prepared by the coal industry in defending their role in climate change.Details of the extraordinarily complex reading material that new citizens are being asked to comprehend, in preparation for their citizenship tests, have been revealed in The Australian newspaper, which was concerned by the level of complexity in the language. What struck us at RenewEconomy from the examples used by The Australian was the nature of the content. It looked like marketing spiel from the coal industry, so we checked it out further. Take this, for example: “Clean coal is another avenue for improving fuel conversion efficiency. Investigations are under way into super-clean coal (35 per cent ash) and ultraclean coal (less than 1 per cent ash). Super-clean coal has the potential to enhance the combustion efficiency of conventional pulverised fuel power plants.” And on it goes. You can read more here. But having absorbed this, the hopeful new citizen is then given some practice multiple choice questions. Such as: Read More here and be astounded by the audacity!
15 June 2017, New York Times, The Dutch Have Solutions to Rising Seas. The World Is Watching. In the waterlogged Netherlands, climate change is considered neither a hypothetical nor a drag on the economy. Instead, it’s an opportunity……No place in Europe is under greater threat than this waterlogged country on the edge of the Continent. Much of the nation sits below sea level and is gradually sinking. Now climate change brings the prospect of rising tides and fiercer storms. From a Dutch mind-set, climate change is not a hypothetical or a drag on the economy, but an opportunity. While the Trump administration withdraws from the Paris accord, the Dutch are pioneering a singular way forward. It is, in essence, to let water in, where possible, not hope to subdue Mother Nature: to live with the water, rather than struggle to defeat it. The Dutch devise lakes, garages, parks and plazas that are a boon to daily life but also double as enormous reservoirs for when the seas and rivers spill over. You may wish to pretend that rising seas are a hoax perpetrated by scientists and a gullible news media. Or you can build barriers galore. But in the end, neither will provide adequate defense, the Dutch say. And what holds true for managing climate change applies to the social fabric, too. Environmental and social resilience should go hand in hand, officials here believe, improving neighborhoods, spreading equity and taming water during catastrophes. Climate adaptation, if addressed head-on and properly, ought to yield a stronger, richer state. This is the message the Dutch have been taking out into the world. Dutch consultants advising the Bangladeshi authorities about emergency shelters and evacuation routes recently helped reduce the numbers of deaths suffered in recent floods to “hundreds instead of thousands,” according to Mr. Ovink.

14 June 2017, Carbon Brief, The world added a record amount of energy from renewable sources in 2016 and global coal use fell again, according to the 2017 BP Statistical Review of World Energy, published earlier this week. This helped to keep global CO2 emissions flat for the third year in a row, even as energy demand rose. The record 53 million tonnes of oil equivalent (Mtoe) added by non-hydro renewables met a third of the increase in global energy demand. Global coal use fell by 53Mtoe (1.4%) and is now 4% below the 2014 peak. Meanwhile, coal production fell by a record 231Mtoe (5.9%), as massive output declines continued in the US and China worked to reduce overcapacity and combat air pollution. Carbon Brief runs through BP’s new data and highlights some of the key changes in global energy production and use last year. Record renewables Non-hydro renewable energy sources, such as wind and solar, had a record year in 2016, adding 53Mtoe. They were the fastest-growing source of energy, up 14%, in line with average growth of 16% per year over the decade to 2015. Together with nuclear and hydro, low carbon energy supplied more than half of the net increase in global energy demand between 2015 and 2016. Read More here
