7 April 2017, New York Times, Rising Waters Threaten China’s Rising Cities. GUANGZHOU, China — The rains brought torrents, pouring into basements and malls, the water swiftly rising a foot and a half. The city of Dongguan, a manufacturing center here in the world’s most dynamic industrial region, was hit especially hard by the downpour in May 2014. More than 100 factories and shops were inundated. Water climbed knee-high in 20 minutes, wiping out inventory for dozens of businesses. Next door in Guangzhou, an ancient, mammoth port city of 13 million, helicopters and a fleet of 80 boats had to be sent to rescue trapped residents. Tens of thousands lost their homes, and 53 square miles of nearby farmland were ruined. The cost of repairs topped $100 million. Chen Rongbo, who lived in the city, saw the flood coming. He tried to scramble to safety on the second floor of his house, carrying his 6-year-old granddaughter. He slipped. The flood swept both of them away. Flooding has been a plague for centuries in southern China’s Pearl River Delta. So even the rains that May, the worst in the area in years, soon drifted from the headlines. People complained and made jokes on social media about wading through streets that had become canals and riding on half-submerged buses through lakes that used to be streets. But there was no official hand-wringing about what caused the floods or how climate change might bring more extreme storms and make the problems worse. A generation ago, this was mostly farmland. Three vital rivers leading to the South China Sea, along with a spider’s web of crisscrossing tributaries, made the low-lying delta a fertile plain, famous for rice. Guangzhou, formerly Canton, had more than a million people, but by the 1980s, China set out to transform the whole region, capitalizing on its proximity to water, the energy of its people, and the money and port infrastructure of neighboring Hong Kong.

7 April 2017, The Conversation, The stampede of wind farm complaints that never happened. National Wind Farm Commissioner, Andrew Dyer, has just released his much anticipated first annual report. In its first year of operation until the end of 2016, the National Wind Farm Commissioner says his office received: 46 complaints relating to nine operating wind farms (there were 76 operational wind farms in Australian in 2015)
- 42 complaints relating to 19 proposed wind farms
- two complaints that did not specify a wind farm.
The commissioner’s office closed 67 or these 90 complaints, with the remaining 23 complaints still in process. Of the 67 now-closed complaints, the office closed 31 because the complainant did not progress their complaint. This suggests these complaints were minor. The office closed the file on another 32 after it sent complainants more information about their complaints. This leaves only four, which the report describes two as being settled after negotiations between the parties, and two given the ambiguous category of “other”. These figures are frankly astonishing. The complaint investigating mechanism was set up after a Senate enquiry report that cost undisclosed millions to deal with a “massive” problem with wind turbines. But the hordes of people who apparently needed a way to help them resolve matters have now gone shy. Chair of the Senate Committee on Wind Turbines was ex-Senator John Madigan, a public critic of wind farms. Read More here
5 April 2017, ECOS, Before the storm. It’s a catastrophe in anyone’s book, not least those of insurance companies anticipating the tens of thousands of claims likely to be lodged.As the floods surged south in the days after Cyclone Debbie hit landfall near Bowen in north Queensland on March 28, a natural disaster was declared in five major centres in northern New South Wales.Citing the chairman of the Insurance Council of Australia, the Australian Financial Review said “in insurance terms, a catastrophe means a disaster that causes a significant number of claims in a region” and for Cyclone Debbie that could be claims over $1 billion. CSIRO’s Dr Chi-Hsiang Wang and colleagues have been researching the cost implications of extreme weather events but with a focus at the other end – predicting the likely cost before the storms. Counting the cost of extreme events Deloitte Access Economics last year delivered a report on building resilient infrastructure which estimated that, between 2002-03 and 2010-11, an annual average of more than $450 million was spent by Australian governments on restoring essential public infrastructure following extreme weather. If it’s business-as-usual, the report said, $17 billion is expected to be spent on direct replacement costs of essential infrastructure due to natural disasters between 2015 and 2050. These estimates don’t factor in the impacts of climate change. In the case of Cyclone Debbie, the wind intensity exceeded the limitations of the building specifications. “It’s not a surprise that we see considerable damage because the intensity is so high,” says Dr Wang. Until now, a cyclone with the force of Debbie was considered a once in a 2,000 year event by Australian design standard for wind actions (AS/NZS 1170.2:2011). That may change. “There’s a consensus among scientists, although not as strong as the consensus around rising global temperatures, that for some tropical cyclone basins around the world they are likely to see events of increased intensity,” he adds. What’s missing? Dr Wang says the current practice for wind impact assessment of physical infrastructure uses only wind intensity (in terms of wind gust) to gauge the damage potential of windstorms. “This ignores other threats brought upon by the accompanying rainfall and storm surge,” he says.

5 April 2017, Reuters, ANALYSIS-Trump declares end to “war on coal,” but utilities aren’t listening. Most U.S. power companies have no plans to alter their years-long shift away from coal. When President Donald Trump signed an executive order last week to sweep away Obama-era climate change regulations, he said it would end America’s “war on coal”, usher in a new era of energy production and put miners back to work. But the biggest consumers of U.S. coal – power generating companies – remain unconvinced. Reuters surveyed 32 utilities with operations in the 26 states that sued former President Barack Obama’s administration to block its Clean Power Plan, the main target of Trump’s executive order. The bulk of them have no plans to alter their multi-billion dollar, years-long shift away from coal, suggesting demand for the fuel will keep falling despite Trump’s efforts. The utilities gave many reasons, mainly economic: Natural gas – coal’s top competitor – is cheap and abundant; solar and wind power costs are falling; state environmental laws remain in place; and Trump’s regulatory rollback may not survive legal challenges. Meanwhile, big investors aligned with the global push to fight climate change – such as the Norwegian Sovereign Wealth Fund – have been pressuring U.S. utilities in which they own stakes to cut coal use. “I’m not going to build new coal plants in today’s environment,” said Ben Fowke, CEO of Xcel Energy, which operates in eight states and uses coal for about 36 percent of its electricity production. “And if I’m not going to build new ones, eventually there won’t be any.” Of the 32 utilities contacted by Reuters, 20 said Trump’s order would have no impact on their investment plans; five said they were reviewing the implications of the order; six gave no response. Just one said it would prolong the life of some of its older coal-fired power units. North Dakota’s Basin Electric Power Cooperative was the sole utility to identify an immediate positive impact of Trump’s order on the outlook for coal. “We’re in the situation where the executive order takes a lot of pressure off the decisions we had to make in the near term, such as whether to retrofit and retire older coal plants,” said Dale Niezwaag, a spokesman for Basin Electric. “But Trump can be a one-termer, so the reprieve out there is short.” Trump’s executive order triggered a review aimed at killing the Clean Power Plan. The Obama-era law would have required states, by 2030, to collectively cut carbon emissions from existing power plants by 30 percent from 2005 levels. It was designed as a primary strategy in U.S. efforts to fight global climate change. The U.S. coal industry, without increases in domestic demand, would need to rely on export markets for growth. Shipments of U.S. metallurgical coal, used in the production of steel, have recently shown up in China following a two-year hiatus – in part to offset banned shipments from North Korea and temporary delays from cyclone-hit Australian producers.RETIRING AND RETROFITTING Coal had been the primary fuel source for U.S. power plants for the last century, but its use has fallen more than a third since 2008 after advancements in drilling technology unlocked new reserves of natural gas. Hundreds of aging coal-fired power plants have been retired or retrofitted. Huge coal mining companies like Peabody Energy Corp and Arch Coal fell into bankruptcy, and production last year hit its lowest point since 1978. Read More here
