10 May 2017, Climate Central (report), Coastal communities are enduring growing flood risks from rising seas, with places like Atlantic City, sandwiched between a bay and the ocean, facing some of the greatest threats. Guided by new research by Climate Central’s Scott Kulp and Benjamin Strauss, reporter John Upton and photographer Ted Blanco chronicled the plight of this city’s residents as they struggle to deal with the impacts. Upton spent months investigating how the city is adapting, revealing vast inequity between the rich and the poor…. DeDomenicis has lived in this house since 1982, a few hundred feet from a bay. She used to work as a restaurant server; now she’s a school crossing guard. Her husband walked a mile to his job at Bally’s Casino until he retired in January. They’ve seen floods worsen as the seas have risen, as the land beneath them has sunk, and as local infrastructure has rotted away. “It comes in the front door, the back door, and then from the bottom of the house, in through the sides,” DeDomenicis said. “You watch it come in and it meets in the middle of the house — and there’s nothing you can do.” Two miles east of Arizona Avenue, the U.S. Army Corps of Engineers is spending tens of millions of dollars building a seawall to reduce storm surge and flooding risks for Atlantic City’s downtown and its towering casinos, five of which have closed in the past four years. A few miles in the other direction, it’s preparing to spend tens of millions more on sand dunes to protect million-dollar oceanfront homes. Read More here

10 May 2017, Renew Economy, Turnbull abandons fig leaf and stands naked on climate policy. You would think that with all the hoo-ha about the scandalous increases in electricity prices that it would have rated some sort of mention in the budget. You know, one of the biggest cost inputs for business being addressed in the government’s economic centrepiece. But no. The 2nd Morrison/Turnbull fiscal document blithely ignores the issue, despite the fact that their lack of policy direction in the last few years has been the major contributor to the price surges that are scorching household and business budgets. There’s some pointless extra money for coal seam gas, the removal of some funds for carbon capture (finally) and some previously promised funds for solar thermal (about time), and even another thought bubble on Snowy Hydro – this time to buy it out from the state governments. See Matt Rose’s article for more details. But there is nothing on climate change, no grand vision on energy. There are no new funds for the Direct Action policy that Turnbull had once ridiculed as a fig leaf for a climate action, and nothing on what might take Australia along the path to the pledge it signed in the Paris deal – effectively to reach zero net emissions by 2050. As Labor’s Mark Butler noted this morning, the Coalition’s climate change policy has officially gone from that fig-leaf to a non-existent farce. Nearly three years after celebrating the dumping the carbon price (above), slashing the RET and ignoring expert advice (CCA and the Climate Council), the Coalition government has no actual policy, on energy or climate, and its negligence is adding to the stunning rise in electricity prices it is trying to blame on everything and everyone else. “Malcolm Turnbull, the Prime Minister who once said he didn’t want to lead a Liberal Party that didn’t feel as strongly about climate change as he did, is now the Prime Minister who has completely dropped any pretence of attempting to combat climate change,” Butler says in his statement, noting that climate change did not rate a single mention in the Budget speech. “As the central pillar of the Direct Action policy, the Emission Reduction Fund, runs out of funds, this budget delivers ZERO new policies or funding to drive down pollution and combat climate change. This budget allocates more new money to the Department of the House of Representatives than it does to tackling climate change. “Budgets are about choices and priorities, and this budget makes it perfectly clear the Turnbull government isn’t choosing a safe climate because they don’t think it is a priority. This budget finally makes official what we already know; this Liberal government is failing all future generations of Australians.” Read More here
10 May 2017, Climate News Network, Ocean oxygen decline greater than predicted. Circulation changes caused by warming waters and melting polar ice are the most probable explanations for the rapidly falling levels of oxygen in the ocean. US scientists who have been warning that warmer oceans are more likely to be poorer in dissolved oxygen have now sounded the alarm: ocean oxygen levels are indeed falling, and seemingly falling faster than the corresponding rise in water temperature. That colder water can hold more dissolved gas than warmer water is a commonplace of physics: it is one reason why polar seas are teeming with marine life and tropical oceans are blue, clear and often relatively impoverished. In 2013, an international consortium of marine scientists warned that oxygen levels in the oceans could fall by between 1% and 7% by the century’s end. And this could, other scientists predicted, lead to what they politely called “respiratory stress” for some marine life. Ocean warming Ocean ecologists in the US and Germany warned last year that parts of the deep oceans were already showing signs of oxygen deprivation with corresponding dead zones. Earlier this year, another research group looked at the computer simulations for the years 1920 to 2100 and predicted that the hazards were likely to increasewith warming. Now the team have returned to the issue. They report in Geophysical Research Letters that they looked at data for the last 50 years and found the oxygen levels started dropping in the 1980s, as ocean temperatures began to climb – and falling unexpectedly rapidly. The trend of oxygen falling is about two to three times faster than what we predicted from the decrease of solubility associated with ocean warming,” says Takamitsu Ito, of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, who led the study. “This is most likely due to the changes in ocean circulation and mixing associated with the heating of the near-surface waters and the melting of polar ice.” Read More here
6 May 2017, Inside Climate News, Extreme Weather Flooding the Midwest Looks a Lot Like Climate Change. Devastating storms still roiling much of the American Midwest have dumped record levels of rain over the past week and caused flash flooding that has killed at least 10 people, inundated towns and highways, and forced hundreds of people to evacuate their homes. Parts of Missouri, Illinois, Indiana, Arkansas and Louisiana received 10 to 15 inches of rain in the past seven days, according to the National Weather Service, resulting in record crests of numerous rivers across the central United States.Extreme storms like these have become more common as global temperatures have risen and the oceans have warmed. Some have the clear fingerprints of man-made climate change. “Of course there is a climate change connection, because the oceans and sea surface temperatures are higher now because of climate change, and in general that adds 5 to 10 percent to the precipitation,” Kevin Trenberth, a climate scientist with the National Center for Atmospheric Research, said. “There have been many so-called 500-year floods along the Mississippi about every five to 10 years since 1993.” Scientists won’t know the extent to which climate change played a role in these storms unless they do an attribution study. Such analyses determine how much the rise in trapped greenhouse gases increased the odds of a single event happening. Increasingly, scientists have tried to do these studies far more quickly to spread accurate information about how climate change is affecting us today and improve longer-term forecasts and warnings. An attribution study of last August’s deadly Louisiana’s storms—classified as a 1,000-year storm in the worst-hit areas and a 500-year storm in others—found that human-caused climate warming increased the chances of the torrential rains by at least 40 percent. That figure corresponds to the overall increase in extreme storms in the region. “Across the board, the United States has seen an increase in the heaviest rainfall events, and the Midwest specifically has seen an increase [in these events] of almost 40 percent,” said Heidi Cullen, chief scientist at Climate Central and a member of World Weather Attribution (WWA), a group that is developing methods to quickly determine climate change’s role in extreme weather events.
