17 May 2017, Yale Climate Connections, Sea-level rise, but no mention of ‘climate change’. A film maker documents sea-level rise risks facing Virginia’s Hampton Roads region, and avoids the baggage of the terms ‘climate change’ or ‘global warming.’ In Hampton Roads, a moniker for both a massive natural harbor in southeast Virginia and a metropolitan region comprising 17 small cities and municipalities, tidal flooding is as common as Chesapeake Bay blue crabs. Oh yes. Lest one forget, Hampton Roads is also home to the world’s largest Naval base. Low-lying roads flood so often that drivers use depth markers positioned on highway shoulders to gauge whether they’ll be able to pass through. Why is this happening? Sea level rise. And why are the seas rising? Well, let’s not talk about that. Shortsighted!, you might say. Or worse. But to film director Roger Sorkin, talking about sea-level rise – and more importantly, how to adapt to it and build more resilient, forward-thinking communities – without talking about climate change is a well-considered strategy. Avoiding buzz words that may turn people off For the record, Sorkin is no climate change contrarian. He acknowledges that carbon emissions are responsible for sea-level rise. And that we humans are responsible. But he also believes in meeting folks where they are. That’s why, he explains, his audiences do not hear the words “climate change,” “global warming,” or “carbon” in “Tidewater,” his documentary film about sea-level rise in Hampton Roads. “Stories matter to us,” Sorkin says. “And the building blocks are the words that you use to tell stories. Certain words press peoples’ buttons and produce visceral reactions.” Sorkin hopes to use “Tidewater” as a way of engaging conservative coastal communities and Republican lawmakers in swing states. His hope is that the film’s apolitical tack will appeal to viewers who tend to associate all things related to climate change with liberalism. “It’s really intended to nationalize the story of Hampton Roads as a real national security concern,” he says.

18 May 2017, New York Times Antarctic Dispatches: Miles of Ice Collapsing Into the Sea. The acceleration is making some scientists fear that Antarctica’s ice sheet may have entered the early stages of an unstoppable disintegration. Because the collapse of vulnerable parts of the ice sheet could raise the sea level dramatically, the continued existence of the world’s great coastal cities — Miami, New York, Shanghai and many more — is tied to Antarctica’s fate. Four New York Times journalists joined a Columbia University team in Antarctica late last year to fly across the world’s largest chunk of floating ice in an American military cargo plane loaded with the latest scientific gear. Inside the cargo hold, an engineer with a shock of white hair directed younger scientists as they threw switches. Gravity meters jumped to life. Radar pulses and laser beams fired toward the ice below. On computer screens inside the plane, in ghostly traces of data, the broad white surface of the Ross Ice Shelf began to yield the secrets hiding beneath. Read More here
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, 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
