"Louisiana, the most common way to visualize the state’s existential crisis is through the metaphor of football fields. The formulation, repeated in nearly every local newspaper article about the subject, goes like this: Each hour, Louisiana loses about a football field’s worth of land. Each day, the state loses nearly the accumulated acreage of every football stadium in the N.F.L. Were this rate of land loss applied to New York, Central Park would disappear in a month. Manhattan would vanish within a year and a half. The last of Brooklyn would dissolve four years later. New Yorkers would notice this kind of land loss. The world would notice this kind of land loss. But the hemorrhaging of Louisiana’s coastal wetlands has gone largely unremarked upon beyond state borders. This is surprising, because the wetlands, apart from their unique ecological significance and astounding beauty, buffer the impact of hurricanes that threaten not just New Orleans but also the port of South Louisiana, the nation’s largest; just under 10 percent of the country’s oil reserves; a quarter of its natural-gas supply; a fifth of its oil-refining capacity; and the gateway to its internal waterway system. The attenuation of Louisiana, like any environmental disaster carried beyond a certain point, is a national-security threat.
Where does it go, this vanishing land? It sinks into the sea. The Gulf of Mexico is encroaching northward, while the marshes are deteriorating from within, starved by a lack of river sediment and poisoned by seawater. Since 2011, the National Oceanic and Atmospheric Administration has delisted more than 30 place names from Plaquemines Parish alone. English Bay, Bay Jacquin, Cyprien Bay, Skipjack Bay and Bay Crapaud have merged like soap bubbles into a single amorphous body of water. The lowest section of the Mississippi River Delta looks like a maple leaf that has been devoured down to its veins by insects. The sea is rising along the southeast coast of Louisiana faster than it is anywhere else in the world.”

35,000 walrus gather on the shoreline near Point Lay, Alaska.
"The plight of thousands of walruses forced to crowd on to an Alaska beach because of disappearing sea ice has set off an all-out response from the US government to avoid a catastrophic stampede. The FAA has re-routed flights, and local communities have called on bush pilots to keep their distance in an effort to avoid setting off a panic that could see scores of walruses trampled to death."
"The extraordinary sighting – the biggest known exodus of walruses to dry land ever observed in the Arctic under US control – arrived as the summer sea ice fell to its sixth lowest in the satellite record last month.
“Those animals have essentially run out of offshore sea ice, and have no other choice but to come ashore,” said Chadwick Jay, a research ecologist in Alaska with the US Geological Survey.”
US reroutes flights to avoid walrus stampede
"OVER the next two weeks, hundreds of millions of people will watch Americans like Ted Ligety and Mikaela Shiffrin ski for gold on the downhill alpine course. Television crews will pan across epic vistas of the rugged Caucasus Mountains, draped with brilliant white ski slopes. What viewers might not see is the 16 million cubic feet of snow that was stored under insulated blankets last year to make sure those slopes remained white, or the hundreds of snow-making guns that have been running around the clock to keep them that way.
Officials canceled two Olympic test events last February in Sochi after several days of temperatures above 60 degrees Fahrenheit and a lack of snowfall had left ski trails bare and brown in spots. That situation led the climatologist Daniel Scott, a professor of global change and tourism at the University of Waterloo in Ontario, to analyze potential venues for future Winter Games. His thought was that with a rise in the average global temperature of more than 7 degrees Fahrenheit possible by 2100, there might not be that many snowy regions left in which to hold the Games. He concluded that of the 19 cities that have hosted the Winter Olympics, as few as 10 might be cold enough by midcentury to host them again. By 2100, that number shrinks to 6.
The planet has warmed 1.4 degrees Fahrenheit since the 1800s, and as a result, snow is melting. In the last 47 years, a million square miles of spring snow cover has disappeared from the Northern Hemisphere. Europe has lost half of its Alpine glacial ice since the 1850s, and if climate change is not reined in, two-thirds of European ski resorts will be likely to close by 2100.
The same could happen in the United States, where in the Northeast, more than half of the 103 ski resorts may no longer be viable in 30 years because of warmer winters. As far for the Western part of the country, it will lose an estimated 25 to 100 percent of its snowpack by 2100 if greenhouse gas emissions are not curtailed — reducing the snowpack in Park City, Utah, to zero and relegating skiing to the top quarter of Ajax Mountain in Aspen. …
The ski season in parts of British Columbia is four to five weeks shorter than it was 50 years ago, and in eastern Canada, the season is predicted to drop to less than two months by midcentury. At Lake Tahoe, spring now arrives two and a half weeks earlier, and some computer models predict that the Pacific Northwest will receive 40 to 70 percent less snow by 2050. If greenhouse gas emissions continue to rise — they grew 41 percent between 1990 and 2008 — then snowfall, winter and skiing will no longer exist as we know them by the end of the century.”

“Smith Island is the last inhabited island in Maryland, a place where residents, hearty watermen who make their living catching oysters and blue crabs, still speak in the Cornish dialect of their ancestors. Many Smith Islanders can trace their ancestry back 12 generations to the English colonists who settled here in the 17th century. And yet their link to this land may soon be broken: Smith Island is eroding. Though scientists differ on how long it will be before the island is underwater, anywhere between 30 and 100 years, there is no dispute about the cause: rising seas. The global trend of rising ocean levels is especially acute in the Chesapeake Bay, where water is rising at twice the world average. To make matters worse, the land around the Chesapeake is sinking: a trend scientists call post-glacial subsidence. According to a state-commissioned task force, Maryland is now losing 260 acres of tidal shoreline annually.”
