PROBLEM: Paragraph: With global warming widely expected to slash snowfall, especially at lower levels, the Swiss tourism industry is looking for ways to preserve a lucrative business brutally exposed to the weather. Enter Napa, Serbia’s last circus bear. The Arosa ski resort in eastern Switzerland has created a $6.5 million refuge hosting Napa and two other bears rescued from cages at restaurants in Albania to help draw summer visitors and reduce its reliance on skiers and snowboarders. School classes, families and a group of army veterans celebrating an 80th birthday were visiting one recent summer day, helping the park toward what Arosa tourism director Pascal Jenny said was a target of 50,000 visitors this year. Arosa has reinvented itself before - moving to winter tourism in the 1930s after decades as a health resort for tuberculosis patients. But with nearly 620,000 overnight stays in winter last year, more than three times the summer total — it will not be easy. Jenny, who fears a sharp decline in snowfall over the next 20 or 30 years, is hedging his bets. “What gives us some hope is that artificial snow is making strong technical advances. I can make snow now at 5 degrees above freezing,” he said, standing on an observation platform beside the Weisshorn cable car which gives a sweeping view of the snow-capped Alpine valley. His two-pronged approach highlights the dilemma faced by mountain resorts — how to retain profits as they embark on what the Organisation for Economic Co-Operation and Development (OECD) says needs to be a global rethink of tourism. “The consequences of climate change will be felt across the travel and tourism sector over the coming decades,” the OECD, whose member countries represent 80% of the world’s trade and investment, said in a 2018 study of megatrends in tourism. Storms, flooding and tidal surges will threaten coastal regions, southern destinations face extreme heatwaves and northern ones will see shorter periods of snowfall, it said. Mountain resorts tend to be higher in Switzerland than in Austria or France, giving them better chances as snow becomes scarcer. But even at 3,000 meters, pistes could see snow depths more than halved by 2100 if greenhouse gas emissions are not curbed, a report in The Cryosphere, a peer-reviewed geosciences journal named after the frozen water parts of the Earth, said. Resorts below 1,200 meters - as about a quarter of Alpine ones are - might get almost no snow, said the 2017 report, whose title starts “How much can we save?”. Snow levels will gradually stabilize if global temperature rises are contained, it says. Arosa is 1,775 meters up but Jenny worries that a loss of snow in the lowlands will cost it visitors because people will lose their emotional connection with snow. “That is almost more dangerous for the sector,” he said. Hence his interest in an industrial estate in Denmark, where Arosa is cooperating on a project to make artificial snow so that urban dwellers can learn to ski and then, he hopes, go on to hone their skills in the Alps. The economics are clear: a daily lift pass for skiers in Arosa costs 79 Swiss francs ($80.27), while a summer hiker or mountain biker typically pays 18 francs for a pass that lets them use a rope park, a swimming area and paddle boats on the town’s lake. Hotels and restaurants charge more in winter too, but the strong Swiss franc has priced many people out. Switzerland is one of the wealthiest countries in the world, and the Swiss government says the long-term outlook for tourism is healthy. “Mountain summers can position themselves as an alternative to the Mediterranean regions,” a 2017 report said. Summer tourism already accounts for 60% of overnight stays across Switzerland, but the season brings in only 18% of revenue, said Therese Lehmann, an economist at the University of Bern’s Centre for Regional Development. Government data already shows a 24% drop in skiers in the decade to 2016, with other factors as well as climate change. “The decline of ski tourism — a powerful economic engine — will have more of an impact than the additional revenue in summer,” said Dominik Siegrist, director of the Institute for Landscape and Open Space at Switzerland’s University of Applied Sciences Rapperswil. Europe’s population is aging and younger people are less interested in skiing. Snowshoeing, winter hiking, sledding and ski touring — in which people hike up mountains, are on the increase, industry lobby Swiss Tourism says. Consolidation of winter tourism is on the horizon, with overnight stays in bigger Swiss resorts up 1 percent in the decade to 2015, but down 17 percent in smaller ones. “Lots of smaller ones are grasping at straws, trying to survive as long as they can because the valleys depend on this tourism,” Siegrist said. Large resorts in the Swiss cantons of the Grisons and Valais, Austria’s Tyrol province and France’s Savoie region have the marketing pull to survive, Siegrist said, listing high- altitude Andermatt, Zermatt and St Moritz in Switzerland. The Andermatt Swiss Alps resort, in central Switzerland, is targeting cyclists in summer, and has also built new lifts to lure winter sports fans. It covers a nearby glacier with strips of artificial fleece in spring to help reduce melting and creates piles of snow higher than houses to deploy on ski pistes as early as November to avoid having to use expensive artificial snow. The strong Swiss franc has hit ski lifts focused on winter business from European visitors hard in the past 10 years, the government says, but the minority of lifts with strong summer business are booming thanks to visitors from overseas. Many smaller lift firms get cheap loans and, increasingly, state subsidies to help balance the books, said Lehmann. Roughly a third are debt-free, but depend on long-haul tourism, which she said was not ideal from an environmental point of view, because flights are a major contributor to holiday carbon emissions. “Maybe we have to get away from focusing solely on growth, and promote Alpine areas as good habitats for living, not just for tourism,” she said. Listed cable car companies Bergbahnen Engelberg Truebsee Titlis Bet AG (TIBN.S) and Jungfraubahn Holding AG (JFN.S), cite year-round visitors from Asia - especially China and India - as important sources of income. Asked about sustainability, Titlis marketing director Peter Reinle said the firm’s prospects were good for the next 50 years. “We as a single entity can not solve the whole climate problem. Politicians have to provide framework conditions.”  Jungfraubahn’s Corporate Secretary Christoph Schlaeppi said it employed 800 local people, helping to make life in the mountains economically sustainable for a new generation. The government says it is up to individual resorts to decide how much they want to attract Asian groups, but focuses its own promotion efforts on individual travelers and sustainability, noting Japanese tourists now come independently and stay longer. “We have to see that guests from Asia making the long flight to Europe or Switzerland stay as long as possible,” Richard Kaempf, head of tourism policy at the State Secretariat of Economic Affairs, told Reuters. While the government encourages year-round use of mountain infrastructure, he said it is not giving up on winter sports, a deep cultural touchstone for the Swiss. But he acknowledged the growing challenge of lowlanders losing the “winter feeling”. Claim: High and dry: Alpine resorts grapple with climate change.

SOLUTION: The prospect of searing heatwaves driving holidaymakers to cool mountains and children asking grandparents about their memories of snow is focusing minds in Alpine ski resorts on the implications of climate change.

PROBLEM: Paragraph: "One theme Sen. Bernie Sanders has repeatedly touched on during his run for the Democratic nomination for president has been the high cost of prescription drugs. His comment during the Feb. 11 Democratic debate at the University of Wisconsin-Milwaukee was typical as he rattled off a list of problems with the U.S. health care system: ""In America, we pay, by far, the highest prices in the world for prescription drugs."" We asked the Sanders campaign for the source of his claim. We didn't get a response. So we searched on our own. One organization that tracks such things is the International Federation of Health Plans, based in London. Their latest price report, from 2013, lists eight common drugs. Compared with England, the Netherlands, Spain, Switzerland and Canada, U.S. prices were far higher, sometimes dramatically so. Consider Nexium, the medicine widely used to treat acid reflux. A prescription that would cost $60 or less in other countries costs, on average, $215 in the United States. And that's just the average. Prices vary widely in this country: In 5 percent of the cases, the cost was $395. ""What Bernie says is true. There's nowhere that pays the same price as America,"" said Tom Sackville, the federation's CEO. In addition, ""there is this huge variation in price across America. Anything above the average is quite unjustified. When you get up to the 95th percentile, you're talking grand robbery."" The findings were similar in an April 2013 study published in the journal Health Affairs, which looked at the prices of brand name drugs in the United States, United Kingdom, Switzerland, Germany, France, Canada and Australia. In each of the three years studied -- 2005, 2007 and 2010 -- U.S. prices were consistently higher. The one exception: Switzerland. In addition, researchers found that, between 2005 and 2010, ""the gap between the United States and other countries seemed to widen."" And it wasn't just new drugs being embraced first in the United States that was driving up costs. They concluded that ""prices for older products rose faster in the United States than in other countries."" But Joel Farley of the University of North Carolina at Chapel Hill's Eshelman School of Pharmacy cautioned that the rule doesn't always apply to generic drugs. A 2008 comparison of 19 generic drugs found that some U.S. prices were lower than Canadian prices. ""In some cases it has to do with availability,"" he said. In other cases, a country may set the drug price low and in that fixed-price market ""there's no incentive to go lower."" The Wall Street Journal published an analysis in December that concluded 98 percent of 40 top branded drugs were more expensive in the United States than in England. In Norway, 93 percent of the 40 top branded drugs cost less than in the United States. And in Ontario, a comparison of 30 drugs showed that U.S. prices were also higher for 93 percent of the products. Why are the brand name prices so much lower in other countries, and why is there so much variation in the United States? Big customers can negotiate big discounts. So the countries with socialized medicine have a lot of leverage at the negotiating table, the experts told us. In the United States, hospitals, wholesalers and insurance companies all do their own negotiations. The Veterans Administration can -- and does -- negotiate dramatically lower prices. Under Medicaid, the drug companies are required to provide their medicines at a price that's as low as it is for any of their regular customers. But Medicare has been prohibited by law from negotiating lower prices since 2006, and that's a huge chunk of the U.S. health care industry. (When Barack Obama was first running for president, he promised to repeal that Bush-era restriction, but then backed off in an attempt to get passage of the Affordable Care Act.) The pharmaceutical industry says it needs the extra income to pay for research to keep new, desperately needed drugs coming. But with everyone getting a bargain, Americans are financing that research for the rest of the world, experts told us. Yet there's another way to look at the issue, said Amitava Dasgupta, a clinical toxicologist at the University of Texas Health Science Center at Houston. The tablet that costs a dollar in the United States may only cost 20 cents in India, but that drug is far more expensive to the average person in India because their income is so much lower. ""The U.S. subsidizes research for the world,"" he said. ""But I would look at that as philanthropy."" Our ruling Sanders said, ""In America, we pay, by far, the highest prices in the world for prescription drugs."" When it comes to brand-name drugs, which yield the highest profit for the pharmaceutical industry, studies support Sanders' claim -- although not always on a drug-by-drug basis. In addition, the differences in price can be dramatic because the U.S. health care system is so splintered, and Medicare is prohibited by law from using its market share to bargain for lower prices. We found one study comparing the United States and Canada that found exceptions for generic drugs, where the profit margin is much lower and which make up a much smaller share of prescription drug spending. But on balance," Claim: In America, we pay, by far, the highest prices in the world for prescription drugs.

PROBLEM: Paragraph: Activists in Arkansas accused Republican Sen. Tom Cotton of sending constituents “cease-and-desist” letters. But while it’s true that at least one member of the group received one, it is unclear how many constituents at large have as well. A spokesperson for Cotton’s office, Caroline Rabbitt Tabler, confirmed the existence of the letters, saying that they were issued “under extreme circumstances.” She also said that it was rare to send any constituent such a letter. There has been no confirmed tally of how many times it has happened. The letters began getting attention when the liberal group Ozark Indivisible posted a picture of one on Twitter on 17 January 2018, along with a message taunting the senator: #TraitorTommy @TomCottonAR scared of his constituents calling so he’s sending out cease and desist letters. You’re too [chicken] to lead CIA if you can’t even listen to constituents! #arpx #TraitorTommy @TomCottonAR scared of his constituents calling so he’s sending out cease and desist letters. You’re too 🐔 to lead CIA if you can’t even listen to constituents! #arpx pic.twitter.com/N1HAGCmbW6 — Ozark Indivisible (@OZRKIndivisible) January 18, 2018  The letter stated: This letter is immediate notification that all communication must cease and desist immediately with all offices of US Senator Tom Cotton. All other contact will be deemed harassment and will be reported to the United States Capitol Police. The letters themselves, however, are not recent; the one posted by Ozark Indivisible was dated 17 October 2017. A Fayetteville resident, Stacey Lane, identified herself as the recipient of the letter posted online. Rabbitt Tabler said Cotton’s office did not accuse her of saying anything threatening but did not go into detail on why it sent her the letter. Ozark Indivisible confirmed to us on 19 January 2018 that Lane is a member of their organization. They also disputed reports that Lane threatened anyone or called a staffer a “cunt.” The group added: There have been others who have received the letters, but they do not want to come forward. They are not OI members. According to reports, “an unspecified number of individuals” received letters that month. Rabbitt Tabler said in a statement that they are “only used under extreme circumstances”: Senator Cotton is always happy to hear from Arkansans and encourages everyone to contact his offices to express their thoughts, concerns, and opinions. In order to maintain a safe work environment, if an employee of Senator Cotton receives repeated communications that are harassing and vulgar, or any communication that contains a threat, our policy is to notify the U.S. Capitol Police’s Threat Assessment Section and, in accordance with their guidance, send a cease and desist letter to the individual making the harassing or threatening communication. Another person, who did not identify themselves, told the Arkansas Times that they received a similar letter. They said: I believe if Tom Cotton’s office were to respond as to why they sent this letter, I think they just honestly don’t want to listen to any citizen’s opposing view or hear the numerous grave concerns U.S. citizens have about the serious & ongoing attack on our Democracy and past election cycle in which a foreign, hostile Russian government interfered, they don’t want U.S. citizens to call and speak their mind and truth in a very direct manner and they obviously don’t want to be held accountable for their words and actions while serving all the people in this nation. I may have used unprofessional and unbecoming language at times as the anxiety and stress of what I’m witnessing is at times too great a burden to control and I have vehemently expressed my righteous anger at Senator Cotton’s complicitness with this harmful regime. Cotton, whose current term in office runs through 2020, has come under criticism from his constituents in the past. During February and April 2017 town hall events, he was pelted with questions regarding various issues and hit with chants that included, “Do your job.” Claim: "Sen. Tom Cotton's office has sent ""cease-and-desist"" letters to constituents ordering them not to contact him."

SOLUTION:
We contacted Cotton’s office seeking further comment on the October 2017 letters and explore any connection to the town halls, but did not receive response.
