Example Input: 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.
Example Output: 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.

Example Input: Paragraph: "As he asked Philadelphia City Council to consider a $300 million investment in the city’s parks and recreation centers, Mayor Jim Kenney told a success story. During his budget address in council chambers last week, the first-year mayor said that when the city and the Fairmount Park Conservancy invested $5 million in Hunting Park, ""crime went down 89 percent within a half mile radius of the park over the next three years."" That seemed like a huge drop in a high-crime area of the city, so we decided to check out the claim. The Kenney administration said it got the statistic from a Dickinson College study conducted in conjunction with Philadelphia Police and the Fairmount Park Conservancy, a nonprofit that leads capital projects and programming across 10,200 acres of Fairmount Park and 100 neighborhood parks throughout the city. Meg Holscher, the Conservancy’s senior director of development, said the 87-acre Hunting Park in North Philadelphia was identified in 2008 as an area of development because of how close it was to a high number of families. At the time, prostitution and drug trade were common in and around the park. After community meetings and input from neighbors, the Conservancy -- along with the Philadelphia Department of Parks and Recreation -- presented a master plan for the park in October 2009 that outlined two new playgrounds, a community garden and farmers market, new tennis courts and youth tennis programming, as well as a renovated football and soccer field. One of the most visible changes, though, was 64 lights placed around the park, which Holscher said residents wanted to curb illegal activity and violence. ""This project for us was a little bit of a game changer,"" she said. ""We’ve started to look at parks and how they are tied to healthy eating, healthy living and violence prevention."" Holscher said the $4.5 million Hunting Park capital projects and programming was funded through both public and private funds. In addition to that, another $500,000 was added through grants and corporate donations, bringing the total amount for phase one of the revitalization to some $5 million. After efforts to spruce up the park started in 2010, Conservancy staff started hearing from community members that it seemed like crime in the area had slowed, but an analysis wasn’t completed until 2014. That year, Amanda Vandenburg, then a researcher at Dickinson College in Carlisle, was interested in how parks influence communities. Vandenburg said she analyzed public data from the Philadelphia Police Department and charted crime statistics from 2006, before the revitalization efforts began, through 2013, when the first phase of the project had wrapped up. The data included both part I crimes (violent crimes like homicide, rape and aggravated assault) and part II crimes (like simple assault, prostitution, drug possession and other non-violent offenses.) She mapped instances of crime from inside and a half-mile buffer around the park, and found that there was a spike in crime between 2006 and 2007. After that point, crime began decreasing in 2008 citywide as police enforcement efforts in Philadelphia changed under a new mayoral administration. But crime continued to go down near Hunting Park. Between 2009 and 2013, ""there was an 89 percent drop in the number of crimes,"" according to Vandenburg’s study. Rape and theft from vehicle crime incidents increased over that time period, but other crimes decreased, including prostitution and drug use. Vandenburg also conducted a ""hot spot"" analysis that showed areas predicted to have the highest amounts of crime were closer to and in the park in 2009 and moved away from the park by 2013. While she said the revitalization of Hunting Park can’t be attributed as the only reason for a decrease in crime in the immediate area, the data does support the theory that illegal activity in the area decreased as the park was improved. Our Ruling Kenney used the efforts in Hunting Park as an example of why City Council should authorize more funds to revitalize parks and recreation centers throughout the city. He said ""when the city and the Fairmount Park Conservancy invested $5 million in Hunting Park, crime went down 89 percent within a half mile radius of the park over the next three years."" The Fairmount Park Conservancy confirmed that it -- along with the city and private donors -- invested about $5 million in revitalizing the park. Vandenburg, who conducted the study, said crime did in fact drop by 89 percent within a half-mile radius over the next three years. We rule the claim ." Claim: When the City and the Fairmount Park Conservancy invested $5 million in Hunting Park, crime went down 89 percent within a half mile radius of the park over the next three years.

Example Input: Paragraph: Tim Thornhill, a transplanted Texan who formed the Mendocino Wine Company six years ago in the county north of San Francisco, is one of them. Along with his brother, Tom, and former Fetzer Vineyards winemaker Paul Dolan he bought the Parducci Wine Cellars and revived the wine’s reputation. He also used his background in horticulture to design a wetland area in the middle of the vineyard to reclaim wastewater, which is a byproduct of wine making. “What I run into constantly are people who say ‘I wish I could be environmental, but I can’t afford to be,’” he said. “And it is always clear to me that they haven’t figured out that being environmental is being efficient. And when you’re efficient, money drops to the bottom line.”   Water is a concern in California, where there is always a shortage. Wineries can produce hundreds of thousands of gallons of wastewater, mostly from the grape-crush, tank and barrel cleaning and bottling operations. Wastewater contains the grapes’ natural sugars that deplete the water’s oxygen. Thornhill designed a system of gravity-fed tanks and trickle towers made from old wooden slats that oxygenate the water. The result is a small wetlands area and a pond that ducklings seem to favor. “When you start seeing life, you know your water is getting clean and you look in here between the beautiful green filaments of algae, the duckweed, the rushes, the insects, the birds we’re seeing. We’ve got life,” he explained. The water will be used for drip irrigation in the vineyards, to hose down redwood tanks where the wine ages slowly in large lots and it will be reclaimed to start the cycle all over. Unlike Thornhill’s vineyards, Chiarito Vineyards uses natural rainfall and runoff for its much smaller production. “This is dry farmed. There is no drip irrigation. There’s no nothing. They are totally dependent on the spring rains and the runoff from the mountains,” John Chiarito said. As a result, the vines send their roots down into the volcanic ash that lies under a topsoil of river deposits and sandstone. With a yield of less than three tons of grapes per acre, Chiarito estimated he makes about 800 cases of Zinfandel and Nero d’Avola. It all started 20 years ago when he bought an abandoned walnut orchard and planted Zinfandel vines in “the old style, eight by eight foot spacing, head-trained. No wires.”   Chiarito farms organically, but his wine is not certified because he said it involves too much paperwork. Last week the U.S. Alcohol and Tobacco Tax and Trade Bureau and the Department of Agriculture issued new rules to clarify what wineries must do to use the word organic on their labels. The same week the European Commission withdrew its proposal to have a wine classified as organic, saying it was unwilling to compromise on organic standards. In addition to wine, Chiarito also makes his own prosciutto. “I’ve been making prosciutto for about 25 years. I guess I’m a bit of a throw back,” he said, which may explain his passion for doing everything by hand. Claim: Green is the new organic in wines.
Example Output:
It’s easy being green in Mendocino, California, where many of the county’s 84 vintners are certified organic, biodynamic or carbon neutral.
