DENVER, Colorado — Cloud seeding can provide between 5% and 15% more snow to help ski areas, farmers and watersheds in the state, supporters say. "These observations show us that cloud seeding does work," said University of Colorado researcher Katja Friedrich, who has studied cloud seeding inside and outside of a laboratory. She worked with scientists who flew planes near moisture-rich clouds and injected them with silver iodide, a substance that causes moisture to become heavy and fall to the ground as snow. On a radar image, she pointed outlines of snow that later formed. The visible lines matched the pattern the cloud seeding plane had flown in the sky. Cloud seeding in Colorado aims to produce more snow, not rain. Friedrich said it's difficult to quantify how much additional snow is created. Cloud seeding doesn't make more clouds, but supporters believe it gets more snow out of an approaching storm. Planes can be used to seed approaching storm clouds. Ground seeders use propane to heat the air and also used in the mountains and Western Slope. Silver iodide is then added to the warmed air as it rises. The moisture, already in the clouds, bonds to the silver iodide. When it becomes heavy, it falls to the ground as snow. Cloud seeding has been happening for about 70 years in Colorado but is slowed in years when there is heavy snowfall. Cloud seeders operated during the 2018-2019 winter but slowed in places where significant snowpack accumulated. A man who owns a cloud seeding company on the Western Slope said the technology works well. Cloud seeder's viewpoint Cloud seeders dot highpoints in Colorado from the west to central part of the state. Ski areas hire Eric Hjermstad's Western Weather Consultants company to cloud seed early in the season, so there's more natural snow before opening day. He continues seeding until mid-April. He showed off a cloud seeder located at a recreation site north of Leadville. He can remote start the seeder, turn on the propane flame and add the silver iodide. 2040

As the U.S. enters into colder weather, masks meant to prevent the spread of COVID-19 won't be the only face coverings one sees out on the street.It's led many to wonder: Is a mask necessary if I'm already wearing a scarf over my nose and mouth?Health experts say: Not so fast. Doctors say the best masks to wear during the winter are the same you would wear all-year-round.RELATED: How old is too old for a face mask?They also warn that when masks get wet -- say, due to breath perspiration catching on a face-covering -- they need to be laundered or replaced immediately."We have the paper, surgical masks – when those masks get wet, they need to be thrown away," said Dr. James Kravec, Chief Medical Officer at Mercy Health Youngstown in Ohio. "The cloth masks – when those get wet, they need to be laundered right away. Either mask, when they're wet, they're no longer effective."Kravec advised to put a COVID-preventative mask on first before layering up with a scarf, hat and gloves.

It's the kind of situation nobody wants to be in: getting sick unexpectedly and left with a hefty hospital bill to pay. But it's a situation Jamesia Shutt is all too familiar with. Three years ago, Shutt got sick and went to the emergency room in the middle of the night. "They did some X-rays, some morphine, gave me an antibiotic and sent me home in like two hours maybe,” Shutt recalls of the visit. “You have pneumonia, go home." That two-hour visit to the ER turned out be quite expensive. "A couple weeks later, I don't know when, I get a bill for ,000," she says. It’s a sticker shock she didn't see coming. "My thought is well, I'm not a doctor or a medical person, so I’m trusting this cost, whatever they say it's going to cost," she says. It’s a problem that David Silverstein, the founder of the non-profit group Broken Healthcare, sees it all the time. "Imagine if you and I went to a restaurant and we sat down at the same table at the same time with the same waiter and we're given the same menu with different prices on it, how would that make you feel? Well, this happens in healthcare every day," Silverstein says. Silverstein has been fighting to make sure patients aren't hit with what are called “surprise bills.” "The number one thing is ask a lot of questions and don't get frustrated by the answers,” he says. “As a consumer, you have rights. If they say they don't know, say that's not good enough." Silverstein says ask questions to find out if anyone doing the procedure is out of your insurance network. This year, the White House started requiring hospitals to list prices online. The issue with that is those prices are listed without factoring in insurance, which complicates things even more. "It does not help 99 percent of the population, but it's a step in the right direction,” Silverstein says. “We need transparency from both the providers and the insurance carriers.” When the president held this meeting last month, both Silverstein and Shutt were by his side, because they know the problem firsthand. "To have the president ask what happened and why do you have this medical bill was pretty incredible," Shutt says. Three years later, Broken Healthcare's attorneys are fighting Shutt’s hospital bill. "It is a game and Americans need to learn the rules of the game, and they need to learn their rights and play the game to win until such time our government officials do the right thing and change the rules, so we don't have to play this sleazy game anymore," Silverstein says. 2540
