Greenland's massive ice sheets contain enough water to raise global sea levels by 23 feet, and a new study shows that they are melting at a rate "unprecedented" over centuries -- and likely thousands of years.The study, published Thursday in the scientific journal Nature, found that Greenland's ice loss accelerated rapidly in the past two decades after remaining relatively stable since the dawn of the Industrial Revolution in the mid-1800s.Today, Greenland's ice sheets are melting at a rate 50% higher than pre-industrial levels and 33% above 20th-century levels, the scientists found.Greenland's melting glaciers may someday flood your city"What we were able to show is that the melting that Greenland is experiencing today is really unprecedented and off the charts in the longer-term context," said Sarah Das, an associate scientist at the Woods Hole Oceanographic Institution and a co-author of the study.To determine just how fast Greenland's ice is retreating compared with the past, scientists used a drill the size of a traffic light pole to take ice core samples.The samples were taken from sites more than 6,000 feet above sea level, giving the researchers a window into melting on the ice sheet over the past several centuries.In the wake of October's dire report from the UN Intergovernmental Panel on Climate Change warning that civilization has just more than a decade to stave off climate catastrophe, Thursday's report spells more bad news for the planet, especially the millions of people living near the world's oceans.Melting from Greenland's ice sheet is the largest single driver of global sea level rise, which scientists predict could swamp coastal cities and settlements in the coming decades.Eight of the 10 largest cities in the world are near coasts, and 40% to 50% of the global population lives in coastal areas vulnerable to rising seas.The study also found that Greenland's ice loss is driven primarily by warmer summer air and that even small rises in temperature can trigger exponential increases in the ice's melt rate."As the atmosphere continues to warm, melting will outpace that warming and continue to accelerate," said Luke Trusel, an assistant professor at Rowan University and study co-author.According to Trusel, the current thought in the scientific community is that there is a temperature threshold that could trigger a point of no return for the eventual melting of Greenland and Antarctica's ice sheets. And though we don't know exactly what that temperature tipping point is, "what's clear is that the more we warm, the more ice melts.""Once the ice sheets reach these tipping points, it's thought that they'll go into a state of irreversible retreat, so they'll be responding to what we do now for centuries and milliennia into the future," Trusel said.What it's like at the ground zero of climate changeDas stressed that although climate science often focuses on the future impacts of warming, the findings show that the climate is already undergoing hugely significant changes."Climate change -- whether it's in Greenland or in your backyard -- is already here and already happening and already impacting people. It's not something that's coming in the future, and this study really drives home that point," she said.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.

Health officials say the U.S. faces an uphill battle in convincing some Americans to take a potential COVID-19 vaccine. While polling shows Americans have been more open to a vaccine in recent months, there is still skepticism in vaccines among non-whites across the country.Experts say that Black people, in particular, remain skeptical of vaccines due to past failings of the U.S. healthcare system, in particular, the Tuskegee syphilis study. But the National Medical Association — a nonprofit representing the interests of Black doctors across the country — is trying to fight that skepticism ahead of the potential authorization of a COVID-19 vaccine."We're already suffering more than other community, and we would hate to see that suffering gap widen because members of our community did not affect to receive a vaccine that could have prevented kidney disease, prevented lung damage from COVID-19," Dr. Leon McDougle, the president of the National Medical Association said.The National Medical Association's task force has been doing its own independent vetting of potential COVID-19 vaccines, and McDougle added they are doing so to ensure that politicians are not influencing the Food and Drug Administration (FDA)."We are trusted messengers for health in the Black community," McDougle said. "That's where we live. That's where we work, and we already have those established relationships."The group has already had two meetings with Pfizer — the company, who on Wednesday, said it is days away from filing for Emergency Use Authorization for its vaccine candidate — and has a third meeting planned.The Association has also met with Moderna and AstraZeneca about their vaccine trials.McDougle added that since the group has been having meetings with vaccine makers for a while, he's hopeful the Association will agree with the FDA's decisions.McDougle says the National Medical Association has already been collaborating with clergy and other professional organizations that are looking to them for a direction on the vaccine. 2045

GRETNA, Fla. — “He started screaming oh my god, oh my god!” Gayle Sweet recalled Thursday as she sobbed in pain while sitting inside of a pickup truck in the driveway of her Gretna, Florida Home. Her husband, Steve, is one of six confirmed fatalities, so far, in the aftermath of Hurricane Michael.Sweet says she and her husband were on the front porch of their mobile home when she heard what sounded like a freight train. Moments later, she says she watched as all the trees around them started leaning to the side. Steve yelled, 'Get inside the house!' she recalled.Seconds later, a huge oak tree fell on top of the house, landing on top of Steve and pinning Sweet inside for hours. 698

Grocery chain Kroger announced Tuesday that is plans to hire 1,000 people to administer coronavirus vaccines at the chain’s 2,200 pharmacies and 220 clinics.Kroger’s vaccine program launches this week in the state of Alaska as health care workers in Anchorage and Juneau will be vaccinated by Kroger staff. Kroger says that it is working with state and federal officials to vaccinate others in prioritized populations, such as health care workers, and those living and working in assisted living facilities.Kroger is not the only major company to assist in administering vaccines. CVS and Walgreens began administering vaccines to those living and working in assisted living facilities this week.“Kroger Health is a COVID-19 response leader that has provided our patients, associates and other businesses with diagnostic testing tools and supporting resources since the onset of this public health crisis,” said Colleen Lindholz, Kroger Health’s president. “Kroger Health’s experienced health care providers remain committed to helping our patients and associates live healthier lives. The size and scale of our health care operation provides us with the unique ability to efficiently facilitate COVID-19 testing and immunize a large portion of the U.S. population, once the authorized vaccines become more widely available.”There have been two coronavirus vaccines authorized by the FDA.Moderna’s vaccine has been hailed as a medical breakthrough. The vaccine has been considered 94.1% effective against the virus. According to Moderna, none of the thousands who were given two shots of the vaccine had severe COVID-19 symptoms. That is compared to 30 patients who were given a placebo who had symptoms.Pfizer’s vaccine has an effectiveness of 95%. It too comes in two shots.Those wishing to apply to assist in administering vaccines, click here. 1855

Hotels are still struggling to fill rooms like they were before an avalanche of cancellations starting in March.Now, travelers are slowly returning to train stations, airports, and hotels.“This is something that none of us were expecting or were prepared for,” said Daniel del Olmo, the President and COO of Sage Hotel Management, a Sage Hospitality Group company. Sage Hospitality Group manages 52 hotels across the U.S.“We went from basically a level of revenue of million on a daily basis to effectively ,000 per day in early May,” del Olmo said.“The economic impact has been something that no one could have ever prepared for, you could not have prepared for it financially, you could not have even prepared for it psychologically or emotionally,” said Chip Rogers, President of the American Hotel & Lodging Association. “2020 will go down on record of having the lowest occupancy in the history of the hotel industry and that includes during the Great Depression.”The association represented the entire industry from large brands to small hotels.For smaller companies, the impact of COVID-19 is especially difficult on their bottom line. “Well over 60% of all hotels are actually classified as small businesses by the Small Business Association,” Rogers said.“In the third week of March, we found ourselves having to furlough over 90% of our staff,” del Olmo said.“With no further assistance, about two thirds of hotels say they cannot make it another six months,” Rogers said. Del Olmo said they haven’t reached that point.“We have not had to permanently close, thankfully, any of our properties,” he said. But others have. Fewer visitors means less money and less work.“We’re right at almost 2 million jobs lost in the hotel industry,” Rogers said.Del Olmo said Sage Hospitality had to furlough 5,000 employees, then eventually lay off 4,000. “What keeps us up at night,” Del Olmo said, “is how we bring our associates back to work.”In the meantime, the group is providing help for former employees. “We initially established a Sage Associate Relief Fund, which allowed us to basically provide pantry items to our associates in need,” he said.While employees still on the job were given more tasks to help fill the gap. “Everybody basically on the teams is doing multiple jobs that, in the past, they might have never done before. We have general managers that on a daily basis strip beds and run the parking,” Del Olmo explained.As hotels continue to balance health, safety and running a business, they are getting creative with ways to bring in revenue, such as hosting micro weddings and hallways concerts with musicians.“Basically roaming the halls. You basically could be listening from the comfort and safety of the entry from your room,” Del Olmo said.Even with the creative new solutions, Rogers said without aid or an uptick in travel, some hotels may suffer.“We may be a much smaller industry in the next couple of years but we will adapt,” Rogers said. 2988
