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.

Heading into the pandemic, 16 million US workers were employed by the restaurant industry, making it one of the largest industries in America.With the coronavirus still spreading throughout the US, whether it’s safe to visit a restaurant remains a question on the minds of many. For many Americans, they’re not quite sold on restaurants being safe despite most restaurants taking measures to protect staff and customers.ValuePenguin, which is associated with Lending Tree, conducted a survey of 1,000 Americans. The survey found that 44% of Americans feel indoor restaurants are unsafe to visit amid a pandemic, compared to 40% who believe they are safe. Women were more likely to say indoor dining is unsafe compared to men.More consumers, however, say getting takeout and dining outdoors is safe. Nearly 67% of respondents felt it’s safe to get takeout, and 58% said eating outdoors is safe.What do experts say?Many experts have said even with the precautions restaurants are taking, there is still a sizeable risk of catching the virus while dining inside. These risks, however, are generally significantly lower for those dining outside.Last month in an interview with MSNBC, Dr. Anthony Fauci pointed toward restaurants being among riskiest places to visit amid the pandemic. Fauci added that bars and gyms also are considered risky in his view.“When you have restaurants indoors in a situation where you have a high degree of infection in the community [and] you're not wearing masks, that's a problem,” Dr. Fauci said.Fauci pointed toward a September 2020 CDC study that found those who visited restaurants in the previous two weeks were two times more likely to test positive for the coronavirus than those who said they had not been inside a restaurant.“Reports of exposures in restaurants have been linked to air circulation,” the CDC said. “Direction, ventilation, and intensity of airflow might affect virus transmission, even if social distancing measures and mask use are implemented according to current guidance. Masks cannot be effectively worn while eating and drinking, whereas shopping and numerous other indoor activities do not preclude mask use.”Economic impact to restaurantsWith many restaurants forced to close indoor operations during the spring, and scale back indoor capacity during the summer, millions were out of work. According to the National Restaurant Association, 8 million restaurant workers, representing nearly half of the industry, were without jobs during the height of the pandemic. There remained over 2 million out-of-work restaurant employees as of the start of October.As of Wednesday, 100,000 restaurants have either closed for good, or for a significant period of time. As a whole, the restaurant industry is expected to lose 0 billion by the end of 2020.In hopes of minimizing spread and regaining customer confidence, the CDC and industry leaders have implemented cleaning procedures. They hope as cases begin to swell again for the cold-weather season, restaurants can remain open amid the pandemic. 3062

Have you ever given a gift that was intentionally inconsiderate? Maybe you even received one over the years.   Deborah Cohn, a consumer analyst, says when it comes to the worst gift givers, there are five types.  The Confrontational Gift GiverConfrontational gifts are usually given to send a message.   "Every year, my father would buy us stuff for our house like a weed wacker, leaf blower, to be like, ‘Your house is a mess,’" describes one woman.  The Selfish Gift GiverThis type of gift giver can be in a relationship. An example is when you buy your spouse a big screen TV for Christmas, but the TV is something you know you want to enjoy.The Obligatory Gift GiverIt’s the last-minute gift, with no thought behind it. That can include a gift card.The Aggressive Gift GiverThen, there is the aggressive gift, the ones that are explicitly meant to offend.The Competitive Gift GiverThis may apply to the competitive people you know. The gift giver who tries to outdo everyone else’s gift.   Whether you're buying gifts for family or for friends this year, instead of being petty, try to put a little thought into the gifts your giving.    1199

Grocery chain Kroger is reportedly considering banning all Visa card transactions at its locations throughout the United States due to a dispute on swipe fees, Bloomberg reported. Kroger is reportedly taking the first step toward stopping Visa transactions. At its Foods Co. Supermarkets, which are located in California, the chain will stop accepting Visa transactions next month, Bloomberg reported. “It’s pretty clear we need to move down this path, and if we have to expand that beyond Foods Co., we’re prepared to take that step,” Kroger spokesperson Chris Hjelm told Bloomberg. "When the amount retailers pay in card fees gets out of alignment, as we believe it is now, we don’t believe we have a choice but to use whatever mechanism possible to get it back in alignment.”While Kroger itself has grocery stores in 21 states, Kroger owns a number of regional chains throughout the country — Baker’s, City Market, Dillons, Food 4 Less, Fred Meyer, Fry’s, Gerbes, King Soopers, Jay C, Food Store, Owens Market, Pay-Less Super Markets, QFC, Ralphs and Smith’s Food and DrugVisa issued a response to Kroger's announcement. "Visa is disappointed at Kroger’s decision to stop accepting Visa credit cards at its Foods Co. stores. When consumer choice is limited, nobody wins. Our goal is to protect the interests of our cardholders to ensure they can use their Visa credit cards wherever they shop. Visa remains committed to working with Kroger to reach a reasonable solution," Visa said in a statement. According to the National Retail Federation, roughly 2 percent of all transactions go toward swipe fees.  1660
