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.

Georgia Sec. of State Brad Raffensperger said Wednesday that the state would conduct a hand recount in the 2020 presidential election.Raffensperger said a hand recount would help reassure voters of the integrity of the election. According to The Associated Press, Raffensperger says he wants the process to begin this week and expects the recount to be finished by Nov. 20.Under Georgia law, candidates are entitled to request a recount if the outcome percentage is within 0.5%. Biden currently holds a 0.28% lead in the state. Raffensperger says once the hand recount is finished, the losing candidate can then request a second machine hand recount.The presidential race between Donald Trump and Joe Biden in the state remains too close to call, though Biden holds a lead of more than 14,000 votes in the state with 99% of the vote count.Recounts typically only affect the outcome of about a few hundred votes. In a 2016 recount of the presidential election in Wisconsin — which went to Trump by a margin of about 20,000 votes — the outcome only shifted about 500 votes. A recount in Florida in 2000 did have an impact on the election, as it was the tipping-point state in the election and was decided by about 500 votes.Officials in Georgia have not reported any systematic issues with the vote that would indicate widespread issues in tallying.Even if the vote count were to flip in Georgia, Biden is projected to still have more than the required 270 electoral votes to claim the presidency. The Associated Press projects that Biden has picked up 290 electoral votes with Georgia still too close to call. 1616

GRANDVIEW, Mo. — It's something many women dream about for years: the dress she'll walk down the aisle in to say "I do."One Kansas City-area bride about to be married is giving hers away to another bride going through a difficult time.Grandview resident Taylor Cooper will marry her fiance, Nick Amor, on Oct. 10. Cooper originally planned to have two wedding dresses, one to wear during her ceremony and the other during her reception.After downsizing her wedding due to the COVID-19 pandemic, she didn't think the wardrobe change would be appropriate and wanted the extra dress to go to a bride who could use some help.Cooper said she recently landed her dream job and feels blessed she has not faced many difficulties because of the pandemic."I just wanted to think of a way to give back to somebody that had been impacted," Cooper said. "I never really thought in my life that I would be in a position that I could gift something like this."She posted in a bridal Facebook group saying she was looking for a bride in need of a dress, and she was quickly connected with a bride in Georgia."She's just such a sweetheart, she literally has texted me every single day since I told her I was going to give it to her, and she's like 'I can't thank you enough,'" Cooper said.Cooper packed up the dress Wednesday to ship it to its new owner."I feel like it's going where it belongs," Cooper said.Cooper's October wedding is one of many happening this fall.Megan Julian, the founder of Julian Events in Kansas City, said she's seeing fewer couples canceling or postponing weddings and moving to smaller weddings instead."What we're finding is couples are surprised by what they can do with their original plans on a smaller scale," Julian said.Julian said many couples are also incorporating virtual aspects to their weddings so they can keep their original guest list.As Cooper prepares to send off her dress, she hopes to inspire others to lend a helping hand if they can."It doesn't really matter how big or small, I just think any nice gesture we can do for each other these days is just so important," Cooper said.This story originally reported by Emma James on kshb.com. 2180

GLENDALE, AZ — It's official: The San Francisco 49ers will play their next two home games in Arizona after local COVID-19 restrictions prevented them from playing at their home field."The San Francisco 49ers have come to an agreement with the National Football League and Arizona Cardinals which allows the 49ers to host their Weeks 13 and 14 home games against the Buffalo Bills and Washington Football Team at State Farm Stadium in Arizona," the 49ers said Monday in a statement.Over the weekend, California's Santa Clara County announced a number of new COVID-19 restrictions, which banned all sports — professional, collegiate, and youth — and required people to quarantine for two weeks if they traveled 150 miles away.Levi's Stadium, home to the 49ers, is located in Santa Clara County."The Cardinals organization, State Farm Stadium and League officials have been supportive and accommodating as we work through the many logistical issues involved in relocating NFL games," the Arizona Cardinals said in a statement.The Cardinals will host the Los Angeles Rams at State Farm Stadium on Sunday, Dec. 6. Previously, the team announced that no fans aside from a limited number of staff and players' families would be allowed inside the stadium.The 49ers will host the Buffalo Bills in Arizona on Monday, Dec. 7, and will then host the Washington Football Team there on Dec. 13.This story was originally published by KNXV in Phoenix, Arizona. 1453

Hospitals and states collecting case data on COVID-19 patients will now be reporting that data directly to the federal government, instead of the CDC's online database.Beginning this week, according to an update on the Health and Human Services website, states and hospitals are being asked to submit data directly to the federal government and task force in an effort to cut down on duplicate requests and minimize the reporting burden on hospitals and facilities.“As of July 15,, 2020, hospitals should no longer report the Covid-19 information in this document to the National Healthcare Safety Network site,” the statement reads. The emphasis was added in the original document.The National Healthcare Safety Network site is the CDC’s site for tracking infectious diseases.The document says the change in reporting will help the White House coronavirus task force to allocate supplies like personal protective gear, ventilators and drugs like remdesivir.Some are worried the change in where the data will be kept means a change in public access to the data.“Historically, C.D.C. has been the place where public health data has been sent, and this raises questions about not just access for researchers but access for reporters, access for the public to try to better understand what is happening with the outbreak," Jen Kates, the director of global health and H.I.V. policy with the nonpartisan Kaiser Family Foundation, told the the New York Times, who first reported on this change.Many researchers, scientific modelers and health officials in municipalities around the country rely on the CDC’s data to make projections and time-sensitive decisions.Michael Caputo, the assistant secretary for public affairs at the department, said in a statement to CNN, a "new faster and complete data system is what our nation needs to defeat the coronavirus and the CDC, an operating division of HHS, will certainly participate in this streamlined all-of-government response. They will simply no longer control it."The document shared by Health and Human Services does not clarify how the data will be accessed by the public. 2128
