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.

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

Gab has been taken offline following revelations that the suspected Pittsburgh synagogue gunman used the social network to threaten Jews.A statement on the platform's website Monday said it would be "inaccessible for a period of time" after several web hosting services declined its business.Gab said it has also been removed from app stores and refused service by payment processing firms."Gab.com is under attack," the company said in the statement. "We have been systematically no-platformed [and] smeared by the mainstream media for defending free expression and individual liberty for all people."The platform has come under scrutiny after it emerged that suspected gunman Robert Bowers frequently targeted Jews in his Gab posts, and even logged onto the platform shortly before allegedly killing 11 people at the Tree of Life synagogue. 850
