COPENHAGEN, Denmark (AP) — Scientists say an enormous chunk of Greenland’s ice cap, estimated to be about 110 square kilometers (42.3 square miles), has broken off in the far northeastern Arctic. For comparison, Manhattan is roughly 22 square miles. They see it as evidence of rapid climate change, which is leading to the disintegration of the Arctic's largest remaining ice shelf. The section broke off a 50-mile long fjord at the front end of the Northeast Greenland Ice Stream, where it flows off the land and into the ocean. One scientist says “we should be very concerned” about the ice loss. In August, a study showed that Greenland lost a record amount of ice during an extra warm 2019. 702

CNN commentator and former Pennsylvania GOP Sen. Rick Santorum on Sunday suggested students protesting for gun control legislation would be better served by taking CPR classes and preparing for active shooter scenarios."How about kids instead of looking to someone else to solve their problem, do something about maybe taking CPR classes or trying to deal with situations that when there is a violent shooter that you can actually respond to that," Santorum said on CNN's "State of the Union."Santorum's comments came?a day after protesters assembled at March for Our Lives events in Washington and across the country to demand gun control legislation in the wake of the deadly school shooting in Parkland, Florida.Santorum dismissed the usefulness of "phony gun laws" and appeared to call on students and others to improve their communities and to prepare to respond to further shootings instead of calling for new laws."They took action to ask someone to pass a law," Santorum said. "They didn't take action to say, 'How do I, as an individual, deal with this problem? How am I going to do something about stopping bullying within my own community? What am I going to do to actually help respond to a shooter?'... Those are the kind of things where you can take it internally, and say, 'Here's how I'm going to deal with this. Here's how I'm going to help the situation,' instead of going and protesting and saying, 'Oh, someone else needs to pass a law to protect me.'"Van Jones, a liberal CNN commentator, interjected and mentioned his own child was about to start high school."I want him focused on algebra and other stuff," Jones said. "If his main way to survive high school is learning CPR so when his friends get shot ... that to me, we've gone too far. I'm proud of these kids. I know you're proud of these kids too."Santorum responded by continuing to knock gun control efforts."I'm proud of them," he said. "But I think everyone should be responsible and deal with the problems that we have to confront in our lives. And ignoring those problems and saying they're not going to come to me and saying some phony gun law is gonna solve it. Phony gun laws don't solve these problems."Santorum's comments prompted a statement from Everytown for Gun Safety program manager Erica Lafferty, whose mother was shot and killed in the Sandy Hook Elementary School shooting.The statement read: "Rick Santorum's words are an insult to the kids of Parkland, my family and to the countless others who have had loved ones taken by gun violence. My mother was killed while protecting her students at Sandy Hook School. For anyone to suggest that the solution to gun violence is for kids to learn CPR is outrageous, and indicative of the NRA's desire to do or say anything except strengthen America's weak gun laws." 2822

CLEVELAND — Cleveland Browns quarterback Baker Mayfield plans to kneel during the national anthem during the upcoming NFL season, according to a comment he made on Instagram.Mayfield posted a video of a training session on his Instagram Saturday afternoon.In the comments, an Instagram user asked him to tell Browns fans that he wasn't going to kneel this season, to which Mayfield replied, "Pull your head out. I absolutely am."His comment quickly gained traction among Browns fans and beat reporters. Later Mayfield explained his decision further in a statement on his Instagram story.Everybody so upset about my comment doesn't understand the reasoning behind kneeling in the first place....(ex-Green Beret and Seattle Seahawk) Nate (Boyer) and (former 49ers quarterback Colin Kaepernick) came to an agreement that kneeling was the most respectful way to support our military while also standing up for equality.I have the utmost respect for our military, cops, and people that serve OUR country. It's about equality and everybody being treated the same because we are all human. It's been ignored for too long and that is my fault as well for not becoming more educated and staying silent.If I lose fans, that's okay. I've always spoken my mind. And that's from the heart.Mayfield was one of the 1,400 current and former professional athletes and coaches from across the National Football League (including many from the Cleveland Browns), the National Basketball Association and Major League Baseball, who signed a letter from the Players Coalition to the United States Congress urging the passage of a bill to end qualified immunity as a way to combat police violence and racial injustices in the country.Mayfield's teammates, wide receivers Jarvis Landry and Odell Beckham Jr., previously participated in a video alongside other NFL stars to call for the league to address issues including silencing players from peacefully protesting and failing to vocally condemn racism and systematic oppression.NFL commissioner Roger Goodell later responded to the video, echoing the words requested by the group and stating that the league was wrong for "not listening to NFL players earlier" when it came to protesting police brutality.This story was originally published by Camryn Justice on WEWS in Cleveland. 2316

COLORADO SPRINGS, Colo. — The back and forth between President Donald Trump and North Korea's president Kim Jung Un is constant. But what if North Korea acted on its threat of sending a nuclear missile to American shores? An Air Force base in Colorado Springs would play a critical role in the event of such an attack.If the unthinkable happens, soldiers in a secure room on Schriever Air Force Base in Colorado Springs will fight back. From a fortified facility, they have the power to launch what's known as a kill vehicle. Propelled into space by a rocket, the kill vehicle can destroy a warhead above the earth.The mission would be administered by members of the 100th Missile Defense Brigade."The threat we're dealing with is very real," said Colonel Kevin Kick, who is the commander of the 300-person team. "We say we are the 300 defending the 300 million."From their hub in Colorado, the interceptors can be launched from bases in Alaska and California, obliterating a nuclear warhead in a matter of minutes.The U.S. military allowed Denver7 television station, owned by the E.W. Scripps Company, to capture an exercise of a simulated attack on Los Angeles. Security is so sensitive, we can't tell you the participant's names.Soldiers say they train constantly so they are prepared in the event of an attack. “We train continuously — every shift, multiple times," said one unnamed solider.During our visit, the computer monitors were blacked out and had post-it notes covering the information— part of the efforts to prevent a breach."It's a very humbling experience to know that we are responsible for the defense of the homeland for the entire United States," said Lt. Alberto Squatrito .These soldiers are the best of the best— a blend of active military and National Guard, who work side-by-side after passing some of the toughest tests in the military."Unlike most school houses in our Army, you have to have an ‘A’ average just to pass the course," said Kick.And that makes sense, considering they're at the controls that can determine life and death or prevent a nuclear annihilation."Do you ever get a lump in your throat, knowing the seriousness and importance of what you do here?" asked Denver7’s Marc Stewart."Yes, I do get a sense of pride. I do get a lump in my throat. We're here to keep America safe," said the soldier.But not everyone is convinced this system will work. Some Pentagon testing has shown failures, with only about half of the tests being successful.Yet the technology is constantly being upgraded and revised. The soldiers tell Denver7 they stand behind it, saying they sleep at night feeling safe. 2675

CITY HEIGHTS, Calif. (KGTV) - A woman in City Heights said she discovered a power cord connected to her building’s utility box, leading into nearby Swan Canyon.After pulling it up, she said it was connected to a power strip and phone charger. She suspects it was being used by homeless people who live in the canyon.The woman did not want to be identified, saying the transients in the area have been aggressive at defending their campsites. She’s worried about the safety of her and her young children, who often like to walk on the trails.She believes the cord wasn’t there for more than a day, though she claims neighbors have also sighted people using the outlet to charge phones.She said she’s worried less about her electricity bill than the potential for the haphazard wiring to spark fires in the dry open space.Her husband, who works for the property manager, put a new lock on the utility closet though she suspects it won’t last long. It’s been ripped open before.She said they’ve reached out to SDG&E and have reported the issues to the city on the “Get it done” app.  1097
