Students across the country are expected to walk out of their classrooms Wednesday morning to protest gun violence. The National School Walkout is scheduled to begin at 10 a.m. in every time zone and last for 17 minutes -- a minute for each life lost in the Parkland school shooting.If you're a student who's thinking of taking part (or the parent of one), you probably have lots of questions: Can the school retaliate? Will it hurt your chances of college? Can you just stay home for the day?For help with answers, we turned to a couple of experts: 1. Can my school punish me for taking part? 606

Texas Gov. Greg Abbott called for action on Friday in the wake of a deadly school shooting in Santa Fe, Texas."We need to do more than just pray for the victims and their families," said Abbott, a Republican, during a news conference in response to the shooting. "It's time in Texas that we take action to step up and make sure this tragedy is never repeated ever again in the history of the state of Texas."Abbott said he plans to convene "roundtable discussions" next week that will bring together lawmakers and community members with a wide array of perspectives.RELATED: Trump on Texas school shooting: 'This has been going on too long in our country'"Beginning immediately, I'm going to be working with members of the Texas Legislature but also members of our communities across the entire state of Texas, to begin with roundtable discussions beginning next week where we will assemble all stakeholders to begin to work immediately on swift solutions to prevent tragedies like this from ever happening again," Abbott said.The governor added he wants input from parents, students, teachers and gun rights supporters.Abbott suggested he hopes the discussions will lead to legislation: "We want to hear from everybody who has an interest in what has happened today, so we can work together on putting together laws that will protect Second Amendment rights but at the same time ensure that our communities and especially our schools are safer places."Lawmakers across the country condemned the shooting on Friday. President Donald Trump said in remarks from the White House that mass shootings have been "going on too long in our country."Ten people were killed in the shooting Friday morning at Santa Fe High School and another 10 were wounded, Abbott said during his news conference.The governor called it "the worst disaster ever to strike this community."The-CNN-Wire 1881

The Arctic is experiencing a multi-year stretch of unparalleled warmth "that is unlike any period on record," according to the 2018 Arctic Report Card, a peer-reviewed report released Tuesday morning from the National Oceanic and Atmospheric Administration, an agency within the United States Department of Commerce.The report states that human-caused climate change is transforming the Arctic, both physically through the reduction of sea ice, and biologically through reductions in wildlife populations and introduction of marine toxins and algae.The report is yet another study from part of the US government indicating that climate change is real and having a profound impact, despite denials from the President and senior members of his Administration.Temperatures in the Arctic are warming more than twice as fast as the overall planet's average temperature, with temperatures this year in the highest latitudes (above 60 degrees north) coming in 1.7 degrees Celsius (3.1 degrees Fahrenheit) above the 1981-2010 average. These were the second warmest (behind 2016) air temperatures ever recorded during the Arctic year, which runs from October through September to avoid splitting the winter season.The five years since 2014 have been warmer than any other years in the historical record, which goes back to 1900. Although Arctic temperatures have been subject to wild swings back and forth through the decades due to natural variability, they have been consistently warmer than average since 2000 and at or near record since 2014, the report states."The changes we are witnessing in the Arctic are sufficiently rapid that they cannot be explained without considering our impacts on the chemistry of the atmosphere," Thomas Mote, a research scientist at the University of Georgia who authored part of the report, told CNN in an email.Mote expressed than any natural cycle or mechanism that would lead to the amount of warming and ice loss that has been observed would take much longer than the few years over which we have seen these drastic changes. 2074

Stevie Wonder has joined Twitter and his first tweet did not disappoint.The Grammy-winning superstar paid tribute to Dr. Martin Luther King on Wednesday in his inaugural tweet posted shortly after 8 p.m. ET. The timing of the tweet appears to coincide with the moment the civil rights leader was pronounced dead fifty years ago.The tweet came with a star-studded video in which the Obamas and celebrities such as Common, Bette Midler, and Billy Crystal talked about their own dreams -- a nod to King's famous "I Have A Dream" speech. King delivered the speech five years before he was assassinated in Memphis."On April 4th, 1968 at 7:05 p.m. central time, Dr. King's life was cut tragically short. 50 years later a need for his dream to be fulfilled is far greater than ever," Wonder tweeted on Wednesday. "Share your dream & post your own #DreamStillLives video. Spread love...spread hope."Wonder called in a host of famous friends from politics, sports, business, music and entertainment to help him with the video tribute. Kamala Harris, Dave Chappelle, Warren Buffett, Bon Jovi, Katy Perry, Serena Williams and Smokey Robinson also made appearances in the five-minute video. 1190
