On Friday, groups of students around the world plan to walk out of classes and hold marches and protests to demand government action on climate change.Globally, the youth protests are being inspired by a 16-year-old Swedish climate activist named Greta Thunberg. She held a press conference on the steps of the U.S. Supreme Court today and told elected officials: “I don’t want you to listen to me, I want you to listen to the scientists and I want you to unite behind the science.”In Baltimore, several students have been influenced by Thunberg’s leadership. A coalition of activists plans to meet at 8:30 am on Friday at the Bryn Mawr School at 109 West Melrose Avenue in North Baltimore. The students will then march south down Charles Street and hold a demonstration at noon at the Inner Harbor.
