Former U.S. President Barack Obama met with Swedish teenage climate activist Greta Thunberg in Washington, Tuesday, September 17. Swedish teenage climate activist Greta Thunberg appeared before a U.S. Congressional committee Wednesday, urging law makers to "listen to the science" and take action on global climate change. The 16-year-old Thunberg has been in Washington since last week when she joined U.S. and indigenous activists for a protest designed to build support for a global climate strike on Friday and put pressure on lawmakers to take action on climate change. She was one of four students to appear Wednesday before a joint hearing of the House Foreign Affairs Subcommittee on Europe, Eurasia, Energy, and the Environment and the Select Committee on the Climate Crisis. https://www.voanews.com/usa/swedish-teen-climate-activist-urges-us-lawmakers-follow-science
