Greta Thunberg’s UN speech: We’ll not let you get away with this

An emotional Greta Thunberg sent a stern warning to world leaders to act and address climate change. The 16-year-old Swedish teenage activist delivered her four-minute long speech at the United Nations Climate Action Summit in New York on Monday. Thunberg has galvanised young people around the world since she started protesting alone with a sign outside the Swedish parliament building in Aug 2018.
