Thunberg: People are underestimating 'the force of angry kids'2019|01:13
Climate change activist Greta Thunberg docked in Lisbon on Tuesday (December 3) after a 20-day Atlantic crossing in a catamaran. She's on her way to Madrid, where the COP25 climate summit is currently underway where she will demand urgent action on global warming. Thunberg refuses to travel by plane - and left New York on the boat, La Vagabonde, in November. Speaking shortly after disembarking, she told reporters and supporters that people are underestimating the force of angry kids.
