paragraph_text: Participation at COP25
  
  Thunberg had intended to remain in the Americas to travel overland to attend the 2019 United Nations Climate Change Conference (COP25) originally planned in Santiago, Chile, in December. However, it was announced on short notice that COP25 was to be moved to Madrid, Spain, because of serious public unrest in Chile. Thunberg has refused to fly because of the carbon emissions from air travel, so she posted on social media that she needed a ride across the Atlantic Ocean. Riley Whitelum and his wife, Elayna Carausu, two Australians who had been sailing around the world aboard their 48-foot (15 m) catamaran La Vagabonde, offered to take her. On 13 November 2019, Thunberg set sail from Hampton, Virginia, for Lisbon, Portugal. Her departing message was the same as it has been since she began her activism: "My message to the Americans is the same as to everyone – that is to unite behind the science and to act on the science."
  
  Thunberg arrived in the Port of Lisbon on 3 December 2019, then travelled on to Madrid to speak at COP25 and to participate with the local Fridays for Future climate strikers. During a press conference before the march, she called for more "concrete action", arguing that the global wave of school strikes over the previous year had "achieved nothing" because greenhouse gas emissions were still rising – by 4% since 2015.
