Hampton (AP) - Climate activist Greta Thunberg has found an environmentally friendly ride from the US to Europe. She will sail with friends on a catamaran from the east coast of the United States to Europe tweeted the 16-year-old Swede. In Madrid, Thunberg wants to attend the UN Climate Change Conference in December. The "La Vagabonde" of the Australian couple Riley Whitelum and Elayna Carausu is scheduled to leave today.
