Teenage climate change activist Greta Thunberg is to sail across the Atlantic to reach UN climate summits.
The 16-year-old campaigner, who has inspired thousands of young people to join her protests, will travel to America the old-fashioned way.
She said she spent months trying to work out how she could make her journey without flying.
The teen tweeted that she will leave Britain on a high-tech racing yacht to attend the UN climate summits: in New York in September and in Chile in December.
In an interview during her weekly Fridays For Future protest outside the Swedish parliament in Stockholm, Greta said: “I have countless people helping me, trying to contact different boats.”
Greta plans to take a year off school to keep raising awareness of climate change and pressuring world leaders to step up efforts to curb global warming.
Since starting her "school strikes" in August 2018, Greta has appeared before leaders at last year's UN climate conference in Poland and harangued business and political leaders at the World Economic Forum in Davos, Switzerland.
She also met Pope Francis, who praised Greta's efforts and encouraged her to continue campaigning.
Although little-known in the United States, Greta has arguably become the figurehead for a new generation of European eco-activists worried that they will suffer the fallout from their parents' and grandparents' unwillingness to take strong actions to combat climate change.
"This past year, my life has turned upside down," Greta said.
Aside from attending a summit hosted by UN secretary general Antonio Guterres on the sidelines of the global body's annual assembly on September 23, Greta plans to take part in several climate protests in New York.
