Climate activist Greta Thunberg speaks live from New York

Swedish climate change activist Greta Thunberg arrived in New York City on Wednesday after traveling across the Atlantic Ocean in a zero-emission yacht. She is in New York to attend the United Nations climate change summit on September 23.

Thunberg, 16, used the boat to raise awareness to the greenhouse gases emitted by the use of commercial airplanes. She tweeted that her vessel, named Malizia II, anchored off Coney Island Wednesday morning and that they were in the process of “clearing immigration and customs.” She is scheduled to speak to reporters Wednesday afternoon.

Thunberg’s yacht had no kitchen, no heating, no fridge and no bathroom. The vessel generated electricity through solar panels and wind turbines. Thunberg documented parts of her journey on Twitter, where she included videos of the high seas, photos of herself and the crew, and short commentaries about climate change.

On Day Four, she described conditions on Malizia II “like camping on a roller coaster.” Some of her videos even demonstrated the difficult conditions her crew experienced while on the journey. 

Thunberg recently celebrated the one-year anniversary of the start of her climate change movement. Last August, she began striking alone outside the Swedish parliament, and soon, students around the world began walking out of school, demanding action from their governments. She’s been called “the voice of the planet,” and has even been nominated for the Nobel Peace Prize. 

While she’s here in the U.S., Greta will attend two global climate strikes in addition to the U.N. summits. It’s unclear how she plans to eventually travel back home.
