After two weeks at sea, Greta Thunberg arrived in America. Boris Herrmann and Team Malizia sailed Greta across the North Atlantic - from Plymouth to New York. Thunberg is determined to tell U.S. policy makers a thing or two about climate change at the United Nations in Manhattan.

Swedish climate activist Greta Thunberg is traveling to New York by sailboat to speak at the United Nations Climate Action Summit in September.

The 16-year old Thunberg and her father are being ferried across the North Atlantic by professional offshore sailor Boris Herrmann and his teammate Pierre Casiraghi aboard Malizia II — a foiling IMOCA 60 racing sailboat.

Sailing, she says, will limit her carbon footprint.

Thunberg started a school strike every Friday in front of the Swedish parliament to send a clear message to politicians, and says the strikes will continue until Sweden is in alignment with the Paris Climate Accord.She has inspired kids in many countries to follow suit. Social hashtags are #FridaysForFuture and #SS4C.

Team Malizia is collaborating with the Max Planck Institute for Meteorology in Munich, and the Geomar Helmholtz Center for Ocean Research in Kiel, Germany. They have outfitted the boat with CO2 sensors and are collecting ocean data on all of their voyages.
