NBC Hosts Celebrate Teen Climate Activist: ‘Go, Greta, Go!’

WELKER: "Teenage climate change activist, Greta Thunberg, has completed her sailboat trip across the Atlantic to attend the United Nations Global Warming Conference. The Swedish 16-year-old and her crew arrived in New York yesterday, two weeks after heading out from England. Thunberg, who never sailed before, says she took the wind and solar powered yacht because flying is bad for the environment. She first made headlines last year by leading weekly school strikes to demand that world leaders address climate issues. She shared the journey with her 2 million social media followers. How incredible! She's just 16 years old."
MELVIN: "Go, Great, go!"
