Greta Thunberg on the "advantage" of Asperger's in fighting climate change: "We need people who think outside the box"
At 16, climate activist Greta Thunberg has been called the greatest threat to the world's fossil fuel industry. The teenager first made headlines last year with her solitary strike against climate change outside Sweden's parliament – since then, she's inspired millions of supporters to rally in more than 150 countries. Thunberg joins "CBS This Morning" for her first live U.S. television interview.
