"You and me, we're a team," Barack Obama said to Swedish teenage climate activist Greta Thunberg right before they fist bumped. Thunberg established herself as a bona fide climate action figure after staging weekly sit-ins outside the Swedish Parliament, spawning a movement of youth climate activists to hold their own protests in more than 100 cities worldwide. She arrived in New York last month after sailing across the Atlantic to speak at the United Nations Climate Action Summit. Thunberg traveled on a zero-emissions sailboat to reduce the environmental impact of her journey, according to a statement from her team. 📸: Obama Foundation #climateaction #climatecrisis #youthactivist #environment #GretaThunberg #BarackObama #politics #climatechange #activism #cnn
