Teen climate activist Greta Thunberg was all alone when she started protesting the lack of political action on climate change last year outside of the Swedish parliament. Today, climate strikes inspired by Thunberg are drawing out more than 1 million young people around the world. But as she tells Political Climate: the fight is “not over yet.”

This week’s podcast was recorded at the R20 Austrian World Summit in Vienna, where former California governor Arnold Schwarzenegger teamed up with Thunberg to call attention to the climate crisis. We sit down with Schwarzenegger to get his reaction to meeting Greta. Plus, we speak with the 16-year-old Swedish protester about her advice to climate activists in the U.S.

We also discuss takeaways from the recent EU Parliament elections, where Green Party members saw big gains in some of Europe’s largest countries. Could these results foreshadow a green wave in the next U.S. election?
