Climate activist Greta Thunberg is making headlines again. On Monday, she accused world leaders of failing her generation and did so with a charismatic speech at the United Nations Climate Action Summit.
Thunberg emphasized that the science behind climate change has been “crystal clear” for more than 30 years, and yet the most powerful people on Earth had failed to take meaningful action. “You are still not mature enough to tell it like it is,” she said. “You are failing us. But the young people are starting to understand your betrayal.”
