Young Swedish climate activist Greta Thunberg is continuing her tour of speaking truth to power. Last December, she accused the delegates to the U.N. climate talks in Poland of “stealing” their children’s futures. And on Friday, at the World Economic Forum annual meeting in Davos, Switzerland, she delivered another powerful speech, calling for quick and bold progress on climate change.

“At places like Davos, people like to tell success stories,” Thunberg told the audience. “But their financial success has come with an unthinkable price tag.”

Climate change became a hot topic of discussion at the 2019 meeting of the global elite. Sixteen-year-old Thunberg joined the ranks of Prince William and British naturalist and TV personality Sir David Attenborough, who also urged decisive action on climate change. National leaders, like Japanese Prime Minister Shinzo Abe, unveiled plans and goals for tackling warming at the forum.

Although Thunberg’s message was dire, she stopped short of saying the world is doomed. “Yes, we are failing, but there is still time to turn everything around — we can still fix this,” Thunberg said. “I want you to act as if the house was on fire. Because it is.”
