Greta Thunberg, the activist who has quickly become a leading voice on climate change, is Time's Person of the Year for 2019. At 16, she is the youngest person to earn the title in the magazine's 92-year history.
Thunberg burst onto the world stage in the past year, organizing school strikes and protest marches to call attention to a climate crisis that she says older generations are not taking seriously enough. She has famously called out world leaders for debating scientific facts and failing to stop a global warming trend.
Reacting to the honor, Thunberg said she is "a bit surprised" to get chosen, according to The Associated Press, which adds that Thunberg dedicated her recognition to other young activists. Thunberg is currently in Madrid, where she delivered a speech at a U.N. climate conference on Wednesday morning.
