A record August 2018 heat wave in her home country inspired Thunberg to protest outside parliament, urging her leaders to live up to the promises they made when they signed on to the Paris climate accord. A year later, she’s still protesting.

She’s in front of parliament every Friday—unless she’s boating around the world to give political leaders a dressing-down in person. Her dedication to climate change has turned her into a leader of a growing grassroots movement.
