Swedish activist Greta Thunberg joined in protests at the White House on Friday, advocating action on climate change, according to NPR.
However, as NPR reported, these protests are just a prelude to the international climate strike that the 16-year-old has planned for the following week on Sept. 20.
Thunberg arrived in the United States on Aug. 24, after a 13-day voyage from the United Kingdom on a zero-emissions sailboat, USA Today reported. The teenager is scheduled to speak at the United Nations’ Climate Action Summit on Sept. 23 in New York City.
According to USA Today, Thunberg joined dozens of protesters at the White House, many of them young people. Protesters chanted, “Hey hey, ho ho, climate change has got to go,” and waved signs that read, “Make Earth cool again,” and, “If you did your job, we would be in school.”
Thunberg has gained worldwide attention for her efforts to combat climate change. She began by skipping school every Friday to protest outside of the Swedish parliament building, according to Reuters.
Now, a little over a year later, Reuters has reported that 3.6 million people from all over the world have joined in on her climate strikes.
The teenager was nominated for a Nobel Peace Prize in March for the work she has done to draw attention to the climate, Reuters says. This work includes giving a TED Talk on taking action against climate change, as well as giving a speech at a U.N. Climate Change Conference in Poland, according to NPR.
Thunberg told NPR that she believes the United States has a “moral responsibility” to lead out on climate change.
“You are such a big country,” she told NPR. “In Sweden, when we demand politicians to do something they say, ‘It doesn’t matter what we do — because just look at the U.S.’”
Thunberg has been organizing an international climate strike for Sept. 20 that has gained widespread attention, encouraging students the world over to walk out of school in protest, according to USA Today.
