Swedish climate activist Greta Thunberg met with a president during her visit to Washington, DC, on Monday—but not the one currently in office. Instead, she met with former President Obama, who later praised her in a tweet, the Hill reports. At 16, Greta is "already one of our planet’s greatest advocates," Obama wrote. "Recognizing that her generation will bear the brunt of climate change, she’s unafraid to push for real action." Greta and a group of other young activists also met with the Senate's climate crisis task force Tuesday, the Guardian reports. "Please save your praise. We don't want it," she said. "Don’t invite us here to just tell us how inspiring we are without actually doing anything about it because it doesn’t lead to anything."
"If you want advice for what you should do, invite scientists, ask scientists for their expertise," she continued. "We don’t want to be heard. We want the science to be heard." She told lawmakers: "I know you are trying but just not hard enough. Sorry." Democratic Sen. Ed Markey, leader of the climate task force, praised Greta anyway, describing her as a "superpower," the BBC reports. "We need your leadership," he told her. Greta is due to address Congress on Wednesday and will support nationwide school strikes to protest the lack of action on climate change Friday. She says there will be 4,638 events in 139 countries.
