Greta Thunberg's Graduation and Final School Strike for Climate

Greta Thunberg participated in her last School Strike for Climate to mark her graduation from high school on Friday. The 20-year-old previously took a year-long "sabbatical" from school in 2019 to raise awareness for climate action. Thunberg began the School Strike for Climate movement when she sat down, alone, outside the Swedish parliament to demand tougher action on climate change in 2018. She has since become a figurehead for climate action, being invited to address leaders at United Nations conferences, becoming Time magazine's youngest-ever Person of the Year in 2019, and receiving several nominations for the Nobel Peace Prize.
