After 251 weeks, Greta Thunberg announces on Twitter that she will take to the streets for the last time for the climate instead of sitting in class. Since the now 20-year-old is graduating from school, there will be no more protest actions for her instead of classes.

"Fridays For Future" activists are also active in Germany – in the future probably without a figurehead, writes Thunburg. She never expected that her small school strike five years ago would have any effect, let alone start a global movement.
