The 19-year-old recently landed in jail for doing just that, in protest at what she believes is the German government’s failure to act against climate change.

Schinkoethe is part of a group called Uprising of the Last Generation that claims the world has only a few years left to turn the wheel around and avoid catastrophic levels of global warming.

Like-minded activists elsewhere in Europe have interrupted major sporting events such as the Tour de France and the Formula One Grand Prix in Silverstone in recent weeks, while others glued themselves to the frame of a painting at London’s Royal Academy of Arts Tuesday. But Schinkoethe’s group has mainly targeted ordinary commuters in cities such as Berlin who, on any given day this summer, might find themselves in an hours-long tailback caused by a handful of activists gluing themselves to the asphalt.

Their actions have prompted outrage and threats from inconvenienced motorists. Tabloid media and some politicians have accused them of sowing chaos and harming ordinary folk just trying to go about their business. Some have branded them dangerous radicals.

Schinkoethe says the escalation in tactics is justified.

“If we wanted people to like us then we’d do something else but we’ve tried everything else,” she told The Associated Press. “We’ve asked nicely. We’ve demonstrated calmly.”

She recalls joining the Fridays for Future protests led by Swedish activist Greta Thunberg which saw hundreds of thousands of students worldwide skip school and rally for a better world.
