Fridays for Future strikers around the world shared their demands for bold climate action online Friday as many youth activists heeded public health experts' recommendations in the face of the coronavirus pandemic by eschewing public protests in favor of digital demonstrations.

The online displays followed the call earlier this week from school strike for climate pioneer Greta Thunberg to #ClimateStrikeOnline.

In a Friday tweet as Thunberg marked her 82nd week of school strikes, she reiterated the basis for her call.

"In a crisis we change our behaviour and adapt to the new circumstances for the greater good of society," she wrote.

School strike week 82. In a crisis we change our behaviour and adapt to the new circumstances for the greater good of society.

"I think what is happening in society with the #coronavirus is a glimpse into the future of climate change," wrote New York City-based Fridays for Future organizer Alexandria Villaseñor in Twitter thread Thursday. "We activists have a lot to learn from this moment."

"This is more than a health crisis, this is a crisis about feeling safe in so many ways," Villaseñor added. "The rapidly changing news is causing so much anxiety. Let's be here for each other."
