Youth protesters also gathered in locations including Bangkok and Stockholm, where Swedish activist Greta Thunberg joined the school strike - a weekly protest she began as a solitary student in 2018 to call for urgent action to address climate change.
The protests aim to amplify demands for climate action on Earth Day, when people worldwide celebrate and mobilise in support of protecting the environment. They come three weeks after a U.N. climate scientist report warned there is little time left for reining in greenhouse gas emissions sufficiently to prevent the worst impacts of climate change.
Earlier this week, Ipsos MORI released a survey in which two-thirds of around 20,000 people queried in 31 countries on Feb. 18 and March 4 said they were worried about a climate-altered future.
