More than 5,200 climate strikes will be held in 156 countries around the world from Sept. 20 to Sept. 27, as part of the Global Climate Strike inspired by 16-year-old Swedish climate activist Greta Thunberg, who has .
Thunberg had called for immediate action on climate change on Twitter late on Thursday.
The strike comes after children from the Fridays For Future movement walked out of schools in May to demand action against global warming, asking adults to join them the next time.
Fridays For Future started in 2018 following the call by Thunberg, who protested against the lack of climate action in front of the Swedish parliament every day for three weeks during school hours.
The largest actions are expected to be held in the U.S. and Europe.
Russian organisers said that 27 strikes would be held across the country, including in Kaliningrad, Sochi, Saint Petersburg, and Kirov.
The strike comes ahead of UN Climate Action Summit 2019, which will start in New York on Sept., 23.
