Similar protests, inspired by 16-year-old Swedish activist Greta Thunberg, are planned in some 150 countries on Friday. The strike will culminate in New York when Thunberg, who has been nominated for a Nobel prize for her climate activism, will spearhead a rally at home of the United Nations headquarters.
