Climate change protests took over big cities across the country on Friday, with hundreds of thousands skipping school in of Boston, Washington DC, Omaha and Greenborough to join millions around the globe in the lead-up to teenage activist Greta Thunberg's appearance in New York for a summit at the UN.
In New York itself, the city's Department of Education said all its 1.1million schoolchildren can skip class to participate in the strike if they had parental consent - without any fear of punishment as Thunberg, who has been nominated for a Nobel prize for her climate activism, spearheaded a rally at the United Nations headquarters.
Young people held up signs with important messages such as 'don't burn my future'.

As the sea of people made their way through the city, some school students on scooters could be seen heading in the opposite direction, while there was some fighting between protesters and police.
The protests are part of a snowballing movement sparked by school strikes outside the Swedish parliament.
The summit in New York convened by UN secretary general Antonio Guterres to urge countries to up their climate efforts.
Thunberg noted the 'huge crowd' in Sydney in a tweet, which she said would set the standard as the strikes moved across Asia, Europe and Africa.
Protests are planned in some 150 countries on
