In March this year, more than 1.4 million students and school children followed her example and took part in a worldwide protest to demand action from leaders. Just two months later, on 24 May, another protest took place as hundreds of thousands of young people from 110 countries refused to go to class, and instead marched on the streets of their cities, demanding change.

Some have been met with resistance. When high school students graduate in the US, a valedictorian usually gives a speech at the official ceremony. This year, the youth-led movement Class of 0000 organised a campaign which encouraged students to include a text on ‘catastrophic climate change’ in their speeches.

More than 350 young people had pledged to take part, and ask world leaders to “have plan to get to zero emissions, or get zero of our votes”.
