Scientists were warning about the risks of climate change and the burning of fossil fuels before today's world leaders were Greta Thunberg's age.
The Swedish 16-year-old, frustrated with the pace of government action to deal with climate change, launched a "school strike for climate" last year. It set off an international youth movement and widespread demonstrations that are drawing attention to the growing risks for their generation as global temperatures continue to rise.
"People always tell us that they are so hopeful. They are hopeful that the young people are going to save the world, but we are not. There is simply not enough time to wait for us to grow up and become the ones in charge," Thunberg told the European Economic Social Committee in one of several speeches she has given to government and business leaders in recent months.
On March 15, students in hundreds of cities in countries around the globe held school strikes calling for action on climate change. These charts show why.
