Tens of thousands of students around the world skipped school school Friday to protest inaction on climate change. It was one of the largest turnouts so far in a months long movement that included the U.S. for the first time, in an event organizers call the "U.S. Youth Climate Strike."

Haven Coleman perched on the steps of the Colorado state capitol in a puffy jacket and hat. The 12-year-old looked tiny against the gray stone columns rising up at her back. With her mom standing nearby, she held up a simple sign. On it, she had written the words “School Strike for Climate” in big black magic-markered letters.

Underneath a blue sign reading “I will vote” in bold white print, 17-year-old Carlos “Carlitos” Rodriguez addressed a crowd in Littleton, Colorado about life since a former student shot and killed 17 of his peers at Marjory Stoneman Douglas High School in Parkland, Florida.
