Over the past 8 months, the International Society for Social Pediatrics and Child Health (ISSOP), has presented a series of symposia on mitigating the impact of the climate crisis on children and youth. The multidisciplinary speakers from around the world, including youth, provided a clear and consistent message—there is little hope for a solution without a radical transformation of society, which must begin today. Youth delivered a poignant message, a plea that continues to resonate. The role they suggested that professional child health organizations can play is to provide them a platform to support their efforts, and access to the decision-makers who can make the changes necessary to mitigate the crisis. They didn’t ask us to craft the message, but to help them deliver it.
