The Alliance for Climate Education seeks to educate young people on the science of climate change and empower them to take action. Millennials are the largest generation in the country, representing more than one quarter of the total population; they also care more about climate change than any other group in the U.S. Compared to the general population, 70% of people ages 13-25 agree that climate change is real and the result of human activity. ACE engages with young people nationwide and, in particular, with key communities that face the greatest climate impacts, have active anti-science education policies in place, and possess the highest potential for meaningful influence from increased youth civic engagement. Since 2008, ACE has brought climate science education to more than 2 million students, supported young people to take more than 700,000 actions, and trained over 4,000 youth to become climate leaders in their communities. Empowered with education, tools, and confidence, young people have the potential to elevate climate change as a national priority, create equitable solutions to the climate crisis, and become leaders in the climate justice movement.
