Gen Z and Millennials both outpace other generations in their climate concern. Majorities of every generation say that they’re at least “somewhat” concerned about climate change, including overwhelming majorities of Gen Z Americans (85%) and Millennials (78%) as well as around three in five Gen X Americans (60%), Baby Boomers (59%), and Americans from the Silent/Greatest generations (63%). Concerns among Gen Z and Millennials are also the most intense: nearly half of Gen Z Americans (49%) and Millennials (47%) say that they’re “very” concerned about climate change, compared to 32% of Gen X, 41% of Baby Boomers, and 34% of the Silent/Greatest generations. Gen Z and Millennials are also relatively more convinced by climate science. Around two-thirds of Gen Z Americans (66%) and Millennials (65%) recognize that climate change is caused mostly by human activity, compared to just under half of Gen X (47%), Baby Boomers (48%), and the Silent/Greatest generations (47%).
