In the US, adults under 40 are considerably more likely than their elders to express concern about the issue and attribute it to human activity. Overall, two-thirds of U.S. younger adults say global climate change is an extremely or very serious problem, compared with roughly half of those ages 40 and older (52%), according to a recent Pew Research Center survey. There are similar age gaps among evangelical Protestants, even though both younger and older evangelicals are less likely than Americans overall to express concern about climate change. Evangelical Protestants under 40 are more likely than older evangelicals to say climate change is an extremely or very serious problem (41% vs. 31%). And 42% of evangelical adults under 40 say the Earth is warming due to human activity, compared with 28% of evangelicals ages 40 and older. However, just 5% of U.S. adults under 40 are both highly religious and concerned about climate change, compared with 9% of those ages 40 and older.
