52% Think Earth Is Warming Due to Human Activity

A slim majority of American adults think the earth is getting warmer mostly because of human activity, according to a Pew Research Center survey. The 52 percent majority feel this way. Another 17 percent agree the earth is warming but they think it is mostly because of natural patterns in the environment. A substantial 21 percent are outright deniers: they think there is no solid evidence of global warming.

Young adults are most likely to think the earth is warming because of human activity, while people aged 50 or older are least likely to feel this way.

Percent who say the earth is getting warmer mostly because of human activity
Aged 18 to 29: 69%
Aged 30 to 49: 54%
Aged 50 to 64: 43%
Aged 65-plus: 44%

Among people aged 50 or older, those who believe the earth is warming due to human activity are outnumbered by those who don't believe it is warming, who think warming is due to natural patterns, or who don't know what to think. Greta Thunberg has work to do.
