In a recent survey, we ask if there is solid evidence that the Earth has been warming over the past few decades. Seven-in-ten Hispanics say the Earth is warming because of human activity, a higher share than among whites (44%). More than half (56%) of blacks say the same. About two-in-ten Hispanics and whites and a quarter of blacks say the Earth is warming because of natural patterns.
Overall, a quarter of Americans say there is no solid evidence of global warming. Just 11% of Hispanics and 17% of blacks say there is no solid evidence the Earth is getting warmer, while 31% of whites say the same.
The finding about Hispanics comes as the overall share of Americans who say there is evidence of warming has fluctuated over the past decade. In 2006, 77% of U.S. adults said there is solid evidence of global warming. That share dropped to 57% in 2009 before rising to 72% in 2014.
In addition, a significant share of Hispanics say they favor strong action to protect the environment. In a 2014 Pew Research Center survey, respondents were asked to say which statement comes closer to their views: “This country should do whatever it takes to protect the environment” or “This country has gone too far in its efforts to protect the environment.” Three-quarters (76%) of Hispanics chose the first statement, compared with 84% of blacks and 67% of whites.
