"Americans' concern about global warming or climate change remains elevated compared with what it had been prior to 2017," according to Gallup, reporting on its recent poll about attitudes toward climate change. "But acceptance, concern, and attribution continue to be highly politicized: "Most Americans believe global warming is occurring, express at least a fair amount of concern about it, and believe it is caused by human activities, but Republicans take opposing views on the matter."
Asked "And from what you have heard or read, do you believe increases in the Earth's temperature over the last century are due more to the effects of pollution from human activities or natural changes in the environment that are not due to human activities?" 64% of respondents chose the human activities response and 34% chose the natural changes response, with 3% expressing no opinion. The human activities response was preferred by 90% of Democrats, 65% of independents, and 28% of Republicans.
According (PDF) to Gallup's report, the poll was conducted by telephone interviews conducted March 2-18, 2026, with a random sample of 1000 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia; the sample was weighted to correct for unequal selection probability, nonresponse, and double coverage of landline and cell users in the two sampling frames, and to match national demographics. The maximum margin of sampling error for the total sample was +/- 4 percentage points at the 95% confidence level.
