As described in section 3.1, 64% of Americans are at least “somewhat worried” about global warming (this percentage has ranged from about 61% to 70% over the last few years). However, most Americans underestimate how worried the American public is about global warming.Respondents were asked: “To the best of your knowledge, what percentage of adults in the United States (18 years or older) are worried about global warming?” They estimated the percentage by moving a slider bar that appeared on the screen of their computer. This slider allowed respondents to move the marker from 0% on the left to 100% on the right, or to any whole number between the two. A “don’t know enough to say” response option appeared below the slider bar. Only 8% of Americans accurately estimate the percentage of Americans who are worried about global warming. A majority of Americans (61%) underestimate this percentage and an additional 24% indicate that they “don’t know enough to say.” In contrast, only 7% overestimate the percentage of Americans who are worried about global warming.
3.3 A majority of Americans are “interested” in global warming.
When asked how strongly they feel various emotions when thinking about global warming, more than half of Americans (57%) say they feel “very” or “moderately” interested. Additionally, many say they feel sad (48%), afraid (45%; 6 percentage points higher than when we last asked this question in Spring 2025; refer to data tables, p. 52), angry (42%), hopeless (40%; +6 percentage points from Spring 2025; refer to data tables, p. 53), or hopeful (37%).
