Resource Type: Polling & Surveys

Since 2008, the National Surveys on Energy and the Environment (NSEE) have been exploring views of global warming among American adults. In the 24th wave of the survey, NSEE reached five key findings:

American acceptance of global warming is at a record high, with 75% of adults believing there is solid evidence that temperatures have increased over the last four decades;
Americans are more confident in their view that the planet is warming, with 51% indicating they are very confident global warming is happening;
Nearly 6 in 10 adults indicated that there is strong evidence of global warming and that humans are partially responsible;  
Almost half – 47% – of Americans attributed 2020’s record warmth to human induced global warming;
Action on climate change is more varied among respondents: mitigation efforts are the most commonly identified climate policies (39%), and nearly equal portions of respondents prioritized adaptation (16%) and geoengineering (17%).

More Americans are alarmed about climate change. Survey research identified six unique audiences within the American public that each responds to the issue of climate change in their own distinct way: alarmed, concerned, cautious, disengaged, doubtful, and dismissive. Between 2014 and 2020, the percentage of the population that is alarmed by climate change more than doubled and by April of 2020 over half of all American adults were in one of the two most worried segments – alarmed (25%) and concerned (28%).
