The report finds that 70% of Americans believe global warming is happening, with 59% attributing it primarily to human causes. While 64% express worry and many perceive immediate local risks from extreme weather, social engagement remains low, with 66% rarely or never discussing the issue with family and friends. The study also highlights a gap in understanding scientific consensus, as only 21% recognize that over 90% of climate scientists agree on human-caused warming.

The report finds that while 39% of Americans believe global warming is harming the health of the general population, only 16% feel it harms their own health. There is an increasing awareness of specific health risks, particularly heat stroke, air pollution, and respiratory issues, and a growing recognition that low-income people and people of color are disproportionately affected. Trust in information sources like primary care physicians and climate scientists has risen, while coal and nuclear energy are viewed as the most harmful energy sources to health.

A survey of 890 registered U.S. voters conducted in December 2024 reveals broad support for clean energy development and climate justice policies, though significant political polarization remains regarding the economic impact of the energy transition and specific regulatory measures. While majorities support the Paris Climate Agreement and the Inflation Reduction Act of 2022 (after reading a description), collective efficacy and active political advocacy for climate action remain relatively low.

The report identifies six climate opinion segments in the US: Alarmed, Concerned, Cautious, Disengaged, Doubtful, and Dismissive. As of Fall 2023, 56% of Americans are either Alarmed or Concerned, with the Alarmed segment growing from 15% in 2013 to 28% in 2023. The Cautious segment saw the largest decline over the same period, dropping from 26% to 15%.

The report reviews global research on the intersection of climate change and health, finding that framing climate change as a public health issue—particularly through the use of trusted health professionals and positive, solutions-oriented messaging—can increase public engagement and support for climate policies across political divides. It notes a significant lack of representative data from the Global South and highlights the need for better integration of climate-health curricula in medical education and stronger engagement from public officials.

A survey of 906 registered U.S. voters in October 2023 reveals broad support for clean energy infrastructure and the Inflation Reduction Act, though significant political polarization persists. While majorities support carbon taxes and transitioning to 100% clean energy by 2050, trust in fossil fuel companies remains low, and actual political or consumer activism is limited despite expressed willingness to act.

A 2023 survey of U.S. adults found that 60% prefer a home where all or most major appliances are powered by electricity. Preferences vary by demographics, with the highest support among liberal Democrats (75%) and Black respondents (69%), while rural residents (54%) are less likely to prefer electrification than urban (65%) or suburban (61%) residents.

The report finds that while a majority of Americans (65%) are unfamiliar with the term 'climate justice', over half (53%) support its goals after receiving a brief description. Support is highest among Black (70%) and Hispanic/Latino (66%) adults, who also show the largest gaps between prior awareness and subsequent support. Additionally, 43% of U.S. adults would be more likely to vote for a candidate supporting climate justice, with the strongest likelihood found among Black (62%), urban-dwelling (53%), and Hispanic/Latino (51%) respondents. The authors conclude that there is a significant opportunity to expand the national support base through targeted education and communication, particularly for marginalized groups who are most affected by climate change.

The study finds that 27% of U.S. Republicans are Alarmed or Concerned about global warming. These individuals are more likely to be younger, female, politically moderate, people of color, and suburban residents compared to other Republicans. While they hold stronger pro-climate views and support policies like renewable energy research and carbon dioxide regulation more than the average American, they are no more likely to discuss or hear about climate change in their social circles.

Based on a March 2021 survey of 1,037 U.S. adults, the report finds that 'Weather extremes and changes' is the most commonly cited threat of global warming, mentioned by 20% of respondents. Perceptions of these threats vary significantly by political affiliation, with Democrats more likely to cite extreme weather and inaction, while Republicans are more likely to view climate action itself as a threat or believe global warming is not a threat. Other identified concerns include pollution, environmental harms, and food and water shortages.

The report finds that while only 34% of Americans are familiar with the term 'climate justice', 53% support its goals after reading a description. There is significant political polarization regarding the concept, but broad cross-partisan support for specific policies such as creating green spaces in low-income communities (81%) and training programs for renewable energy jobs (75%).

The report finds that a majority of registered U.S. voters prefer candidates who support action on global warming and support various clean energy policies, including a transition to 100% clean energy by 2050. While there is broad support for the Inflation Reduction Act of 2022 after it is described, awareness of the law remains low. The findings highlight a significant trust deficit toward fossil fuel companies and a general perception that the U.S. government is not responding effectively to climate change. Despite this, actual political and consumer activism remains relatively low, and collective efficacy—the belief that citizens can influence government and corporate action—is limited to less than half of the electorate.

Analysis of survey data from March 2018 to April 2023 shows that Americans are increasingly worried about extreme heat harming their local areas. Concern grew by 9 percentage points over five years, outpacing increases in worry about other climate impacts such as wildfires and droughts. A majority of Americans also recognize the link between global warming and extreme heat.

The study finds that 7% of American adults experience at least mild levels of Climate Change Psychological Distress (CCPD), with Hispanic/Latino adults and younger generations (Gen Z, Millennials, and Gen X) showing the highest rates of anxiety and depression. Approximately 8% of American adults are interested in or already seeking professional counseling to discuss their feelings about global warming, a figure that rises to 21% among Hispanic/Latino respondents.

A survey of 861 registered U.S. voters in Spring 2023 reveals broad support for local climate-friendly infrastructure and energy efficiency programs, though significant political polarization exists regarding national mandates and offshore drilling. While a majority believe corporations and government should do more to address global warming, actual individual political participation remains low, and only 11% of voters believe the U.S. government is responding well to the issue.

The report finds that a strong majority of Americans believe global warming is occurring and is mostly human-caused, with 66% expressing worry about the issue. While many perceive significant risks to their local communities and the United States—particularly from extreme heat, sea level rise, and wildfires—most Americans rarely discuss the topic with friends and family. The findings also indicate a general rejection of fatalism, with 66% disagreeing that it is too late to act, although a significant gap remains in public understanding of the strength of the scientific consensus on human-caused warming.

The analysis finds that a majority of Americans rarely or never discuss global warming, with the highest rates of conversation occurring among Democrats, educated urban residents, Gen Z and Millennials, and Hispanic/Latino Americans. The study highlights a strong correlation between talking about climate change and being in the 'Alarmed' category of the Global Warming’s Six Americas framework, as well as the influence of supportive social norms and frequent exposure to climate discussions in social circles and the media.

The analysis finds that younger generations, women, and people of color—particularly women of color—are more likely to be 'Alarmed' or 'Concerned' about global warming, while White adults are more likely to be 'Doubtful' or 'Dismissive'.

The report finds that while a majority of Americans (57%) have heard little or nothing about the Inflation Reduction Act (IRA), 68% of registered voters support it after learning about its goals. Support is particularly high among Black Americans (78%), Gen Z/Millennials (78%), and women (75%), groups that were also among the least familiar with the law. Politically, support is strongest among liberal Democrats (97%) and moderate/conservative Democrats (91%), while conservative Republicans are the least supportive (23%) despite having relatively high initial awareness.

The document details the 'Global Warming’s Six Americas' framework, which categorizes the U.S. public into Alarmed, Concerned, Cautious, Disengaged, Doubtful, and Dismissive segments based on their beliefs and motivations regarding climate change. As of December 2022, 26% of Americans are Alarmed and 27% are Concerned, meaning a majority (53%) are either Alarmed or Concerned. Over the decade since 2012, the Alarmed segment more than doubled from 12% to 26%, while the Cautious segment decreased from 29% to 17%. The report links the growth of the Alarmed segment to an increased public understanding that global warming is a present-day problem causing harm within the United States.
