Climate awareness is widespread in many regions, but it is not uniform. Survey results show substantial differences in whether people have heard of climate change, how they interpret its causes, which impacts they notice, and whether concern translates into action. The figures below distinguish global, regional, national, and subgroup results and retain each survey’s measurement period.

How widespread awareness and concern are
The long-running global picture has changed, but older estimates remain useful for showing how uneven awareness once was. In the 2007–2008 Gallup World Poll, about 40% of adults worldwide had never heard of climate change. Awareness was much higher in North America, Europe, and Japan, where more than 90% of people had heard of it. These figures come from the analysis Climate Change Awareness and Concern in 119 Countries by the Yale Program on Climate Change Communication; they describe that earlier measurement period, not a current global estimate.

More recent results indicate that climate change is a recurring concern for many people globally. In the 2024 People’s Climate Vote, 53% of people worldwide said they were more worried about climate change than they had been the previous year, while 56% said they thought about climate change daily or weekly. The survey also found that 43% thought extreme weather events were worse than the previous year. The Peoples’ Climate Vote 2024
The European Union and United States show high concern in their respective surveys, although these results should not be treated as directly interchangeable. In the European Commission’s 2025 survey, 85% of EU citizens considered climate change a serious problem for the world. In Yale’s nationally representative U.S. survey conducted April 25–May 4, 2024, 70% of U.S. adults said global warming is happening. In the same U.S. survey, 64% said they were at least somewhat worried about it.
| Measure | Geography | Result | Measurement period |
|---|---|---|---|
| Thought about climate change daily or weekly | Global | 56% | 2024 |
| More worried than the previous year | Global | 53% | 2024 |
| Considered climate change a serious problem | European Union | 85% | 2025 |
| Said global warming is happening | United States | 70% | Apr. 25–May 4, 2024 |
| Said they were at least somewhat worried | United States | 64% | Apr. 25–May 4, 2024 |
What people understand about climate change
Awareness does not automatically mean accurate understanding. In the United States, 59% of adults in Yale’s April 25–May 4, 2024 survey said global warming is mostly caused by human activities. Yet only 21% correctly understood that more than 90% of climate scientists think human-caused global warming is happening. The gap shows why climate awareness includes both recognition of the issue and knowledge about its scientific consensus.
U.S. adults most often described global warming as an environmental issue: 77% selected that description. The issue was also viewed as scientific by 68% and as a health issue by 59%. These categories can overlap; the results indicate that people connect climate change with several types of public concern rather than seeing it through only one lens.

Education is associated with large differences in reported climate awareness and belief in India. In 2024, 56% of Indians who were not literate said they had never heard of global warming, compared with 7% of Indians with a college degree or higher. After receiving a definition, 61% of the not-literate group thought global warming is happening, compared with 92% of people with a college degree or higher.
The same Indian study found a difference in attribution. Seventy-two percent of Indians with a college degree or higher said global warming is caused primarily by human activities, compared with 53% of Indians with a high school diploma. The results are education-group findings from 2024 and should not be read as a complete description of every Indian adult. How global warming beliefs differ by education levels in India
Which impacts and risks people perceive
People do not assess climate risk only at a global scale. In the United States, 47% of adults said people in the country are being harmed by global warming right now, and 50% said they had personally experienced its effects. Looking ahead, 65% thought global warming would harm people in the United States, while 52% expected harm to people in their community, 49% to their family, and 44% to themselves personally.
The same survey showed higher concern for some groups and living systems. Seventy-two percent thought global warming would harm plant and animal species, and the same share expected harm to future generations of people. Sixty-nine percent thought the world’s poor would be harmed, while 68% thought people in developing countries would be harmed.
Weather is a particularly visible way that people connect climate change with lived experience. Sixty-six percent of U.S. adults said global warming is affecting weather in the United States, and 56% saw extreme weather as at least a moderate risk to their community over the next 10 years. Globally, 78% of respondents in the 2024 People’s Climate Vote wanted more protection for people at risk from extreme weather.
Heat is also a prominent concern in India. In the 2024 education-level study, 85% of Indians were very or somewhat worried about severe heat waves. This is a measure of worry, not a forecast of future heat exposure, and it should be interpreted within the survey’s national context.
Emotion, discussion, and personal agency
Climate awareness often carries an emotional response. In Yale’s U.S. survey from April 25–May 4, 2024, 58% of adults said they felt interested when thinking about global warming, 49% felt frustrated, and 44% felt hopeful. Overall, 64% were at least somewhat worried. These responses are not mutually exclusive: one person may feel interest, frustration, hope, and worry at the same time.
Personal importance and responsibility were also common. Sixty-seven percent of U.S. adults said global warming is at least somewhat personally important to them, and 62% said they feel a personal sense of responsibility to help reduce it. However, awareness and responsibility do not necessarily lead to frequent conversation or visible collective effort.
Sixty-six percent said they rarely or never discuss global warming with family and friends. Only 41% thought it was at least moderately important to those people that they take action to reduce global warming, and 36% said their family and friends make at least a moderate amount of effort to reduce it.
Information reaches people through several channels, but regular interpersonal discussion is less common than media exposure. Half of U.S. adults said they hear about global warming in the media at least once a month. The comparable figures were 28% for social media and 22% for hearing people they know talk about global warming.
What people want governments and institutions to do
Public support for stronger institutional action is high in the global results. In the 2024 People’s Climate Vote, 80% of people worldwide wanted their governments to take stronger action on the climate crisis, and 86% wanted countries to set aside geopolitical differences and work together on climate change. Eighty percent also supported schools playing a role in increasing climate awareness.
EU respondents expressed broad support for both mitigation and preparation in the European Commission’s 2025 survey. Eighty-one percent supported the EU goal of becoming climate-neutral by 2050. Support reached 88% for greater EU investment in renewable energy and energy efficiency, 84% for more help to European companies competing in clean technologies, and 83% for better preparation for climate impacts. Eighty-five percent said climate action should be a priority for improving public health.
These results describe public preferences, not completed government policies or guaranteed outcomes. They do show that climate awareness is connected to expectations about energy, technology, public health, education, international cooperation, and protection from extreme weather.
Reported actions and information gaps
In the EU’s 2025 survey, 59% of respondents said they had taken an action combating climate change during the previous six months. Among EU respondents who reported climate action, 64% identified reducing and recycling waste as an action they had taken. Because this percentage is calculated among people who reported taking action, it should not be compared directly with the overall 59% figure as if both used the same denominator.
Other reported behaviors included cutting down on disposable items whenever possible, cited by 49% of EU respondents, and considering lower energy consumption when buying a household appliance, cited by 34%. The measures cover different behaviors and do not establish how often, how extensively, or with what environmental effect each action occurred.
Knowledge about causes is relatively strong in the EU result: 84% agreed that climate change is caused by human activity. At the same time, many respondents reported difficulty finding clear and reliable information. Fifty-two percent said traditional media fail to provide clear information about climate change, its causes, and impacts. Forty-nine percent said it is difficult to distinguish reliable climate information from disinformation on social media.
Together, these figures point to an awareness challenge with several parts. Large majorities recognize climate change or support action in many surveyed populations, yet important gaps remain in scientific understanding, local discussion, access to clear information, and the connection between concern and sustained behavior. Effective climate action guides therefore need to explain causes and impacts plainly, identify credible sources, and connect broad public concern with practical choices and institutional responsibilities.
