We are pleased to announce an article published today in Nature Climate Change: "Predictors of public climate change awareness and risk perception around the world."
Our research reveals for the first time what the world thinks about climate change and why. Using data from the 2007-2008 Gallup World Poll, conducted in 119 countries, researchers identified the factors that most influence climate change awareness and risk perception for 90 percent of the world's population.
The contrast between developed and developing countries was striking: In North America, Europe and Japan, more than 90 percent of the public is aware of climate change. But in many developing countries relatively few are aware of the issue, although many do report having observed changes in local weather patterns.
Overall, we found that about 40 percent of adults worldwide have never heard of climate change. This rises to more than 65 percent in some developing countries, like Egypt, Bangladesh and India.Continue reading
We are pleased to announce a newly published article: Simple Messages Help Set the Record Straight about Scientific Agreement on Human-Caused Climate Change: The Results of Two Experiments.
Human-caused climate change is happening; nearly all climate scientists are convinced of this basic fact according to surveys of experts and reviews of the peer-reviewed literature. Yet, among the American public, there is widespread misunderstanding of this scientific consensus. In this paper, we report results from two experiments, conducted with national samples of American adults, that tested messages designed to convey the high level of agreement in the climate science community about human-caused climate change.
We are pleased to announce a new interactive mapping tool called “Yale Climate Opinion Maps” (YCOM) and an accompanying peer-reviewed paper in the journal Nature Climate Change. This tool allows users to visualize and explore differences in public opinion about global warming in the United States in unprecedented geographic detail.
Most of the action to reduce carbon pollution and prepare for climate change impacts is happening at the state and local levels of American society. Yet elected officials, the media, educators, and advocates currently know little about the levels of public and political will for climate action at these sub-national levels. State and local surveys are costly and time-intensive, and as a result most public opinion polling is only done at the national level. This model for the first time reveals the full geographic diversity of public opinion in the United States at these critical levels of decision making.
We are pleased to announce a newly published article: "The Scientific Consensus on Climate Change as a Gateway Belief: Experimental Evidence" by Sander van der Linden, Anthony Leiserowitz, Geoffrey Feinberg and Edward Maibach in the journal PLoS ONE.
Our prior survey research has found that only one in ten Americans (9%) correctly understands that there is a scientific consensus about human-caused climate change – i.e., that nearly all climate scientists are convinced that human-caused climate change is happening. Our new article reports the results of an experiment that investigated how people respond when informed about the scientific consensus.
Our results provide strong evidence for a gateway belief model. On average, being exposed to a “consensus-message” increased study participants’ perceptions of the scientific consensus by 12.8%, and up to as much as 20% in some conditions (compared to a control group). Moreover, this substantial change in the perceived level of scientific consensus caused a positive shift in participants’ belief that climate change is happening, human-caused and a worrisome threat. Changes in these beliefs, in turn, increased support for public action. Importantly, we found these effects for both Democrats and Republicans.Continue reading
We are pleased to announce the publication of a new peer-reviewed article: Howe, P., Boudet, H. Maibach, E., and Leiserowitz, A. (2014) “Mapping the Shadow of Experience of Extreme Weather Events.” Climatic Change 127 (2): 381–89. DOI:10.1007/s10584-014-1253-6.
Climate change will likely increase the frequency and/or intensity of certain extreme weather events, and perceived experience with extreme weather may influence climate change beliefs, attitudes and behaviors.
In this paper we investigated what factors lead people to report experiencing extreme weather events, including their proximity to the event, the size, and the duration of the event. We geographically located each respondent from our 2012 national survey, along with the locations of extreme events from the prior year, including droughts, tornados, and hurricanes. We then mapped the areas in which people reported that they had personally experienced these events, which we call the “shadow of experience.”Continue reading

We are pleased to announce the recent publication of a new peer-reviewed article: Feldman, L., Myers, T., Hmielowski, J., & Leiserowitz, A. (2014). The mutual reinforcement of media selectivity and effects: Testing the reinforcing spirals framework in the context of global warming. Journal of Communication. DOI:10.1111/jcom.12108
Given the diverse sources of news now available in the U.S., partisans can easily choose news sources that align with their political attitudes. Does the rise of partisan news—on cable, talk radio, and the Internet—allow Americans to insulate themselves in “echo chambers” where they are exposed only to content consistent with their opinions, while shielded from dissenting views? If so, this may reinforce partisans’ existing attitudes, making it increasingly difficult for policymakers and the public to achieve mutual understanding and compromise on the most pressing issues of the day, including climate change.Continue reading
The journal Risk Analysis recently published our article "The Role of Emotion in Global Warming Policy Support and Opposition." Prior research has found that affect (feelings of good or bad) and affective imagery (associations) strongly influence public support for global warming. This article extends this literature by exploring the separate influence of discrete emotions, like fear, anger, worry, guilt, etc.
Using a nationally representative survey in the United States, this study found that discrete emotions were stronger predictors of global warming policy support than cultural worldviews (egalitarianism, individualism), negative affect, top of mind associations, or socio-demographic variables, including political party and ideology. In fact, 50% of the variance in public support for global warming policies was explained by the emotion measures alone.
We are pleased to announce a newly published article: "How to Communicate the Scientific Consensus on Climate Change: Plain Facts, Pie Charts or Metaphors?" by Sander van der Linden, Anthony Leiserowitz, Geoffrey Feinberg and Edward W. Maibach in the journal Climatic Change. The article is available for download here.Continue reading
We are pleased to announce our newly published article: "The genesis of climate change activism: from key beliefs to political action" in the journal Climatic Change.
We just published a commentary in Earth’s Future, a new online, open-access journal published by the American Geophysical Union. The commentary is entitled: “Climate Scientists Need to Set the Record Straight: There is a scientific consensus that human-caused climate change is happening.”
In the commentary, we argue that the climate science community needs to do more to communicate the scientific consensus because: (a) most Americans don’t know there is a scientific consensus on this point; (b) this lack of awareness undermines people’s engagement in the issue; and (c) research by our team – and others – has shown that simple messages that communicate this basic scientific conclusion are highly effective, especially with political conservatives.
We encourage you to download the commentary and join the effort to set the record straight.Continue reading
The Arctic is on the front lines of climate change. Average temperatures have warmed 2 to 4 times faster than the rest of the world, permafrost literally melts away before your eyes, and many communities already confront forced relocation. We recently published an article examining climate change in this region in The Journal of Coastal Research entitled Integrating Coastal Vulnerability and Community-based Subsistence Resource Mapping in Northwest Alaska. The paper reports results from a multi-year study done in collaboration with four Inupiaq Eskimo villages on the coast of the Chukchi Sea, north of the Bering Strait.Continue reading

The journal Global Environmental Change recently published an article we wrote examining the accuracy of perceptions about local climate conditions and whether they may be influenced by prior beliefs about the reality of global warming.
We co-authored an original article using our research on public opinion about fracking, published in the journal Energy Policy.
- We conducted a survey of Americans' views on hydraulic fracturing in September 2012
- A majority of Americans have heard little or nothing about hydraulic fracturing.
- Many Americans do not know if they support/oppose it or are undecided.
- Those who have made a decision are evenly split between support and opposition.
- Predictors of support include education, media use and top of mind associations.
Environmental uncertainty is at the core of much of human activity, ranging from daily decisions by individuals to long-term policy planning by governments. Yet, there is little quantitative evidence on the ability of non-expert individuals or populations to forecast climate-related events. Here we report on data from a 90-year old prediction game on a climate related event in Alaska: the Nenana Ice Classic (NIC). Participants in this contest...Continue reading

This study examines climate change coverage on the three major cable news channels and assesses the relationship between viewership of these channels and beliefs about global warming. Evidence from a content analysis of climate change coverage on Fox News, CNN, and MSNBC during 2007 and 2008 demonstrates that Fox takes a more dismissive tone toward climate change than CNN and MSNBC. Fox also interviews a greater ratio of climate change doubters to believers.Continue reading
