Policy-Instrument Choice and Benefit Estimates for Climate-Change Policy in the United States
This paper provides the first willingness-to-pay (WTP) estimates in support of a national climate-change policy that are comparable with the costs of actual legislative efforts in the U.S. Congress. Based on a survey of 2,034 American adults, we find that households are, on average, willing to pay between 89 per year in support of reducing domestic greenhouse-gas (GHG) emissions 17 percent by 2020. Even very conservative estimates yield an average WTP at or above $60 per year. Taking advantage of randomized treatments within the survey valuation question, we find that mean WTP does not vary substantially among the policy instruments of a cap-and-trade program, a carbon tax, or a GHG regulation. But there are differences in the sociodemographic characteristics of those willing to pay across policy instruments. Greater education always increases WTP. Older individuals have a lower WTP for a carbon tax and a GHG regulation, while greater household income increases WTP for these same two policy instruments. Republicans, along with those indicating no political party affiliation, have a significantly lower WTP regardless of the policy instrument. But many of these differences are no longer evident after controlling for respondent opinions about whether global warming is actually happening.
Americans’ Global Warming Beliefs and Attitudes
This report presents results from a national study of what Americans understand about how the climate system works, and the causes, impacts, and potential solutions to global warming. Among other findings, the study identifies a number of important gaps in public knowledge and common misconceptions about climate change.

Climate Change in the Latino Mind
This report focuses on a critical demographic in the United States – Latinos. Currently 17% of the U.S. population (more than 58 million people) and the second-largest racial/ethnic group in the nation, Latinos are a fast-growing demographic projected to reach 24% of the population by 2065, while non-Latino whites will decrease from 62% of the current population to 46% in 2065. A 2017 nationally representative survey of 2,054 English and Spanish-speaking Latinos investigates their current climate change knowledge, risk perceptions, policy support, behaviors, motivations, and barriers to political action

Willingness to Pay and Political Support for a U.S. National Clean Energy Standard
In 2010 and 2011, Republicans and Democrats proposed mandating clean power generation in the electricity sector. To evaluate public support for a national clean energy standard (NCES), we conducted a nationally representative survey that included randomized treatments on the sources of eligible power generation and program costs. We find that the average American is willing to pay 128-59 per year, while House passage would require costs below $48 per year. The results imply that an “80% by 2035” NCES could pass both chambers of Congress if it increases electricity rates less than 5% on average
The wisdom of crowds: predicting a weather and climate-related event
types: ArticleArticle published in open-access journal, Judgment and Decision Making, vol. 8(2), pp. 91-105Environmental 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 guess to the nearest
minute when the ice covering the Tanana River will break, signaling the start of spring. Previous research indicates a
strong correlation between the ice breakup dates and regional weather conditions. We study betting decisions between
1955 and 2009. We find the betting distribution closely predicts the outcome of the contest. We also find a significant
correlation between regional temperatures as well as past ice breakups and betting behavior, suggesting that participants
incorporate both climate and historical information into their decision-making
Public Perceptions of the Health Risks of Extreme Heat Across US States, Counties, and Neighborhoods
Extreme heat is the leading weather-related cause of death in the United States. Many individuals, however, fail to perceive this risk, which will be exacerbated by global warming. Given that awareness of one’s physical and social vulnerability is a critical precursor to preparedness for extreme weather events, understanding Americans’ perceptions of heat risk and their geographic variability is essential for promoting adaptive behaviors during heat waves. Using a large original survey dataset of 9,217 respondents, we create and validate a model of Americans’ perceived risk to their health from extreme heat in all 50 US states, 3,142 counties, and 72,429 populated census tracts. States in warm climates (e.g., Texas, Nevada, and Hawaii) have some of the highest heat-risk perceptions, yet states in cooler climates often face greater health risks from heat. Likewise, places with older populations who have increased vulnerability to health effects of heat tend to have lower risk perceptions, putting them at even greater risk since lack of awareness is a barrier to adaptive responses. Poorer neighborhoods and those with larger minority populations generally have higher risk perceptions than wealthier neighborhoods with more white residents, consistent with vulnerability differences across these populations. Comprehensive models of extreme weather risks, exposure, and effects should take individual perceptions, which motivate behavior, into account. Understanding risk perceptions at fine spatial scales can also support targeting of communication and education initiatives to where heat adaptation efforts are most needed
The Influence of Political Ideology and Socioeconomic Vulnerability on Perceived Health Risks of Heat Waves in the Context of Climate Change
Vulnerability and resilience to extreme weather hazards are a function of diverse physical, social, and psychological factors. Previous research has focused on individual factors that influence public perceptions of hazards, such as politics, ideology, and cultural worldviews, as well as on socioeconomic and demographic factors that affect geographically based vulnerability, environmental justice, and community resilience. Few studies have investigated individual socioeconomic and racial/ethnic differences in public risk perceptions of the health hazards associated with extreme heat events, which are now increasing due to climate change. This study uses multilevel statistical modeling to investigate individual- and geographic-level (e.g., census tract level and regional) social, economic, and biophysical influences on public perceptions of the adverse health impacts associated with heat waves. Political orientation and climate change beliefs are the strongest predictors of heat wave health risk perceptions; household income also has a relatively strong and consistent effect. Contextual socioeconomic vulnerability, measured with a social vulnerability index at the census tract level, also significantly affects heat wave risk perceptions. The strong influence of political orientation and climate beliefs on perceptions of adverse health impacts from heat waves suggests that ideological predispositions can increase vulnerability to climate change
