Enduring Extremes? Polar Vortex, Drought, and Climate Change Beliefs

Weather, Climate, and Society, 2013

A series of polls provides new tests for how weather influences public beliefs about climate change. Statewide data from 5,000 random-sample telephone interviews conducted on 99 days over two and a half years (2010 to 2012) are merged with temperature and precipitation indicators derived from USHCN station records. The surveys carry a question designed around scientific consensus statements that climate change is happening now, caused mainly by human activities. Alternatively, respondents can state that climate change is not happening, or that it is happening but mainly for natural reasons. Belief that humans are changing the climate is predicted by temperature anomalies on the interview and previous day, controlling for season, urvey and individual characteristics. Temperature effects concentrate among one subgroup, owever: individuals who identify themselves as Independent, rather than aligned with a olitical party. Interviewed on unseasonably warm days, Independents tend to agree with the cientific consensus regarding anthropogenic climate change. On unseasonably cool days, they tend not to. Although temperature effects are sharpest for just a 2-day window, we see positive effects for longer windows as well. As future climate change shifts the distribution of anomalis and extremes, this will first affect beliefs among unaligned voters.

This paper analyzes the changes Americans perceive to be taking place in their local weather and tests a series of hypotheses about why they hold these perceptions. Using data from annual nationwide surveys of the American public taken from 2008 to 2011, coupled with geographically specific measures of temperature and precipitation changes over that same period, the authors evaluate the relationship between perceptions of weather changes and actual changes in local weather. In addition, the survey data include measures of individual-level characteristics (age, education level, gender, and income) as well as cultural worldview and political ideology. Rival hypotheses about the origins of Americans’ perceptions of weather change are tested, and it is found that actual weather changes are less predictive of perceived changes in local temperatures, but better predictors of perceived flooding and droughts. Cultural biases and political ideology also shape perceptions of changes in local ...

I use one nationally representative sample from CBS News/New York Times Poll on Environment (2007), supplemented with monthly temperature and precipitation data from the United States Historical Climatology Network and extreme weather events data from National Climatic Data Center, to examine how different weather measures and individuals’ socio-demographic background, political predisposition, and beliefs about global warming affect the perception of local weather. Beliefs about global warming are found to play a dominant role in determining the perception of local weather. Specifically, people who view that global warming is causing an immediate impact, is serious, and needs to be a priority are much more likely to perceive a strange pattern of weather in the recent past. This finding conforms to motivated reasoning which refers to the tendency to interpret evidence to confirm the pre-existing beliefs and predisposition. Among all the weather measures, the total number of extreme weather events in the past three years appears to be the only significant indicator of perceived weather. Specifically, individuals who have experienced more extreme weather events in their home counties are more likely than those elsewhere to perceive the weather is stranger than usual. I further examine how actual weather and perceived weather together affect perceptions of global warming. The results illustrate that the perception of local weather has stronger explanatory power than actual weather. People who perceive the strange weather patterns are much more likely than others to see the immediate impacts and priority of global warming. Future studies are needed to investigate the dynamic relationship between perceptions of global warming and perceptions of weather and climate. In addition, more studies are needed to further examine how the public forms their opinions toward various specific types of the local weather and climate.

Existing literature on climate change beliefs in the US suggests that partisan polarization begets climate change polarization and that the climate beliefs of those on both sides of the partisan divide are firmly held and invariable. Here, we use data from a large panel survey of Oklahoma residents administered quarterly from 2014 through 2018 to challenge this perspective. Contrary to the expectation of rough symmetry in partisan polarization on climate change, we find that partisans on the political right have much more unstable beliefs about climate change than partisans on the left. An important implication is that if climate beliefs are well anchored on the left, but less so on the right, the latter are more susceptible to change. We interpret this to suggest that, despite polarizing elite rhetoric, public beliefs about climate change maintain the potential to shift towards broader acceptance and a perceived need for action.

Objective. To explore the effects of long-term climate trends and short-term weather fluctuations, evaluations of scientists and science, political predispositions, religious affiliation, the information environment, and demographic attributes on individuals' views about whether global warming exists and, if so, whether it is a result of natural cycles or human activity. Methods. We use data from the 2009 Pew General Public Science Survey, along with data on long-and short-term patterns of temperature and precipitation in individuals' home communities. Results. We find that long-term trends in summer temperatures influence perceptions of global warming. Individuals who reside in communities with long-term warming of summer temperatures that are coupled with long-term cooling of spring temperatures are significantly more likely to perceive that global warming exists and is due to human activity. We also find that Americans' attitudes toward scientists and science, political dispositions, evangelical religious affiliation, education, and some demographic attributes all have discernible effects on their perceptions of anthropogenic (man-made) global warming. Conclusion. Individuals' attitudes toward global warming are influenced by long-term temperature trends in their home communities, as well as a variety of attitudinal and demographic attributes.

Objectives. In this article we examine the causes of both belief and disbelief in global warming among adult Americans. Methods. We use national-and statelevel telephone surveys to collect data on individual-level beliefs regarding climate change and employ ordered logistical regression to measures the relative effect of various factors on those beliefs. Results. The study finds that U.S. views on climate change are being shaped by a combination of personal observations, meteorological events, and physical changes on the planet. The impact of various factors on one's belief in global warming are significantly determined by partisan affiliation, with Democrats and Republicans responding differently to assorted types of evidence. Conclusion. Beliefs regarding global warming are being shaped by individual experiences and weather phenomenon and the processing of such factors is substantially influenced by a person's partisan leanings.

Do temperature anomalies affect political polarization over global warming? Amer-icans' attitudes about global warming are affected by whether they reside in states experiencing unseasonably warm (or cold) temperatures versus those experiencing milder temperatures. Specifically, in terms of causal attribution, political polarization over global warming is more pronounced in states experiencing temperature anomalies. Using pooled data collected during 2013–2014, this study utilizes logistic regression to explore how temperature anomalies exacerbate the political polarization among Americans over perceptions of whether global warming impacts are immediately evident as well as the attribution of global warming to human activity. Results indicate that very cold or warm temperature anomalies from a 5-year baseline predict perceptions of global warming impacts and exacerbate existing political polarization over the causal attribution of global warming. These effects are particularly noticeable among Democrats. This analysis provides a contribution to understanding how temperature anomalies from the recent past shape the sociophysical context of global warming attitudes.

Although perceptions of common weather phenomena moderately align with instrumental measurements of such phenomena 1 , the evidence that weather or climatic conditions influence beliefs about anthropogenic climate change is mixed 2–13. This study addresses both foci, which are important to scholars who investigate human–environment interactions and observers who expect greater exposure to weather or climate extremes to translate into stronger support for climate change adaptive measures and mitigative policies. We analyse the extent to which state-level winter temperature anomalies influence the likelihood of perceiving local winter temperatures to be warmer than usual and attributing these warmer temperatures mainly to global warming. We show that actual temperature anomalies influence perceived warming but not attribution of such warmer-than-usual winter temperatures to global warming. Rather, the latter is influenced more by perceived scientific agreement; beliefs about the current onset, human cause, threat and seriousness of global warming; and political orientation.
