Study Suggests Conservatives Who Experience Harm From Extreme Weather More Likely To Support Climate Change Mitigation Policies

People who identify as politically conservative are more like to support climate change mitigation policies if they have report experiencing personal harm from an extreme weather event such as a wildfire, flood or tornado, a new study indicates.

“This study shows how personal harm from extreme weather events may be shifting the beliefs of conservatives,” said Hilary Boudet, an associate professor of public policy in the School of Public Policy in OSU’s College of Liberal Arts and one of the study’s authors. “There’s been a lot of speculation that extreme weather could have this impact. Now we have evidence that personal harm may be moving the needle on a person’s beliefs, particularly those with more conservative political orientations.”

The findings “Personal harm and support for climate change mitigation policies: Evidence from 10 U.S. communities impacted by extreme weather” were just published in the journal Global Environmental Change. The lead author is Chad Zanocco, who worked on the project at a doctoral student in public policy at Oregon State and now is a post-doctoral scholar at Stanford University. Coauthors are Roberta Nilson of Cornell University, a former graduate student in public policy at OSU, and June Flora of Stanford. The research was funded in part by a grant from the National Science Foundation.

Extreme weather events such as fires, floods, tornados, hurricanes and landslides result in some of the most personal impacts of climate change. They are occurring more frequently and with more severity as the climate around the world changes.

Researchers are still working to understand how a person’s individual experience with an extreme weather event shapes their attitudes toward climate change policies. That was a goal of this study, which is part of a larger project examining community reactions to extreme weather in the U.S., Boudet said.

For the study, the researchers surveyed about 1,600 residents of 10 communities across the United States that had experienced extreme weather events with at least four fatalities between 2012 and 2015. They also completed case studies of the disasters and analyzed media coverage in those communities to better understand what kinds of conversations, actions and policies around climate change were occurring in those communities.

The survey included questions about personal harm from the weather event, political ideology, and a suite of questions about climate change-related policy, such as support for renewable energy projects or tax rebates for energy reduction programs. The researchers wanted to understand the link between weather and policy preferences around climate change, rather than just climate change concern or beliefs alone, Boudet said.

Generally liberals in the communities surveyed supported climate change policies, regardless of the level of personal harm they reported from an extreme weather event, Boudet said. But conservatives indicated more support for climate mitigation policy when they also reported experiencing higher levels of harm from an extreme weather event.

The researchers did not ask about the extreme weather events in the context of climate change, indicating that study participants may be identifying the weather events as related to climate change on their own, Boudet said.

“It is also important to note that we considered a range of extreme weather events in this study, such as floods, hurricanes, tornadoes, wildfires and hurricanes, and this relationship between harm and support for climate change mitigation policy held across all event types,” Zanocco said. “This is surprising because some extreme weather events, such as tornadoes, have a relatively low scientific link to climate change.”

Researchers are still working to understand how changes in individual attitudes about climate change might transfer into broader community movements, Boudet said. One of the challenges for researchers and policymakers is navigating the line between capitalizing on changing attitudes to shift behavior and policy while not appearing to exploit a tragedy for seemingly politically-motivated reasons.

Another finding of note, Boudet said, is the alignment between objective measures of a weather event’s harm and people’s self-reported experience of harm from the event. That means that generally, the harm people reported experiencing matched up to the harms reported by other means, including news reports and government records.

One of the study’s limitations, Boudet noted, is that lack of data about participants’ beliefs before the extreme weather event in their community. Additional research is needed to confirm the findings of the study, she said.


A growing body of research examines the role of extreme weather experience—as one of the most personal, visceral (and increasingly frequent and severe) impacts of climate change—in shaping views on climate change. A remaining question is whether the experience of an extreme weather event increases climate change concern via experiential learning or reinforces existing views via motivated reasoning. Building on this work, we explore the relationship between personal experience and climate change policy preferences using surveys in 10 communities that experienced extreme weather events (3 tornadoes, 3 floods, 2 wildfires, 1 hurricane and 1 landslide). We find that self-reported personal harm aligns with objective measures of event impacts and that personal harm (i.e., experience) is associated with higher levels of policy support. However, we do not find that objective measures of event impacts are related to policy support. Though political ideology (i.e., motivated reasoning) dominates our model of policy support in predictable ways, personal harm moderates this relationship suggesting that conservatives reporting higher levels of personal harm from the event are, on average, more likely to express support for climate policy than those reporting lower levels of harm. We postulate that while extreme weather events may serve as teachable moments on climate change, their lessons may only reach conservatives who feel personally harmed, even in the communities most affected.
