Investigating similarities and differences in individual reactions to the COVID-19 pandemic and the climate crisis.

How can individuals' responses to the coronavirus disease-19 (COVID-19) pandemic be used to inform constructive responses for climate action? We present an exploratory, mixed-methods investigation (N = 1784 US adults) into similarities and differences in individuals' reactions to COVID-19 and climate change in June 2020. Participants identified many similarities between the issues, indicating that both are harmful to public health, politically polarizing, have global impacts, and have solutions. Participants also perceived many differences between the two threats: many perceived COVID-19 as medical, natural, and on a shorter timescale, while many perceived climate change as environmental, human caused, and on a longer timescale. Emotional reactions to each topic predict topic-relevant behaviors, but more strongly, and with a broader range of emotional reactions, for climate change than COVID-19. Open-ended responses show that hope was elicited for both issues in response to contemplating taking collective and individual actions, and despair was elicited for both issues in response to perceiving that others do not take the issues seriously. Finally, participants perceived that they were engaging in relatively more COVID-19 mitigation behaviors and some climate change mitigation behaviors than others (i.e., the "better-than-average" effect). Many participants believed others were relatively unconcerned about both threats because of the invisibility of the threats, ignorance, and elite cues (e.g., then-President Trump downplaying the threat).

Behavioural frameworks to understand public perceptions of and risk response to carbon dioxide removal.

The adoption of carbon dioxide removal (CDR) technologies at a scale sufficient to draw down carbon emissions will require both individual and collective decisions that happen over time in different locations to enable a massive scale-up. Members of the public and other decision-makers have not yet formed strong attitudes, beliefs and preferences about most of the individual CDR technologies or taken positions on policy mechanisms and tax-payer support for CDR. Much of the current discourse among scientists, policy analysts and policy-makers about CDR implicitly assumes that decision-makers will exhibit unbiased, rational behaviour that weighs the costs and benefits of CDR. In this paper, we review behavioural decision theory and discuss how public reactions to CDR will be different from and more complex than that implied by rational choice theory. Given that people do not form attitudes and opinions in a vacuum, we outline how fundamental social normative principles shape important intergroup, intragroup and social network processes that influence support for or opposition to CDR technologies. We also point to key insights that may help stakeholders craft public outreach strategies that anticipate the nuances of how people evaluate the risks and benefits of CDR approaches. Finally, we outline critical research questions to understand the behavioural components of CDR to plan for an emerging public response.

Shared vision for a decarbonized future energy system in the United States.

How do people envision the future energy system in the United States with respect to using fossil fuels, renewable energy, and nuclear energy? Are there shared policy pathways of achieving a decarbonized energy system? Here, we present results of an online survey (n = 2,429) designed to understand public perceptions of the current and future energy mixes in the United States (i.e., energy sources used for electric power, transportation, industrial, commercial, and residential sectors). We investigate support for decarbonization policies and antidecarbonization policies and the relative importance of climate change as an issue. Surprisingly, we find bipartisan support for a decarbonized energy future. Although there is a shared vision for decarbonization, there are strong partisan differences regarding the policy pathways for getting there. On average, our participants think that climate change is not the most important problem facing the United States today, but they do view climate change as an important issue for the world today and for the United States and the world in the future.

Perceptions of water use.

In a national online survey, 1,020 participants reported their perceptions of water use for household activities. When asked for the most effective strategy they could implement to conserve water in their lives, or what other Americans could do, most participants mentioned curtailment (e.g., taking shorter showers, turning off the water while brushing teeth) rather than efficiency improvements (e.g., replacing toilets, retrofitting washers). This contrasts with expert recommendations. Additionally, some participants are more likely to list curtailment actions for themselves, but list efficiency actions for other Americans. For a sample of 17 activities, participants underestimated water use by a factor of 2 on average, with large underestimates for high water-use activities. An additional ranking task showed poor discrimination of low vs. high embodied water content in food products. High numeracy scores, older age, and male sex were associated with more accurate perceptions of water use. Overall, perception of water use is more accurate than the perception of energy consumption and savings previously reported. Well-designed efforts to improve public understanding of household water use could pay large dividends for behavioral adaptation to temporary or long-term decreases in availability of fresh water.

Paying for what was free: lessons from the New York Times paywall.

In a national online longitudinal survey, participants reported their attitudes and behaviors in response to the recently implemented metered paywall by the New York Times. Previously free online content now requires a digital subscription to access beyond a small free monthly allotment. Participants were surveyed shortly after the paywall was announced and again 11 weeks after it was implemented to understand how they would react and adapt to this change. Most readers planned not to pay and ultimately did not. Instead, they devalued the newspaper, visited its Web site less frequently, and used loopholes, particularly those who thought the paywall would lead to inequality. Results of an experimental justification manipulation revealed that framing the paywall in terms of financial necessity moderately increased support and willingness to pay. Framing the paywall in terms of a profit motive proved to be a noncompelling justification, sharply decreasing both support and willingness to pay. Results suggest that people react negatively to paying for previously free content, but change can be facilitated with compelling justifications that emphasize fairness.

Public perceptions of energy consumption and savings.

In a national online survey, 505 participants reported their perceptions of energy consumption and savings for a variety of household, transportation, and recycling activities. When asked for the most effective strategy they could implement to conserve energy, most participants mentioned curtailment (e.g., turning off lights, driving less) rather than efficiency improvements (e.g., installing more efficient light bulbs and appliances), in contrast to experts' recommendations. For a sample of 15 activities, participants underestimated energy use and savings by a factor of 2.8 on average, with small overestimates for low-energy activities and large underestimates for high-energy activities. Additional estimation and ranking tasks also yielded relatively flat functions for perceived energy use and savings. Across several tasks, participants with higher numeracy scores and stronger proenvironmental attitudes had more accurate perceptions. The serious deficiencies highlighted by these results suggest that well-designed efforts to improve the public's understanding of energy use and savings could pay large dividends.
