Socioecological crises, such as the climate crisis, place a heavy burden on young and future generations. However, these generations have less influence on political and economic decisions. Older generations will be less affected by most socioecological crises but have a greater impact in terms of contribution and resolution. Therefore, young and future generations depend on older generations to act in solidarity. In a preregistered online survey study, we examined the political solidarity of older adults with young people in three countries (US, N = 399; Germany, N = 401; and Brazil, N = 403). Results show that affinity with young people and legacy motivation directly explained intergenerational political solidarity in all three countries. In the US and Brazil, quantity and quality of intergenerational contact with young people indirectly explained political solidarity through affinity. These findings suggest that increasing the closeness between generations may be a promising lever for intergenerational solidarity.

The present study examined the overall potential that the COVID-19 pandemic and its restrictions have for the promotion of climate-friendly food consumption in Germany. We looked at COVID-19-related changes in people’s climate-friendly food-consumption behaviors by comparing retrospectively self-reported performances between the time period in which the COVID-19 restrictions were in place and the pre-COVID-19 period. Furthermore, we examined the durability of such COVID-19-related changes with regard to an imagined post-COVID-19 period and the role of people’s personal climate-protection norms in COVID-19-related behavioral changes. To do so, we conducted two online surveys in June/July 2020 with German consumers: (a) an online study in a sample that was representative of the German population (NCOR1 = 3092) and (b) another online study in a smaller sample of German consumers (NCOR2 = 300). Altogether, the data from both surveys indicated several COVID-19-related changes toward more climate-friendly food consumption, not only during the COVID-19 pandemic and its restrictions, but also with regard to long-term changes in a potential post-COVID-19 period. Furthermore, our results also provide initial empirical evidence that people’s personal climate-protection norms are relevant moderating factors of these short- and long-term COVID-19-related behavioral changes.

Individuals can support climate-change mitigation in many ways, e.g., through private-sphere behaviors or the support of political measures. We assume that the common climate-change-mitigation heuristic of restriction does not sufficiently support impactful mitigation intentions and therefore introduce and investigate a new heuristic (optimization heuristic.) In a cross-sectional survey with N = 1427 participants (representative of the German population with regard to age, gender, education), we developed two scales to measure the heuristics of restriction and optimization. As individual climate-change-mitigation intentions, we recorded four types of private-sphere behavior, activism, and three forms of policy support. Further psychological variables (personal norm, biospheric value orientation) and sociodemographic variables were recorded. The factorial structure of all concepts was assessed by means of confirmatory factor analyses. Hierarchical regression analyses with the climate-change-mitigation intentions as the criterion were carried out. Results support the assumption of two related, yet distinct, climate-change-mitigation heuristics that were highly correlated with biospheric value orientation. We additionally computed measure of the dominance of the restriction heuristic. This variable had no correlation with biospheric values, and correlated with the intentions in the expected ways, indicating that individuals with a dominant restriction heuristic tend to show lower scores of impactful climate-change-mitigation intentions.

The climate crisis poses a major threat for sustainability, with the young and future generations likely to be among the most affected groups in the climate crisis. Older generations will be less affected but have a greater impact both in terms of contribution and mitigation. We investigated potential intergenerational drivers of older Germans’ climate protection intentions and behavior in two pre-registered studies (N₁ = 411, 55- to 75-year olds; N₂ = 309, 55- to 86-year olds). On a correlational level, both studies revealed that contact between generations (particularly high-quality contact) indirectly explained the participants’ climate protection intentions/behavior. This effect was mediated by affinity with younger people (Study 1) and its subfacets of perspective taking and empathic concern (but not the subfacet of perceived oneness; Study 2). Study 1 further provided evidence that legacy motivation, i.e., the desire to leave behind a positive legacy, was positively related to participants’ climate protection intentions and behavior. Study 2’s attempt at testing the causal role of the subfacets of affinity was not successful, as the experimental manipulation of perspective taking toward younger people failed. However, the two studies provide correlational evidence that the closer older people feel to younger people and the future consequences of their behaviors, the more willing they are to protect the climate.

Background: In crises, it is of great relevance to identify mechanisms that help people to maintain a certain level of wellbeing. This paper investigates whether appraising the COVID-19 pandemic as a threat vs. as a challenge has different effects on subjective wellbeing during the pandemic. Furthermore, we study the role of the perceived local environmental quality for individuals' subjective wellbeing.Methods: Via online survey study with two times of measurement (N = 758), we investigated (a) the prediction of participants' wellbeing in June 2020 and June 2021 through five variables and (b) how these five variables moderated within-participant differences in subjective wellbeing over time.Results: Results showed that a stronger perception of the pandemic as a threat (feeling worried) and a lower education in June 2020 predicted a lower subjective wellbeing in 2020 and 2021. A stronger challenge appraisal (feeling confident), higher efficacy expectations, and positive perceptions of the local environmental quality in June 2020 predicted a higher wellbeing in 2020 and 2021. There was no substantial change in participants' aggregated wellbeing over time. However, those who perceived the pandemic more as a threat in June 2020 struggled more with negative changes in their wellbeing, whereas those who perceived the pandemic more as a challenge reported a higher wellbeing.Conclusion: It seems key to support people in activating positive feelings to successfully cope with crises.
