This article focused on the study of individual and socialpsychological determinants of a sense of efficacy on climate change mitigation. A correlational study investigated the predictive role of mindfulness, egalitarianism, risk concern, knowledge, and psychological sense of global community (PSGC). An online survey was administrated to US College students (N = 277). The main predictors of climate change response efficacy (CCRE) were PSGC and egalitarianism, followed by risk concern and climate knowledge. Among the facets of mindfulness, observing, and describing were the only ones associated with CCRE. The results found that mindfulness observing predicted response efficacy both directly and through the mediation of risk concern and sense of global community. Conversely, egalitarianism was not a significant mediator. Community psychologists should promote a sense of belonging to all humanity, and a more egalitarian view of the world, beyond risk concern, to increase climate efficacy. Training the skill of mindfulness observing could be a way to produce a sense of global community and affect climate change efficacy.

| INTRODUCTIONClimate change is the major current challenge that humanity is facing given the seriousness and the global scale of its consequences. The reality of the phenomenon and the relationship between human actions and the earth's temperature are seen as incontrovertible truth (IPCC, 2018). The climate has already changed, and some consequences cannot be avoided but we could still prevent worse effects and mitigate damages.This article investigated an integrative model of climate change response efficacy combining for first-time constructs such as mindfulness, risk concern, knowledge, psychological sense of global community, and critical consciousness. Mindfulness was hypothesized to affect efficacy by increasing risk concern and social-psychological variables, that is, sense of global community and egalitarianism.At what extent we believe our commitment can positively interfere with climate change, that is, climate response efficacy is a crucial issue since it affects the use of different response strategies. The perception of what one can do, individually and collectively, is a predictor of specific behaviors such as reducing annual air travel, regulating household energy use, stopping use of aerosol spray cans, talking about global warming with others who do not agree, and voting for candidates devoted to reducing global warming (Bostrom et al., 2019). The direct impact of an individual's daily actions is also relevant in climate change mitigation. Reducing meat consumption, traveling by public transport, bike or foot, choice of alternative energy to heat and cool houses, and preference of local and eco-friendly products have a significant impact on the emission of greenhouse gases that contribute to climat...
