The Interplay Between Climate Change Exposure, Awareness, Coping, and Anxiety Among Individuals with and Without a Chronic Illness

Climate change poses a significant threat to mental health, including the emergence of climate change anxiety (CCA). In this study, we examined whether exposure to climate-related events was associated with higher CCA through the mediating roles of climate change awareness and ecological coping strategies and whether these pathways differed by chronic illness status. In February 2025, 600 Israeli adults (50% female; mean age ≈ 50) completed an online self-report questionnaire assessing climate change exposure, awareness, coping, and anxiety. Data were analyzed using moderated mediation models, controlling for gender, age, and education. Greater climate change exposure was associated with an increased awareness and higher use of problem-focused coping, which, in turn, predicted elevated CCA. Meaning-focused coping was not associated with anxiety overall; however, among the participants without a chronic illness, it was linked to higher CCA. Climate change awareness alone was not associated with anxiety. A significant serial mediation was found via awareness and problem-focused coping, and a moderated mediation was found via meaning-focused coping among those without a chronic illness. Coping strategies play a key role in climate change anxiety. Although health status may influence this process, tailored interventions should prioritize coping styles in climate adaptation efforts.
