Nurturing care as a critical buffer against climate change impacts on child development.

We examine empirical and conceptual considerations related to the role of nurturing care for protecting human capital formation in the context of climate change. Climate change is a pressing global challenge. Heatwaves, wildfires, storms, and floods are becoming more frequent and severe, and their direct impact and aftermath can have long-lasting negative effects on employment, education, healthcare, and access to essential services. Children are particularly vulnerable to these harms due to their developmental immaturity and limited capacity to mitigate and avoid risks [1,2]. Consequently, parents and other adult primary caregivers - such as grandparents, relatives, and foster parents (hereafter "caregivers") - provide the primary buffer between climate hazards and adverse developmental outcomes. They do this through nurturing care, defined as the provision of stable environments that promote children's health and nutrition, safety and security, opportunities for learning, and emotionally supportive relationships [3]. Despite the central role of nurturing care for children's life outcomes, it rarely appears in climate change research and policy discourse.
