Global trends in inequality and climate change are closely related. The poorest and most vulnerable individuals suffer the worst effects of climate change while making the smallest contributions to the situation. Millions of people who are vulnerable are being hit disproportionately hard by the effects of climate change, including extreme weather, health issues, food, water, and livelihood security, migration and forced displacement, loss of cultural identity, and other threats. Children, people with disabilities, ethnic minorities, older people, and other socially marginalized groups are some social groups that are particularly vulnerable to crises. Their geographic locations, financial, socioeconomic, cultural, and gender statuses, as well as their access to resources, services, decision-making authority, and justice, are the core reasons of their vulnerability. The paper presents some of the social dimensions of climate change in Viet Nam, including its impacts on migration, various vulnerable subjects, human rights, health, and businesses. Comments, discussions, and suggestions have also been provided in this paper.
