Climate change, a direct result of human activities, such as coal mining, deforestation, fossil fuels' industries, etc., has become the most pressing global challenge of the 21st century. While the environmental impact of climate change is widely recognized, its profound social consequences are equally significant. This chapter delves into the multifaceted consequences of climate change, exploring its effects on vulnerable communities, public health, migration practices, economic disparities, political stability, etc. The chapter then develops the argument that the need to combat climate change and to pay attention to its multifaceted social ramifications should be formulated as a new and separate purpose of the United Nations Organization, among other purposes, such as maintenance of international peace and security, international co-operation to ensure economic and social development, respect, and protection of human rights.
