Understanding the complex relationship between population and climate change mitigation

The world is currently facing a climate crisis with associated health and plane-tary consequences, and human activity is central to this crisis. Debates on the relationship between population and climate change provide a mixed picture, ranging from demonstrat-ing a clear link between large populous countries and greenhouse gas emissions to pointing to spurious associations between population growth and climate change. We submit that as the interaction between population dynamics and climate change is complex, a nuanced approach to climate mitigation and adaptation strategies is needed. Finding a solution to the climate crisis requires a concerted effort by all nations, whether rich or poor. While there is an urgent need for more industrialized nations to reduce their greenhouse gas (GHG) emissions, poorer countries with fast-growing populations must do their part in climate mitigation even as they pursue economic development. Addressing intertwined issues of population growth, economic development and climate change necessitates purposeful measures and long-term commitments to a world in harmony with nature..
