Climate change poses risks to poor and rich communities alike, although impacts on the availability and distribution of essential resources such as water, food, energy and land will differ. These changes, combined with other social, political and economic stresses and shocks, can increase tensions within and between states, which, if unmanaged, can lead to violence. Climate-related changes to transboundary waters, food security and trade patterns, sea levels, and Arctic ice, as well as the transition to a low-carbon economy, have profound geopolitical implications.
Largescale climate-related migration may also affect the stability of states, and relations between states. Climate action itself may prove destabilizing: (mal)adaptation can disrupt economic and social relations, particularly if implemented without appropriate political economy analysis and risk assessments.
