Climate change and migration resources

November 20, 2023 – The Migration Policy Institute has a number of resources for organizations dealing with the intersection of migration and climate change. Worldwide, there is growing attention to the impacts of climate change on migration. While precise causality can be difficult to disentangle and estimates are all over the map, there is no doubt that the impacts of climate change are directly or indirectly increasing migration and displacement around the world. Environmental devastation can also affect people already on the move, particularly since some of the planet’s most climate-vulnerable countries are host to millions of humanitarian migrants. And some of the most affected victims of climate change are trapped populations—those prevented from moving.

The Migration Policy Institute (MPI) has developed a variety of resources to help cut through the clutter to understand the complicated dynamics and policy moves. Ahead of the COP28 summit in Dubai next week, there is no better time to explore these offerings:

  • Climate Migration 101: An Explainer is the perfect place to start. In the article, MPI Associate Policy Analyst Lawrence Huang offers answers to basic questions about the relationship between climate change and migration, starting with how and where climate change triggers human movement.
  • The explainer is one of a growing number of articles about the nexus between climate and migration published by our online journal, the Migration Information Source. Other articles, written by a range of analysts, focus on impacts in specific regions such as Central America and Southeast Asia, as well as vexing global issues regarding defining climate migration and the large numbers of individuals who remain immobile amid environmental change.
  • The podcast Changing Climate, Changing Migration features conversations with fresh thinkers and top policymakers, including former U.S. Homeland Security Secretary Michael Chertoff. The more than two dozen episodes are available on Apple PodcastsSpotify, or wherever else you get your audio content. Make sure to subscribe to catch all upcoming episodes.

The MPI website has research on climate migration and all resources on the topic collected in one place.

The Migration Policy Institute is an independent, non-partisan, non-profit think tank in Washington, D.C. dedicated to analysis of the movement of people worldwide.
