A project that anticipates how people will move in response to environmental changes could help to bolster social and humanitarian support for countries in crisis.

A new model estimates how many climate migrants there will be, where they are likely to go, and what effects they might have on the places to which they move.

A new report is the first to focus on longer-term climate impacts on crop and water resources, and the ways in which they may influence internal migration.

If emissions of greenhouse gases remain high, as many as 143 million “internal migrants” might move within their own countries by 2050.

At a recent event, Earth Institute experts discussed the social, political, and economic challenges of climate migration.
