This fall, the National Intelligence Council released an intelligence community assessment of the extent to which factors such as climate change, severe weather, conflict, resource scarcity, disease, poor governance, and environmental degradation will impact peoples’ purchasing power and food availability over the next decade. They found “the overall risk of food insecurity in many countries of strategic importance to the United States will increase.”

An article in the Annual Review of Sociology reviews much of the research on the relationship between environmental factors and migration, providing a timely overview of a complex field. “Migration is often a household strategy to diversify risk,” write Lori Hunter et al., but can be influenced by any number of determinants, including at the macro level (e.g., environmental, social, cultural, economic, and political dynamics), the meso level (e.g., intervening obstacles and facilitators), as well as the micro level (e.g., personal and household characteristics).

One of the hidden costs of climate change is the displacement of millions of people in some of the poorest regions of the globe. The existing international refugee regime is ill-suited to cope with those seeking refuge from environmental disasters. Countries must get serious about developing coordinated plans to address the issue, lest they be caught by surprise when another humanitarian crisis hits.

Aissata M.B. Camara grew up in an educated, upper income household in Guinea, West Africa. One morning, she woke up to singing outside her window and knew they were coming. Many in her community thought that she was unclean and would grow up to be promiscuous if she wasn’t cut. She would be unmarriageable. While her family and community members held her down, she realized, “my body no longer belonged to me.” [Video Below]

Migrants and Syrian refugees have become the new “stranded polar bear” of climate change imagery. But most such impacts will seldom be so dramatic or camera-ready.

Security was inseparable from the climate talks in Paris, from the safety of conference participants to how climate change impacts the stability of nations.

The new climate deal coming out of Paris commits governments to hold the rise in average global temperatures to “well below” two degrees Celsius compared to preindustrial levels. An important dimension of this agreement calls for subsequent work on limiting the increase to 1.5 degrees. This is an important win for islands and other low-lying countries, and for humanity.

Global attention is understandably focused on Syrian refugees, but the migration crisis in Europe is part of a bigger trend that climate and social scientists have been warning about for years.
