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).

Climate change impacts, such as severe drought, sea-level rise, and shifting seasonal patterns, will affect people everywhere. So it’s fitting that the new Paris Agreement places unprecedented importance on actions needed – both nationally and globally – to help people adapt, and solidifies expectations that all countries will do their part to promote greater climate resilience. It also recognizes that even the greatest resilience may not completely prevent harm to life and property, and that the global community must find ways to address “loss and damage” in cases where impacts are beyond the limits of adaptation.

The agreement coming out of the COP-21 negotiations gave breakthrough recognition to the concept of “loss and damage,” sorting through thorny discussions and politically charged negotiating positions. These positions revolved around liability and compensation, which developing countries called for but developed countries were unwilling to have included in the agreement.

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.

The nations of the world may have finally solved the thorniest problem in international relations and now we need to figure out practical solutions, said a panel of experts at the Wilson Center on December 16.

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.

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.

Climate change is a very real threat. It will have major implications for every country and region in the world, but South Asia is particularly vulnerable. To appropriately address the challenges there, the world will have to confront four misconceptions about climate change in South Asia. With world leaders convening in Paris to hash out a new agreement on climate change, now is the right time to do it.
