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 sexual and reproductive health and rights of women and girls must be protected, even – especially – during “the toughest of times, in the hardest of places,” said Kate Gilmore, deputy executive director of the United Nations Population Fund (UNFPA), at the Wilson Center on December 3. [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.

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.

The most important and anticipated climate change conference in years is finally underway. In some ways, as Bill McKibben and Andrew Revkin have pointed out, its success is relatively assured thanks to the number of major commitments countries have already made. But that doesn’t mean there’s nothing to see here. “The conference isn’t the game – it’s the scoreboard,” writes McKibben. To extend the metaphor even more, you might call it the league scoreboard, giving us a glimpse of many different storylines playing out.

In his speech on climate change and national security on November 10, Secretary of State John Kerry said climate change is already a “threat multiplier,” and that worse is to be expected if climate change continues unchecked. But the relationship between the environment and violent conflict is complex and often indirect. Researchers have been wrangling for years over the role that global environmental change plays in fueling conflict and state fragility.

The dark eyes and hair of the Pakistanis, Bangladeshis, and Afghans almost blend with the other migrants’. The brown skin tones are also not giveaways, but ask them where they come from, and you notice the hesitation – trying hard to blend into the crowd of Syrian migrants at Europe’s border crossings, afraid of being spotted and sent back.
