As Syria has collapsed, spasming into civil war over the last five years, the effects have rippled far beyond its borders. Most notably, a surge of refugees added to already swelling ranks of people fleeing instability in Afghanistan, Iraq, Pakistan, and sub-Saharan Africa, leading to the highest number of displaced people since the Second World War. At the same time, scientists have noted record-breaking temperatures, a melting Arctic, extreme droughts, and other signs of climate change. For some, an obvious question is: what does one have to do with the other?

Environmental security? Climate security? How about planetary security. Last week at the venerable Peace Palace in The Hague, nearly 300 experts from around the world met for the somewhat dramatically named Planetary Security Conference, a new initiative aimed at bringing together people working on all things related to the environment, climate change, and their security implications.

Since the end of World War II, the number of wars between states has declined significantly, but the number of intrastate civil conflicts – as seen in Syria and Afghanistan – has increased.

There may not have been a single question about climate change in the 2016 presidential debates, but it remains a hotly contested, partisan issue for many in the United States. That climate change is happening and requires a response is not up for debate within the upper echelons of the U.S. military, however.

On October 13, the United Nations General Assembly appointed Antonio Guterres as the next UN secretary-general. When the former prime minister of Portugal and high commissioner for refugees begins his term in January 2017, he will face a world of increasing climate and security crises. In a Wilson Center NOW interview and op-ed for The Daily Climate, Wilson Fellows Ruth Greenspan Bell and Sherri Goodman express optimism in Guterres’ ability to address these interconnected challenges and provide insight on the role of institutions like the United Nations in fighting climate change.

“Climate change is one of the greatest challenges of our time and it calls for a comprehensive and cooperative international approach like we’ve never seen,” said Jainey Bavishi, associate director for climate preparedness at the White House Council on Environmental Policy, at the Wilson Center on October 5. “The leadership of the island nations is essential; they punch well above their weight on this issue.”

The United Nations has made significant progress since the Stockholm Conference of 1972 in putting the environment on the global agenda. Indeed, the environment plays a major role in two of the largest UN initiatives today: the Paris climate accord and the Sustainable Development Goals. But in a new brief for the Friedrich Ebert Stiftung Foundation, Wilson Center Fellow Ken Conca writes that the traditional approach to environmental issues is running up against its limits.
