“Water is the frontline of climate change. It’s what every report that you see identifies as the sort of first and foremost effect we see from a climate changing world,” said Sherri Goodman, a public policy fellow at the Wilson Center and formerly of CNA and the U.S. Department of Defense, on October 19.

It was some point in May last year, shortly after ISIS surged into the city of Ramadi, and I was working on a story about Iraq’s fast-disappearing Mesopotamian Marshes. Keen to fact-check a few statistics with the Ministry of Water Resources and to hear the government line on the wetlands’ struggles, I dialed its Baghdad offices. After being passed from official to official like a hot potato, a young employee, Hussein, finally gave it to me straight. “No, no, we don’t have this sort of information,” he said, clearly impatient to get off the phone. “There are much more important things in Iraq right now.”

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.

Climate change is poised to remobilize hazardous wastes that the U.S. Army abandoned and believed would be buried forever beneath the snow and ice in Greenland.

This month, Baskut Tuncak, the United Nations special rapporteur on human rights and toxics, presented the findings of his report on the effects of hazardous substances on the lives of children around the world to the 33^rd session of the Human Rights Council. His conclusions were bold and brave for their implications on conflict: States should take responsibility for cleaning up the toxic remnants of war and providing medical aid to affected communities and individuals.

Yesterday afternoon President Obama announced a new Presidential Memorandum on climate change and national security. The policy directs 20 federal agencies to consider the national security implications of climate change and establish a working group that will develop a Climate Change and National Security Action Plan for the federal government.

A bipartisan group of defense experts and former military leaders are calling on the next administration to consider climate change as a grave threat to national security.

Most citizens of democratic nations expect their governments to do their very best to make society more egalitarian, productive, adaptive, and resilient. To do so requires governments to track not just today’s headlines but grapple with long-term underlying trends, like globalization and demographic change. Governments must also make assumptions about the future course of these trends and examine how they might collide or build on one another.
