Whether or not we respond to climate change – and the security implications of that decision – is a major public policy question. But increasingly experts are paying closer attention to how we respond.

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.

In a commanding speech at Old Dominion University this week, Secretary Kerry announced a dramatic step toward integrating climate and security into U.S. foreign policy. In Norfolk, Virginia, home to the world’s largest naval station, Kerry said the State Department is creating a new “task force of senior government officials to determine how best to integrate climate and security analysis into overall foreign policy planning and priorities.”

When the leaders of the G7 countries – Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States – met earlier this month, they agreed to make fossil fuels a thing of the past by 2100.

Rapid population growth can be a contributing factor to climate change vulnerability and should be considered in climate adaptation and peacebuilding efforts, said the Wilson Center’s Roger-Mark De Souza at a workshop on climate change adaptation and peacebuilding hosted by the Institute for Security Studies (ISS) in Addis Ababa.
