*Administration of Barack Obama, 2016 *

**Memorandum on Climate Change and National Security **

*September 21, 2016 *

*Memorandum for the Heads of Executive Departments and Agencies *

*Subject:* Climate Change and National Security

By the authority vested in me as President by the Constitution and the laws of the United States of America, I hereby direct the following:

*Section 1. Purpose.* This memorandum establishes a framework and directs Federal departments and agencies (agencies) to perform certain functions to ensure that climate change-related impacts are fully considered in the development of national security doctrine, policies, and plans.

*Sec. 2. Background.* Climate change poses a significant and growing threat to national security, both at home and abroad. Climate change and its associated impacts affect economic prosperity, public health and safety, and international stability. Extended drought, more frequent and severe weather events, heat waves, warming and acidifying ocean waters, catastrophic wildfires, and rising sea levels all have compounding effects on people's health and well-being. Flooding and water scarcity can negatively affect food and energy production. Energy infrastructure, essential for supporting other key sectors, is already vulnerable to extreme weather and may be further compromised. Impacts of a changing climate can create conditions that promote pest outbreaks and the spread of invasive species as well as plant, animal, and human disease, including emerging infectious disease, and these can further undermine economic growth and livelihoods. Impacts can also disrupt transportation service, cutting off vulnerable communities from relief immediately after events and reducing economic output. These conditions, in turn, can stress some countries' ability to provide the conditions necessary for human security. All of these effects can lead to population migration within and across international borders, spur crises, and amplify or accelerate conflict in countries or regions already facing instability and fragility.

Climate change and associated impacts on U.S. military and other national security-related missions and operations could adversely affect readiness, negatively affect military facilities and training, increase demands for Federal support to non-federal civil authorities, and increase response requirements to support international stability and humanitarian assistance needs.

The costs of preparing for, responding to, and recovering from the impacts of climate change are expected to increase in the coming decades. Some meteorological events (i.e., heat waves and intense precipitation) are projected to become more frequent and more severe, occur in geographic areas not previously exposed to such events, inflict more damage, heighten humanitarian needs, undermine development investments, adversely impact public health, contribute to ecological, social, and political instability, compromise diplomatic goals, and undermine national security interests. There is evidence that the rate of climate change and the resulting impacts are accelerating, even as global efforts to curb greenhouse gas pollution are increasing. The United States must take a comprehensive approach to identifying and acting on climate change-related impacts on national security interests, including by maintaining its international leadership on climate issues. *Sec. 3. Policy.* It is the policy of the Federal Government to ensure that the current impacts of climate change, and those anticipated in the coming decades, be identified and considered in the development and implementation of relevant national security doctrine, policies, and plans. This policy builds on the following Presidential directives and policies:

(a) the 2015 *National Security Strategy, *which identified climate change as an urgent and growing threat to our national security, contributing to increased natural disasters, refugee flows, and conflicts over basic resources like food and water. It added that increased sea levels and storm surges threaten coastal regions, infrastructure, and property, which in turn threatens the global economy, and compounds the growing costs of preparing and restoring infrastructure;

(b) the President's *Climate Action Plan *of June 2013, which included actions to help prepare the United States for the impacts of climate change;

(c) Executive Order 13653 of November 1, 2013 (*Preparing the United States for the Impacts of Climate Chang*e), which directed Federal agency actions to incorporate climate-resilience considerations into agency operations and other mission objectives;

(d) Executive Order 13677 of September 23, 2014 *(Climate-Resilient International Development)*, which set requirements for systematically integrating climate-resilience considerations into U.S. international development work; and

(e) Executive Order 13693 of March 19, 2015 (*Planning for Federal Sustainability in the Next Decade)*, which directed Federal actions to improve environmental performance and Federal sustainability.

*Sec. 4. Coordination on Climate Change and National Security*.

(a) *The Climate and National Security Working Group*. The Assistant to the President for National Security Affairs and the Assistant to the President for Science and Technology, or their designees, will chair an interagency working group (Working Group) to coordinate the development of a strategic approach to identify, assess, and share information on current and projected climate-related impacts on national security interests and to inform the development of national security doctrine, policies, and plans.
