The Department of Defense (DOD) is taking significant steps in addressing climate change as a critical national security issue. By collaborating across government agencies, the DOD aims to enhance operational resilience and protect U.S. interests globally amidst growing environmental challenges.
Introduction
Climate change is reshaping the strategic landscape, posing new risks to U.S. and allied interests worldwide. The Department of Defense is leading a whole-of-government response to ensure operational resilience and maintain national security in the face of these challenges.
This article explores the DOD’s strategies and efforts in combating climate-related risks.
The Impact of Climate Change on National Security
Rising sea levels, increased natural disasters, and extreme weather conditions are creating a complex environment for military operations. According to Deputy Secretary of Defense Kathleen Hicks,
“Climate change is a national security issue… it’s fact.”
These environmental changes threaten the readiness and effectiveness of military operations, making it crucial for the DOD to address these risks head-on.
Key Climate Challenges:
- Flooding of training facilities
- Water scarcity affecting installations
- Increased frequency of urgent crises
DOD’s Climate Adaptation Strategies
To counter these challenges, the DOD has implemented a comprehensive climate adaptation plan that aligns with President Joe Biden’s framework for a whole-of-government response. This plan includes five key lines of effort:
- Climate-Informed Decisions:
- Ensuring decisions meet national defense requirements.
- Combat Forces Preparation:
- Training under extreme weather conditions.
- Resilient Infrastructure:
- Building infrastructure to sustain mission readiness.
- Supply Chain Optimization:
- Reducing vulnerability to climate effects.
- Collaboration with Allies:
- Enhancing adaptation through international partnerships.
DOD’s Key Climate Adaptation Efforts (2021-2027)
Key Effort |
Description |
|---|---|
| Climate-Informed Decisions | Meet national defense requirements with climate data. |
| Combat Forces Preparation | Train for extreme weather and terrain conditions. |
| Resilient Infrastructure | Build to sustain forces and mission readiness. |
| Supply Chain Optimization | Reduce climate vulnerability of missions and operations. |
| Collaboration with Allies | Enhance adaptation and resilience through partnerships. |
Building Resilience Across the Government
The DOD’s efforts are part of a broader government strategy. The White House recently released updated climate adaptation plans from various federal agencies, highlighting a unified approach to tackling climate change.
Brenda Mallory, chair of the White House Council on Environmental Quality, emphasized,
“The federal government is leading by example to build a more resilient future for all.”
Highlights of Federal Climate Adaptation Plans:
- Department of Commerce: Restoring coral reefs and promoting coastal resilience.
- Department of Interior: Managing wildfire risk in sagebrush ecosystems.
Future Steps and Initiatives
The DOD is set to release its updated 2024-2027 climate adaptation plan later this summer. This plan will outline further steps to ensure the department can operate effectively under changing climate conditions while preserving operational capability.
Next Steps Include:
- Using data to assess asset exposure to climate hazards.
- Mainstreaming adaptation into agency policies and planning.
Final Thoughts
The Department of Defense’s proactive approach to climate change underscores the importance of addressing environmental challenges to maintain national security.
By leading a whole-of-government response, the DOD aims to enhance resilience and readiness in the face of an increasingly unpredictable climate. This comprehensive strategy not only safeguards military operations but also sets a precedent for other federal agencies to follow.
The DOD’s commitment to climate adaptation and resilience highlights the critical intersection of environmental sustainability and national security, ensuring that the U.S. military remains prepared for future challenges.
