Three Climate Issues to Watch in Defense Bills this Fall

by John Conger

For many years, a bipartisan consensus has been built in Washington around the risks that climate change poses to U.S. national security priorities. Congress has passed pragmatic legislation to assess the vulnerability of military infrastructure and forces; to expand U.S. military authorities and capabilities for resilience; and to increase emphasis on the melting Arctic and new tensions between the United States and both Russia and China.  

This year, however, climate issues have been drawn into tense and partisan political debates, which at the time of this publication, look like they will lead to a government shutdown. As the overarching government funding issues take center stage, here are three climate issues to keep an eye on as Congress moves defense legislation this Fall.


CCS Welcomes 2023-2024 Class of the Climate and Security Fellowship

By Brigitte Hugh

The Center for Climate and Security (CCS) is pleased to announce the 2023-2024 class of the Climate and Security Fellowship. 

Extreme weather, food and energy crises, and global competition over clean energy are increasingly underscoring the security implications of climate change, prompting a recognition among U.S. policymakers that climate change must be at the center of U.S. national security and foreign policy. To meet this goal, there is a need for increased integration and capacity in  the U.S. security and climate workforces. The Climate Security Fellowship creates a space for mid-career professionals to explore the impact of climate on security and security on climate while building a network of professionals working at this nexus. 

The 2023-2024 class of 12 fellows comes from a diverse set of backgrounds and expertise critical to advancing a whole of society response to climate security risks. During their term, they will have opportunities to engage with expert speakers, discuss a syllabus of key climate security topics, and build relationships with the CCS network and one another. The CCS team looks forward to collaborating with them over the next nine months. 


Feeding Resilience: A Review of Policies at the Intersection of Climate Change, Food Security and National Security Policy

A CCS Report by Patricia Parera and Brigitte Hugh
Edited by Tom Ellison and Francesco Femia

Executive Summary

This report is the first of a new initiative by The Center for Climate and Security (CCS) dedicated to shining a light on the U.S. national security benefits of addressing climate change, food insecurity, and stability together. The report begins by outlining the global state of play on food security, followed by a preliminary assessment of existing U.S. initiatives that could be scaled up to increase the impact of the government’s response to climate change, food insecurity, and national security. Currently, policies and interventions often include two of the focus areas but are rarely scoped to consider all three. Thus, this landscape assessment focuses on three current nexus areas: (1) food insecurity and national security, (2) food insecurity and climate change, and (3) climate change and national security.

Following are preliminary key findings and policy recommendations considered to be a priority for policymaking action.

Climate Security at the 2023 Spring Meetings of the World Bank Group and the International Monetary Fund

By Elsa Barron and Patricia Parera

As noted by the 2022 US National Security Strategy (NSS) 2022, “The climate crisis is the existential challenge of our time.” 

In this context of enhanced urgency on the crisis, climate change– and its interconnectedness with peace, development, and humanitarian challenges– was a key subject of discussion at the 2023 Spring Meetings of the World Bank Group (WBG) and the International Monetary Fund (IMF) in Washington, DC this April. Climate change creates disproportionate and adverse effects for at-risk populations and as the negative impacts of climate change intensify, they can contribute to compounding security risks such as loss of livelihoods, competition for natural resources, migration, internal displacement, political unrest, diminished social cohesion, increased recruitment by violent extremist organizations (VEOs), malign influence by state and non-state actors, and more military deployments in response to an increased scale and tempo of natural disasters.

One of the best ways to prevent these downstream impacts is to invest in adaptation and resilience in the communities that need it most. Multilateral development banks (MDBs) such as the WBG and the IMF are one resource for delivering these climate security investments as temperatures and tensions rise. 

In its feature story on the meetings, the World Bank Group (WBG) notes that, “Positive strides were taken during the meetings in the ongoing Evolution Roadmap process, which is designed to bolster the WBG’s ability to confront the complicated development landscape and devote more resources to global challenges, like climate change, pandemics, and fragility.” The continued acknowledgment of these three interconnected, systemic global challenges by multilateral development banks will hopefully create important levers for climate security investments and action. 

The Spring Meetings served as a progress check for the Evolution Roadmap, which, in its introduction, acknowledges that “Climate change impacts, ranging from floods and droughts to locust invasions, are jeopardizing hundreds of millions of lives and livelihoods, creating hunger, conflict and forced displacement,” and later asks how these global challenges can inform the World Bank’s core mission. The following discussions from the Spring Meetings provide important context for answering that question. 

Investing in Food and Water Security

Global security hinges on water security. Dr. Nadeem Javaid, Chief Economist, Government of Pakistan, and Dr. Claudia Sadoff, CGIAR Executive Managing Director explained in the forum, “Financing for Water Action in a Changing Climate,” that water stress or water-related disasters are often the first way that communities directly experience the impacts of climate change. They argued that in addressing near-term water crises, governments and investors need to move beyond humanitarian responses alone, which are traditionally implemented after a crisis has struck. 

The presenters posited that development funds can build better prediction, preparation, and resilience systems that will make future crises less devastating. Examples given in the same session include support for policy-targeted research to improve the quality and timing of responses to water disasters such as more accurate long-range flood forecasting, flood and crop insurance for farmers, stronger soil moisture management and drainage, more drought-tolerant wheat and maize, rice that can withstand greater saltwater intrusion, and solar irrigation practices that already support millions of farmers in South Asia. Systemic global challenges highlight the need to break down the silos between climate, security, humanitarian, and development actors in planning for and implementing these solutions. 

Meeting Adaptation and Security Needs

In a session titled, “Pathways for Peace: Progress on Preventing Conflict,” the Danish Minister for Development Cooperation and Minister for Global Climate Policy, Dan Jørgensen, explained that adaptation to climate change and conflict prevention are a single issue, pointing to the significance of the US CNA Military Advisory Board identifying climate change as a challenge for security, nearly a decade before the creation of the Sustainable Development Goals (SDGs) as global targets.

In creating climate adaptation solutions that promote peace, many discussants emphasized the importance of addressing increasing migration as armed conflict, violence, climate change, and economic shocks have increased the number of displaced people. Policy planning and financial investments related to human mobility are key to determining outcomes for communities on the move. 

Some Pacific Island nations are already engaging with relocation as an adaptation measure. In a session titled, “The Imperative of Climate Change Adaptation in East Asia and the Pacific,” a representative from Fiji highlighted the inclusion of relocation as an adaptation strategy in the Climate Change Act 2021. However, relocation raises serious questions about preserving sovereignty and culture, which a representative from the Marshall Islands emphasized in a definition of security that included three components: the nation, its people, and its thousands-year-old culture. Investment in adaptation planning and consultation can equip nations to uphold this holistic definition of security.

Tackling Debt and Climate Finance

There is a direct relationship between debt and climate shocks, said Ulrich Volz, Professor of Economics and Director of the Centre for Sustainable Finance at SOAS University of London at a session on “Scaling up Climate Finance in Times of Debt Crisis.” Pakistan’s extreme flooding in 2022, illustrative of climate security risks, is a warning of crises to come. The humanitarian and economic costs of this disaster include nearly two thousand lives lost, eight million people displaced from their homes, fifteen billion dollars wiped from the economy, and decades of hard-earned socio-economic gains swept away. 

In this case and others, recovering from disaster can create overwhelming debt, making investments to prepare for future disasters untenable. In many countries today, addressing debt crises is a precondition for accelerating climate action. Targeted liquidity is required to enable the energy transition, adaptation to the impacts of extreme weather, and assurance of security in light of increasing future climate impacts. Multilateral development bank reform is one opportunity to reduce the debt burden for countries facing climate disasters and work towards greater security in outcomes. 

The current state of interconnected systemic challenges, climate adaptation needs, and debt burdens creates an imperative for including climate security analysis in decisions relating to climate finance investments and further integrating climate, security, humanitarian, and development actors. The World Bank Group and the International Monetary Fund should continue to pursue these avenues, and given rapidly-rising risks, take more significant and urgent actions in parts of the world most vulnerable to the security implications of a changing climate.
