In 2021, US Defense Secretary Lloyd J. Austin III referred to climate change as an “existential threat”—a term traditionally reserved for nuclear weapons. Yet two years and several strategic plans later, tangible progress to mitigate and prepare for this threat remains elusive, especially on the international scale where the greatest impacts could be realized.

When COP28 begins in the United Arab Emirates in late November of this year, the multifaceted connections between climate and conflict are expected to receive greater attention from participants than they have at previous conferences.  

While there is scant direct causal evidence to suggest that climate change causes conflict, there is a growing body of information that it can influence the risk of conflict by hurting economies, changing broad patterns of human behavior and movement, and straining social cleavages.

Peace and Prosperity in the Sahel: Climate Security is Key

Liptako-Gourma is a landlocked region located on the borders of Burkina Faso, Mali, and Niger. It possesses significant mineral, water, and biodiversity resources, and strategically positioned for both economic opportunities and cultural exchange.

Senior Western officials have received “sobering” reports on the counteroffensive  in Ukraine. As both sides continue to rain artillery shells and missiles across the country, Ukrainian forces have struggled to make progress on the front lines in both the south and the east.

Meanwhile, a different but related struggle is occurring across the country. Ukraine’s environment is being poisoned by the by-products of this war; polluting the land, water, and air, and exposing humans, plants, and animals to high levels of toxins.

Thirst for Relief: Prolonged Drought Intensifies Afghanistan’s Humanitarian Crisis

Afghanistan is the world’s sixth most affected country by climate-related threats—and its present acute challenge is water scarcity, intensified by climate change. The country is heavily reliant on agriculture, which makes up a third of its GDP.

The riparian states of the Aral Sea Basin are experiencing growing water demands, land, and environmental degradation, aging and inefficient infrastructure, and the rapid melting of glaciers. These increasing challenges are compounded by the lack of an effective transboundary water governance system.

The great power competition underway between the United States and China has a ripple effect in each nation’s neighborhood. As the United States prepares for possible conflict seven thousand miles away in the Taiwan Strait, China is expanding its economic influence in Latin America.

From individual health risks to geopolitical tensions, climate impacts are relevant to every facet of peace and security.  Focus on these links has sharpened in recent years, as governments and international security organizations like NATO increasingly recognize that climate responses must be part of promoting peace and security.
