“In international relations today, we face two truly existential threats—in climate change and in nuclear war,” says Robert Litwak, Senior Vice President for Scholars and Director of International Security Studies, in a new episode of Wilson NOW. The interview with Litwak focuses on his new article, “Geostrategic Competition and Climate Change: Avoiding the Unmanageable,” recently published in 21^st Century Diplomacy: Foreign Policy is Climate Policy. 

“We are really taking a whole-of-government approach to address the challenges posed by climate change,” said Jennifer DeCesaro, Director for Climate Security and Resilience at the U.S. National Security Council, at a recent Wilson Center event hosted as part of the 2021 Berlin Climate and Security Conference. President Biden has taken an unequivocal position on climate change: The administration’s first order of business was to issue a series of executive orders aimed at catalyzing climate action. Putting the full institutional weight of the U.S. government behind this agenda requires a re-orientation of domestic and international security, development, and diplomacy. Creating “new muscle memory” on how we approach these typically siloed challenges is essential to elevating climate policy, said DeCesaro.

Climate change is no longer an abstract issue we may face in the future. Devastating forest fires, the hottest June on record in the United States, lethal flooding in Europe and Asia, and extreme droughts in Africa reveal that the climate is already changing with extreme consequences. Even more concerning than these events alone is the reality that the drivers of climate change, violent conflict, and fragile states compound each other. Climate change exacerbates unstable social, economic, and political conditions, while conflict and fragility can hinder effective climate change response and adaptation. The U.S. can address the compound risks created by both of these issues only through integration of conflict prevention and climate change in its foreign policy and development assistance.

Although large-scale evacuation efforts have dominated international attention, evacuation is only an option for a “tiny fraction” of the Afghan population, said Vicki Aken, Country Director for Afghanistan at the International Rescue Committee, at a congressional briefing hosted by the Tom Lantos Human Rights Commission. The briefing was focused on the evolving humanitarian situation in Afghanistan and the need for civil protection in the country. “More than 40 million Afghans will remain in Afghanistan,” said Aken. “And half of them already face critical humanitarian needs.”

As climate change impacts become starker, interest in geoengineering is growing. Geoengineering is “climate manipulation technologies that we can use to alter the climate to offset the worst parts of climate change,” says Beth Chalecki, Associate Professor of International Relations at the University of Nebraska Omaha, and Research Fellow at the Wilson Center, in a recent episode of Wilson NOW. “It sounds like a technological fix, but of course it’s not that simple,” says Chalecki.

“We need to devote our full attention to the relationship between water, climate, and security, increase understanding of the issue, and take urgent action,” said Carola van Rijnsoever, Director of Inclusive Green Growth at the Netherlands Ministry of Foreign Affairs, at a recent Hague roundtable on building a transatlantic coalition for climate action on water and security challenges in countries of risk.

Not only is the Sahel highly vulnerable to the impacts of climate change, but it is also one of the regions where climate change is most likely to undermine security and trigger violent conflict. Now more than ever, climate security risks must be effectively integrated into stabilisation and peace operations in order to achieve stability in the region.

Climate change is a defining global issue of our time. In a recent address to the UN Security Council, John Kerry, the U.S. presidential envoy for climate, remarked that climate change is “the challenge of all of our generations.” An important dimension of the challenge presented by climate change concerns its implications for state and human security.
