The Online Home for CCS Has Moved!
As of August 2025, the CCS website will serve as an archived resource. Please visit us at councilonstrategicrisks.org/ccs/ for resources, upcoming publications, and more.
The CCS blog will remain active. Those subscribed to the mailing list will continue to receive notifications for the latest blog posts until we offer that capability from the CSR site.

Feeding Resilience: Ethiopia
Ethiopia sits at the intersection of climate change, food security, and conflict risks that will shape the country’s internal stability, influence on East African security, and geopolitical role for years to come.
Today, the country is in danger of falling into a new round of war or instability, which would exacerbate humanitarian suffering, deepen hunger, destabilize the region, and ripple throughout global trade and geopolitical competition. These challenges will only grow more difficult to address as climate change impacts on agriculture intensify. But Ethiopia’s record of progress speaks to its possibilities as a peaceful, stabilizing, and agriculturally thriving state. Integrated near- and long-term investments by regional and international powers in conflict mediation, food security, and climate resilience can help deliver this future, for the benefit of Ethiopia and global security.
Today, the Center for Climate and Security (CCS), in partnership with Woodwell Climate Research Center, published a new case study exploring intersecting security, food, and climate issues in Ethiopia as part of its Feeding Resilience program.
The Center for Climate and Security at Climate Week NYC
Members of the Center for Climate & Security (CCS) team are in New York this week for Climate Week NYC, one of the largest gatherings of leaders, policymakers, and civil society convening to drive climate action. The team is hosting public events on topics ranging from geoengineering, nationalism and climate backsliding, and the climate security landscape in the Asia-Pacific.
Learn more and register for events below.
Climate Intervention at High Latitudes: A Security Simulation
Tue, Sep 23, 10:30 AM – 12:30 PM
In this 2030 scenario exercise, co-hosted by CCS and Reflective, participants will explore the geopolitical implications of a potential stratospheric aerosol injection (SAI) deployment.
The National Security Salon
Tue, Sep 23, 11:30 AM – 7:00 PM
CCS Advisory Board member Sherri Goodman will give closing keynote remarks at the National Security Salon. The event explores the nexus of climate change, national security, and emerging geopolitical opportunities, and their impact on the climate investment landscape.
Climate Ambition in the Asia-Pacific: Progressive NDC 3.0 for Stronger National Resilience
Tue, Sep 23, 1:00 PM – 3:00 PM
CCS Director Erin Sikorsky will moderate a panel with speakers from Taiwan Climate Action Network, The Australia Institute, and Solutions for Our Climate (South Korea) on climate policy and security in the Asia-Pacific.
4th Annual Climate & Conflict Convening
Fri, Sep 26, 9:00 AM – 2:30 PM
CCS Deputy Director Tom Ellison will give opening remarks at the Peace Department’s fourth annual Climate and Conflict Convening in Greenwich, CT. The event explores the implications of rising nationalism and climate policy reversals in the United States and ways forward. Shuttle transport from NYC is available.
A Dose of Realism: Geopolitical and Security Dimensions of Solar Radiation Modification
Earlier this year, a spate of news stories in the United Kingdom featured the so-called “weaponization” of solar geoengineering, conjuring up a future in which Vladimir Putin attacks the country with a targeted stratospheric injection aimed at causing an environmental disaster. Not only is such a scenario currently unlikely from a scientific and technical point of view, it also distracts from a conversation about managing the more realistic security dynamics related to Solar Radiation Modification (SRM), techniques designed to cool the planet artificially by reflecting sunlight back into space. Research, development, and potential future deployment of climate interventions like SRM face a range of security challenges, including conspiracy theories and disinformation, intersections with existing tensions over transboundary resources, and the potential to deepen fissures in the already fractured geopolitical environment.
Recognizing these security risks does not amount to rejecting SRM, just as noting the risks of the energy transition does not justify clinging to fossil fuels. Instead, these security dynamics must be better understood, prepared for, and managed by both security actors and those funding and conducting SRM research.
(more…)The State of Human Mobility at the Nexus of Climate, Food, and Conflict
By Siena Cicarelli and Erin Sikorsky
Deep funding cuts and political shifts in the United States, along with other multilateral actors turning inward, have weakened investment in climate security and migration governance. At the same time, accelerating climate impacts are undermining crop yields, shifting growing seasons, and destabilizing food supply chains, especially in sub-Saharan Africa and South Asia. These pressures are fueling hunger, malnutrition, and displacement, with 64.3 million people internally displaced in food crisis contexts in 2023 and 123.2 million people forcibly displaced worldwide in 2024.
