U.S. Military and Intelligence Community Witnesses Highlight Climate Risks to National Security in December Hearings
By Two U.S. Congressional hearings held in December 2019 – one in the House of Representatives and one in the Senate – either included climate change (House) or included a brief question and answer exchange between a Member and a witness on climate change (Senate) during a non-climate change focused hearing. A summary of the House Armed Services’ Subcommittee on Intelligence and Emerging Threats and Capabilities hearing is presented first. The Senate Armed Services Committee hearing exchange follows.

Higher Temperatures from Climate Change Can Deteriorate Stored Ammunition and Explosives

Climate change will affect bulk commodities, e.g., ammunition, that the U.S. Amy relies on in combat operations. As temperatures increase in arid areas of the world, such as the Middle East (which is critically important to U.S. national security), the storage of ammunition and explosives (AE) under extreme temperatures can lead to instability and possible unplanned detonations. A recent article in Scientific American explores the storage of ammunition whereby “intense heat can weaken munition’s structural integrity, cause the thermal expansion of explosive chemicals and damage protective shields.” (more…)
CCS at COP25: Time to Get Serious About Climate and Security Risks to Small Islands
CCS Senior Research Fellow LCDR Oliver-Leighton Barrett, US Navy (Ret), speaking at the “Climate and Security- emerging trends and adaptive strategies” event at COP25 in Madrid, Spain (December 11, 2019)
The European Union (EU) is taking decisive action on addressing climate change and making it an integral part of its foreign aid strategy. To advance the climate change focused portion of its foreign policy, in 2007 the EU founded the Global Climate Change Alliance (GCCA) with a charter to develop “climate security” strategies that address the strategic and political impacts of climate change. Most specifically, the GCCA aims to strengthen dialogue and cooperation, on climate change with developing countries most vulnerable to the phenomenon, in particular Least Developed Countries (LDCs) and Small Island Developing States (SIDS).
As part of this “dialogue and cooperation” effort, on the afternoon of December 11, 2019, at the U.N. Conference of the Parties 25 (COP25) in Madrid, Spain, the GCCA hosted a climate security focused side event titled “Climate and Security- emerging trends and adaptive strategies.” The event aspired to expand on understanding of the ways in which climate variability interacts with human security by examining themes that included the security implications of ecological changes on SIDS and LDCs. The Center for Climate and Security’s Senior Research Fellow, Lieutenant Commander Oliver Leighton Barrett, US Navy (retired), a former advisor to U.S. Southern Command, was invited to discuss some of these themes with the COP25 audience.

Highway Bridge Deterioration from Climate Change Will Affect U.S. Military Mobility and Deployments
By Marc Kodack
The overall state of infrastructure in the U.S. is very poor. Whether it’s energy, transit, drinking water, or inland waterways, these and other types of infrastructure are all aging and deteriorating at different rates. Climate change exacerbates the condition of many of these types of infrastructure. For the Department of Defense (DoD), infrastructure, such as bridges, roads, rail, ports, and aviation structures, is important to move personnel and equipment in response to disasters within the U.S. or for deploying overseas for humanitarian and/or combat operations. The declining state of bridges across the U.S. may impede the DoD’s ability to meet the timely execution of its assigned mission. Bridges will experience climate change effects, including those from rising temperatures that can lower physical performance leading to degradation in their life span. (more…)
