The Department of Defense is organizing itself to address the effects of climate change on the U.S. military, some of which are already being felt.
“The DoD must be able to adapt current and future operations to address the impacts of climate change in order to maintain an effective and efficient U.S. military,” according to a Pentagon directive that was issued last week. See Climate Change Adaptation and Resilience, DoD Directive 4715.21, January 14, 2016.
Among other things, the new directive requires the Under Secretary of Defense for Intelligence and the Director of National Intelligence to coordinate on “risks, potential impacts, considerations, vulnerabilities, and effects [on defense intelligence programs] of altered operating environments related to climate change and environmental monitoring.”
“The Department of Defense sees climate change as a present security threat, not strictly a long-term risk,” DoD said last year in a report to Congress.
“We are already observing the impacts of climate change in shocks and stressors to vulnerable nations and communities, including in the United States, and in the Arctic, Middle East, Africa, Asia, and South America…. Although DoD and the Combatant Commands cannot prepare for every risk and situation, the Department is beginning to include the implications of a changing climate in its frameworks for managing operational and strategic risks prudently.” See National Security Implications of Climate-Related Risks and a Changing Climate, DoD report to Congress, July 2015.
“We are almost done with a baseline survey to assess the vulnerability of our military’s more than 7,000 bases, installations, and other facilities,” wrote then-Secretary of Defense Chuck Hagel in a 2014 Climate Change Adaptation Roadmap. “In places like the Hampton Roads region in Virginia, which houses the largest concentration of US military sites in the world, we see recurrent flooding today, and we are beginning work to address a projected sea-level rise of 1.5 feet over the next 20 to 50 years.”
“Politics or ideology must not get in the way of sound planning,” Secretary Hagel wrote.
“The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive,” said Republican presidential candidate Donald J. Trump in a 2012 tweet that has been retweeted more than 24,000 times. (h/t Ed Husain)
Public health insurance programs, especially Medicaid, Medicare, and the Children’s Health Insurance Program (CHIP), are more likely to cover populations at increased risk from extreme heat, including low-income individuals, people with chronic illnesses, older adults, disabled adults, and children.
“There are cities and towns across the country and around the world with immense potential; we just need to help them leverage their assets in a structured way.”
Is sole authority solvable, or is it truly the best system possible for nuclear launch authority? If the latter, should we accept that reality?
On September 3, 2025, China showcased its military power in a parade commemorating the 80th Anniversary of the end of World War II. The parade featured a large number of new military weapons and equipment, including new and modified nuclear systems that had not been previously publicly displayed. This parade was also the first time […]
