From the Center for Climate Security:
Notably though unsurprisingly, due to consistent expressions of concern about climate change from senior defense leaders over the past year, the Department of Defense (DoD) on Sunday reaffirmed its stance on the growing national security risks associated with a changing climate. In a statement to the Washington Times, DoD spokesperson Heather Babb noted:
The effects of a changing climate continue to be a national security issue with potential impacts to missions, operational plans and installations…DOD has not changed its approach on ensuring installations and infrastructure are resilient to a wide range of challenges, including climate and other environmental considerations.
The article also quotes the Center for Climate and Security’s Director, John Conger, who commented on the practical, mission-based rationale for the military’s concern:
There are mission reasons to do these kinds of things. … If sea level rise is going to impact infrastructure, if a runway gets flooded, that’s a mission impact and that’s the kind of thing you’ve got to pay attention to.
It’s not like they’re doing some altruistic thing…They’re not trying to be good about climate change. They just recognize the reality that’s in front of you.
