The Pentagon often wargames future scenarios for when ‘all hell breaks loose’ with the idea of training for the worst-case scenario. Secretary of Defense Lloyd Austin made clear when he took the helm at the Pentagon earlier this year, that – consistent with President Joe Biden’s focus on climate change – the DOD would include climate as a threat to national security in the next iteration of the National Security Strategy. He also said that the impacts of climate change will be included in wargaming future military exercises. As part of The Cipher Brief’s Climate Series, Co-Editor Kristin Wood talked with the author of All Hell Breaking Loose: The Pentagon’s Perspective on Climate Change, to get a sense of where the US military may be headed when it comes to dealing with the current and future impacts of climate change.
