Climate change is threatening military operations and soldiers in Arizona, across the nation and worldwide, warns a retired brigadier general who now heads a research and public policy organization that examines long term threats to national security.  

Estimates put Arizona as the fourth鈥揻astest warming state and Phoenix as the second-fastest warming city in the nation, and that鈥檚 placing the military at risk here, said retired U.S. Marine Brigadier General Stephen Cheney, president and CEO of the nonprofit American Security Project (ASP) in Washington, D.C.  

鈥淓xtreme heat, drought and wildfires affect the day-to-day lives of Arizonans and Arizona businesses, and climate change really impacts military training and readiness,鈥� said Cheney, who recently spoke to a group of Arizona government and community leaders at an event entitled National Security in the Time of Climate Change. 

The event was hosted by the nonprofit Arizona Forward, which advocates for a balance between economic development and environmental quality in the state.

鈥淣ational security is typically not a top of mind issue when we consider climate change,鈥� said  Lori Singleton, president and CEO of Arizona Forward that partnered with ASP, the Environmental Defense Fund and the Association of Defense Communities to 鈥渟potlight this critical topic.鈥� 

Heat, drought impact Arizona鈥檚 seven military bases

In Arizona, this summer鈥檚 record-breaking heat wave is undoubtedly impacting the state鈥檚 military bases, Cheny said. While the state hasn鈥檛 seen the devastation that bases in the country鈥檚 Hurricane Alley have suffered, the extreme heat impacts outdoor training and even the ability to deploy quickly, Cheney said. 

鈥淲hen temperatures reach 90 or above in the military, we call it a black flag day and literally raise a flag where all outdoor physical training stops,鈥� said Cheney, a 30-year veteran of the Marine Corps and former member of the Secretary of State鈥檚 International Security Advisory Board and the Department of State鈥檚 Foreign Affairs Policy Board.

Extreme heat also can prevent a military plane from taking off to deploy troops to an assignment, he said. 

Heat exhaustion, dehydration among soldiers rising  

Active duty members suffering from heat stroke and exhaustion also are on the rise, said Cheney, citing a joint report issued by NBCNews and InsideClimateNews last year.

More U.S. troops are falling to heatstroke as the military struggles to balance training with rising temperatures, according to the . Statistics show that in 2008, there were 1,766 cases of heat stroke or heat exhaustion among active duty members. By 2018, that number had grown to 2,792, a 60 percent increase, he said.

鈥淚t鈥檚 really posed a huge risk, certainly the health impacts, and some estimates are that it cost the military $1 billion just for that decade,鈥� Cheney said.

Damage to military installations costing taxpayers

The U.S. Department of Defense maintains installations worldwide worth over $1.2 trillion that are critical to U.S. national security. In the past several years, military bases have seen extensive damage from climate change, Cheney said.

For example, Hurricane Florence in 2018 caused an estimated $3.6 billion in combined damages to three bases in North Carolina: Camp Lejeune, Marine Corps Air Station New River, and Marine Corps Air Station in Cherry Point. 

Military funds had to be reallocated to handle hurricane repair along with curtailing training and deployments, Cheney said.  

Not the radical left wing

Cheney, who has seen firsthand the damage caused by increasingly erratic weather at military bases, said he and other retired military officials and others are trying to create awareness around the topic that often is described as a 鈥渓eft wing鈥� issue, he said. 

鈥淚t鈥檚 not a Republican or Democrat issue. It鈥檚 a national security issue and it鈥檚 not going away,鈥� Cheney said. 

Worldwide conflicts and instability also can be tied to climate change, he said. One example is the long drought in Syria that dried up agricultural yield, driving people from rural areas into cities that helped fuel conflicts with ISIS. 

Military and national security initiative for carbon-free air

The ASP, its board and more than 80 military and national security leaders that have joined its  Consensus for American Security want to raise public awareness about concerns that affect national security like climate and energy security, terrorism, economic competitiveness, trade, public diplomacy, and more.

Through research, they are making public policy recommendations to forge bipartisan consensus on national security strategy.

Among the policies they are recommending to address changing weather are investment in  clean and renewable energy, more weather resistant military installations and global partnerships to fight climate change. 

鈥淲e really can鈥檛 afford to ignore the risks,鈥� Cheney said. 鈥淚f there鈥檚 one thing that鈥檚 threatened most, it’s our national military and we鈥檙e seeing it worldwide.鈥�
