It is 20 years in the future. The US president and vice-president, senior generals and admirals, key cabinet members, and other top national-security officers huddle around computer screens as aides speak to key officials across the country. Some screens are focused on Hurricane Monica, continuing its catastrophic path through the Carolinas and Virginia; others are following Hurricane Nicholas, now pummeling Florida and Georgia, while Hurricane Ophelia lurks behind it in the eastern Caribbean.

On another bank of screens, officials are watching horrifying scenes from Los Angeles and San Diego, where millions of people are under mandatory evacuation orders with in essence nowhere to go because of a maelstrom of raging wildfires. Other large blazes are burning out of control in northern California and Alaska, Idaho, Oregon and Washington state. The National Guard has been called out across much of the western US, while hundreds of thousands of active-duty troops are being deployed in the disaster zones to assist in relief operations and firefighting.

With governors and lawmakers from the affected states begging for help, the president has instructed the senior military leadership to provide still more soldiers and sailors for yet more disaster relief. Unfortunately, the generals and admirals are having a hard time complying, since most of their key bases on the east and west coasts are also under assault from storms, floods, and wildfires.

Many have already been evacuated. Naval Station Norfolk, the United States’ largest naval base, for example, took a devastating hit from Monica and lies under several meters of water, rendering it inoperable. Camp Pendleton in California, a major Marine Corps facility, is once again in flames, its personnel either being evacuated or fully engaged in firefighting. Other key bases have been similarly disabled, their personnel scattered to relocation sites in the interior of the country.

Foreign threats, while not ignored in this time of domestic crisis, have lost the overriding concern they enjoyed throughout the 2020s when China and Russia were still considered major foes. By the mid-2030s, however, both of those countries were similarly preoccupied with multiple climate-related perils of their own – recurring wildfires and crop failures in Russia, severe water scarcity, staggering heat waves, and perpetually flooded coastal cities in China – and so were far less inclined to spend vast sums on sophisticated weapons systems or to engage in provocative adventures abroad. Like the United States, these countries are committing their military forces ever more frequently to disaster relief at home.

As for America’s allies in Europe: Well, the days of trans-Atlantic cooperation have long since disappeared as extreme climate effects have become the main concern of most European states. To the extent that they still possess military forces, these too are now almost entirely devoted to flood relief, firefighting, and keeping out the masses of climate refugees fleeing perpetual heat and famine in Asia and Africa.

And so, in the Situation Room, the overriding question for US security officials in 2039 boils down to this: How can we best defend the nation against the mounting threat of climate catastrophe?

Back to the present

Read through the formal Pentagon literature on the threats to American security today and you won’t even see the words “climate change” mentioned. This is largely because of the nation’s commander-in-chief, who once claimed that global warming was a “hoax” and that we Americans are better off burning ever more coal and oil than protecting the nation against severe storm events or an onslaught of wildfires.

Climate change has also become a hotly partisan issue in Washington, and military officers are instinctively disinclined to become embroiled in partisan political fights. In addition, senior officers have come to view Russia and China as vital threats to US security – far more dangerous than, say, the zealots of ISIS or al-Qaeda – and so are focused on beefing up America’s already overpowering defense capabilities yet more.

“Inter-state strategic competition, not terrorism, is now the primary concern in US national security,” the Department of Defense (DoD) affirmed in its National Defense Strategy of February 2018. “Without sustained and predictable investment to restore readiness and modernize our military to make it fit for our time, we will rapidly lose our military advantage.”

Everything in the 2018 National Defense Strategy and the DoD budget documents that have been submitted to Congress since its release proceed from this premise. To compete with China and Russia, we are told, it’s essential to spend yet more trillions of dollars over the coming decade to replace America’s supposedly aging weapons inventory – including its nuclear arsenal – with a whole new suite of ships, planes, tanks and missiles (many incorporating advanced technologies like artificial intelligence and hypersonic warheads).

For some senior officers, especially those responsible for training and equipping America’s armed forces for combat on future battlefields, weapons modernization is now the military’s overriding priority. But for a surprising number of their compatriots, other considerations have begun to intrude into long-term strategic calculations. For those whose job it is to house all those forces and sustain them in combat, climate change has become an inescapable and growing concern. This is especially true for the commanders of facilities that would play a critical role in any future confrontation with China or Russia.

Many of the bases that would prove essential in a war with China, for example, are located on islands or in coastal areas highly exposed to sea-level rise and increasingly powerful typhoons. Equally vulnerable are stateside bases considered essential to the defense of the US, as well as its ability to sustain military operations abroad.

Wildfires in California have also imperiled key bases. In May 2014, for example, Camp Pendleton was scorched by the Tomahawk Fire, one of several conflagrations to strike the San Diego area at the time. More than 2,400 hectares was burned by the blaze and children at two on-base schools had to be evacuated. At one point, a major munitions depot was threatened by flames, but firefighters managed to keep them far enough away to prevent a catastrophic explosion.

An even more dangerous fire swept through Vandenberg Air Force Base, 80 kilometers north of Santa Barbara, California, in September 2016. Vandenberg is used to launch satellite-bearing missiles into space and houses some of the Ground-Based Midcourse Defense missile interceptors that are meant to shoot down any North Korean (or possibly Chinese) ICBMs fired at the US. The 2016 blaze, called the Canyon Fire, burned more than 4,800 hectares and forced the USAF to cancel the launch of an Atlas V rocket carrying an earth-imaging satellite. Had winds not shifted at the last moment, the fire might have engulfed several of Vandenberg’s major launch sites.

Such perils have not (yet) been addressed in Pentagon documents like the National Defense Strategy and senior officers are normally reluctant to discuss them with members of the public. Nonetheless, it’s not hard to find evidence of deep anxiety among those who face the already evident ravages of climate change on a regular basis. In 2014 and 2017, analysts from the US Government Accountability Office visited numerous US bases at home and abroad to assess their exposure to extreme climate effects and came back with startling reports about their encounters.

“At seven out of 15 locations we visited or contacted,” the survey team reported in 2014, “officials stated that they had observed rising sea levels and associated storm surge and associated potential impacts, or mission vulnerabilities.” Likewise, “at nine out of 15 locations we visited or contacted, officials stated that they had observed changes in precipitation patterns and associated potential impacts,” such as severe flooding or wildfires.

Look through the congressional testimony of top Pentagon officials and you’ll find that similar indications of unease abound. “The air force recognizes that our installations and infrastructure are vulnerable to a wide variety of threats, including those from weather, climate, and natural events,” said John Henderson, assistant secretary of the air force for installations, environment and energy, at a recent hearing on installation resiliency. “Changing climate and severe weather effects have the potential to catastrophically damage or degrade the air force’s war-fighting readiness.”

Threats to the home front

At a time when US bases are experiencing the ever more severe effects of climate change, the armed forces are coming under mounting pressure to assist domestic authorities in coping with increasingly damaging storms, floods and fires from those same climate forces. A prelude to what can be expected in the future was provided by the events of August and September 2017, when the military was called upon to provide disaster relief in the wake of three particularly powerful hurricanes – Harvey, Irma and Maria – at the very moment California and the state of Washington were being ravaged by powerful wildfires.

This unprecedented chain of disasters began on August 26, when Harvey – then a Category 4 hurricane – made landfall near Houston, Texas, and lingered there for five agonizing days, sucking up water from the Gulf of Mexico and dumping it on that area in what proved to be the heaviest continuous rainfall in American history. With much of Houston engulfed in floodwaters, the DoD mobilized 12,000 National Guard and 16,000 active-duty army troops to assist in relief operations.

Such cleanup operations were still under way there when Irma – a Category 5 storm and one of the most powerful hurricanes ever detected in the Atlantic Ocean – struck the eastern Caribbean, Puerto Rico and southern Florida. Guard units sent by Florida’s governor to assist in Texas were hastily recalled and the Pentagon mobilized an additional 4,500 active-duty troops for emergency operations. To bolster these forces, the navy deployed one of its aircraft carriers, the USS Abraham Lincoln, along with a slew of support vessels.

With some Guard contingents still involved in Texas and cleanup operations just getting under way in Florida, another Category 5 storm, Maria, emerged in the Atlantic and began its fateful course toward Puerto Rico, making landfall on that island on September 20. It severed most of that island’s electrical power lines, bringing normal life to a halt. With food and potable water in short supply, the DoD commenced yet another mobilization of more than 12,000 active-duty and Guard units. Some of them would still be there a year later, seeking to restore power and repair roads in remote, harshly affected areas.

If finding enough troops and supply systems to assist in these relief operations was a tough task – akin to mobilizing for a major war – the Pentagon faced a no less severe challenge in addressing the threats to its own forces and facilities from those very storms.

When Hurricane Irma approached Florida and the Keys, it became evident that many of the Pentagon’s crucial southern installations were likely to suffer severe damage. Notable among them was Naval Air Station (NAS) Key West, a major hub for US operations in the Caribbean region. Fearing the worst, its commander ordered a mandatory evacuation for all but a handful of critical personnel.

Commanders at other bases in the storm’s path also ordered evacuations, including at NAS Jacksonville in Florida and Naval Submarine Base Kings Bay in Georgia. Aircraft at these installations were flown to secure locations further inland, while Kings Bay’s missile-carrying submarines were sent to sea, where they could better ride out the storm. At least a dozen other installations were forced to relocate at least some personnel, planes and ships.

Clusters of extreme events

While the extremity of each of these individual climate disasters can’t be attributed with absolute certainty to climate change, that they occurred at such strength over such a short time period is almost impossible to explain without reference to it. As scientists have indicated, the extremely warm waters of the Atlantic and Caribbean contributed to the fury of the three hurricanes and extreme dryness in California and the American west has resulted in severe recurring wildfires. All of these are predictable consequences of a warming planet.

That means, of course, that we can expect recurring replays of summer 2017, with multiple disasters (of ever-increasing magnitude) occurring more or less simultaneously. These, in turn, will produce ever more demands on the military for relief services, even as it is being forced to cope with the impact of such severe climate events on its own facilities. Indeed, the National Research Council (NRC), in a report commissioned by the US Intelligence Community, has warned of just such a future. Speaking of what it termed “clusters of extreme events,” it noted that warming temperatures are likely to generate not just more destructive storms, but also a greater concentration of such events at the same time.

“Given the available scientific knowledge of the climate system,” the report notes, “it is prudent for security analysts to expect climate surprises in the coming decade, including … conjunctions of events occurring simultaneously or in sequence, and for them to become progressively more serious and frequent thereafter, and most likely at an accelerating rate.”

Combine the ravages of Harvey, Irma, Maria, Katrina and Sandy with the wildfires recently blasting across California and you get some sense of what our true “national security” landscape might look like. While the Pentagon, the National Guard and local authorities should be able to cope with any combination of two or three such events, as they did in 2017 (although, according to critics, the damage to Puerto Rico has never been fully repaired), there will come a time when the climate assault is so severe and multifaceted that US leaders will be unable to address all the major disasters simultaneously and will have to pick and choose where to deploy their precious assets.

At that moment, the notion of focusing all our attention on managing military rivalries with China and Russia (or other potential adversaries) will appear dangerously distracting. Count on this: US forces sent to foreign bases and conflicts (as with the never-ending wars of this century in the Greater Middle East and Africa) will undoubtedly be redeployed homeward to help overcome domestic dangers. This may seem improbable today, with China and Russia building up their arsenals to counter American forces, but scientific analyses like those conducted by the United Nations’ Intergovernmental Panel on Climate Change (IPCC) and the NRC, suggest that those two countries are then no less likely to be facing multiple catastrophes of their own and will be in no position to engage in conflicts with the United States.

And so there will come a time when a presidential visit to the Situation Room involves not a nuclear crisis or the next major terrorist attack, but rather a conjunction of severe climate events, threatening the very heartbeat of the United States.
