A
nondescript metal box at the end of an unremarkable pier in Norfolk, Va. is one
key to why the U.S. Navy is concerned about climate change.
For nine
decades, the Sewells Point tide gauge or its ancestors have been recording the
sea level off Pier 6 at Naval Station Norfolk.
The story it
tells is clear. Between naturally sinking land and global warming driven sea
level rise, the water is a half-meter higher than it was at the beginning of
the last century.
That's
creating problems at the world's largest naval base.
In rough
weather, damaging surf slams against electrical, water and steam lines under
the piers where the Navy docks its Atlantic fleet. High waves can keep sailors
from getting to the ships. Even getting on base is getting harder as
"nuisance flooding" becomes a regular problem, cutting off roads
around the city of Norfolk.
"It's
not going to stop us from accomplishing our mission. We're the military. We'll
figure it out," said Capt. Dean VanderLey, commanding officer of Naval
Facilities Engineering Command for the Mid-Atlantic region. "But it just
makes things more difficult."
"The
higher the sea level gets, the more we're going to have to deal with
that," he adds. "I don't think we fully understand the scope of the
problem. And we definitely don't fully understand the solution."
Hoax vs.
threat multiplier
The
commander-in-chief, President Donald Trump, has called global warming a hoax,
although he now says there is "some connectivity" between human
activity and climate change.
The
Pentagon, on the other hand, takes the risks of climate change seriously.
Rising seas
threaten coastal installations. Severe storms can cut off supply routes.
Extreme heat limits training.
"The
military has seen climate change as a problem since 2003, if not earlier,"
says retired Army Gen. Gerry Galloway, now with the Center for Climate and
Security.
National
security threats from climate change are included in eight defense and
intelligence documents published before President Obama took office, according
to the center.
"Climate
change acts as a threat multiplier for instability in some of the most volatile
regions of the world," a group of high-ranking former military officials
wrote in a landmark 2007 report.
"Economic
and environmental conditions in already fragile areas will further erode as
food production declines, diseases increase, clean water becomes increasingly
scarce, and large populations move in search of resources," the report
continued.
These
conditions "foster the conditions for internal conflicts, extremism and
movement toward increased authoritarianism and radical ideologies."
Planning for
the impacts accelerated under the Obama administration. In 2014, DOD published
a "Climate Change Adaptation Roadmap" outlining risks and responses.
While the
new president is a climate skeptic, his pick for secretary of defense
acknowledges the threat.
Retired
Marine Gen. James Mattis led the U.S. Joint Forces Command. The 2010 Joint
Operating Environment report that he signed described climate change as
"one of the 10 trends most likely to impact the Joint Force."
It notes the
melting of the Arctic and the competition for newly available resources
"is but one example of potential security challenges that did not exist in
the past."
Eye to the
future
Trump
supports a strong military, and "I personally don't believe that the
administration is going to do anything that's going to interfere with the
military being prepared," Galloway says.
"Now,
there will be fights over dollars," he adds, and who gets the resources
will depend on the president's defense priorities.
At Naval
Station Norfolk, they already are adapting to the realities they see coming.
Newer piers are built higher, with the utility lines under a protected concrete
deck.
"When
we do construct facilities, we're doing that with an eye toward the future, as
we always do," Capt. VanderLey says. "One of those things we see in
the future is, potentially, sea level rise."
VanderLey
stays away from the politics of climate change and how the new administration
might affect adaptation plans.
"We're
just trying to be good, smart engineers," he says. "And I can't
imagine anyone's going to decide to stop being good, smart engineers.
