NBC News -- Military bases across the country have a new enemy to brace against: climate change.

That realization, Pentagon spokesman Mark Wright tells NBC News, came after a still-classified, 2008 National Intelligence Council report found that more than 30 military sites already face elevated risk -- and that’s just from rising sea levels.
“Climate change is an additional risk which we must consider and manage as part of our mission planning process,” he says.
Since World War I, the increase has been about a foot, notes Joe Bouchard, a retired Navy captain who commanded the base in the early 2000s and has since lectured and written about climate impacts on military infrastructure.
“Everything since then was built at the same level as World War I,” he says. “Nothing had been done to compensate for sea level rise because it happened slowly and people weren’t aware of it.”
By the 1990s, utility lines used to hook Navy ships up to power on shore were being impacted. “We had increasing electricity outages at high tides,” Bouchard recalls. “Electrical lines were submerged in sea water and that doesn’t work very well.”
At the time, Bouchard and others thought the base had sunk a bit since it was built on top of landfill material. That might explain part of the problem, but scientists only recently determined the entire coastal region has seen sea level increases three to four times the global average of around eight inches over the last century.
The 1990s solution was to build taller piers that would carry those utility lines higher above the sea. Four piers were eventually built but even those designs are flawed, Bouchard says, because they don’t take into account more recent projections of even higher sea level rise –- anywhere between 1.5 and 7.5 feet over the next century.
But figuring out what to do, and at what cost, is still in its infancy.
A 2011 National Research Council report found that 128
The pilot studies emphasize that each base has its unique traits, making any template more of a challenge.

Last Tuesday, local military brass, academia, city and state officials as well as industry unveiled their own pilot project to figure out what needs protecting across the region, not just on the Navy base.
“We weren’t used to coordinating with the community,” he says of the military. “But the whole region is at risk. Fixing one piece of it and not the other makes no sense.”
The group gave itself two years to come up with adaptation plans that all can support – from the 18 federal agencies in the area, to the seven city governments as well as the state and local industry.
Once the plans are in place, the next step would be to seek funding.
Community leaders have all bought in, Toll says, but “if there are any laggards it’s maybe people who don’t believe in climate change or think it’s too hard to adapt. So it is up to us to show them it’s doable.”
That convincing could reach all the way to the U.S. Congress. Last month, the House passed an amendment to ban the Pentagon from using funds to study climate change impacts.
The Senate has no similar amendment before it, so the measure might not go anywhere. But it is a symbol of how climate still is a hot potato in Congress.
The military “aren’t being encouraged by Congress to look into these things,” says retired Brig. Gen. Gerald Galloway, one of 16 retired generals and admirals who last month issued their own review, concluding that climate efforts within the military “are not being undertaken with a sufficient sense of urgency.”
“It’s a slow start because look at the pushback people have gotten when talking about climate change,” adds Galloway, a former combat engineer who now teaches disaster and water issues at the
“Typically,” he says, “the last thing people want to do is spend money if there’s any uncertainty” -- and climate projections certainly have that.
“But it’s not like we’re suggesting there’s a trillion dollar bill that’s coming due tomorrow,” he says. “We should identify risks and have a plan.”
