Climate change is visiting fire, floods and other harm on U.S. military bases

U.S. Navy
A Los Angeles-class submarine undergoing modifications; the U.S. Navy is concerned that its dry-dock facilities are increasingly vulnerable to storm surges intensified by climate change.

At a radar installation in Alaska, accelerating shoreline erosion has damaged a runway sufficiently to limit its use to helicopters and small aircraft, restricting access to the facility in the short term and raising a threat of long-term impairment to portions of the nation’s Arctic early-warning system.

At a military base in the Pacific, precise location undisclosed but probably Hawaii, a recent episode of rain lasting 43 straight days flooded base housing and caused mudslides that damaged base infrastructure.

And at Fort Irwin, in California’s Mojave Desert, a year’s worth of rain fell in 80 minutes one day last August, causing $64 million in damage to “more than 160 facilities — including a barracks building — 8 roads, 1 bridge, and 11,000 linear feet of fencing.”

These are but three examples of the here-and-now impacts of climate change on U.S. military bases, as gathered by the Government Accountability Office for a report on Pentagon preparedness that came out last week with little fanfare (or media attention, so far as I can detect).

The focus of the report is on what the Defense Department is doing to adapt to such problems, and the GAO’s conclusion, simply put, is: not nearly enough. Top Pentagon officials who reviewed the findings generally agreed.

While the U.S. military has been acknowledging the problem of climate change in its planning documents since at least 2010, the GAO auditors found, it has yet to prepare any concrete plans for addressing them, nor set any clear timetable for doing so.

And although most military decision-makers interviewed for the audit seemed to grasp the realities of advancing climate change, many said they felt a lack of guidance on what they should be doing about it.

Construction planners concerned with creating climate-resilient structures, for example, reported that they “lack updated guidance on construction and renovation going beyond current building codes” [emphasis added, with mild incredulity].

At the base commander level, moreover, necessary adaptation projects are rarely proposed because, even at this rather late date, “the services’ processes for approving and funding military construction projects do not include climate change adaptation in the criteria used to rank potential projects,” which puts them at a scoring disadvantage with other work.

Perhaps we can all agree that if there’s one area where over-adaptation to the risks of climate change might be justified, it’s national defense and security.

U.S. Navy
Coastal erosion in Alaska threatens a radar installation, one among many in the Arctic early-warning network that are affected by erosion or melting permafrost.

But it turns out that this, too, is a topic ripe for political manipulation by the Republicans who control the U.S. House.

GOP case against preparedness

The Pentagon authorization bill the House approved in late May includes a prohibition against spending any of the money to implement conclusions of four major documents that guide rational thinking on climate change and adaptive responses, including this year’s reports from the U.S. Global Change Research Program (which produces the National Climate Assessment) and the Intergovernmental Panel on Climate Change.

Why on earth? According to sponsoring Republican, David McKinley of West Virginia, in a memo obtained by the Huffington Post:

This amendment will prohibit the costs of the President’s climate change policies being forced on the Department of Defense by the Obama Administration. The climate is obviously changing; it has always been changing. With all the unrest around the [world], why should Congress divert funds from the mission of our military and national security to support a political ideology?

And it passed on essentially a party-line vote, with just four Democrats voting for the measure and three Republicans against.

The GAO report is an interesting blend of security-minded imprecision about exactly where among the Pentagon’s 7,500 installations certain climate impacts are showing up, coupled with photos and videos to document the damage.

Five categories of impact

It sorts the climate impacts into five broad areas where base officials had observed changes capable of causing significant impacts. Here are excerpts from its key findings in each:

Rising global temperatures:

At 8 out of 15 locations we visited or contacted, 22 officials stated that they had observed rising temperatures and associated potential impacts or mission vulnerabilities. … For example, the combination of thawing permafrost, decreasing sea ice, and rising sea level on the Alaskan coast have led to an increase in coastal erosion at several Air Force radar early warning and communication installations. According to installation officials, this erosion has damaged roads, utility infrastructure, seawalls, and runways. …

Daily operations at these types of remote radar installations are at risk due to potential loss of runways, and such installations located close to the coastline could be at risk of radar failure if erosion of the coastline continues. Air Force headquarters officials noted that if one or more of these sites is not operational, there is a risk that the Department of Defense early warning system will operate with diminished functionality.

Shifts in precipitation patterns:

At 9 out of 15 locations we visited or contacted, officials stated that they had observed changes in precipitation patterns and associated potential impacts [including the 43-day rain event mentioned above]. … By contrast, officials provided examples of impacts from reduced precipitation — such as drought and wildfire risk — and identified potential mission vulnerabilities — such as reduced live-fire training. …  

For instance, officials also told us that for the last 3 to 4 years, there has been a continuous drought at another nearby installation, which has led to an increased number of wildfires in the area. As a result of a 2012 wildfire, officials were unable to access or move ammunition at that installation for 4 days. At a third installation in the same area, officials explained that these drought conditions — and the threat of wildfire — have limited the types of ammunition that can be used on certain training ranges.

Increased storm frequency and intensity:

At 12 out of 15 locations we visited or contacted, officials stated that they had observed increasing storm frequency and intensity and associated potential impacts such as flooding, or mission vulnerabilities such as temporary or prolonged disruption of military operations. …

For example, officials at an installation located in the desert Southwest explained that flash flooding due to an intense rain event had made one of their emergency runways unusable. According to these officials, it took about 8 months for the flooding to subside. During that time, aircraft performing training and testing missions could not use the emergency runway.

Rising sea levels and associated storm surge:

At 7 out of 15 locations we visited or contacted, officials stated that they had observed rising sea levels and associated storm surge and associated potential impacts, or mission vulnerabilities. … Officials on a Navy installation told us that sea level rise and resulting storm surge are the two largest threats to their waterfront infrastructure.

For example, they explained that they were planning to lengthen a Los Angeles–class submarine to convert it to a training platform and that this will entail cutting the submarine in half. During this process, the submarine will sit in a dry dock with its interior open. Officials explained that they were concerned about possible storms and associated storm surge, noting that if salt water was allowed to flood the submarine’s systems, it could result in severe damage.

Changes in ocean characteristics:

At 3 out of 15 locations we visited or contacted, officials either stated or noted that they had observed changes in ocean temperature, circulation, salinity, and acidity at their installations and that these changes may result in impacts, or mission vulnerabilities. …

For example, an official at a Navy installation explained that changes in ocean temperature may have caused a protected turtle species to nest on a section of beach where it previously had not, making this section unavailable for potential training activities during certain parts of the year. Also, the encroachment plan of a Marine Corps installation we visited states that increases in ocean temperature could lead to degradation of coral reefs in the waters offshore of the installation.

    …..The climate is obviously changing; it has always been changing…..

    Hardly the strongest argument for doing nothing to mitigate the effects of the change–regardless of the cause.

    The asininity of that position cannot be understated.

    If the permafrost is thawing and causing damage, saying it ain’t so doesn’t stop it from happening. Heaving, buckling, and settlement will continue.

    As the drought persists in California, refusing to fund fire-fighting or refusing to create safe zones and safe passage areas is the height of stupidity.

    As Lake Mead drops to record lows, the effect of no water is not an imaginary problem to those who require water. What was the cost of supplying water in an arid Iraq?

    Crippling the mission in the name of ideology.

    McKinley

    It’s irresponsible of David McKinley to block funding for climate mitigation based on his perception of global warming. It doesn’t matter WHY climate is changing, but simply that it IS. We need to take measures to mitigate the worst of the changes and harden our infrastructure to withstand more water, bigger storms, and more prolonged fire.

    We would get ahead of the game if we also addressed global warming, but that looks like it’s a bit of a stretch given the entrenched denial from the conservative bench. Unlike what McKinley says, this is not a political issue, but rather a scientific one. If he has any issues with whether or not global warming is true, he needs to address it on the scientific level as that’s the only one the matters.

    He can rail all day long on what he does and does not believe, but it’s pretty clear that reality doesn’t give a rip what he thinks.

    My boat spent time in a Navy shipyard

    in Bremerton, Washington. In fact, that photo could have been taken there.

    Just what is the shipyard operator supposed to do to a dry dock to mitigate the “effects of climate change.”

    Put yourself in the shoes of the shipyard operator. What is he supposed to do? That’s all they’re asking and the answers from the experts aren’t forthcoming.

      Simple

      In the event of rising sea levels, the dry-dock operator should raise the perimeter and gates to prevent over-topping by the new normal and abnormal seas.

      Associated shore facilities should be reworked so that they are not subjected to flooding and inundation and remain able to service the drydock..

      And if sea levels rise many meters, entirely new facilities at the new shore line have to be built.

      It’s not genius work. Everyone knows what to do.

      Preventing even planning for what is probable is the height of foolishness.

      Now what is your guess as how long it would take to build an entirely new major naval facility?

      A year or two? Or a couple of decades?

      So should they be planning for next week, or for 50 years from now?

    Once again the thorn rises among the roses

    Actually, climate change is not harming military bases, because current weather events are not unusual. At this time in 1936, the Twin Cities was experiencing Phoenix temps with several days well over 100F. If that happened now, the warmists would be shouting about moving us all to the Yukon.
    Let’s hear Warren Buffett, CEO of some large casualty insurance companies which would be paying on all these “unusual” weather events.
    As to the frequency of extreme-weather events, we have a recent TV interview by Warren Buffett, CEO of Berkshire Hathaway, one of world’s largest casualty insurers. Buffett noted on CNBC, “While the question of climate change deserves lots of attention, it has no effect on the prices we’re charging this year versus five years ago. And I don’t think it’ll have an effect on what we’re charging three years or five years from now. Hurricanes in recent years have been all profit. Future catastrophe forecasts appear to be no different than in the past.”
    Reasonable protection of military facilities is logical; irrational panic is not. DOD is spending about $500 million on four cellulosic ethanol plants that won’t work to support biofuel production, having been sold the nonsense that regular JP8 fuel won’t be available.

      It’s not all about hurricanes…

      A battle over water at Fort Huachuca, an Army base in Arizona, illustrates the Defense Department’s growing concern over its water supply and maintaining military readiness in a water-scarce future.

      In 2007, environmental groups filed a lawsuit charging that the Army was drawing too much water from the San Pedro River, harming native endangered species. The Army and the U.S. Fish and Wildlife Service produced water conservation reports, but in 2011, a federal judge found those wanting and sent the plans back to the drawing board.

      On Jan. 31, the groups sued again, asking that a judge set a firm deadline for the Army to develop plans to reduce the amount of water it pulls from the river, which also provides the local water supply.

      Maureen Sullivan, director of environment, safety and occupational health in the Defense Department, said the increasing scarcity of water supplies is a rapidly growing issue within DoD, one that was barely a ripple a few years ago. Its importance in everything from drinking and cooking to industrial processes and equipment maintenance means the department will have to figure out new ways to operate.

      “Water is the new oil,” she said….

      …“Water is one of the most important things you can have. You have to have it to open the gates and turn on the lights,” Sullivan said.

      The Environmental Protection Agency and the National Oceanic and Atmospheric Administration have published studies showing a future of increased drought and water scarcity for the American Southwest and for portions of the southeastern states, where many DoD installations are located….

      Temperatures

      So I’m curious here. Are you making the claim that warm temperatures, such like we experienced in 1936, are not becoming more common? If so, do you have data to back up that claim? Or is your position that warm temperatures from 78 years ago ave the same cause as heat spikes today?
