The effects of climate change are already evident at Defense Department installations in the United States and overseas, and DOD expects climate change to challenge its ability to fulfill its mission in the future, according to the first DOD Climate Change Adaptation Roadmap.
John Conger, the acting deputy undersecretary of defense for installations and environment told American Forces Press Service the roadmap was completed in 2012 and published early this year.
The document had us do a variety of things, Conger said. But the piece that I think is the crux of the report is, rather than creating a stovepipe within the DOD organizational structure to deal with climate change, [the document says] we are going to integrate climate change considerations into the normal processes, the day-to-day jobs of everybody.
Such language is going to be integrated into various guidance documents, he added, and weve already started doing that.
The departments action is part of a federal government effort to address the global challenge. In June, President Barack Obama launched a Climate Action Plan to cut carbon pollution, prepare communities for climate change impacts and lead similar international efforts.
Across the United States, local communities and cities are updating building codes, adjusting the way they manage natural resources, investing in more resilient infrastructure and planning for rapid recovery from damage that could occur due to climate change.
And on Nov. 1, the president issued an executive order on climate preparedness directing federal agencies to modernize programs to support climate-resilient investments, manage lands and waters for climate change preparedness and resilience, and plan for climate-change-related risk, among other things.
The order also forms an interagency council on climate preparedness and resilience, chaired by the White House and composed of more than 25 agencies, including the Defense Department.
The foundation for DODs strategic policy on climate change began with the defense secretarys publication in 2010 of the Quadrennial Defense Review. The QDR, produced every four years, translates the National Defense Strategy into policies and initiatives.
In 2010, the QDR for the first time linked climate change and national security. It said climate change may affect DOD by shaping the departments operating environments, roles and missions, have significant geopolitical impacts worldwide, and accelerate instability or conflict.
The QDR said DOD also would have to adjust to climate change impacts on its facilities, infrastructure, training and testing activities and military capabilities.
As the acting deputy undersecretary of defense for installations and environment, Conger also is the departments senior climate official, and his first job is to manage the installations and environment portfolio.
That includes over 500 bases and 300,000 buildings and 2.2 billion square feet of space, he said. The infrastructure has a plant replacement value on the order of $850 billion. Theres a lot of stuff out there that is all going to be impacted by changes in the climate.
Conger said the department has to plan for the contingencies that climate change poses just as it would plan for any other contingency, driven by any other force in the world.
As I look at managing the infrastructure, I have to think about risk as well in that context, he said. What is climate change likely to do? What are the major changes that will occur that will affect that $850 billion real property portfolio?
The obvious threats are things like a rise in sea-levels, storm surges and storm intensity, but theres also drought and thawing permafrost that affects bases in Alaska, the deputy undersecretary added.
Similarly, on our installations we have over 400 endangered species, he said. We manage those species through documents called integrated natural resources management plans and we manage [them] not through some degree of altruism Ö but the fact is that if we dont manage those species effectively and they do appear more threatened, then other regulatory agencies will put limits on what we can do on our property and that will impact training.
Conger added, We said, ëTake climate into account. Make sure you have planned for this. Make sure you have thought about it and addressed it in your [installation management] plans.
These are all, in my mind, sensible, reasonable steps that dont cost very much money today and just require a little bit of forethought in order to reduce our exposure to risk tomorrow.
The presidents June Climate Action Plan categorized recommendations for action in terms of mitigating or eliminating emissions that cause climate change, adapting to climate change, and working internationally on climate change, Conger said.
DOD has been looking at mitigation, or the energy problem, for a long time, the deputy undersecretary added.
Energy and climate are tied together, Conger said, because energy and emissions are tied together.
We are working very hard and diligently to reduce our energy usage, to reduce our energy intensity and to increase the use of renewable energy, which doesnt have emissions, he said. And we have done each of these things not because it is good for the climate or because it reduces emissions but because they provide mission and monetary benefits.
Conger says the departments $4 billion annual utility bill drives the search for energy-efficiency, renewable-energy development projects and more. All have benefits from a mission perspective first, he said, and also turn out to be good for the environment.
