Who is Outrider?

Outrider believes that the global challenges we face together must be solved by working together.

Among the greatest threats to the future of humankind are nuclear weapons and global climate change. Outrider makes the bold claim that both threats can be overcome — and not just by policy makers but by people with the right tools and inspiration.

Climate Change: An Escalating National Security Threat

by Outrider Staff

Rising sea levels and increasing severe weather patterns will directly impact military operations worldwide. At the same time, mounting competition for natural resources will sharpen political differences and increasingly risk outright conflict in unstable areas.

As far back as 1990, the U.S. military worried about the threat posed by global climate change. That year, the Naval War College produced a report, which flagged the impacts on naval operations. Naval bases are located, of course, on coastlines. Sea level rise and heating of the oceans and atmosphere have the potential to significantly impact the infrastructure and operations of these bases. In the decades that have followed the Naval War College report, military leaders have continued to recognize climate change as a threat.

Threat Multiplier

In 2007, several retired admirals and generals noted that climate change could contribute to repeated natural and humanitarian disasters. This would cause political instability as governments face demands that are beyond their ability to respond. Climate change acts as a “threat multiplier.” Meaning that climate change amplifies instability in volatile spots around the world. The U.S. military has cause to be concerned because it could be drawn into these hot spots.

Seven years later, in its 2014 Quadrennial Defense Review, the Defense Department affirmed the view that climate change exacerbates political instability, burdens economies, increases resource competition, and stretches government capacity to respond. This, in turn, creates conditions that are ripe for terrorist activity and other violent conflicts.

Climate change is impacting stability in areas of the world where our troops are operating today.

U.S. Defense Secretary James Mattis, March 2017

U.S. Defense Secretary James Mattis acknowledged the national security threat of climate change after his confirmation hearing in 2017. And, a 2017 House-passed defense authorization bill declared, “climate change is a direct threat to the national security of the United States.”

The Arctic

All these worries are already a reality in the Arctic. The Arctic is warming two times faster than anywhere else on the planet. The retreat of ice will open shipping lanes between the Atlantic and Pacific oceans. And, it will allow for oil and natural gas exploration in a region that contains 25% of the world's undiscovered fossil fuel reserves. This could lead to conflicts over control among nations including Russia, the U.S., and China.

The Arctic has turned into an object of territorial, resource and military-strategic interest for a number of states.

Russia has been expanding its military presence in the Arctic, building new airfields and deep-water ports. It has a fleet of icebreakers—ships designed to break through ice—larger than all the other fleets in the world combined. It also has a 40-to-2 advantage over the U.S. in icebreakers, and it plans to build at least eleven more. Russia’s military expansion could create a conflict with the U.S. as the two states will eventually vie for control of the newly accessible region. Coupled with the threat that sea level rise poses to U.S. naval bases, this could present a very real national security threat in the near future.

The damn thing melted.

U.S. Navy Secretary Richard V. Spencer, April 2018

In April 2018, Navy officials told the U.S. Senate Armed Services Committee the Navy would release a new Arctic strategy to reflect a future where transit through the Arctic will increase. This strategy needs to consider the national security threats the U.S. will face in a world where Russia may not back down from gaining influence and power in the Arctic region. The Pentagon crystalized the issue in a January report to Congress on the effects of climate change on installations and operations. The military said that of 79 military installations it examined, 53 faced a threat of recurrent flooding, while 43 faced drought, and 36 wildfires. “The effects of a changing climate are a national security issue with potential impacts to Department of Defense (DoD or the Department) missions, operational plans, and installations,” the report said. This is uncharted territory, that can hopefully be navigated peacefully.

Keeping The Peace

Addressing the causes of climate change and working toward solutions is key to preserving national and international security. If we strive for a more peaceful world, then tackling climate change has to be part of the effort.
