The US Congress is currently considering multiple bills on climate change and energy security. In December, the world will meet in Copenhagen to consider a framework for a post-Kyoto agreement. Perhaps it is time we had a serious discussion about what these issues mean for US national security.
Environmentalists often point to climate change as the source for all manner of ills, including the destruction of Pacific Islands and low-lying coastal areas, massive immigration issues in South Asia, and perhaps even war. There may be a grain of truth to these claims, but they seem distant from the average American voter. Let's focus instead on three issues that are clear and present dangers from America's current energy and climate policies.
First, there is the full cost of America's oil dependence. As the global economy shows signs of recovery, the price of oil has quietly crept above $70 a barrel, a price far above the historic trend. Indeed, the recent collapse in investment in the oil sector means that oil prices could continue to rise. Follow the money: America is sending more than $500 billion a year overseas to oil-exporting countries. Most of those countries have autocratic political systems that are unprepared to handle that kind of financial influx. Oil money often turns into military spending and advanced weaponry, which in turn leads to civil and international war. Ironically, this costs America even more money in the long-run, as it spends billions on the military to try to maintain "stability" in oil-exporting regions.
Second, there is the full cost of doing nothing about climate change. The US Navy has hundreds of concrete piers around the world that are likely to be submerged by rising seawater, and the cost to replace them is estimated at $100 billion. Insurance companies will raise premiums for natural disasters. The government will spend millions developing early-warning systems and mitigation systems in light of more frequent hurricanes like Katrina and Gustav. These are just a few examples of the costs climate change will impose on the public. Whenever some pundit complains about the cost of environmental policies, remember the implicit price tag of doing nothing.
Third, there is the real but unquantifiable risk of catastrophic climate change. The single biggest risk is that the ocean currents will change, diverting the warm Gulf current from the North Atlantic and bringing a rapid ice age to Europe. If this sounds like the stuff of Hollywood, well, it is, but it is also a significant risk that has been highlighted by the UN International Panel on Climate Change. This risk is real, and it is a threat to the US military in two ways. First, chaos in Europe would threaten many of America's most important allies, not to mention the thousands of US troops posted in Germany and elsewhere. Second, this sort of disruption in Europe would destabilize the US-Russia relationship in ways that are impossible to predict.
You don't have to be a tree-hugger or a radical hawk to see energy and climate change as serious issues of US national security. It's time to see these issues as a statesman would: from a bipartisan, long-term perspective. Obama's move to increase the gas-mileage was a good first step, but more is needed. It will take decades to convert the capital stock of US power plants into cleaner, more efficient technology, even if the right policy incentives were put in place today. To make that happen, the US needs to see the issue not just as an environmental problem, but also a security imperative.
But have hope. Far-sighted politicians are starting to watch for the first moment when the words "carbon tax" become politically palatable. It will pay to be out front on this issue.
