Republicans Always Listen to the Pentagon—Except When It Says Climate Change Is Real

Faced with mounting scientific evidence that humans are causing climate change, Republicans are having an increasingly hard time denying the facts. Those denials became even more laughable Tuesday, when one of the party's favorite agencies, the Department of Defense, told Congress that climate change is hurting military operations.

At a Senate Foreign Relations Committee hearing, a Department of Defense representative laid out how climate change is exposing its infrastructure in coastal and Arctic regions to rising sea levels and extreme weather, and that it's even impacting decisions like which types of weapons the Pentagon buys. This is only the latest in a series of recent warnings from the military, which raised the issue as far back as George W. Bush’s second term. In March, the Pentagon warned, in its Quadrennial Defense Review, that the effects of climate change “are threat multipliers that will aggravate stressors abroad such as poverty, environmental degradation, political instability, and social tensionsconditions that can enable terrorist activity and other forms of violence.” In other words, increased drought and water shortages are likely to trigger fighting over limited resources. The military has pledged to cut its greenhouse gas footprint 34 percent by 2020and it’s already well on its way to that goal.

When the DOD says it needs something, Republicans usually listen. Perhaps the military can convince conservatives that climate change is real enough to obstruct national security?

So far, the GOP remains unconvinced. When the House of Representatives passed the Pentagon’s budget in June, it included an amendment, passed mostly along partly lines, barring the department from implementing its climate change initiatives. On Tuesday, The Hill reported that Republican Senator John Barasso called the military’s efforts to combat climate change “wasteful and irresponsible at best, especially as our friends and allies struggle with violent, deadly crises that have real implications for our security."

The Pentagon’s first task in convincing the GOP to care may be debunking the idea that the U.S. must wait for perfect science before taking action (particularly when the scientific certainty on human-caused climate change is equal to the certainty that cigarettes harm health). And as the editors at Bloomberg View recently pointed out, the military doesn’t wait for perfect certainty before assessing a threat. Waiting, generally, is a poor strategy.
