Will Global Warming Threaten National Security?

How might U.S. national security be threatened by mega-droughts, coastal flooding, killer hurricanes, food scarcity, and the other ecological calamities scientists widely predict will occur if global warming continues apace?

No one knows, but Sens. Chuck Hagel (R-Neb.) and Dick Durbin (D-Ill.) think it's time to find out. Last week, the bipartisan duo introduced a bill that would require federal intelligence agencies to collaborate on a National Intelligence Estimate to evaluate the security challenges presented by climate change.

The bill's debut is well-timed. First, it came just before the official release of a big report on the expected impacts of global warming from the Intergovernmental Panel on Climate Change. Unveiled on Friday, the report painted a sobering picture of the increased famine, drought, heat waves, fires, storms, and infectious-disease outbreaks that we can expect to riddle the globe, particularly in the world's poorest nations, if current warming trends aren't reversed. Second, it comes just as Britain has scheduled an April 17 meeting of the U.N. Security Council to discuss potential security threats posed by climate change -- the first time the body will consider the issue.

National Intelligence Estimates -- NIEs in intelligence lingo -- "are about as authoritative as it gets when it comes to written judgments concerning national security issues," explains Joe Shoemaker, Durbin's press secretary.

"They are developed to address the most serious of threats." It was an NIE on Iraq's program to build weapons of mass destruction, for instance, that the Bush administration used as key evidence (albeit deeply flawed) in making its case for invading Iraq. Other subjects of NIEs in recent years have included nuclear-weapons development in Iran and the likelihood of a Sunni-Shiite civil war breaking out in Iraq.

NIEs involve 16 intelligence agencies -- including the Central Intelligence Agency, the Federal Bureau of Investigation, and various military intelligence arms -- working together typically over three to six months, pooling data and sharing perspectives to assemble a comprehensive picture of threats to U.S. security. "It would be a significant investment of time and resources," says Shoemaker.

Durbin, assistant Senate majority leader, has long supported a federal cap on greenhouse gases, and is now broadening his case for action against climate change. "For years, too many of us have viewed global warming as simply an environmental or economic issue," he said in introducing the bill at a Senate hearing last week. "We now need to consider it as a security concern." Durbin characterized climate-change consequences as "a clear and present danger to the United States" and "a potential threat multiplier for instability around the world."

Hagel, a possible contender for the GOP presidential nomination, led the effort to block U.S. participation in the Kyoto treaty and continues to staunchly oppose mandatory restrictions on greenhouse gases, but he has been a leader among moderate Republicans in moving to address climate change in other, non-regulatory ways.
