Catastrophic Climate Change and National Security

World faces catastrophic climate change unless it takes action, National Security Adviser Susan Rice tells Stanford University audience 12 October 2015

Selected Remarks by National Security Adviser Susan E. Rice on Climate Change and National Security at Stanford University, October 12, 2015: [Full Text of Speech]

… In 1985—fall quarter of my senior year—scientists from around the world met to express concern that a buildup of greenhouse gasses, and specifically carbon dioxide, would result in “a rise of global mean temperature…greater than any in man’s history.” By 1990, the Intergovernmental Panel on Climate Change issued its first report, detailing how a warming climate would affect our ecosystem. There have since been four more reports, each with more sophisticated science to support ever more dire warnings.

So, it’s not that we didn’t see climate change coming. It’s that for the better part of three decades we failed, repeatedly, to treat this challenge with the seriousness and the urgency it deserves. As an international community, we succumbed to divisive global politics that set developing countries against industrialized nations and stymied international consensus on climate change.

At home, we succumbed to divisive domestic politics that allowed entrenched interests to push a calculated agenda of doubt, denial, and delay. And, we focused, quite understandably, on other critical national security priorities—from coming to grips with globalization, halting proliferation, and above all, keeping the American people safe in a post-9/11 world….

We are seizing opportunities and meeting challenges head on. And, today, we face no greater long-term challenge than climate change, an advancing menace that imperils so many of the other things we hope to achieve. That’s why, under President Obama, we have put combating climate change at the very center of our national security agenda….

In the past 15 years, we’ve had 14 of the hottest years on record—which is exactly the kind of change those climate scientists back in 1985 suggested we could be seeing by now. Last year, 2014, was the hottest. And, scientists say there’s a 97 percent chance that we’ll set a new record again this year. The seas have risen about eight inches over the past 100 years, and they’re now rising at roughly double the rate they did in the 20th century. Arctic sea ice is shrinking. Permafrost is thawing. The Antarctic ice shelf is breaking up faster than anticipated. Storms are getting stronger. Extreme precipitation events are becoming more frequent. Heat waves are growing more intense. The bottom line is this: we’re on a collision course with climate impacts that have inescapable implications for our national security. Let me sketch out a few of them.

First, climate change is a direct threat to the prosperity and safety of the American people. We’re losing billions of dollars in failed crops due to extreme drought. Millions of acres of forest have been lost to fire. In addition to longer fire seasons and drier summers here in the West, on the East Coast we’re seeing record rain events. Last week in the Carolinas, unprecedented amounts of rain fell—enough in just five days to put a serious dent in California’s multi-year drought. And, while we can’t say that climate change is the direct cause of any specific weather event, these are exactly the trends that we expect to see more of, if climate trends continue on their current trajectory.

Along our coasts, we’ve got thousands of miles of roads and railways, 100 energy facilities, communities of millions—all of which are vulnerable to sea-level rise. Remember Super Storm Sandy—how it hobbled America’s largest city and plunged everyone south of 34th Street into darkness for days? We saw a cascading failure of infrastructure. Water flooded an electrical substation, and backup power was either flooded or insufficient. Over 6,000 patients had to be evacuated from powerless hospitals down stairwells. Transportation broke down, because you can’t pump gas without electricity. Wastewater treatment plants shut down. One critical sector pulled down other vital systems. And, with warmer oceans and higher seas, New York City will have to be prepared for Sandy-level flooding to happen every 25 years.

When I visited Alaska with President Obama last month, we saw rapidly disappearing glaciers and a native community whose island home is already being washed away. The question for them is not if they will have to abandon their traditional homes and way of life, but when. These are real threats to our homeland security, and they’re happening now.

Second, climate change will impact our national defense. We’ve got military installations that are imperiled by the same rising seas as our civilian infrastructure. Here in the western United States, ranges where our troops train are jeopardized by heat and drought. In fact, this summer we had to cancel some training exercises, because it got too hot.

Climate change means operating in more severe weather conditions, increasing the wear on both service members and their equipment. There will also be new demands on our military. A thawing Arctic means 1,000 miles of Arctic coastline and new sea lanes to secure. Around the world, more intense storms—like the massive typhoon that decimated part of the Philippines two years ago—will mean more frequent humanitarian relief missions. And, our military will have to deal with increased instability and conflict around the world.

That’s a third major national security concern, because climate change is what the Department of Defense calls a “threat multiplier”—which means, even if climate change isn’t the spark that directly ignites conflict, it increases the size of the powder keg. A changing climate makes it harder for farmers to grow crops, fishermen to catch enough fish, herders to tend their livestock—it makes it harder for countries to feed their people. And humans, like every other species on this planet, scatter when their environment can no longer sustain them. As the Earth heats up, many countries will experience growing competition for reduced food and water resources. Rather than stay and starve, people will fight for their survival.

All of these consequences are exacerbated in fragile, developing states that are least equipped to handle strains on their resources. In Nigeria, prolonged drought contributed to the instability and dissatisfaction that Boko Haram exploits. The genocide in Darfur began, in part, as a drought-driven conflict. In the years prior to civil war breaking out in Syria, that country also experienced its worst drought on record. Farming families moved en masse into urban centers, increasing political unrest and further priming the country for conflict. In fact, last year, a Stanford research group determined that a rise in temperature is linked with a statistically significant increase in the frequency of conflict. There is already an unholy nexus between human insecurity, humanitarian crises, and state failure—climate change makes it that much worse.

Around the world, more than 100 million people now live less than one meter above sea level—including entire island countries in the Caribbean, the Pacific and the Indian Oceans. Consider the impacts—to the global economy and to our shared security—when rising seas begin to swallow nations whole.

Fourth, we face spreading diseases and mounting threats to global health. Already, more mosquito-borne diseases are spreading from the tropics to temperate zones as climates warm. Viruses like West Nile and Chikungunya are growing more prevalent in the United States. India is currently in the grip of the worst dengue fever outbreak in years. Livestock diseases are expanding northward into Europe. These advancing diseases cost billions of dollars a year to treat and contain, not to mention the immeasurable cost in human lives and suffering.

Finally, we cannot dismiss the worst-case predictions of catastrophic, irreparable damage to our environment. If the Greenland ice sheet melts, seas could rise not just the one to four feet many scientists predict, but eventually as much as 20 feet. If the oceans continue to acidify, it will devastate the marine coral reefs, compromising the food chain, and imperiling a major source of protein for 3 billion people worldwide.

These aren’t marginal threats. They put at risk the health and safety of people on every continent.
