The U.N. Intergovernmental Panel on Climate Change has just completed a series of landmark reports that chronicle an update to the current state of consensus science on climate change. In a sentence, here’s what they found: On our current path, climate change could pose an irreversible, existential risk to civilization as we know it—but we can still fix it if we decide to work together.
But in addition to the call for cooperation, the reports also shared an alarming new trend: Climate change is already destabilizing nations and leading to wars.
That finding was highlighted in this week’s premiere of Showtime’s new star-studded climate change docu-drama Years of Living Dangerously. In the series’ first episode, New York Times columnist Thomas Friedman traveled to Syria to investigate how a long-running drought has contributed to that conflict. Climate change has also been discussed as a “threat multiplier” for recent conflicts in Darfur, Tunisia, Egypt, and future conflicts, too.
Climate change worsens the divide between haves and have-nots, hitting the poor the hardest. It can also drive up food prices and spawn mega-disasters, creating refugees and taxing the resiliency of governments.
When a threat like that comes along, it’s impossible to ignore. Especially if your job is national security.
In a recent interview with the blog Responding to Climate Change, retired Army Brig. Gen. Chris King laid out the military’s thinking on climate change: “This is like getting embroiled in a war that lasts 100 years. That’s the scariest thing for us. There is no exit strategy that is available for many of the problems.”
In a similar vein, last month retired Navy Rear Adm. David Titley co-wrote an op-ed for Fox News: “The parallels between the political decisions regarding climate change we have made and the decisions that led Europe to World War One are striking – and sobering. The decisions made in 1914 reflected political policies pursued for short-term gains and benefits, coupled with institutional hubris, and a failure to imagine and understand the risks or to learn from recent history.”
In short, climate change could be the Archduke Franz Ferdinand of the 21st century.
Earlier this year, while at the American Meteorological Society annual meeting in Atlanta, I spoke with Titley, who is also a meteorologist and now serves on the faculty at Penn State University. He went from being a climate-change skeptic to labeling it “one of the pre-eminent challenges of our century.”
Excerpts of our interview:
Q: You’ve been a leader when it comes to talking about climate change as a national security issue. What’s your take on the connection between war and climate?
A: Climate change did not cause the Arab spring, but could it have been a contributing factor? I think that seems pretty reasonable. This was a food-importing region, with poor governance. And then the chain of events conspires to have really a bad outcome. You get a spike in food prices, and all of a sudden, nobody’s in control of events.
I see climate change as one of the driving forces in the 21st century. With modern technology and globalization, we are much more connected than ever before. The world’s warehouses are now container ships. Remember the Icelandic volcano with the unpronounceable name? Now, that’s not a climate change issue, but some of the people hit worst were flower growers in Kenya. In 24 hours, their entire business model disappeared. You can’t eat flowers.
Q: What’s the worst-case scenario, in your view?
A: There will be a discrete event or series of events that will change the calculus. I don’t know who, I don’t know how violent. To quote Niels Bohr: Predictions are tough, especially about the future. When it comes, that will be a black swan. The question is then, do we change?
Let me give you a few examples of how that might play out. You could imagine a scenario in which both Russia and China have prolonged droughts. China decides to exert rights on foreign contracts and gets assertive in Africa. If you start getting instability in large powers with nuclear weapons, that’s not a good day.
Here’s another one: We basically do nothing on emissions. Sea level keeps rising, three to six feet by the end of the century. Then, you get a series of super-typhoons into Shanghai and millions of people die. Does the population there lose faith in Chinese government? Does China start to fissure? I’d prefer to deal with a rising, dominant China any day.
Q: That sounds incredibly daunting. How could we head off a threat like that?
A: I like to think of climate action as a three-legged stool. There’s business saying, “This is a risk factor.” Coca-Cola needs to preserve its water rights, Boeing has their supply change management, Exxon has all but priced carbon in. They have influence in the Republican Party. There’s a growing divestment movement. The big question is, does it get into the California retirement fund, the New York retirement fund, those $100 billion funds that will move markets? Politicians also have responsibility to act if the public opinion changes. Flooding, storms, droughts are all getting people talking about climate change. I wonder if someday Atlanta will run out of water?
Think back to the Apollo program. President [John] Kennedy motivated us to land a man on the moon. How that will play out exactly this time around, I don’t know. When we talk about climate, we need to do everything we can to set the stage before the actors come on. And they may only have one chance at success. We should keep thinking: How do we maximize that chance of success?
Climate change isn’t just an environmental issue; it’s a technology, water, food, energy, population issue. None of this happens in a vacuum.
Q: Despite all the data and debates, the public still isn’t taking that great of an interest in climate change. According to Gallup, the fraction of Americans worrying about climate “a great deal” is still roughly one-third, about the same level as in 1989. Do you think that could ever change?
A: A lot of people who doubt climate change got co-opted by a libertarian agenda that tried to convince the public the science was uncertain-you know, the Merchants of Doubt. Unfortunately, there’s a lot of people in high places who understand the science but don’t like where the policy leads them: too much government control.
Where are the free-market, conservative ideas? The science is settled. Instead, we should have a legitimate policy debate between the center-right and the center-left on what to do about climate change. If you’re a conservative — half of America — why would you take yourself out of the debate? C’mon, don’t be stupid. Conservative people want to conserve things. Preserving the climate should be high on that list.
Q: What could really change in the debate on climate?
A: We need to start prioritizing people, not polar bears. We’re probably less adaptable than them, anyway. The farther you are from the Beltway, the more you can have a conversation about climate no matter how people vote. I never try to politicize the issue.
Most people out there are just trying to keep their job and provide for their family. If climate change is now a once-in-a-mortgage problem, and if food prices start to spike, people will pay attention. Factoring in sea-level rise, storms like Hurricane Katrina and Sandy could become not once-in-100-year events, but once-in-a-mortgage events. I lost my house in Waveland, Miss., during Katrina. I’ve experienced what that’s like.
Q: How quickly could the debate shift? How can we get past the stalemate on climate change and start focusing on what to do about it?
A: People working on climate change should prepare for catastrophic success. I mean, look at how quickly the gay rights conversation changed in this country. Ten years ago, it was at best a fringe thing. Nowadays, it’s much, much more accepted. Is that possible with climate change? I don’t know, but 10 years ago, if you brought up the possibility we’d have gay marriages in dozens of states in 2014, a friend might have said “Are you on drugs?” When we get focused, we can do amazing things. Unfortunately, it’s usually at the last minute, usually under duress.
