TIL about national security

Hi everyone. So before we get started, I wanted to let you know that this is going to be maybe a heavier episode. So if you're not in the headspace for it, maybe come back to it another time. Hello and welcome to Today I Learned Climate. I'm Lar Hesse Fisher from the MIT Environmental Solutions Initiative. Today we're building on a conversation that started in our last episode with Professor James Renwick about sea level rise.

You might remember that toward the end of our conversation, Professor Renwick said this. For a country, say like Vietnam or Bangladesh, and even parts of China, we're talking millions of people, maybe tens of millions of people being displaced by sea level rise. the kind of political tensions and national security issues that might come with some of this uh uh what's really worrying, I think

We wanted to know more about this. Is climate change really a national security issue in the same way that we think about terrorism or nuclear weapons? And if so, what are our governments doing about it? We found out that here in the US, our national security leaders are very concerned about climate change. Here's Secretary of Defense Lloyd J. Austin III in April 2021. We face all kinds of threats in our line of work, but few of them truly deserve to be committed.

Existential. A climate crisis does deserve to be called existential. Rising sea levels and more frequent intense storms put individual families and whole communities at risk while pushing the limits of our collective capacity to respond. To better understand what officials like Defense Secretary Austin are thinking, we reached out to an expert in US national security. I'm Alice Hill. I am the David M. Rubinstein Senior Fellow for Energy and Environment at the Council on Foreign Relations.

Previously, I served in the White House for President Barack Obama as Senior Director for Resilience Policy on the National Security Council. And before that, I had a career as a judge in Los Angeles. Judge Hill started her time in government at the Department of Homeland Security, also called DHS. DHS was formed after 9 11 and is responsible for Americans' public security, so things like customs and immigration and FEMA.

the Federal Emergency Management Agency, which responds to national disasters like hurricanes and wildfires. President Obama signed an executive order ordering all agencies, including DHS, the Department of Homeland Security, to engage in climate adaptation planning for the first time. Well, there weren't many. This is two thousand nine at the Department of Homeland Security who wanted

to pin their careers to the issue of climate change. So I was the new person who had arrived at the department. And as I remember it, we're sitting around the table, the senior leadership, and someone says, Oh, give it to her. She's new. I assembled a task force from across the sprawling agency, and we asked the question in 2009. Does DHS need to worry about climate change? We spoke with scientists, policymakers, and quickly concluded, yes, DHS needs to worry deeply about climate change.

Judge Hill shared with us that there are three kinds of security risks we're going to face in a warming world. The first is that more people and communities are going to be hit by climate impact. And you can see that just in how we choose to build our homes and where we live. The fastest-growing land use form. In the lower forty-eight of the states is building in the middle of a forest or right next to grasslands. With increasing wildfire risk.

Those homes are at great risk of incineration. But more people are moving into those areas not aware of what they're facing. Very similar on eastern seaboard, people are moving into flood zones. Because they want to live next to the water, but they don't realize that rapidly we're gonna have bigger storms and more sea level rise, which will flood their homes. And as more of these things happen, more communities will find themselves without help.

Sadly, the pandemic has given us great insight in how this can unfold. We had never in the United States really planned to have a disaster in 50 states and six territories at once. So it introduced to us this idea that we could have multiple events draining our ability to respond. And if we don't have backups, the next community that's hit may be out of luck.

This brings us to our second kind of security threat. As we discussed in our episodes on sea level rise, a disaster can force people to need to find somewhere else to live, temporarily or permanently. Estimates are that 24 million people are internally displaced today, every year, worldwide, because of worsening natural hazards. Here in the United States we have displacement. When a big storm comes and homes are flooded, say after Katrina.

a diaspora of people from New Orleans. Similarly in California, after paradise was wiped out by fire. That town essentially moved in a few hours to a neighboring town, and that town welcomed them initially, but once it becomes real that New homes are needed. There was already a question of affordable housing. The kindergarten's gonna be f have more students than they ever planned for. The roads are more crowded.

There's some adjustment that needs to happen. And if you look across the globe and that's happening, that's putting pressure on communities. Now imagine that disasters like this have been happening one after the other for years. In fact, you're seeing that in our southern border, right here in the United States. we've had this challenge with increased numbers of Central Americans from what's known as the Northern Triangle, Honduras, El Salvador, and Guatemala.

This region is still dealing with the aftereffects of some terrible civil wars that lasted into the 1990s and which the US was involved in. That's left a legacy of poverty and violence that some people are desperate to escape. And climate change has made that bad situation even worse. If you peel back the facts, they've also had very severe climate impacts. A drought that decimated their crops, a coffee fungus. that flourishes in changed conditions that wiped out coffee bush.

Flooding and and that just happened. Two back-to-back hurricanes, and now many who don't even have a place to live are heading north to find better conditions. And here we're getting at the third kind of security risk posed by climate change. these events can be destabilizing for governments. If the government is ill prepared or doesn't respond in a way that inspires trust in The people, the government is ostensibly uh helping, it can drive them into the arms of bad actors. We saw this.

We saw that cartels were taking advantage of, for example, uh Mexican government's inability to provide basic necessities to the population. We saw the Taliban using it as a recruitment means. Uh we see corrupt individuals, the mafia in Italy using this as a moment to expand its influence as well as recruit.

For people who worry about our national security, this is the kind of threat they've always worried about. Terrorism, organized crime, violent groups vying for control of governments, they all have more room to grow when times are hard.

The good news here is that US military and intelligence agencies know that they need to deal with these threats. Pretty universally with climate change, it's recognized that there is a need for extensive planning so that people can understand that they can't just peg everything to what they've experienced in the past. That's probably the most difficult lesson for anyone to learn because we've all grown up with the assumption that So we need to have our signal. And then you can use those tools

and what they call scenario planning. I'll give you an example of that. one of the crown jewels, certainly, of the US military, if not the largest naval port in the world. But that early. is suffering from a rapid rate of sea level rise. So if you do a scenario which says Let's imagine we're in Norfolk, Virginia, and the seas rise two feet. Let's look at a map and see where that water could go. And then you think, okay, well, that means this base is flooded and that base is flooded.

people can't get here. How would that change our planning? What should we build now to have a better future? Then we move on to the strategic concerns. And that's where we're looking at what could happen in the world that would impact United States. Security. And that could be a flood, a devastating spread of a disease.

that's worsened by climate change. And then of course there's scenario considering if this leader fails, if he's pushed out of office, if there's a coup, what could happen? And imagining all these things. So we're as ready as possible. And Judge Hill sees this as a place where the State Department plays a critical role. The State Department deals with things like providing foreign aid and negotiating with other countries.

In other words, trying to prevent conflicts so that the military doesn't have to get involved. Climate change requires us to make much deeper investments in development overseas as well as diplomacy. Helping countries thrive so that their populations don't want to leave and You need to invest in their survive and In a warming world. And the way you do that is through working on increasing aid to those countries. Uh as well as helping them diplomatically.

So if we address the problem of running We can reduce the threats to conflict, but rather an area where we can enjoy global stability. So it's time we get busy and work hard to understand what the risks are and how we can shore them up.

That's the end of this episode, but if you want to learn more about climate and national security, and there is plenty more to learn, we're leaving some links in our show notes and on our Twitter at TIL Climate. We'd also love to hear your questions and your feedback. You can send us a message on Twitter or write to us T A L Climate at mit.edu. Thank you to Judge Hill for joining us and thank you for listening.
