CLIMATE CHANGE IN CALIFORNIA/COLORADO
[TAPE 4]
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04;00;36;24] To start, just say your name and how to spell it so it's on there for the transcriber.
ANTHONY WESTERLING
Anthony Westerling, ANTHONY WESTERLING.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04;00;58;19] And um, and your title here.
ANTHONY WESTERLING
I'm an assistant project scientist.
BILL BLAKEMORE
And your specialty?
ANTHONY WESTERLING
[04;01;04;13] Wildfire and climate.
BILL BLAKEMORE
Wildfire and climate?
ANTHONY WESTERLING
Yeah.
BILL BLAKEMORE
[04;01;07;16] OK, well, the basic question I have is, we're doing a series about global warming and its impacts. What can you tell us about the impact of global warming on the wildfire situation?
ANTHONY WESTERLING
[04;01;17;11] Well, you know, California in particular has a very diverse climate and a very diverse ecosystem, so there's a lot of variety here. That means that no one story is going to tell you about the whole state. But there are two common elements that are true for wildfire everywhere, and that's, is there enough fuel to burn? You have continuous fuel, you can get a fire that spreads to a large size. [04:01:40:07] And the other is, is the fuel dry enough to burn? So climate change effects both of those things. And one, one aspect is changes in precipitation and in temperature during the growing season effect the moisture available to grow vegetation that can later burn. [04:01:56:20] And the other thing is, temperature during the, the, uh, fire season itself, so during the summer typically, uh, drives wildfire risks. So the hotter it is the more likely it is to burn in some places, not in others. So, just to give you some examples, uh, if you're out in the desert here east of San Diego, you could see a place where there's very sparse vegetation, and normally it might not be able to carry a fire to a large size in the vegetation because it's not continuous enough. [04:02:28:06] But, um, if you get enough precipitation, for example, you can get a lot of grass that will grow, and cure out, and dry out during the, the summer, and, and then you can get a large fire. [04:02:37:13] You go up to some place like Yosemite and Sequoia, and you have these pine forests, they're really drive, the wildfire risks in places like that are really driven by temperature in particular. [04;02;51;06] Uh, and as you go up in elevation, snow is very important. If you melt the snow earlier in the year, or if you get less snow and more rain in the wintertime you get a much longer dry season during the summer, and that means you get a lot more opportunities for fires to burn, you have a longer time when vegetation can dry out. [04:03:10:21] And so, we're already seeing this to some extent around the west. We've had tremendous increases in forest fire risks, and forest.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04:03:25:02] Before you pick up with we're already seeing this around the west, I want to ask a point just to finish completing the dots. If it is true that, that global warming means, is often bringing us a lot more rain early in the growing season and a lot more drying out later. OK, ready? OK, so to complete the dot what is, what is, uh, the dots, what is, what is global warming and climate change doing to early rains and later drying?
ANTHONY WESTERLING
[04;03;50;16] Well, you know, it varies a lot in terms of precipitation. If you look at a broad range of these models, uh, you'll see that they're all broadly in agreement in terms of warmer future for, for the western United States. Now some of them maybe are warmer than others, but they all have, are in the same direction, and it's not that huge a spread in temperature. [04:04:12:16] But, when you look at precipitation it's a very different story, a lot of uncertainty about precipitation. So, some models are much dryer in, in a place like southern California, and others are much wetter in terms of how much precipitation you're going to get. [04;04;28;00] That part's really un-, unpredictable at this point. We can't say what's going to happen with precipitation. And, and so fire regimes, fire risks like we have here in southern California that are driven both by temperature and a lot of antecedent precipitation are very uncertain, we don't know, uh, whether it would increase or decrease under climate change, because we don't know how wet it's going to be. [04;04;50;21] But, if you look at some place like northern California, um, in the Sierra's, the coast ranges, places like that, is really strongly driven by temperature, and dry years tend to be both warmer and less precipitation. And, and so you get a really big impact from climate change in all the models that we've looked at in northern California, for example.
BILL BLAKEMORE
[04:05:13:21] So, so it's true in some places that, that global warming means that you're getting heavier rains early in the year when it's growing, and much hotter and dryer later in some places-
ANTHONY WESTERLING
You know, I'm not the person to ask.
BILL BLAKEMORE
[04:05:23:16] OK, OK fine. OK, good. So what have your projections, what are your, give us a sense of quantification of, of how much worse you're seeing-
ANTHONY WESTERLING
[04:05:34:29] Well what about what, what we're already seeing, and then we'll talk about-
BILL BLAKEMORE
Yeah, yeah, go-
ANTHONY WESTERLING
.projections.
BILL BLAKEMORE
What you're already seeing, In other words it's already, there's-
ANTHONY WESTERLING
[04;05;38;06] Yes. So, looking at the western United States, there's just been a tremendous increase in the frequency of large dangerous forest fires. And it's really been concentrated at sort of mid-elevations, or like around seven thousand feet in elevation, and uh, the worst place in terms of the biggest increase has been the northern Rockies. [04:05:57:13] And then the second after that is, is California in the Sierra Nevadas and the coast ranges of the northern California coast.
[OFF CAMERA COMMENTS]
ANTHONY WESTERLING
[04;06;13;08] OK, so the worst, uh, the worst that we've seen so far, the biggest increase has been in the northern Rockies, concentrated around seven thousand feet in elevation. And after that comes California, uh, especially the Sierras and the coast ranges along the north coast. [04:06:30:10] Uh, it's been a tremendous increase in both places, and it, and those, those two account for, for most of the changes in the west. There's been a lot of discussion about the effects of, of um, a century of land management on fire risks, because when you suppress fires for a long time in some places you get an increased fuel load, you get more trees growing close together, you get more shrubs and things like that, and it can carry fire to a large size. [04:06:59:08] But, uh, that effect is completely overwhelmed by, by the temperature signal that we're seeing. What's happening is that the snow is melting earlier in the year on a, at very regular intervals now, and uh, we're getting much longer fire seasons, it dries out much more than before, and we just get tremendous increase in, uh, in the number of large wildfires in the mountains of the west.
BILL BLAKEMORE
[04:07:26:24] And you can, and you can just complete the circle there for us with global warming, about why, why it appears-
ANTHONY WESTERLING
[04;07;32;02] So, if this is, you know, if you ask any climatologist, they're going, they're not going to be able to tell you what, were these temperature increases, these early springs driven by climate change or not, just like they can't say any specific storm was caused by climate change. [04;07;05;22] But, if you think about it as an analog for the future, it tells us that we're going to have much greater fire risks, we're going to have a lot more large forest fires tan we do right now.
BILL BLAKEMORE
[04;07;58;26] Because the snow melts out sooner?
ANTHONY WESTERLING
Because the snow melts out sooner it, you have both a longer dry season, that means that, that the vegetation is not going to be buffered by the moisture in the snows and then in the soils. [04:08:11:28] And then subsequently it also means that, that you have just a longer time when an ignition can cause a fire. So, you get a much longer fire season, and much more intense.
BILL BLAKEMORE
And for the public who's a little bit confused about fires, wildfires, they're good, they're bad, they replenish the earth, they don't replenish the earth. We saw Yosemite come back, etc., etc.
ANTHONY WESTERLING
[04;08;32;08] Well, if you have a, a system that's adapted to, say, burning every fifty years, or burning every hundred years, and you start burning it ever ten years, you're going to completely change the character of that ecosystem, it's not going to be this iconic forest like you have now, it'll be something else.
BILL BLAKEMORE
[04:08:49:29] And what about the impact on human development?
ANTHONY WESTERLING
[04;08;51;11] Well, the biggest problem in California, the biggest challenge for the state going forward is that some of our fastest growing areas in terms of population and development are in the path of what we see, where we see some of the biggest increases in fire risks in the future. And so places that account for a very small percentage of the state's population now, uh, really are driving the increase in, in property losses in the state from wildfire. [04:09:19:18] And those are the places that are going to have the biggest increases in fire frequency in future, uh, driven by temperature increases from climate change.
BILL BLAKEMORE
[0:11:26:27] I didn't quite follow that. Why are they driving it? I mean they didn't, you said the places that have the least population.?
ANTHONY WESTERLING
[04;09;32;06] OK, so they have, presently they account for a small percentage of the state's population, but they're the fastest growing, and, and they're-
BILL BLAKEMORE
Start that from the beginning. When you say "they" you're talking about what?
ANTHONY WESTERLING
[04;09;42;06] So the Sierra, um, the Sierra, Sierra Nevada foothills, and sort of the expanding ring of wild and urban interface around the core, you know, Bay Area metropolitan area in northern California, very rapidly growing populations, rapidly growing development. And it's dispersed around its edges, so you're sprinkling expensive homes in places that like to burn. [04:10:07:19] And they're going to burn even more when you increase the temperature. And the damages from. The vulnerability to the state's economy from building another apartment building in San Diego is negligible, whereas if you build another house out in the Sierra foothills, you're dramatically increasing the state's economic vulnerability to climate change impacts from, through wildfire. Is that.?
BILL BLAKEMORE
[04;10;31;27] Exactly, helping us understand the economic impact of wildfires is a very interesting point.
ANTHONY WESTERLING
Right. So, so part of this, this uh, future risk that, that the state is going to have to manage is, how do we control, or do we not control development in these areas? [04;10;46;28] Do we allow the wild and urban interface, that's these homes sprinkled throughout, uh, what are currently, you know, undeveloped areas, to grow? And that's a very difficult issue, because on the one hand you increase the state's vulnerability, but on the other hand that's the use that people want to make on that land, and if they have to forego that, that's also an economic impact for the state. [04:11:10:20] So either way, it's a lose/lose situation. You don't develop in those lands, or you do and you, you have much greater costs and much greater risks.
BILL BLAKEMORE
[04;11;19;14] So both for the wild environment, the ecosystems, and for the human environment, global warming is causing much greater likelihood of wildfires.
ANTHONY WESTERLING
That's right. And when you combine that with population growth and development in these currently lower density areas, uh, it, it's going to be a tremendous management problem for the state in the future. [04;11;41;09] For one thing, fire managers have very different options when there are homes and people living in an area and when there aren't, in terms of how they can manage wildfire. [04;11;50;13] They can take decisions that are more strategic, thinking about what are, what are the resources, the natural resources that they want to preserve, and what can, um, they do in terms of lighting a back fire, for example, and they'll just let one area burn and focus their resources somewhere else. [04:12:08:24] When you have a lot of homes in, in an area that's, that's prone to large wildfires, they take a very different strategy. They, they try to protect islands around development that has significant value. [04;12;21;10] And, and so you get larger fires because they have to focus their resources on protecting these little islands within the, the wildfire rather than fighting the wildfire itself.
BILL BLAKEMORE
[04:12:32:15] And how sure are you that it's going to keep warming?
ANTHONY WESTERLING
I just listen to what the climatologists tell me.
BILL BLAKEMORE
And what do they, and what is your assessment of what the climatologists are telling you about that?
ANTHONY WESTERLING
[04;12;41;21] Well, what we see on the ground is that it's already happening, it looks just like what they tell us to expect to see. So, from my own parochial point of view it sure looks like climate change to me.
BILL BLAKEMORE
[04:12:53:11] And what is your general expectation from your specialty of whether or not you expect it to keep going and accelerating?
ANTHONY WESTERLING
I'm sorry, can you rephrase that question? [LAUGHS]
BILL BLAKEMORE
Is this a problem, is this a problem from what you're being told and from what your general understanding is that's very likely to keep going and getting worse?
ANTHONY WESTERLING
[04;13;09;05] Yeah, I think this will continue to get much worse.
BILL BLAKEMORE
Much worse?
ANTHONY WESTERLING
Yes.
BILL BLAKEMORE
I mean.?
ANTHONY WESTERLING
[04:13:16:24] Well because, think about it, as you move up in elevation, you'll have some place in the west that's just a little bit colder than, than the threshold where the snow would melt. OK? And so that area is very vulnerable right now. [04:13:33:18] And so when we get a warm spring right now, that area melts sooner than it would otherwise. You go uphill a little bit further and the impact is, is not so clear, because, because there's more temperature that you can use up as the temperature increases before you're going to melt the snow. Right? So, you get a very sudden response in places that are vulnerable now, that are close to the threshold where the snow's going to melt. [1:14:00:08] But there are a lot of parts of the mess that are not burning now that might burn in the future as temperatures continue to increase. And so the problems that we have in the northern Rockies around seven thousand feet in elevation, and in parts of California, may become much more common. You know, maybe they will spread to higher elevations. [04;14;17;16] Maybe we'll have a problem in the northwest where we have not had as much of a problem now because it's much wetter than it is here.
BILL BLAKEMORE
[04;14;22;29] So, you're also an economist?
ANTHONY WESTERLING
I'm also an economist.
BILL BLAKEMORE
You're general sense of the economic impact, therefore, from all the fires that, uh, global warming is bringing?
ANTHONY WESTERLING
[04:14:31:09] You know, I think that the biggest economic impact is going to be from the sort of synergistic effects, the combined effects of different things. You know, we generally tend to look at things with blinders on, we'll look at just the effects of climate change on wildfire, or just the effects on the water system. [04;14;46;27] Well, if you burn out a water shed, if you burn out, say, the west slope of the Sierra Nevadas, you have the ecological impacts, you have the impacts on, say, people's enjoyment of the, the scenery and fishing and things like that, you have the impact on people's homes, but you also are going to get more run off. It's, you know, the, the problem with climate change for water resources is that, that uh, if you get an earlier spring, you get earlier run off, and you can't manage the reservoirs to captures as much of the water as you can if it runs off later in the year. [04:15:21:24] Well, if you have a lot of fires in the slopes above that reservoir, you're going to get more erosion, you're going to get more sediment run off. That, that creates additional complications for managing these resources. You're going to have flashier run off, you know, because uh, it won't be retained by the roots in the soil because there won't be as many roots in the soil. [04:15:46:16] And, and so all of these problems we really have to get a sense of how they build on one another, and that's an area that has not been sufficiently explored yet.
BILL BLAKEMORE
[04;15;55;08] And if the temperature and the carbon keep going up and up and up.?
ANTHONY WESTERLING
[04:15:59:29] We'll keep passing thresholds where we start to see effects that we didn't anticipate, or that, that, you know, occur rather suddenly rather than sort of gradual changes, like the wildfire in the western United States, it really just kicked up in the mid 1980's. There was nothing going on for decades, and then, and then just the next year it was a different system entirely, and it's been like that for almost twenty years now.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04;16;43;13] So fire and carbon?
ANTHONY WESTERLING
OK, so I can't remember the exact number off the top of my head, I can give it to you later.
BILL BLAKEMORE
Just your-
ANTHONY WESTERLING
Something in the order of twenty to forty percent of the carbon uptake in the United States is potentially occurring in these mountain forest of the western United States. [04:17:03:10] And when people talk about, um, you know, the growth of forests in North America, they usually think of the east coast and, and southern piedmont as places that have, uh, increased forest cover since the last turn of the century, the 1900's. but, and maybe that hasn't occurred to the same degree here in the western United States, I'm not certain about that. [04:17:24:00] But, but what we do know is that the western United States, the mountain ecosystems are an enormous carbon pool, and if we start releasing that carbon because we are increasing temperatures and therefore burning more regularly, we're going to release a lot of carbon that's currently stored in these forests, and that's going to be a positive feedback, it's going to exacerbate the, the whole problem with climate change.
BILL BLAKEMORE
[04:17:48:01] Right. Did you hear that all right? It's a very important thing he just said.
[OFF CAMERA COMMENTS]
ANTHONY WESTERLING
[04;18;02;02] The percentage of carbon uptake accounted for by western mountain forests for the United States is something like on the order of twenty to forty percent, and that ecosystem, the western mountain forests in the United States are an enormous carbon pool. They're storing carbon in the trees, in the, in the soils, and as we raise temperatures, uh, a couple of things happen. [04:18:33:22] And a colleague of mine, David Shimmel [PH] has found that it increases the, it decreases the ability of the ecosystems to uptake carbon in the years that it's warmer, when you get a warmer spring. But it's also the case that, that uh, as you warm it up, it burns off, and, and the more frequently that it burns the more, the less carbon it's going to store, and that means a very large positive feedback on climate change where, where climate change gives you warmer temperatures, gives you more frequent fires, which gives you more carbon release from the forests and soils, which is a positive feedback to climate change.
BILL BLAKEMORE
[04:19:17:18] So it gives you both more carbon back into the atmosphere and less carbon taken out of it because there's less plants to take it out?
ANTHONY WESTERLING
And that would also be something to consider as well. You might want to ask Dave Shimmel before you, before you, you say anything that I said about him.
BILL BLAKEMORE
[04:19:32:24] This sounds pretty dire in the next, you're talking about something that we're going to see increasing not in a few hundred years, but increasingly in the coming decades.
ANTHONY WESTERLING
[04;19;40;25] Yeah, I mean, this is already something that we're seeing happen, I think.
BILL BLAKEMORE
So this is going to effect the life of today's toddlers by the time they're middle age.
ANTHONY WESTERLING
Yeah, my daughter.
BILL BLAKEMORE
Your daughter. You have a daughter?
ANTHONY WESTERLING
[04:19:54:13] Uh-huh.
BILL BLAKEMORE
How old? A kid?
ANTHONY WESTERLING
Uh, she's twenty-one months.
BILL BLAKEMORE
Twenty-one months old.
ANTHONY WESTERLING
[04;19;57;26] Yeah, and I have no idea what kind of, what kind of world she's going to inherit.
BILL BLAKEMORE
Are you worried about it?
ANTHONY WESTERLING
Of course, any rational person.
BILL BLAKEMORE
Scared?
ANTHONY WESTERLING
[04;20;14;22] Concerned.
BILL BLAKEMORE
What do you think is, do we have a chance of stopping it in any way, controlling it?
ANTHONY WESTERLING
[04;20;23;04] My own subjective opinion is that we still maybe have a window of opportunity, but it's something that has to be dealt with in this generation. If we put it off to our children, it'll be too late. That's, that's my opinion.
BILL BLAKEMORE
And that means drastically cutting carbon emissions?
ANTHONY WESTERLING
[04;20;46;27] That means drastically cut, cutting carbon emissions, yes.
BILL BLAKEMORE
Oh good, more good news.
ANTHONY WESTERLING
OK?
BILL BLAKEMORE
Anything else?
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04;21;43;19] So, so for people who live in the San Bernardino foothills, for example, if they've been listening to all kinds of voices that are still out there, credibly, about climate change, can you just add a sentence or two to tell them, and they said, why should I care that the climate is changing?
ANTHONY WESTERLING
[04:22:01:04] Well, they probably moved to that place because they liked it the way it is now. If you change the climate you're going to change the ecosystem, the weather, everything about the place that, that might have attracted them in the first place is going to be effected.
BILL BLAKEMORE
[04:22:15:24] And your not talking about a century from now.
ANTHONY WESTERLING
No, probably not.
MAN
But specifically with the wildfire threat, I mean-
ANTHONY WESTERLING
[04:22:24:11] Well, you know, wildfire in San Bernardino foothills, for example, San Bernardino, is a very different thing from wildfire in the Sierra Nevadas or northern coast, it's much more driven by, well it depends what kind of ecosystem you're in. You know, the coastal chaparral, for example, the shrub lands in California, uh, are really driven by Santa Anna winds, the wildfire risks there are really driven by Santa Anna winds. [04:23:52:18] And that's more of a, you know, very short term meteorological condition rather than thinking about temperature or the antecedent precipitation, and that's something that's very hard to, to understand how it might change coming out of a climate change simulation.
BILL BLAKEMORE
[04;23;07;06] You mean because it's possible, for example, that climate change in the San Bernardino foothills for all you know could mean more rain there for a while.
ANTHONY WESTERLING
It could, or it could mean less, I, it's harder to say.
BILL BLAKEMORE
Less rain and more fire. Right, so-
ANTHONY WESTERLING
[04:23:22:26] I mean, if you warm it up and you get less rain, you get less vegetation over time in a place like that, and you're going to have maybe lower fire risks, especially at lower elevations, then you might have now, because it would become more like a desert and less like it, like it is now.
BILL BLAKEMORE
[04;23;39;25] But we haven't, here's a question, seen many more of these fires in foothills like that, where there's suburban-
ANTHONY WESTERLING
Yeah, well, part of the problem is that the suburban settlement has expanded into areas that, that burn, and those fires are not at all unusual for, for this place.
BILL BLAKEMORE
[04;23;58;05] Right, but anything, you're saying generally from seven thousand feet up you're seeing climate change effects?
ANTHONY WESTERLING
[04;24;03;26] That's right, in mid to upper elevations, seeing, and it's really focused, you know, like six to eight thousand feet elevation-
BILL BLAKEMORE
It started in the eighties, mid-eighties?
ANTHONY WESTERLING
[04;24;12;27] Mid-eighties, yeah.
BILL BLAKEMORE
Oh, oh, important thing, was Yosemite part of that pattern? Yeah, the big Yosemite fire was in the mid eighties.
ANTHONY WESTERLING
[04;24;21;16] Yeah, it's all-
BILL BLAKEMORE
Could you just say something about, for example-
ANTHONY WESTERLING
[04;24;25;16] You can't say anything about one specific fire, you know. It's looking at the statistics of all of them together.
BILL BLAKEMORE
[04:24:30:12] Right, In other words, it's-
ANTHONY WESTERLING
That means I'm not going to say. [LAUGHS]
BILL BLAKEMORE
That's one of the semantic problems we're finding in covering this. It fits the pattern-[BREAK IN AUDIO]
[OFF CAMERA COMMENTS]
ANTHONY WESTERLING
[04;24;44;24] Well the answer for-
MAN
Any time, go ahead.
ANTHONY WESTERLING
.for southern California would be that they do not at all fit the, a pattern that you would attribute to climate change.
BILL BLAKEMORE
[04:24:49:17] And that would be for the fires you're having in southern California?
ANTHONY WESTERLING
That's right, the uh, coastal southern California looks just like it's looked for a long time, it just, it accounts for less than one percent of the change in, in fires that we would attribute to changes in-[BREAK IN AUDIO] ..by Santa Anna wind events.
BILL BLAKEMORE
Right.
ANTHONY WESTERLING
[04;25;11;13] And, and so nothing about this system is particularly vulnerable in the short term to temperature changes, whereas at higher elevations where you get, for example in the northern Rockies you have a big area that's right at an elevation where it's just below freezing for a large part of, you know, late winter, early-[BREAK IN AUDIO]
[OFF CAMERA COMMENTS]
[END ANDY WESTERLING INTERVIEW]
[BEGIN MAT FRATUS INTERVIEW]
BILL BLAKEMORE
[04:38:17:21] So what do you, what do you remember from, from around here? What was happening?
MAT FRATUS
Well, the day that the fire transitioned up the hill and crested over the top and immediately went down a chimney up over in this area here, and uh, the vegetation was so thick, there was huge stands of trees that had already been impacted by the bark beetle, and really nothing to stop the fire from coming down, to the point that, because this road has no exit, there's only one way in and one way out. [04;38;44;27] And we really, none of our tactics that we were using were really slowing the fire down. Uh, we essentially had to pull out of this area and just resign that these houses would just have to burn.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04;39;15;08] So, tell us, tell us more about what we're looking at here, what happens, and, and what the, what the information is.
MAT FRATUS
[04;39;20;16] Well, this particular area is a, kind of an outskirt of Lake Arrowhead, an area known as Cedar Glen, and, and Hook Creek Road area here. Um, a lot of houses, although you can't tell now that this was actually a very densely populated area, um, because of the, the types of vegetation, because of the weather patterns that we were having, uh, the fire came through here at such a rate that everything that we had tried to do to stop it really was, for the most part, ineffective. [04;39;47;20] And you have to keep in mind that even though, uh, we have very good fire protection in this area on a normal day, we had fires burning throughout the state, so the resources we were working with were limited to start with, but the type of fire behavior we were dealing with was really unlike what most of us had seen. [04;40;02;05] I had talked to people who had been in the fire service their entire career, and not only this fire, but fires in proceeding years, because of the drought, because of the fuel conditions, they produced, uh, fire behavior, flame links, intensities that we had never really experienced before, and everything that we had to throw at it we did, and it just seemed to burn right through us. [04:40:21:02] So, we were taking a defensive posture in here, uh, for reasons of safety. We knew that we couldn't make a stand in this area and be effective. So uh, it was very difficult for a lot of us, I was born and raised in this area, and to see this entire area burn in my, in my lifetime, I've never seen a fire come through here of anything of that magnitude. [04;40;39;24] Uh, so the best we could do was try to get over one more ridge, uh, over to the next ridge over is where we finally made a stand, and uh, quite honestly, uh, as, as much as our, I think our tactics were effective ultimately what helped us win this fight was the weather change, uh, we had a low pressure come in, it actually began to rain, actually began to snow within a couple of days after this burning, and I have to wonder if that had not happened how much farther this fire would have gone, how much more devastation we would have seen.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04;41;13;02] So first just say your name, your position, your title, how you spell it.
MAT FRATUS
OK. Mat Fratus, MAT, one T, Fratus, FRATUS, and I'm a division chief with the San Bernardino with the San Bernardino City Fire Department.
BILL BLAKEMORE
[04;41;25;02] And how long have you been, in one way or another, connected with the fire department?
MAT FRATUS
About twenty years.
BILL BLAKEMORE
About twenty years. And you grew up around her?
MAT FRATUS
[04;41;30;27] Yes I did. Um, born and raised up on the mountain here, my kids are the fifth generation of my family that have been living up here, so we have a lot of strong roots in this community.
BILL BLAKEMORE
[04:41:41:01] So what did it feel like to see your own community burn?
MAT FRATUS
Uh, the best way I can describe it is just surreal. Uh, driving through areas that I've known my entire life that are literally going up in flames. The house I grew up in, uh, houses, every house, uh, probably within an eighth of a mile, uh, of it had burned by the time I came up on the hill. [04;42;02;08] It was just, it was very difficult to see. Areas like this, people's houses that I knew who lived there, who used to live there, uh, now just piles of rubble.
BILL BLAKEMORE
Did you ever think you would see anything like this when you were growing up?
MAT FRATUS
[04:42:14:06] I really didn't. Uh, you kind of learn to live with fire when you live in a mountainous area like this, in an urban interface area, but uh, in all that time it had never really threatened the, the structures to this extent. Never had it come this close. [04;42;26;07] And this time not only did it come close, but it just roared through large sections of housing.
BILL BLAKEMORE
And the old timers, did they tell you when, the last time they had seen a fire like this?
MAT FRATUS
[04:42:35:06] I don't know anybody that had ever seen a fire of this magnitude. We've had some large ones, but uh, over time the mountain has become more and more populated, uh, and the, the level of, of interface has increased, uh, but nobody that I know of had ever really seen it burn to this level, this many houses, do this much devastation and impact.
BILL BLAKEMORE
[04:42:54:25] So you're a fire chief, you're a professional fire chief, fire fighter?
MAT FRATUS
Yes.
BILL BLAKEMORE
And I, and you're talking about global warming? That's a whole different field. How come you fire, you're not the first one we've run into, how come you fire chiefs are nowadays talking about global warming?
MAT FRATUS
[04:43:09:03] Well, there's a lot of evidence that's indicating that there is, that global warming itself is having a great deal of impact on the intensity and the frequency of the fires that we're having. Uh, clearly we're having more people move into the interface areas, and that's certainly one element of it. [04;43;26;11] But, as we begin to see the fires each year grow in intensity, um, it becomes more and more difficult to suppress them, and then it becomes somewhat of a vicious cycle, because as these fires grow they actually contribute by their products of combustion into the global warming, uh, process again. [04:43:42:02] So it's very difficult to try to find the balance, but uh, we do know that even prior to the 2003 fire season, in the years prior to that, we are experiencing warmer weather, drier fuel conditions, uh, drought, all of which were contributing substantially to the kind of fires that we were having and the intensity that they were coming at.
BILL BLAKEMORE
[04;44;01;05] What are some of the other things that are related, sometimes, to global warming, that are elements that, coming together, can contribute to making it a worse fire?
MAT FRATUS
[04;44;09;08] Well the, the warming, um, the, the drought that we experienced, and this of course, you know, you start looking into the chain in the ecosystem, and how this happens, uh, we had experienced several years of drought before the 2003 fire season. In the San Bernardino Mountains one of the issues that that brought about was an infestation of the bark beetle. And this particular species of bark beetle has always been present in the San Bernardino Mountains, but the, the tree's natural defense to, to ward off these bark beetles is to create pitch, which pushes them out of the tree. [04:44:41:16] But it takes, uh, enough moisture to create that sap and the pitch to push them out, and because of the drought they were unable to defend themselves, which just made a perfect breeding ground. [04:44:51:10] So, what had happened in this mountain, even before the fire, maybe even as devastating as the fire in some ways, is the fact that we had hundreds and thousands of trees, and we're talking hundred year old trees that were dying in a matter of months. [04;45;05;16] So, you would look across the forest and what you would see is just fields and fields of dead trees. And of course we knew that if we were to have a fire in these conditions, uh, it was going to be devastating. Uh, we weren't even sure how bad it could be. [04:45:19:20] When you take a hundred foot tree that's dead and you put it together with a hundred more hundred foot trees that are dead, and then you light the fuse underneath them, um, it's basically, it's just a powder keg.
BILL BLAKEMORE
[04:45:30:09] So what was, what would it have been like if we had been standing here in the midst of the worst fire, in this little cauldron of a valley here?
MAT FRATUS
[04;45;34;16] Well, I watched this area burn from a ridge that was farther back over this way, and I watched it right up until probably, there were still houses burning in here around midnight, and it was absolutely intense. Uh, we wandered down some roads trying to get in on the ridges on the other side, and the, just the sound of the fire was deafening. You had to, to yell to the person that was standing five feet away from you, and you couldn't even see the fire yet. [04:46:00:13] This was just the noise from the fire. Uh, so the, the amount of fuel that it had to burn, and the intensity that it had that, when it came over this ridge, uh, was just phenomenal.
BILL BLAKEMORE
Hell on earth.
MAT FRATUS
[04:46:12:04] I would describe it as that, yes.
BILL BLAKEMORE
Noise from a fire?
MAT FRATUS
Yes, I've heard it described before by people, they describe it as a freight train. My best description was, if you've ever stood at the base of a very large waterfall, uh, that was what it sounded like. It was just a constant roar, and again, so loud you couldn't speak to the people next to you without yelling. [04:46:34:21] And yet the fire was still in a place you couldn't even see it, it was that far away. That was how much, uh, intensity it carried with it as it went through here.
BILL BLAKEMORE
[04:46:41:25] And all basically because things were just too dry, so it brought in the beetles, that made it drier, and it made it even drier, so when it caught fire it was even drier.
MAT FRATUS
[04:46:48:15] Uh, that is a, a big part of it. Uh, there's also a lot of, another element that we think impacted this was the forest management policies. Uh, we have really, as, as a fire service it's been a, a hundred years of suppressing one hundred percent of all the fires, and in this area in particular they're very sensitive to cutting any trees. Even property owners are not allowed to cut trees on their own property. [04;47;12;20] So, the forest has to be allowed to take care of itself. The forest is going to stay healthy one way or the other, and a healthy forest is not too dense with trees. This forest became unhealthy because it was too dense with trees, and if you, you can only, uh, suppress the natural cycle of the forest for so long before it's going to do what it needs to do. [04;47;32;11] The bark beetle was part of that, and ultimately the fire was part of that as well.
BILL BLAKEMORE
[04;47;36;05] Now can you be sure it's global warming that has caused this recent drought that brought in the bark beetle that brought in the dryness?
MAT FRATUS
[04;47;41;02] Well, uh, in my profession I would not, uh, say that I, I am sure that I could offer scientific evidence, but what I do know is, uh, for myself, I've been in the fire service for a while, I know many others that have spent their entire careers in the fire service, and there is certainly something that is different in the intensity and the frequency of the fires that we're experiencing, and all indicators, and there is some strong evidence that this is a trend that we can expect to continue. [04:48:08:16] Uh, we're looking at our fire season 2006 right now, and we're gearing up for another intense fire season in the, uh, the southern areas. Even as we speak they're having intense fires in the Texas/Oklahoma areas, areas where you don't typically have large conflagrations where they're burning through towns and so forth. But this is something that we're seeing on a much more regular basis than we did before.
BILL BLAKEMORE
[04;48;29;12] So maybe the land is a little bit more sensitive to drying for fires than people had thought?
MAT FRATUS
Uh, that would certainly be one explanation for the conditions that we're seeing.
BILL BLAKEMORE
[04:48:39:27] And what are you hearing in general? I mean, I know you're not a climatologist, and we're not going to represent you as one, you're a firefighter. But what are you guys in general hearing about global warming and the likelihood of it just continuing to get worse?
MAT FRATUS
[04:48:52:25] Uh, well it wasn't something originally that we ha really looked at as a, a causal factor for these elements that we're seeing change, and the way that the fires are coming about. But uh, in absence of other things, more and more it really points, uh, to global warming as at least one of the significant elements that's causing this change in the fire-
BILL BLAKEMORE
We're, and we've been talking to climatologists, and they tell us that the carbon in the atmosphere that they've been measuring since '58 is just inexorably going up, and every year it goes up a little bit more. [04;49;19;13] You add to that carbon with a fire, of course, but to get, for all reasons the carbon is continuing to go up, which means more global warming, and they don't see an end in sight yet. And the carbon stays in the atmosphere a hundred years. [04;49;31;29] What is the, how do you, how does that make you feel?
MAT FRATUS
[04;49;35;15] Well, any time there is a change like that in the climate it's going to impact, uh, the fires, the wild land fires. Um, the things that we really look at, I mean, the, the fuels themselves are going to be impacted, that's one of the significant factors that we use to calculate how intense something will burn, or how readily it will burn. Um, the weather patterns are also going to have a huge impact, not only while the fire is burning, but also, you know, what kind of a winter are we having, what kind of a summer are we expecting. [04:50:06:18] This particular winter we were very dry in January and February, so our grass crops came up early. Then it started to rain in March and April, it was almost backwards of what a typical season would be. So now we have the equivalent of two grass crops that are coming up. [04:50:20:12] When they dry out in the spring and summer we're going to have a very intense fire season. So all of those things are certainly going to impact what we can expect to see in the wild land firefighting front.
BILL BLAKEMORE
[04;50;28;21] And what about snow pack and early snow melt? How, does that effect it further, so that the water runs off before summer's over?
MAT FRATUS
[04:50:37:04] Uh, well, certainly those would be some of the impacts of drought or, or lack of. Um, some of the broader things we have to look at, which occurred after several yeas of drought we had the most devastating fire, the San Bernardino, or San Bernardino National Forest had ever experienced. The following year we had record rainfall. Well, because of the fire the previous year, this caused record floods, uh, we had very devastating floods that impacted not only the mountain areas, but the front country area, the city of San Bernardino, we had several fatalities because of that. [04:51:08:05] So it's never really one single event, there is generally several things that are going to lead up to it and there will be several byproducts of an event like this, and most of them have been very devastating.
BILL BLAKEMORE
[04:51:19:21] Huh, the worst kind of, the worst kind of season. And when you have a burned off area like this, does this increase run off?
MAT FRATUS
Yes, it does. The natural vegetation, once it grows into the soil, actually holds the soil back, so you can, the ground can withstand a substantial amount of rain and not have the slough of the top soil. [04:51:39:29] Once all that vegetation is burned away, you immediately lose the top soil. And this is an element of the intensity of the fires. When we do controlled burnings to try to regulate the vegetation, we do it at a very low intensity, so you burn off the surface fuels, but it allows for the fuels to grow back at another time, relatively quickly, but it does thin it out. [04:52:01:07] When you let it grow for years and years and years and get thick, and then you have an uncontrolled wild land fire like the one we had in 2003 go through, it burns it right down to the rocks. [04:52:10:05] It essentially destroys the vegetation, takes it many more years to grow back. so, for those years, while it's growing back, you're going to be susceptible to, uh, devastating floods on a fire like this size.
BILL BLAKEMORE
[04;52;20;06] And if it keeps warming, and the warming accelerates like most of the climatologists are saying it will.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04;53;02;07] So if the global warming keeps accelerating as the climatologists are telling it will, it's going to keep going up, because the carbon is going to keep going up, and then it's going to start going up faster and faster, that sounds to me like you are going to be fighting for the rest of your career an ultimately unwinable battle.
MAT FRATUS
[04;53;20;04] Well, if in fact the, uh, the changes in the fire behaviors and the intensity of the fires that we're seeing, at least in the southern region here are attributed to global warming, if that is the case, um, and it appears that global warming is an issue that is not going to subside or go away any time soon, it is absolutely reasonable to assume that we are going to see fires, uh, what we thought was the anomaly will soon become the rule, which will change the way that we have to attack them. [04:53:47:21] Um, it will change the amount of, of fires that we'll just have to let burn, and unfortunately could create greater damage than we've seen in the past.
BILL BLAKEMORE
And add all that much more carbon to the atmosphere.
MAT FRATUS
[04;54;00;09] That is part of the vicious cycle of the global warming and its impact on wild land fire.
BILL BLAKEMORE
Everybody we're interviewing we're asking this: what's the solution?
MAT FRATUS
[04;54;10;10] Well, uh, that I really don't know. I mean, from a firefighter's perspective, uh, I think our biggest thing is that we're hoping that a solution is found. Um, we know that, uh, you know, once a wild land fire starts, as much as it contributes to it, there's not really much more we can do than, than just try and suppress it. But uh, as far as, you know, the clear answers, I'm sure, are going to be social, they're going to be technical, there's going to be a lot with it that's going to have to change if we're going to reverse this trend.
BILL BLAKEMORE
[04;54;38;24] Everybody we, we're also asking everybody we talk to, in your gut, how bad do you imagine it getting? I mean, I don't know if you have kids, but when today's kids are, you know, in middle age, I mean, you've already experienced hell on earth, and some climatologists are saying a lot of the human race is going to experience hell on earth. You see it in these fires. How, in your gut, how bad do you think it could be in fifty, sixty years?
MAT FRATUS
[04:55:01:00] Well, it, it's very difficult to tell. Um, I, I would like to think that we would be able to reverse some of the trend. However, under the scenario that, that things don't change, and it continues to escalate, um, we probably won't even recognize the way that we address the fire situation in fifty years compared to what we do now. I mean, for right now for us it's a surprising change. Uh, for those that will come after us it will just be the way they have to do business, and uh, there's really, I mean, you can only do so much as a fire service to put a fire out. [04:55:35:15] At some point you just have to stand back and let it go. And as the interface continues to encroach in, into the wild land, and we have more and more houses built in areas that are prone to fires, uh, you, there's nothing much that you can do but stand back, keep your people safe, try to suppress it as best you can, prevent it as best you can, but they're going to burn, and there's going to be damage.
BILL BLAKEMORE
[04;55;57;01] All right.
MAN
I was hoping you could just give us a quick summary of this fire in terms of lives lost, houses lost, acreage.
BILL BLAKEMORE
[04:56:04:04] Looking at me, of course.
MAT FRATUS
OK, yeah.
[OFF CAMERA COMMENTS]
MAT FRATUS
[04;56;12;17] The old fire was one of several fires that, uh, began to burn in late October of 2003. Um, because of that resources were stretched thin all over the state. This fire ultimately burned into another fire that started a few days sooner, the Grand Prix Fire, and collectively as they grew together it burned about ninety-three thousand acres, which is the largest fire in the history of the San Bernardino National Forest. [04;56;36;11] Uh, we had several structures lost up on the mountain top, we had even more structures lost down in the city of San Bernardino, over a thousand residences were lost just in this fire alone, in addition to multiple outbuildings, commercial buildings, vehicles, and so forth. Uh, we had several thousand people actually displaced, had to find temporary shelter, and some of them permanently displaced as their homes were burned down. Um, it definitely changed the face of, of operations not only up on the mountaintop area here, but in the city itself.
BILL BLAKEMORE
[04;57;11;25] Did you, uh, anybody ever put a dollar figure on it?
MAT FRATUS
I don't know if they have finished putting the dollar figure on it. The cost of this fire is still growing in some ways. These, now more indirect ways, uh, direct costs of the fire, of course, you know, the suppression cost, the costs to the housing people, and so forth, but the cost of rebuilding, cost of, uh, jobs that were lost, cost of businesses that will never rebuild, those are costs that will really be, uh, it will take a long time to really figure how much that's cost to communities.
BILL BLAKEMORE
Were, were there fatalities in the fire?
MAT FRATUS
[04;57;45;22] There were, um, indirect, and you know, and just for off camera stuff, those slides that I gave you have got all the statistic stats.
BILL BLAKEMORE
That's great.
MAT FRATUS
[04;57;53;11] I don't want to contradict them, I don't have a lot of them off the top of my head, but they'll be there for you to use.
BILL BLAKEMORE
OK, great. OK, great.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04:58:04:08] My goodness, this is, what is, what are we looking at here?
MAT FRATUS
Well, what we're standing in now is the foundation of what once was a house. And uh.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
Just tell us all about this.
MAT FRATUS
[04:58:15:09] Well what you're looking at now, uh, is the foundation of what was probably a, uh, a fairly large house. One of the things about a house once it burns down, it's almost kind of an optical illusion, you don't realize how big the house was just based on the, the foundational area, which is all we're looking at here. [04:58:34:20] But, as you see here, uh, up across the ridge, in fact just about everywhere you look up here, you'll find foundations that represent, uh, at one point, what was somebody's home, along with everything that was in it. And as you look through some of the ashes you can see, you know, melted aluminum and so forth, these were everything from windows to personal belongings, to uh, irreplaceable effects. [04;58;55;00] And when you multiply this by the hundreds of homes that were lost in this fire, uh, it's really very sad to see this happen.
BILL BLAKEMORE
[04:59:01:09] And all this timber, the lumber that's still here, that was what was basically bringing the fire in.
MAT FRATUS
[04:59:06:23] Yes, it was. And while those trees were burning, um, again, you're looking at, uh, hundred foot tall trees, and the flame links were probably one and a half times that much. So, it was an incredible sight to see fires, uh, groves of trees burning like that with huge flame links and a tremendous amount of heat coming through.
BILL BLAKEMORE
[04:59:27:23] What's a flame link?
MAT FRATUS
Uh, that would be the, the length of the flame from the base of its origin up to the tip of the flame.
BILL BLAKEMORE
Oh right, extraordinary.
[OFF CAMERA COMMENTS]
BILL BLAKEMORE
[04;59;43;23] Keep talking about what we're looking at here.
MAT FRATUS
OK, um, one f the problems that we had in the fire was once we got into heavily populated areas like this, uh, the trees burning was one thing, but as we started burning the houses, the, the synthetics, the chairs, the wall coverings, and so forth, they actually burn with about twice the intensity of the natural vegetation. [05:00:05:12] So these became a fuel model all by themselves, so several hundred homes burning at a, at one single time, uh, represented a tremendous amount of heat that just proliferated the fire.
BILL BLAKEMORE
Wow.
MAN
That's great.
[BREAK IN AUDIO]
MAT FRATUS
[05;00;19;04] [AUDIO PICKS UP MID SENTENCE] .big when we started, and now it's, you know, it's this, this was probably-
BILL BLAKEMORE
Fascinating.
MAT FRATUS
You know, this was a multi-story house, so you could have been looking, um, eighteen hundred to two thousand square feet, and you wouldn't ever think it just by looking at this area here, it doesn't look that big.
BILL BLAKEMORE
[05;00;34;22] Wow. Wow. Did you always know you wanted to be a fireman?
MAT FRATUS
Um, you know, I can't say that I did.
BILL BLAKEMORE
We, we met each other when we were paired on a couple of hurricane stories in 2004, and found a mutual interest in nature stories, but global warming especially, and then Clayton came up with this great idea last spring.
