Morton "Mort" Ledger didn't choose his nickname. It chose him sometime during his third year verifying hurricane damage claims for a class-action lawsuit in Louisiana. "Mort" because he counts losses, "Ledger" because that's his actual surname, and the whole thing so perfectly suited to his profession that clients started requesting him by name. For fifteen years, he's worked as a forensic accountant specializing in disaster cost verification—the person lawyers hire when they need to prove, down to the dollar, exactly how much a flood or wildfire or tornado actually cost.
His work depended entirely on one thing: NOAA's U.S. Billion-Dollar Weather and Climate Disasters database, which tracked every major disaster since 1980 with methodical precision.
That database stopped updating in May 2025.1
We meet at a coffee shop in Austin, where Mort has just finished testifying in a case about the 2024 Texas freeze. He's drinking an iced coffee despite it being February, and he's brought a laptop covered in stickers from various disaster sites—a morbid travel log. When I ask if the stickers are ironic, he looks genuinely confused. "No, I was actually there for all of these. Why would that be ironic?"
So your entire job is counting disaster costs?
Mort: That's reductive but yeah, essentially. When a city sues the power company over grid failure, or when a state challenges federal disaster declarations, or when insurance companies dispute damage claims, someone needs to verify the numbers. That's me. I reconstruct costs from the ground up. Property damage, business interruption, infrastructure repair, agricultural losses, everything. Then I compare it against historical baselines to establish whether this disaster was anomalous or consistent with patterns.
He pauses.
Or I used to do that. Past tense increasingly applies.
Because NOAA stopped tracking?
Mort: Because my reference standard disappeared. Imagine you're a chemist and someone removes the kilogram prototype from Paris. You can still weigh things, but against what?
NOAA's database was my kilogram. It was the official record—peer-reviewed, inflation-adjusted, methodologically consistent across 45 years. When I testified, I'd say "according to NOAA" and that ended the argument. It was the shared reality we all agreed to reference.
Now Climate Central is tracking disasters, which is great, but they're a nonprofit, not a federal agency.2 Defense attorneys are already challenging my reports: "Why should we accept Climate Central's methodology? Who peer-reviewed this? What's their funding source?"
These are bad-faith arguments, but they work. I'm watching my professional foundation crumble in real-time.
What does a case look like without that foundation?
Mort: Chaos. Beautiful, lucrative chaos.
I'm currently working three cases about the 2025 Los Angeles fires. $61 billion in damages, supposedly.3 But "supposedly" is doing heavy lifting now. One plaintiff's attorney wants me to verify that figure. The defense attorney wants me to prove it's inflated. Both are paying me, which feels ethically uncomfortable but technically fine since I'm just reporting what I find.
Except what I'm finding is that nobody agrees on anything anymore. Climate Central says $61 billion. Insurance industry estimates say $48 billion. The state of California's preliminary assessment says $71 billion.
These aren't rounding errors. These are different disasters depending on who's counting.
How do you decide which number is correct?
Mort: laughs I don't. I present all three, explain the methodological differences, and let the jury decide. Which is insane. We're asking twelve random people to adjudicate between competing disaster accounting frameworks. It's like holding a trial where we can't agree if the defendant was even in the room.
The thing is, NOAA's methodology wasn't perfect. They counted direct costs—physical damage, crop losses, infrastructure repair. They explicitly didn't count indirect costs like business interruption, supply chain disruption, healthcare costs from heat-related illness, ecosystem damage. The UN now estimates total disaster costs at $2.3 trillion annually when you include cascading effects—ten times the official direct loss figures.4
So maybe NOAA was always undercounting. But at least it was consistent undercounting. We all knew what we were measuring.
You sound almost nostalgic for systematic undercounting.
Mort: I'm nostalgic for shared reality.
Look, I know how this sounds. Forensic accountant mourns the death of a federal database, world's smallest violin, et cetera. But here's what keeps me up at night: if we stop officially counting disasters, do they stop officially existing?
I'm working on a case right now where a small town in Oklahoma is suing for federal disaster relief after a tornado outbreak last spring. FEMA—which might not exist by the end of this year, whole other nightmare—is disputing whether the damage threshold was met.5 The town says $120 million in damages. FEMA's preliminary assessment says $89 million.
In the old world, we'd check NOAA's database, see if it qualified as a billion-dollar disaster or not, use that as a baseline for similar events. Now? I'm literally going house to house with the town's attorney, photographing damage, checking property records, interviewing residents about what they lost.
It's like I'm inventing disaster accounting from scratch, which would be exciting if it weren't so terrifying.
Terrifying how?
Mort: Because I'm one guy with a spreadsheet. What if I miss something? What if I count something twice? What if my methodology is challenged and I can't point to NOAA's 45-year track record as justification?
I used to be a translator, taking complex data and making it legally legible. Now I'm the data source itself, and that's way too much responsibility.
Plus there's the darker question: How many disasters are we missing entirely? NOAA tracked events that crossed the billion-dollar threshold. Climate Central is trying to maintain that standard. But what about the $800 million disaster? The $500 million disaster?
We're in this weird epistemological crisis where disasters might be happening but not being officially recorded because the recording infrastructure collapsed.
Is anyone trying to rebuild that infrastructure?
Mort: shrugs Climate Central is doing heroic work with limited resources. Some academics are trying to create alternative tracking systems. But here's the problem: NOAA had authority. When they said "this was a billion-dollar disaster," that became legal fact. Climate Central can say the same thing, and they might be using identical methodology, but they don't have federal authority behind them.
It's like the difference between a police report and a really detailed blog post about a crime. Both might contain the same information, but only one is admissible in court without challenge.
So what do you do?
Mort: I adapt. That's the only option.
I'm developing my own verification protocols, building relationships with state emergency management offices, creating disaster cost databases for specific regions. It's more work, it's less authoritative, but it's what the moment requires.
And honestly? Business is booming. When shared reality breaks down, you need more forensic accountants, not fewer. Every disputed disaster declaration, every insurance fight, every lawsuit about inadequate preparation—they all need someone to count the costs. I'm hiring two associates this year.
The irony is that as disasters get worse and more frequent, and as our ability to systematically track them degrades, my particular skill set becomes more valuable. I'm professionally thriving during an epistemological collapse.
It feels gross but also... pauses ...I don't know. I'm just trying to do the work honestly.
What happens in five years if this continues?
Mort: We'll have regional disaster accounting instead of national tracking. Texas will count disasters one way, California another way, Florida a third way. We'll lose the ability to compare across time and space, to say "this disaster was worse than that disaster" with any confidence. Historical analysis becomes impossible because the methodology keeps changing.
And litigation becomes even more of a nightmare. Right now I can still reference NOAA's historical data for context—"here's what similar hurricanes cost in the past." But that data stops in May 2025. Every year forward, we have less historical comparison, less context, less shared understanding.
Eventually we'll reach a point where we can't even agree on basic questions like "how many billion-dollar disasters happened this year?" We'll have multiple competing counts, all defensible, none authoritative. And when you can't agree on what happened, you definitely can't agree on what to do about it.
He finishes his coffee and starts closing his laptop, then pauses.
The really dark joke? My job security has never been better. As long as people are arguing about what disasters cost, I'll have work.
I just wish the work wasn't necessary because we'd maintained the infrastructure to prevent the arguments in the first place.
But that's not the world we're in anymore.
