Summary

Wildfire is not an intractable climate-only problem in Bill Clerico’s account; it is an adaptation and infrastructure problem with addressable causes. Climate change lengthens hotter, drier seasons, but forests are roughly three times denser after a century of “maximum suppression.” Meanwhile, 98% of climate capital goes to mitigation and just 2% to resilience and adaptation—a split he sees finally shifting.
The highest-leverage prevention is more prescribed fire and mechanical thinning, but regulation and local risk aversion make both painfully slow. Clerico’s own 170-acre timber treatment took three years and six biologist visits; Sarah Guo cited average environmental reviews of 4.7 years for simple projects and 7.5 for complex ones. Florida burns 2–3 million prescribed acres annually, while California targeted only 100,000: “The forests are going to burn…we can do it on our terms or they can do it on their terms.”
Housing growth has converted wildfire into an urban balance-sheet problem. Homes in the wildland-urban interface have increased 46% since 1980, yet Paradise largely rejected tougher codes while rebuilding after the 2018 Camp Fire. Once flames cross a community’s perimeter, Clerico says the event becomes an “urban conflagration,” spreading house to house and becoming vastly harder to stop.
Utility mitigation offers unusually concentrated loss reduction: utilities cause about 11% of ignitions but 50% of damage. Vegetation management, sensitive breakers, public-safety power shutoffs and undergrounding can help, though undergrounding costs $3–4 million per mile. The constraint is not utilities’ aversion to CapEx—they can mark spending up roughly 15%—but regulators and ratepayer advocates resisting already-high bills.
California’s insurance retreat follows regulated prices that stopped reflecting risk, not simply insurer unwillingness. Until recently, admitted-market rates could not include reinsurance costs—which doubled or tripled over five to ten years—or forward-looking catastrophe models, relying instead on 30 years of history. Clerico’s diagnosis: the state “choked rates so low that…we broke the system,” pushing policies toward the FAIR Plan and non-admitted carriers such as Stand, one of his companies.
Drones could become a meaningful wildfire-response category over the next five to ten years as payload, swarming and flight regulations improve. Clerico expects pre-positioned systems to attack camera- or satellite-detected ignitions before they spread, or carry suppressant over blocked roads for structure defense. The low-tech version already exists: he keeps 20 gallons of Barricade gel and argues WUI homeowners should consider their own applicator, pump and water supply.
The enduring bottleneck is political memory and incentive design, not a shortage of isolated technical fixes. Elad Gil proposes a “Smokey Bear 2.0” that advocates for healthy fire, while Clerico focuses on changing public attitudes toward prescribed burns, faster permits for safer rebuilding and insurance pricing that rewards hardening. Elad also frames wildfire as a neglected national-security exposure, asking what would happen if 30 fires threatened military bases or nuclear power plants and overwhelmed the system.

Deep dive

1. Climate amplifies fires, but suppression built the fuel load

Clerico rejects the binary: climate change is lengthening hot, dry fire seasons, while the recent “crescendo” comes more from forest management and “the way we’ve constructed our electrical grid.” His capital-allocation marker is 98% of climate funding going to CO2 mitigation versus 2% to resilience and adaptation—a pendulum he thinks is now swinging rapidly.
Beginning in the 1930s, the Forest Service pursued “maximum suppression,” including a 10:00 a.m. policy requiring reported fires to be extinguished by the next morning. That interrupted frequent, low-severity burning and left forests “denser and denser and denser and denser”—at least three times denser than around the turn of the century, before hotter, drier conditions are added.
Reversing that accumulation means prescribed burns under safer spring conditions and mechanical thinning. Both are unpopular: residents resist smoke, while a burn boss faces asymmetric career risk if a fire escapes. Florida’s established culture supports 2–3 million prescribed acres annually; California targeted 100,000, likely missed it, and hopes eventually to reach one million acres over a decade.
Clerico’s 170 acres of Douglas fir and redwood took three years to treat, including six visits by a contract biologist calling for northern spotted owls. Sarah cited reviews averaging 4.7 years for simple projects and 7.5 for complex ones; the Forest Service reportedly spends 40% of its budget, about $250 million annually, on planning. She also pointed to the bipartisan Fix Our Forests Act as a permitting-reform attempt.

2. Development turned forest fires into urban conflagrations

Housing units in the wildland-urban interface, or WUI, have grown about 46% since 1980 as communities expanded into high-risk terrain. Clerico argues that this makes equivalent acreage burned far more destructive than 20 years ago. Paradise’s choice to rebuild largely under existing codes after the 2018 Camp Fire captures the political problem: safer requirements were rejected as too costly and restrictive.
Clerico’s preferred design is layered defense. Perimeter homes need aggressive vegetation clearance, modern roofs and materials, tempered glass, sprinklers, water and driveways large enough for engines to enter and turn. “Zone 0”—the first five feet around a structure—should contain no flammable material; paired with a good water source, he says, a homeowner is “in the top quartile.”
Once fire penetrates the perimeter, it becomes an “urban conflagration”: houses ignite other houses, with dynamics resembling historic Chicago or San Francisco fires. During the Palisades evacuation, abandoned cars blocked engines that were shifting from initial attack to structure defense. Clerico says staffing is not his area of expertise, but doubts that 20% more engines would have changed the outcome; he views the cited $17.5 million departmental cut as small relative to the broader budget.
The water problem was primarily an acute pressure failure, not evidence that California simply lacked reservoirs. Three one-million-gallon tanks lost pressure as hundreds of burned homes left service lines flowing; 500 connections at 20–30 gallons per minute create enormous demand. Clerico pushes back on broader reservoir claims as “a bit tenuous,” suggesting modular systems that can isolate neighborhoods and preserve pressure.

3. Utility risk is concentrated, but regulated economics delay upgrades

Utilities cause roughly 11% of ignitions yet about 50% of damage because the same winds that create extreme fire behavior also topple lines and break equipment. Clerico argues that sharply reducing utility ignitions could therefore reduce roughly half the damage before suppression capacity is tested.
Available measures include trimming vegetation, more sensitive breakers and PSPS or ESPS shutoffs before red-flag events. Overstory, one of Clerico’s fund’s investments, helps utilities prioritize tree work for maximum effect. Undergrounding is another option, but at $3–4 million per mile it feeds directly into higher electric rates; shutoffs are cheaper but unpopular with customers.
Lightning is probably about one-third of ignitions and often creates large, remote-acreage fires, though Clerico notes startups exploring ways to de-energize thunderclouds. Arson or other human causes represent at least 10%; he suspects the problem is growing based on conversations with fire chiefs, while acknowledging, “I don’t have hard data about this.”
Sarah cited estimates that California is $100 billion behind on undergrounding and other mitigation, along with the Camp Fire’s failure of a 97-year-old electrical component. Clerico’s counterintuitive defense is that regulated utilities “would die to spend that money”: they can earn about a 15% markup on CapEx, but regulators constrain rates. He separately estimates that the broader investment need is in the hundreds of billions. The hosts note California bills are already high; Clerico concedes waste, including expensive biomass mandates, while still arguing more spending is required.

4. Insurance repricing and drone response are emerging markets

California admitted-market insurers historically could neither pass through reinsurance costs nor use forward-looking risk models. Reinsurance costs at least doubled, perhaps tripled, over five to ten years, while pricing still relied on 30 years of historical experience. Insurers compared permitted premiums with changing risk and concluded: “This is not a business. You know, we can’t do this.”
The FAIR Plan compounds exposure by assessing insurers according to state market share, so writing another policy adds residual-plan risk. After widespread non-renewals, the commissioner began allowing reinsurance costs and forward models within the prior three to six months, though restrictions remain. Clerico says California “choked rates so low that…we broke the system”; Stand, one of his companies, instead writes unregulated, non-admitted policies.
Drone response was previously constrained by payload capacity and beyond-visual-line-of-sight rules, but Clerico says both technology and regulation have recently changed. Over five to ten years, he expects pre-positioned drones to attack camera- or satellite-detected ignitions rapidly, then swarm for structure defense—avoiding blocked roads and carrying their own suppressant and other supplies.
The simpler version is already available. Clerico keeps about 20 gallons of Barricade gel at his Mendocino property and would spray the structure himself; he sees “no reason” similarly exposed homeowners should not own suppressant, an applicator and a fire pump. Some large insurers already dispatch private structure-defense services, although the Los Angeles fire advanced too quickly for many teams to arrive.

5. Recovery depends on incentives—and sustained political memory

Clerico wants the Palisades rebuilt to a higher safety standard despite many owners being uninsured or underinsured and facing substantial costs. Elad’s pushback is that nearly every failure described already reflects regulatory and policy overburdening. Clerico’s preferred reconciliation is market-led: let insurers condition coverage on hardening, while government invests in shared infrastructure rather than simply adding mandates.
Cities should create major fuel-management projects around exposed communities; Clerico cites work in Lake Tahoe that many people think helped protect South Lake Tahoe during the Caldor Fire. For individual rebuilding, he suggests a voluntary fast track: a home meeting higher standards might receive approval in two weeks instead of six months, aligning speed with safety without universally tightening the code.
Elad proposes a “Smokey Bear 2.0”—an advocate for healthy, controlled fire rather than universal suppression. Clerico agrees that the public needs to understand prescribed fire as safe when properly managed and essential. Opposition crosses party lines: he recalls an Oregon Republican sheriff arresting a Forest Service employee over a prescribed burn. Elad’s framing is categorical: “The forests are going to burn. We can do it on our terms or they can do it on their terms.”
For the active incident, Clerico says three forces generally stop major wildfires: changing weather, the ocean or massive aircraft retardant drops, which cannot be used in neighborhoods because they would be too destructive and disruptive. Longer term, tighter building restrictions and more surveillance could improve response and expose arson.
Elad separately flags a neglected national-security risk: fires near military bases or nuclear power plants, and the possibility of 30 simultaneous fires overwhelming the system.
