It follows the people making those choices now. It treats climate anxiety as a reasonable response to real conditions. It won't tell you what to do, but it shows the tradeoffs clearly. [Read on the website]() ## Issue 20 — Cascading Effects How climate reshapes business, insurance, and infrastructure affecting everyday lives ### The Data Wars - [The Climate Data That Disappeared Without Anyone Changing the Rules]() — By [Ivy Marlowe]() · Published 2026-02-16 · Format: The Data Wars In November 2025, climate risk information vanished from California property listings on Zillow. Wildfire exposure, flood projections, heat risk, air quality—gone. The data remained public, still accessible through government databases. Where homebuyers actually search, though, it disappeared. No new regulations required this. No rules changed. Someone decided you shouldn't see it there anymore. And when that happened, someone else started building a workaround to restore what was always public in the first place. ### What Disappeared - [When Zillow Hid the Flood Maps]() — Published 2026-02-16 Until November 14, 2025, every Zillow listing showed property-specific climate scores: flood probability, wildfire risk, wind exposure, heat projections, air quality ratings. Fifteen and thirty years out. Then California's largest MLS complained that flood models showed 50% risk in neighborhoods that hadn't flooded in decades. Zillow pulled everything. ### Measuring Risk Pull up your flood risk on three different platforms. You might get three wildly different answers. One says you're clear. Another puts you in a high-risk zone. The third suggests your insurance company has been underpricing your policy for years, and they're about to correct that mistake. The divergence exists because these platforms measure fundamentally different things using different data sources and timeframes. Some look backward at what flooded before. Others project forward using climate models that disagree with each other. The confusion matters because homeowners trying to make real decisions about real money get contradictory information, and insurance premiums can triple overnight when carriers switch which model they trust. - **First Street Bets on Tomorrow** — [Source]() — Published 2026-02-16 Tag: Forward Projections First Street runs CMIP6 climate projections forward thirty years, layering sea level rise and rainfall pattern shifts onto property-level flood models. Each address gets a Flood Factor score based on cumulative future risk, not what happened last decade. - **FEMA Maps What Already Happened** — [Source]() — Published 2026-02-16 Tag: Historical Data FEMA flood maps use historical flow data, period. No climate adjustments, no forward modeling. Some maps date to the 1970s because Congress won't fund adequate updates. They're regulatory snapshots for insurance pricing, frozen at whatever conditions existed when surveyors last showed up. - **Six Million Properties FEMA Missed** — [Source]() — Published 2026-02-16 Tag: Risk Gap First Street counts 14.6 million at-risk properties nationwide. FEMA counts 8.7 million. In Kentucky's Appalachian counties alone, that's 22,086 properties versus 6,562. The gap means millions of homeowners are underestimating their exposure because the official maps say they're fine. - **Proprietary Models Set Your Premium** — [Source]() — Published 2026-02-16 Tag: Insurance Pricing Insurance companies run their own catastrophe models using IPCC scenarios but rarely publish methodology details. Most do "exploratory" analysis of possible futures without stress testing worst cases. Premium calculations vary wildly depending on whether carriers use FEMA's outdated maps or fully risk-based assessments. - **Inland States Show Biggest Disagreements** — [Source]() — Published 2026-02-16 Tag: Geographic Divergence Platform divergence spikes in places FEMA mapped poorly. First Street found four times more at-risk properties in Utah, Wyoming, and Montana than FEMA did. Cleveland County, Arkansas: FEMA identified twelve properties at risk. First Street estimated 1,500. - **Each Platform Proves Itself Differently** — [Source]() — Published 2026-02-16 Tag: Validation Methods First Street validates against historical flood reports and FEMA claims data. Insurance models validate using state disaster records and premium collections. FEMA validates against regulatory compliance standards. Different validation methods measuring different phenomena. Accuracy comparisons become nearly impossible. ### Further Reading - **Flood-Prone Homes Overvalued by Up to $237 Billion** — [Source]() — Published 2026-02-16 Nature Climate Change study finds massive mispricing where disclosure laws are weakest and climate concern lowest. - **Floodplain Properties Worth $44 Billion Less Than Market Prices** — [Source]() — Published 2026-02-16 Stanford research: buyers discount flood risk at 2% when full insurance costs justify 4.7-10.6%.

They ask if the roof leaks, whether the foundation has cracks. What they don't ask: whether wildfire smoke deposited toxic metals in your air ducts, whether your neighborhood traps heat seventeen degrees hotter than the suburbs, whether the land beneath your house is sinking. The gap between what buyers learn and what risks they face keeps widening. Some omissions exist because standards don't exist yet. California just introduced the nation's first smoke contamination testing this month. Others persist because the information is contested, outdated, or simply not required by law. - **No Standards for Smoke-Damaged Homes** — [Source]() — Published 2026-02-16 Tag: Wildfire Contamination California passed the nation's first testing requirements this month. Before that? Nothing. Homes miles from actual fires can have lead dust from burned materials settled in air ducts. Nobody was required to test for it or clean it. - **FEMA Maps Look Backward, Not Forward** — [Source]() — Published 2026-02-16 Tag: Flood Projections Two-thirds of FEMA maps are over five years old. They show historical flooding, not future risk. Climate-driven rainfall patterns and sea level rise don't factor in. Property owners can hire engineers to shrink their mapped flood zone by half. - **Seventeen Degrees Hotter Across Town** — [Source]() — Published 2026-02-16 Tag: Urban Heat Washington, DC's inner city runs seventeen degrees hotter than surrounding areas. Low-income families live in dangerously hot homes at three times the rate of wealthy households. No disclosure exists for neighborhood heat risk or whether buildings trap heat. - **Groundwater Depletion Sinks Property Values** — [Source]() — Published 2026-02-16 Tag: Land Subsidence Central Valley homes lost between $6,689 and $16,165 in value as groundwater pumping causes land to sink. Texas requires disclosure only if sellers already know they're in a subsidence district. No duty to investigate means most don't. - **Five Hundred Feet From Uninsurable** — [Source]() — Published 2026-02-16 Tag: Coastal Insurance Carriers refuse coverage for homes within five hundred feet of water or documented erosion zones. Some use climate models to predict which properties might be underwater within a mortgage term. A new category of coastal real estate nobody will insure. - **Aquifer Models Disagree on Depletion Timeline** — [Source]() — Published 2026-02-16 Tag: Water Supply Wickenburg, Arizona's water district manager watches his aquifer drop steadily since 2018. People ask if the town will run out of water. "I tell them I don't know, and that's the honest answer. The models don't agree." ## Other sections in Issue 20 - [Human Stories]() - [Emerging Science]() - [Future Tense]() - [Climate Past]() - [The Lab]() ## More - [Publication guide]() - [Issue archive]()
