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 31 — Cascading Effects How climate reshapes business, insurance, and infrastructure affecting everyday lives ### Showing the Math - [Louisville Rebuilt Harder. Colorado's New Insurance Law May Not Know It.]() — By [Maya Jiménez]() · Published 2026-05-06 · Format: Showing the Math The houses on Via Appia Drive in Louisville, Colorado, have Class A metal roofs, fiber cement siding, ember-resistant vents screened to one-eighth of an inch. They replaced homes that a 100-mph grassfire took on December 30, 2021. The families who rebuilt them were 74 percent underinsured and did it anyway. On July 1, Colorado becomes the first state to require insurers to show homeowners the wildfire risk score driving their premiums. Louisville's rebuilders will finally see the number. The number may not see what they built. ### The Pullback - [Zillow Pulled Climate Risk Scores From Listings. Connecticut Published Them for Free.]() — Published 2026-05-06 In September 2024, Zillow added First Street climate risk scores to every for-sale listing in the country. The company's chief economist praised the move, saying "healthy markets are ones where buyers and sellers have access to all relevant data." Fourteen months later, after sustained complaints from the real estate industry that the scores were suppressing sales, Zillow stripped them from its platform entirely. ### The Reform Map Your insurance company knows exactly how risky your property is. Until this year, it had no obligation to share that assessment with you. You could be dropped, repriced, or quietly non-renewed based on a catastrophe model you've never seen and can't challenge. Now 18 states are pushing legislation to crack open that black box. The bills vary. Some demand model disclosure. Some mandate premium credits for mitigation. Hawaii's were written with Lahaina survivors in the room. But they share a core premise: the growing distance between what insurers know about your home and what you're allowed to know is no longer a market quirk. It's a policy failure. Here's where the most significant efforts stand. - **Eighteen States Want Insurers to Show Their Math** — [Source]() — Published 2026-05-06 Tag: The Wave At least 18 states introduced insurance reform bills in 2026, most borrowing from Colorado's playbook. The shared logic: if insurers use catastrophe models to cancel your policy, you should see the score and have a shot at improving it. Seven states copied Colorado's framework nearly verbatim. The push is bipartisan, driven less by ideology than by constituents calling their legislators after getting dropped. - **Colorado Wrote the Bill Everyone Else Copied** — [Source]() — Published 2026-05-06 Tag: The Template HB25-1182 took effect January 2026. Insurers must disclose wildfire risk models and reduce premiums when homeowners harden their properties. Companies without a property-specific model must offer manual mitigation discounts anyway. It's the first law that treats the information gap between insurer and homeowner as a regulatory problem worth fixing. Seven states have introduced near-copies. - **Washington's Senate Voted 48–1 for Transparency** — [Source]() — Published 2026-05-06 Tag: Near Unanimous SB 5928 requires insurers to disclose wildfire risk scores, explain the factors behind them, and update scores within 30 days of completed mitigation work. A companion bill funds voluntary mitigation grants. The 48–1 Senate vote suggests something unusual in climate-adjacent legislation: almost nobody wanted to be on record defending the information asymmetry. - **Lahaina Survivors Shaped Hawaii's Reform Bills Directly** — [Source]() — Published 2026-05-06 Tag: Survivor Driven SB 2947 and SB 802 emerged from testimony by Maui wildfire survivors who learned they were underinsured only after losing everything. The bills require mitigation premium credits, mandate rate reviews, and prohibit insurer retaliation against policyholders who file complaints. The retaliation provision is distinctive. It acknowledges what other states' bills don't: that filing a complaint can itself become a risk factor. - **California Goes Further Than Transparency Alone Can** — [Source]() — Published 2026-05-06 Tag: FAIR Overhaul Nine consumer protection laws took effect January 1, including wildfire safety grants for fire-safe roofs. Now AB 1680, the Make It FAIR Act, targets the FAIR Plan itself after documented failures handling LA wildfire claims. California's approach goes well beyond the Colorado model. It's trying to fix the insurer of last resort, not just the information flow. - **New York Wants Zip-Code-Level Cancellation Data Published** — [Source]() — Published 2026-05-06 Tag: Data Mandate S.8583 would force insurers to submit zip-code-level data on nonrenewals, cancellations, claim rates, and premiums. That granularity could expose "bluelining," the quiet withdrawal of coverage from entire neighborhoods. The bill adds Colorado-style mitigation credits too. Still in committee, but the data provision alone would be unprecedented if it passes. ### Further Reading - **As Climate Crisis Upended Homeowners Insurance, the Industry Resisted Regulation** — [Source]() — Published 2026-05-06 Capital & Main obtained documents showing how industry groups lobbied to gut climate disclosure standards between 2022 and 2024. Essential reading for understanding why the data you'd need to make informed decisions about your home still doesn't reach you. - **Colorado Homeowners Will See Their Wildfire Risk Scores Starting July 1. Here's What That Means.** — [Source]() — Published 2026-05-06 Colorado's HB25-1182 is the closest thing to a working model for what mandated risk transparency looks like in practice. This piece walks through what insurers will actually have to hand over to policyholders and when. - **Risk and Resilience: How States Are Approaching Insurance and Climate Risk in 2026** — [Source]() — Published 2026-05-06 PreventionWeb and NCSL map the eighteen states now writing insurance transparency into law, many borrowing from Colorado's playbook. Useful for seeing how fast the legislative landscape shifted once one state proved the model could survive industry opposition. - **Major U.S. Insurers Make Progress on Climate Disclosures, but Significant Gaps Remain** — [Source]() — Published 2026-05-06 Ceres found that 85% of major U.S. insurers now claim to disclose climate risk. Only 29% share quantitative targets or loss data. The gap between those two numbers is the transparency problem in miniature: compliance without substance. - **The Growing Void in the U.S. Homeowners Insurance Market** — [Source]() — Published 2026-05-06 This peer-reviewed Nature study makes the structural argument: the homeowners insurance crisis can't be addressed without risk data transparency as a foundation. Worth reading alongside the Ceres report above to see how far current disclosure falls short of what the researchers say is needed. - **Corporate Climate Risk Disclosure Landscape in 2026** — [Source]() — Published 2026-05-06 With the SEC disclosure rule effectively dead and California's climate laws tied up in court, the federal framework for climate risk transparency has collapsed. This piece explains the regulatory vacuum that pushed the entire fight down to state insurance commissioners and legislatures. ### What You Can Find You've probably done the thing. Sat down one evening, typed your address into three different websites, and tried to figure out what climate change actually means for your house. Six browser tabs. Three contradicting each other. None answering the question you came with. The information landscape for property-level climate risk is genuinely fragmented, and the fragmentation isn't random. Government maps miss entire categories of flooding. The most comprehensive insurance dataset ever collected won't be public until 2027, and even then, the property-level detail stays locked behind confidentiality provisions. Private platforms fill gaps but can't agree with each other. One state has built a free risk tool for residents. Forty-nine haven't. We mapped what homeowners can actually access right now, what's coming, and where the blind spots sit. - **The Maps Miss the Rain That Floods You** — [Source]() — Published 2026-05-06 Tag: Flood Maps FEMA flood maps track rivers and coasts. They largely ignore pluvial flooding, where rainfall simply overwhelms drainage. Nearly 10 million high-risk properties sit outside mapped zones. During Harvey, 70% of flooded Houston homes were in areas the maps considered safe. The fastest-growing flood category is the one nobody's required to show you. - **The Biggest Insurance Data Haul Isn't Yours** — [Source]() — Published 2026-05-06 Tag: Insurance Data The NAIC's 2026 nationwide data call pulls ZIP-level homeowners insurance data from 2018 through 2025: premiums, cancellations, losses by peril. The public report lands early 2027. But individual property risk scores and insurer underwriting models stay confidential. Regulators will see the picture. You'll get a summary. - **Private Risk Scores Exist but Can't Agree** — [Source]() — Published 2026-05-06 Tag: Private Platforms First Street and ClimateCheck offer forward-looking, property-level climate risk scores that FEMA doesn't. They're genuinely useful. They also disagree with each other more than half the time on which properties face extreme risk, according to Bloomberg's analysis. No regulated standard governs the models. No meaningful appeals process exists if a score tanks your home's value. - **Connecticut Built a Tool. No One Followed.** — [Source]() — Published 2026-05-06 Tag: State Experiment Connecticut became the first state to offer residents free, address-level climate risk assessments covering floods, fire, wind, and heat. Starting July 2026, sellers must disclose flood history at closing. Real estate agents worry the scores will scare off buyers, which tells you something about what the scores show. No other state has replicated the tool. - **Your Lender's Risk Model Doesn't Face You** — [Source]() — Published 2026-05-06 Tag: Lender Asymmetry Mortgage lenders increasingly run proprietary climate risk models on properties before approving loans. Nothing requires them to share those scores with borrowers. Research from Duke shows local lenders quietly offload climate-risky mortgages to Fannie Mae and Freddie Mac at prices that ignore flood exposure. The lender prices the risk, acts on it, and keeps the analysis to itself. - **No Federal Law Makes Sellers Tell You** — [Source]() — Published 2026-05-06 Tag: Disclosure Gaps There is no federal requirement for sellers to disclose flood risk or damage history. Over half of states lack meaningful disclosure legislation. Where disclosure forms do exist, they reference the same incomplete FEMA maps that miss pluvial flooding entirely. Only eleven states require landlords to tell renters anything at all. The gap compounds at every level. ## Other sections in Issue 31 - [Human Stories]() - [Emerging Science]() - [Future Tense]() - [Climate Past]() - [The Lab]() ## More - [Publication guide]() - [Issue archive]()
