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 24 — Cascading Effects How climate reshapes business, insurance, and infrastructure affecting everyday lives ### Beyond the Fire Line - [SYSTEMS: Insurance Left Urban LA. The Risk Models Can't Explain Why.]() — By [Maya Jiménez]() · Published 2026-03-18 · Format: Beyond the Fire Line The most combustible thing on the block is somebody's wooden fence. Flat lots, stucco walls, concrete driveways browning under water restrictions. Miles from any canyon where Santa Ana winds turn lethal. In neighborhoods across southern LA County where Black and Latino families built homeownership against redlining and predatory lending, the non-renewal letters started arriving anyway. Wildfire risk, the letters said. The families looked at their blocks and couldn't make it make sense. ### The Premium Question - [The 2025 Hurricane Season Was Quiet. Your Insurance Bill Probably Won't Notice.]() — Published 2026-03-18 Your homeowners premium has likely nearly doubled since 2020. The national average now hovers around $2,400, up from roughly $1,300 five years ago. A calm 2025 hurricane season slowed the bleeding. AM Best upgraded its industry outlook to "Stable." Florida's insurer of last resort approved its first rate cut since 2015. ### Who Measures Risk Say you're buying a house this spring. You want to know if it floods. Reasonable question. The answer you get will depend on which website you're browsing, which state you're buying in, and whether the most accurate risk model happened to survive on the platform you checked. There is no unified climate risk picture for American homebuyers. What exists is five overlapping, sometimes contradictory layers of information, each with its own blind spots, each controlled by different institutions with different incentives. Some of the best data is proprietary. Some of it just got deleted. Some was never collected. Here's what each layer actually tells you, and where it goes silent. - **FEMA's Maps Don't Know It Rains** — [Source]() — Published 2026-03-18 Tag: Federal Maps The baseline federal flood maps, which determine National Flood Insurance Program requirements, ignore pluvial flooding entirely. Rain that overwhelms storm drains and pools in low spots simply doesn't register. Between 58% and 75% of maps are outdated. During Harvey, roughly 70% of flooded Houston homes were outside designated high-risk zones. Twenty-six million Americans live in floodplains the maps pretend aren't there. - **First Street's Data Now Depends on Where You Browse** — [Source]() — Published 2026-03-18 Tag: Private Models First Street Foundation models flood, fire, wind, heat, and air quality at the property level, estimating 1.7 times more at-risk properties than FEMA identifies. Zillow pulled the scores in November 2025. They still appear on Redfin, Homes.com, and Realtor.com. Whether you see the risk depends on which tab you have open. - **The Real Risk Models Are Behind a Paywall** — [Source]() — Published 2026-03-18 Tag: Industry Pricing Catastrophe models from RMS/Moody's and Verisk are what insurers actually use to price your policy or cancel it. They're licensed exclusively to the industry. Different models applied to the same property can diverge by 100% to 250%. You'll see the output only as a premium increase or a nonrenewal letter. - **One State Built Something. Most Haven't Bothered.** — [Source]() — Published 2026-03-18 Tag: State Tools Connecticut launched a free, First Street-powered climate risk mapping tool in fall 2025, giving residents property-level reports on flood, fire, and heat exposure. It's the first of its kind. Twenty-three states still require no flood history disclosure at all. Only California and Oregon mandate fire risk disclosure to buyers. - **When the Models Disagree, You're on Your Own** — [Source]() — Published 2026-03-18 Tag: The Gap No single source captures the full picture, and where they overlap, they often contradict each other. In the Uerkwitz lawsuit, filed October 2025, sellers alleged First Street's "extreme flood risk" designation cost them $100,000 on a property they insist doesn't flood. Meanwhile, only 3.3% of U.S. homes carry flood insurance. The models fight. Buyers guess. ### Further Reading - **Even Low-Risk Homes Are Caught Up in California's Climate Insurance Crisis** — [Source]() — Published 2026-03-18 Insurance Journal reports that 14% of California's insurer-of-last-resort policies now cover homes in low-risk urban neighborhoods, far from any wildfire zone. The piece tracks how insurer retreat is spreading well beyond the areas most people associate with climate risk, pulling ordinary homeowners into a crisis they assumed belonged to someone else. - **As Climate Crisis Upended Homeowners Insurance, the Industry Resisted Regulation** — [Source]() — Published 2026-03-18 Capital & Main's investigation documents how insurance trade groups spent four years lobbying against international climate risk guidance, even as those same companies were cancelling policies and raising premiums on the basis of climate risk. Essential reading for understanding the gap between what insurers say publicly about climate and what they fight for behind closed doors. - **2025 Saw Relatively Fewer Natural Disasters. Will You Get a Break on Home Insurance?** — [Source]() — Published 2026-03-18 NPR walks through the national premium landscape with unusual clarity, explaining why a relatively calm disaster year hasn't translated into lower bills. The short answer involves reinsurance costs, replacement value inflation, and an industry that prices for the future it models, not the year it just had. The best current overview of where rates stand and why. - **Choosing the Right Home Is Tough. Climate Change Is Making It Harder** — [Source]() — Published 2026-03-18 Inside Climate News covers First Street Foundation's projection that climate risk will erase $1.47 trillion in U.S. property value, then zooms in on what that means for anyone trying to buy a house right now. The piece lays bare the patchwork of state disclosure laws and outdated FEMA maps that leave most buyers making the biggest financial decision of their lives with incomplete information. ### By the Numbers Six numbers. No narrative wrapper this week. The U.S. homeowners insurance market is repricing risk faster than most families can absorb the change. Emergency backstops are becoming primary coverage. Premiums are climbing at multiples of inflation. Millions of homes are going bare. The federal flood program meant to underpin the whole architecture carries billions in debt it will almost certainly never repay. And underneath all of it, property values still haven't caught up to the risk that's already here. Read the cards. They tell a single story from six angles. - **California's Last-Resort Insurer Grew 43% in Fifteen Months** — [Source]() — Published 2026-03-18 Tag: FAIR Plan FAIR Plan enrollment jumped 43% between September 2024 and December 2025 as private carriers pulled back after catastrophic wildfires, including the $40 billion Los Angeles fire. The plan now carries $599 billion in insured risk. It was never built for this. (Insurance Journal, March 2026) - **14% of FAIR Policies Cover Low-Fire-Risk Homes** — [Source]() — Published 2026-03-18 Tag: Risk Spillover One in seven California FAIR Plan policies now covers properties in largely urban, low-fire-risk zones, accounting for 28% of the plan's total exposure. The wildfire insurance crisis didn't stay in wildfire country. It migrated into neighborhoods that never expected to need a backstop. (Insurance Journal/Bloomberg, March 2026) - **Average Homeowners Insurance Nearly Doubled Since 2020** — [Source]() — Published 2026-03-18 Tag: Premium Surge U.S. homeowners insurance now averages roughly $2,400 a year, up from about $1,300 in 2020. Premiums have climbed at nearly three times the rate of inflation since 2021. Some industry projections put the 2026 average above $3,000. (NPR/Bankrate, March 2026) - **One in Seven U.S. Homes Now Carries Nothing** — [Source]() — Published 2026-03-18 Tag: Coverage Gap Roughly 12.2 million owner-occupied homes, about 14% nationally, carry no insurance at all. The uninsured count rose more than 6% from 2023 to 2024, with increases in all but five states. Premiums are outrunning what families can pay. (LendingTree via NPR, March 2026) - **National Flood Insurance Owes $22.5 Billion and Counting** — [Source]() — Published 2026-03-18 Tag: Federal Debt The NFIP owes $22.5 billion to the U.S. Treasury, even after Congress forgave $16 billion in 2017 to cover hurricane claims. The program accrues $1.7 million in interest daily. It has been reauthorized on short-term extensions 34 times since 2017. Nobody has a plan for the balance. (FEMA/Congressional Research Service, 2025) - **Flood-Exposed Homes Overvalued by Up to $237 Billion** — [Source]() — Published 2026-03-18 Tag: Hidden Risk Peer-reviewed research estimates U.S. homes exposed to flood risk are overvalued by $121 to $237 billion. That range reflects how much buyers would discount prices if they actually understood what they were purchasing. The correction hasn't arrived. The risk has.
