If you don't believe the science...
maybe you see a business opportunity.

Your full-service partner in forward-looking coastal acquisition.
Global Warming Real Estate

Imagine the possibilities: new beachfront property blocks — then miles — inland. At today's shoreline, every lobby can be an aquarium. First-floor windows convert to luxurious front doors, with docks.

The good news? Recent policy developments have significantly accelerated the timeline on these opportunities. Whether you're a skeptic, an optimist, or simply a realist who has decided to profit from the inevitable — we are your full-service partner in forward-looking coastal acquisition.

Change is coming sooner than you think. And frankly, faster than we projected in 2006.

Investor Alert · Q1 2025

The recent rollback of coastal building restrictions, withdrawal from international emissions frameworks, and dramatic acceleration of fossil fuel permitting represent what our analysts are calling a "once-in-a-civilization opportunity window." Clients in Miami's back blocks: your patience is about to be rewarded.

Flood Insurance?

Flood insurance was invented in 1968, when floods were considered unusual. We trust you see where we're going with this.

H2O Motors

The SUV you'll actually need.

For decades, Americans were told they needed four-wheel drive for the road ahead. At H2O Motors, we simply updated that promise for the road under water.

Our engineers spent three years perfecting the hull-to-cabin transition. The result is a vehicle that performs with equal confidence at highway speeds and at depth — one that handles flooding not as an emergency, but as a commute.

Conversion Kits

Because adaptation is just renovation by another name.

Your home was built for the world that existed. We sell the parts for the world that's coming.

All kits engineered for standard American residential construction. Timeline flexible — though our supply chain team recommends not waiting until you can hear the water.

SKU: WDC-1
Window-to-Door Conversion Kit
Our flagship. As seen on the home page since 2006.
Reinforced hinged frame, marine-grade weatherstripping, integrated dock bracket (vessels up to 24 ft), and a tasteful brass kickplate engraved with your house number. Finishes: Driftwood, Barnacle, and Optimist White.
SKU: LAC-2
Lobby Aquarium Conversion Kit
Turn your ground floor into the feature, not the problem.
When water enters a lobby uninvited, it's a flood. When water enters a lobby by design, it's an amenity. Tempered glass partitions, submersible LED, filtration, and a curated starter pack of climate-appropriate fish.

Add-on: LAC-2C — brass "Atrium" plaque. $340 flat. Because framing matters.
SKU: RDH-3
Rooftop Dock & Helipad Kit
For properties at a more advanced stage of transition.
When the first floor is fully aquatic and the second floor is managing, the roof becomes your primary outdoor entertaining space. Cleats, bumpers, lighting, optional helipad circle. Regulatory approval varies by municipality; most are currently focused on other things.
SKU: SBR-4
Staircase-to-Boat-Ramp Retrofit
Because you'll want to get in and out smoothly.
A gentle aluminum ramp replaces the bottom three to five steps, angled for easy kayak or dinghy loading. Non-slip. Weight-rated to 800 lbs. Compatible with all H2O Motors models.
SKU: IRM-5
Industrial Remediation Package
For the assets that can't simply get a nicer door.
Those petroleum storage tanks by the river. The chemical plant at grade level. The municipal water treatment facility that is, itself, now underwater. Our Industrial Remediation Division specializes in the relocation of large-footprint infrastructure to higher ground.

Available markets: Gulf Coast, New Jersey Meadowlands, Houston Ship Channel, Sacramento Delta.
SKU: FTP-BUNDLE
The Full Transition Package Most Popular
For the forward-thinking homeowner who prefers to handle everything at once.
Kits 1 through 4, bundled. Plus: a consultation with one of our Transition Specialists, who will walk through your property and identify which features are worth preserving, which are charmingly nautical already, and which should simply be allowed to become reef habitat. Includes a complimentary property re-appraisal reflecting your new waterfront status.

Note: The Full Transition Package is our most popular product in Miami, Houston, and — as of last quarter — Scottsdale.

Arctic Riviera luxury property
A Global Warming Real Estate Portfolio

Arctic Riviera

Sun. Permafrost. Opportunity.

For generations, Siberia, northern Canada, and Greenland were considered... suboptimal. We are pleased to announce that this is changing rapidly.

The Arctic Riviera represents the most exciting new real estate market since the Florida land boom of the 1920s — with better fundamentals and considerably more ice melt. What was once a frozen wasteland is now a frozen wasteland with infrastructure potential, navigable shipping lanes, and, soon, a surprisingly pleasant July.

The best time to buy was yesterday. The second best time is before the next IPCC report.
Investment Thesis

Short the Shoreline

Our investment thesis is simple: the ocean is moving inland. This is, generally speaking, bad for people who live on the current coast. It is, generally speaking, quite good for people who own property a few blocks — or a few miles — behind them.

We call this strategy "Short the Shoreline." It requires no special expertise, no exotic financial instruments, and no particular optimism about the future. Only a clear-eyed understanding of hydrology.

Our portfolio spans the Gulf Coast, Eastern Seaboard, South Florida, coastal California, and select international markets. The Arctic Riviera division handles northern acquisitions. The Extraterrestrial Division handles everything else.

Deregulation Briefing

Recent rollbacks to coastal construction setback rules in Florida, Louisiana, and Texas have opened previously restricted parcels for development. Our team has mapped every affected parcel.

A Thought Experiment

Flood Insurance?

Flood insurance was invented in 1968, when floods were considered unusual. We trust you see where we're going with this.

Here at Global Warming Real Estate, we don't advise against flood insurance. We simply invite you to consider the math. If a premium is priced to cover an unlikely event, and the event becomes likely, the premium must — eventually — reflect that.

At which point you are essentially pre-paying for your own misfortune on a monthly basis.

The National Flood Insurance Program has been quietly raising rates for years. Private insurers have been quietly exiting coastal markets for years. These are not unrelated trends.

Alternative investment strategy: Take the annual flood insurance premium. Invest it in properties two blocks further inland. In ten years, review your portfolio. You're welcome.

Note: This page does not constitute financial or risk management advice. Nothing on this site does. That should be obvious.

Additional note: The math above is not hypothetical. We've run it. We're just being tactful about how directly we say so.
