AdaptBase
Organizing the world’s climate adaptation knowledge.

Climate adaptation is atrillion-dollar challenge.

Today the world spends $190 billion a year defending 1.2 billion people to developed-economy standards. Protecting everyone exposed to climate hazards would cost $540 billion.

McKinsey Global Institute, 2025 →

We’ve read 115 adaptation plans from 86 cities in full — cataloging 13,204 actions and 101 common solutions.

How will you use this knowledge to make better decisions about adaptation investments and innovations?

How it’s built

AdaptBase sources and organizes knowledge scattered across the web.

Our custom-engineered AI agents discover documents detailing adaptation plans, actions, implementation and outcomes.

Miami-Dade County Extreme Heat Action Plan
ACTION 18: Pilot and scale cool pavements

Conduct pilots of different types of cool pavements in low-impact areas, such as walkways, bike paths, parking lots, and low-volume roads…

Cool pavement could either be permeable, allowing water and water vapor into the voids of the pavement that keep it cooler when moist, or it could be more reflective than standard pavement, reducing incoming solar radiation and cooling the air temperature.

We collect the facts that matter.

Using an ontology developed with adaptation and resilience experts, we extract structured evidence — so every document reporting on every city and company is read in a rigorous, standardized way. No chatbot guessing from a pile of PDFs.

One line in one city’s PDF becomes a fact you can count, compare and trace — against every other plan we’ve read.

Deep research

This is only the start.
We deploy autonomous AI agents to expand, update and fill gaps in our knowledge.

EXPAND THE GRAPH
“Which startups are building technology-enabled solutions for extreme heat?” No city plan answers that, and we hold zero suppliers today — so the researcher leaves the library and works the open web.
→ new sources acquired
EXTRACT STRUCTURED DATA
“Build the financing timeline across every capital project we know of.” 93 projects, 163 financial instruments — the same graph, at far higher resolution.
→ queued
CONTINUOUSLY UPDATE AND REFINE
“Does anything that just landed change what we already hold?” Every document the researcher pulls is read against the whole graph, not only the task that fetched it. A Rotterdam report retrieved for a cooling-centre question revised a rooftop water-storage action we'd held as planned since 2021 — now 34 buildings delivered.
