Method and sources

Method, rules and sources

This page explains the evidence, sources, interpretation limits, and supporting context behind the story. The core evidence comes from official climate and disaster datasets; CPI/inflation and real-life reports provide supporting context only.

Evidence and method

How the pressure chain is built

The method separates official climate and disaster evidence from supporting cost-of-living and real-life context. It treats the story as a pressure-chain interpretation, not a single-variable causation model.

01

Core evidence

Sea level, rainfall, disaster loss, affected persons, and crop yield form the core evidence chain.

02

Supporting context

CPI/inflation frames household pressure only. It is not treated as proof of direct causation.

03

Country comparison

Rankings use available reported totals and should not be read as a complete vulnerability measure.

04

Interpretation guardrail

The story shows connected pressure, not a single-variable attribution model.

Evidence principles

How to read this story

The visualisation combines official indicators with supporting context while keeping the limits of the evidence visible.

Official indicators

Sea level, rainfall, crop yield, direct disaster loss, and people directly affected form the core evidence base.

Supporting cost context

CPI and inflation provide household-cost context and are not presented as proof of direct climate-to-price causation.

Available records

Country comparisons use the records available in each dataset. Missing values do not mean that a country has no exposure.

Connected pressure

The story describes a plausible pressure chain across systems, not a single-variable attribution model.

AI usage statement

AI-supported implementation and refinement.

AI assistance was used for coding support, wording refinement, layout iteration, troubleshooting, and the creation of illustrative scene images. The illustrations are not presented as documentary photographs. Dataset selection, analysis, story framing, interpretation limits, design decisions, and validation remained human-directed.
