About the Indices

Earth Doom Index is a toy project that collects and aggregates daily threat signals from four domains — Society, Climate, Economy, and Solar — and combines them into a single 0–100 composite doom score. Society is measured from GDELT news data, tracking the frequency and intensity of protests, armed conflicts, and terrorism events happening around the world. Climate draws from OpenWeather across 7 anchor cities spread across continents, detecting extreme heat, cold snaps, and severe storm conditions. Economy monitors 5 market stress signals via Yahoo Finance — VIX volatility, S&P 500 daily change, S&P 500 1-year drawdown, HYG 1-year drawdown, and yield curve inversion (10Y − 3M) — as a proxy for systemic financial strain. Solar pulls Kp index readings and X-class solar flare alerts from NOAA SWPC, measuring space weather threats to Earth's magnetosphere and critical infrastructure.

"How doomed is Earth today?" — it's a half-joking question, but this index tries to answer it with real data every single day. The score and risk tier are recalculated once daily, compressing concurrent macro-level signals into a single number anyone can glance at. The weighting is deliberate: a single domain spiking in isolation — say, a turbulent day in equity markets, or an elevated Kp index from a passing geomagnetic storm — nudges the overall score only modestly. The composite rises meaningfully only when multiple domains deteriorate at the same time, because that convergence is what actually makes the world feel like it's unraveling.

Curious how each domain converts raw data into a threat score? Click the cards below to see the data sources and conversion formulas for each domain. How those four scores are then aggregated into the 0–100 composite and assigned to one of six risk tiers — from PEACEFUL ILLUSION at the low end up through OUTCOME IS CLEAR at the top — is explained in full on the methodology page. One important caveat: this index is not designed for academic research, policy decisions, or investment decisions, and the numbers carry no scientific or legal weight whatsoever. This is, ultimately, a toy project. Take it as a playful tool, nothing more.
