Terrarium.
A Global Emotional Index
The world's emotional temperature, read daily — and remembered. The record does not reset.
Memory
A century of emotional temperature.
1925 to 2025.
1925–2024 is an interpretive record, written by hand — not data.
The living record begins below.
The world holds its breath between storms, watching for the light that keeps arriving anyway.
Everything above this line is interpretation. From today forward, each daily reading is archived permanently — the record becomes real one day at a time.
Seven Climates
Each dimension measures a distinct axis of planetary health, scored from −100 to +100.
Once a day, Claude searches current headlines, synthesises what it finds, and returns a score for each region and dimension. No human curates the result. The model reads the news so you can feel it.
Every reading is archived, never overwritten. Yesterday exists here. That is the difference between a dashboard and a terrarium: a dashboard resets — an ecosystem remembers.
The global score is the average of six regional scores, weighted equally — a crisis in the Middle East matters as much as a breakthrough in Oceania.
The index measures seven axes of collective human experience. Six describe the weather. The seventh — Resilience — watches for healing: it scores recovery in motion, not the absence of damage.
Stability
Political order, governance resilience, absence of conflict escalation.
MEASURED BY — Coups, ceasefires, elections held or stolen, governments forming or collapsing.
Cooperation
Multilateral agreements, diplomatic progress, cross-border solidarity.
MEASURED BY — Treaties signed, summits producing commitments, aid corridors opening, joint missions.
Progress
Scientific advances, humanitarian milestones, long-term systemic gains.
MEASURED BY — Scientific firsts, health milestones, access and rights expanding.
Crisis
Active emergencies, displacement events, humanitarian crises in motion.
MEASURED BY — Casualties, displacement, disaster declarations, famine warnings. Inverted: more crisis, lower score.
Economic Vitality
Trade flows, employment signals, financial system health, equitable growth.
MEASURED BY — Employment, market stability, trade volumes, inflation cooling or biting.
Social Energy
Civil society activity, cultural momentum, collective human expression.
MEASURED BY — Protests, turnout, strikes, festivals — the civic pulse, in either direction.
Resilience
Recovery in motion — rebuilding, aid arriving, ceasefires holding, communities adapting. Healing, not the absence of damage.
MEASURED BY — Reconstruction starting, refugees returning, institutions repairing. Calm is not resilience — only recovery counts.
Calibration
Scores are relative to the rolling norm of world news, not to utopia. Zero is an ordinary mixed week. ±40 means one story dominates a region. ±80 is historic — a war ending, a state collapsing — and most years never touch it. A score is only allowed to move sharply when something material actually happened.
What this is not
The index reads news coverage — the world's nervous system as reported, not the private lives of eight billion people. A quiet good day rarely makes headlines. Treat every reading as a portrait of attention, weighted toward what the world noticed.
