Wave colour guide
What each wave colour means
The combined index determines the wave’s colour, height and movement. Lower scores represent greater pressure.
Guarded
65–79
Yellow-green means meaningful risks require close attention.
Strained
Current
50–64
Orange means combined pressure is elevated and worsening in important areas.
Critical
35–49
Red means severe combined environmental and human pressure.
Extreme
0–34
Dark violet means the combined state has entered the most dangerous range.

Planetary stability
Seven of nine planetary boundaries are outside the safe operating space.
Human wellbeing
Progress is uneven and several foundations of human wellbeing remain off track.

Crime & personal safety
Intentional homicide is used because broader crime reporting is not sufficiently comparable worldwide.
Intentional homicides per 100,000: 5.2
Limitation: Recorded crime differs between countries. Homicide is the most comparable global measure, but it does not represent every form of criminality.

How to read the index
Two equal pillars
Planetary stability and human wellbeing each contribute 50%, so neither can conceal damage in the other.
Versioned normalisation
Human inputs use published targets and fixed extreme bounds. Planetary boundaries use a documented risk-band mapping when a globally comparable numeric series is unavailable. The formula version is stored with every snapshot.
Evidence before AI
Code calculates the score. AI may explain a verified change, but unsupported text cannot alter the public pulse.
Honest freshness
Sources are checked daily, while each card shows the actual evidence period. Missing data retains its last verified value and is marked stale.
