The Blood Test

Like a patient's lab results: all 14 vital signs read against their safe limits for 2026, grouped under the nine Planetary Boundaries they belong to.

The Spider Diagram

The whole planet at a glance. Each wedge grows outward as its boundary is pushed harder — the further past the green safe ring it reaches, the deeper the trouble. Run the clock beneath the figure to watch the wedges grow out of the Holocene.

The Planetary Boundaries

Nine guardrails that keep Earth stable enough to remain a safe home for life — and for us.

Human activity has pushed Earth beyond its Safe Operating Space, and the planet's ability to absorb that pressure is wearing thin. Warming is speeding up, ecosystems are visibly fraying, and several key systems are showing the first warning signs of tipping points — thresholds that, once crossed, are very hard to walk back. We have entered the Anthropocene: a time when human activity has become a force shaping the whole Earth system.

To keep the planet stable, we have to bring it back inside its Planetary Boundaries — the nine scientifically defined guardrails that hold Earth in a healthy, liveable state. Stay within them, and the planet remains our dependable home; cross them, and we risk lasting damage to the very life-support systems we all depend on. Today, seven out of nine boundaries have been breached. The two still safe are no accident: the ozone layer, once thinning fast, is healing today because the world agreed to ban the chemicals destroying it — proof that these limits can be defended when we act together.

The Planetary Health Check is a yearly check-up on the state of the planet. It brings together the latest scientific assessment of each Planetary Boundary, explains the science behind them in plain language, and highlights the changes that matter most for Earth's health right now. Like any check-up, its purpose is not the diagnosis — it is what we do next.

Figures

Interactive versions of the report's key charts.

Figure · Temperature Humanity's Journey Half a million years of global temperature — the deep ice ages, the stable Holocene in which civilization arose, the modern spike and the Great Acceleration — as one interactive timeline. Open Figure · 1750–2024 The Great Acceleration Twenty-four indicators of human activity and the Earth system, each a panel in one woven figure. Switch between cumulative charts and the warming-stripes art cut; the colour reads as cumulative progress. Open Figure · Boundary interactions PB Interconnections Sixty-four processes by which one planetary boundary changes another, drawn as a single ring. HoverTap a boundary to isolate everything it touches, or one arc to read the process behind it — its effect, how far it reaches, what evidence stands behind it and the literature it came from. Open Figure · Temperature Deep time to deep future Twenty-four thousand years of global temperature — from the Last Glacial Maximum through the stable Holocene to the Anthropocene spike, then the futures: three CLIMBER-X pathways to the year 3000, or the seven CMIP7 scenarios to 2500.

The Planetary Health Check is the annual assessment of the nine Planetary Boundaries, produced by the Planetary Boundaries Science Lab at the Potsdam Institute for Climate Impact Research. Every reading on this page comes from its 2026 control-variable dataset — the same numbers, the same method, nothing added and nothing smoothed.

GLOBAÏA built the companion: the figures you can open, explore, download and cite. The assessment itself, the full 2026 report and the science behind each boundary live at planetaryhealthcheck.org.
