Human activities have pushed Earth
beyond its
Safe Operating Space. The planet's natural resilience is weakening: Global warming is accelerating, ecosystems are showing clear signs of degradation, and early warning signs of tipping points are emerging in key systems. We have entered the Anthropocene — an era where human activity dominates the Earth system.
To safeguard the Earth's resilience and stability,
we must bringthe
planet back into its
Planetary Boundaries. These boundaries are scientifically defined guardrails that ensure the Earth's health. Stay within them, and the Earth stays our dependable home — breach them, and we risk irreversible damage to our very own life support system. Today, seven out of
nine boundaries have been
transgressed.
The Planetary Health Check is a yearly report on the state of our planet. It presents the most up-to-date assessments of the Planetary Boundaries, gives thorough introductions into cutting-edge science, and spotlights especially relevant aspects of our planet's health. In this 2026 edition, we place a special focus on carbon sinks and novel entities.
