The risk of large-scale, persistent and potentially irreversible change to the world’s climate and eco system is increasing as the planet shatters several vital boundaries.

The latest Planetary Health Check, authored by more than 60 scientists, and produced by the Planetary Boundaries Science Lab at the Potsdam Institute for Climate Impact Research (PIK) has found seven breached Planetary Boundaries continue to worsen as record ocean heat, droughts, floods, wildfires and extreme heat reveal an Earth system under strain.

Researchers said the Planetary Boundaries describe the interconnected Earth-system processes that must remain within safe limits to preserve the planet’s stability and resilience. exceed its boundary in 2025. All seven are now at their highest recorded levels of transgression.

The seven transgressed boundaries are: climate change, change in biosphere integrity, land system change, freshwater change, modification of biogeochemical flows, introduction of novel entities and ocean acidification. Only the stratospheric ozone depletion and atmospheric aerosol loading boundaries have shown improvement over the last decade. However, the authors caution that global progress may mask unsafe aerosol levels persisting in some regions.

“The diagnosis is unambiguous. Pressure is rising across every Planetary Boundary already outside the safe operating space. It means that the risk of large-scale, persistent and potentially irreversible change is increasing, while our margin for error in tackling these problems is shrinking,” commented Boris Sakschewski, PIK scientist and lead author of the report.

“We do not have the luxury of time, but we do have the knowledge, capacity and solutions to change course. Accelerating action to return to the safe operating space across all Planetary Boundaries is essential to protect lives and livelihoods, and to deliver on the promise of shared future prosperity,” said Johan Rockström, PIK Director and co-author of the report.

The report comes after 12 months marked by extremes across land and oceans. Human-caused warming intensified several major weather extremes, while degraded ecosystems, water stress, land-use change, exposure and social vulnerability often magnified their impacts.

Pakistan’s 2025 monsoon floods affected more than 6.9 million people. Global ocean heat content reached a new record in 2025, with Hurricane Melissa rapidly ramping up to a Category 5 Hurricane and striking Jamaica after passing over exceptionally warm seas. January 2023 to September 2025 saw bleaching-level heat stress impacting approximately 84.4 percent of the world’s coral reef area, making it the largest global coral-bleaching event observed to date.

This year, Western Europe experienced its hottest June-July period on record, accompanied by drought across France, Spain, Germany and the United Kingdom, with major wildfires across Europe and Canada. Record-breaking heat was also recorded in Japan, South Korea and parts of the Middle East.

Hindou Oumarou Ibrahim, chair of the Planetary Guardians said, “Read that list again: Pakistan, the Caribbean, Europe, the reefs beneath our oceans. These are not separate emergencies; the planet is telling us, in every region at once, that it is out of balance. As chair of Planetary Guardians, I hear this same story wherever I go, whether from a pastoralist watching the rains fail season after season or a coastal community watching the sea rise. The 2026 Planetary Health Check puts data behind what communities on the frontlines already know from living it. We do not have the luxury of treating these as separate crises any longer.”

“Any kind of movement requires patience, trust, and the will to keep going, even when it may be easier to stop. The 2026 Planetary Health Check tells us we need that same collective resolve now, applied to the whole planet. Seven of nine boundaries are broken, and no single nation can restore them alone; this is a peace process the entire world must commit to, together, starting now,” concluded Juan Manuel Santos, former president of Colombia and co-vice chair of the Planetary Guardians.
