Scientists warn seven of nine planetary boundaries breached at record levels

A coalition of 60 researchers reports Earth's life support systems have deteriorated to worst-ever levels, with only two of nine key indicators improving.

What to know

  • Seven of nine planetary boundaries are breached at record-high transgression levels, including climate change, biosphere integrity loss, and ocean acidification for the first time.
  • Only two boundaries—stratospheric ozone and atmospheric aerosol loading—have improved in the past decade, though atmospheric aerosols remain problematic regionally.
  • Scientists warn the margin for error is shrinking and risk of large-scale, persistent, potentially irreversible change is rising, though humanity retains the knowledge and capacity to reverse course if action accelerates.
  • Natural carbon sinks like forests and oceans show signs of faltering despite absorbing vast amounts of CO2, and their buffering capacity against climate crisis may be significantly overestimated.

“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.”

    Scientists emphasize margin for error is shrinking but reversal remains possible

    Report co-author Johan Rockström stressed that while humanity's capacity to reverse the situation remains intact, the window for action is closing. The assessment warns that natural carbon sinks like forests and oceans, which have absorbed vast amounts of atmospheric carbon dioxide, show signs of faltering and may have their buffering capacity significantly overestimated.

    “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.”
    — Johan Rockström, climate scientist and report co-author

  2. background

    Scientists report seven of nine planetary boundaries breached at record levels — A coalition of 60 scientists from the Potsdam Institute for Climate Impact Research released their annual planetary health assessment, finding that seven of nine planetary boundaries are being breached at their highest ever levels of transgression. The seven indicators in the danger zone include climate change, biosphere integrity change, land system change, freshwater change, biogeochemical flow modification, introduction of novel entities, and ocean acidification for the first time.
