Seven of the nine planetary boundaries that determine whether life can flourish on Earth are being breached at their highest ever recorded levels, scientists have warned in a stark annual health check of the planet's life support systems.
The planetary boundaries framework, established in 2009, tracks nine key indicators of Earth's stability., reports The Guardian.
The seven now in the danger zone are climate change, biosphere integrity, land system change, freshwater change, biogeochemical flows, novel entities such as plastics and chemicals, and -- added for the first time last year -- ocean acidification.
Only stratospheric ozone depletion and atmospheric aerosol loading have shown improvement over the past decade.
The assessment, conducted by a coalition of 60 scientists under the Potsdam Institute for Climate Impact Research, warns that the consequences of breaching these boundaries are becoming increasingly visible worldwide.
"The diagnosis is unambiguous -- pressure is rising across every planetary boundary already outside the safe operating space," said lead author Boris Sakschewski.
"The risk of large-scale, persistent and potentially irreversible change is increasing, while our margin for error is shrinking."
The driving forces are well established: fossil fuel burning, mass plastic pollution, and the destruction of forests and wetlands for agriculture and urban expansion.
Natural buffers such as forests and oceans, which have absorbed vast amounts of carbon dioxide, are showing signs of strain.
Scientists warn that the Amazon rainforest could reach a tipping point and convert into savannah, with severe consequences for global climate, food and water security.
The report follows a year of extreme weather events, including devastating floods in Pakistan, record heat and wildfires across Europe, the hottest ever summer in the United States and a catastrophic flood on the Tibet-Nepal border.
Despite the dire outlook, climate scientist and report co-author Johan Rockström said humanity still has the knowledge and capacity to act. "Accelerating action to return to the safe operating space across all planetary boundaries is essential to protect lives and livelihoods," he said.
