Seven of Earth’s nine planetary boundaries are being breached at their highest levels ever recorded, according to a report released on Monday. The assessment, established in 2009 and conducted under the auspices of the Potsdam Institute for Climate Impact Research by a coalition of 60 scientists, warns that planetary life support systems have deteriorated to their worst levels ever recorded amid ongoing pollution and habitat destruction.
Planetary Health Check Warns of Record Breaches
The report details that the seven indicators currently in the danger zone are climate change, change in biosphere integrity, land system change, freshwater change, modification of biogeochemical flows, introduction of novel entities, and ocean acidification, which was breached for the first time last year. Only two assessed areas, stratospheric ozone depletion and atmospheric aerosol loading, have shown improvement over the past decade, though researchers note that atmospheric aerosols remain a problem in multiple regions.
The diagnosis is unambiguous – pressure is rising across every planetary boundary already outside the safe operating space,
said Boris Sakschewski, lead author of the report.
Ecosystem Strains and Global Implications
Habitats including forests and wetlands are being fragmented, torn apart, and flattened for urban areas and agriculture, which imperils animal species and natural systems. The report warns that the ability of landscapes and bodies of water to act as a buffer against the worsening climate crisis is weakening and may be significantly overestimated. While oceans and forests have absorbed massive amounts of carbon dioxide, natural systems are showing signs of faltering.
As an example, researchers stated that the Amazon rainforest could potentially reach a tipping point and transition into a savannah, carrying serious implications for food and water security, human health, and climate stability worldwide. The report arrived shortly after the start of Climate Week in New York City, a major gathering of activists, business leaders, and politicians leading up to the United Nations general assembly.
