Planetary Boundaries Science, an initiative from The Potsdam Institute for Climate Impact Research (PIK) and with support from the Planetary Guardians and other stakeholders, has released the first Planetary Health Check, an annual scientific report which measures our current position within the nine planetary boundaries, a concept coined by the Stockholm Resilience Centre. Since 2023, scientific reports have found that six out of the nine Planetary Boundaries have been transgressed. The Planetary Health Check’s headline finding is that a seventh boundary, Ocean Acidification, has now been breached.

The CLIMAR Network uses the Planetary Boundaries concept to examine the relationship between AMR, climate change, pollution, biodiversity and other drivers.
CLIMAR lead Professor Will Gaze said “This announcement, that we have breached a further Planetary Boundary, Ocean Acidification, as well as increased our transgressions past several others ,makes what we are trying to achieve through the CLIMAR Network all the more pressing. We will shortly be putting together Working Groups looking specifically at five of these boundaries and how they interact with the rising tide of antimicrobial resistance, with the short-term aim of assembling policy briefs and identifying key knowledge gaps in such an underexplored area of intersection.”
