Humanity has thrived for over 10,000 years within a period of climatic stability and a resilient Earth system, which has allowed the development of advanced technologies and cultures. However, as the 2024 PHC report shows, we are now entering a dangerous new era marked by increasing symptoms of PB transgressions, such as more frequent extreme weather events, wildfires, reduced plant productivity, and water scarcity. These challenges are compounded by a still-growing global population that must navigate unprecedented difficulties. Beyond these immediate concerns, a more profound threat lies in the gradual weakening of Earth system resilience. As we approach — and potentially cross — critical tipping points (5), these slow changes may not result in abrupt shifts but could lead to irreversible trends, such as accelerated sea-level rise and self-reinforcing pathways that move us further from the stable, Holocene-like conditions crucial for human life.Planetary Health CheckA Scientific Assessment of the State of the PlanetExecutive Summary, (2024) p4.
