Integrating the planetary boundaries and global catastrophic risk paradigms

摘要: Planetary boundaries (PBs) and global catastrophic risk (GCR) have emerged in recent years as important paradigms for understanding addressing threats to humanity the environment. This article compares PBs GCR integrates them into a unified PBs-GCR conceptual framework, which we call Boundary Risk Humanity Nature (BRIHN). emphasizes environmental threats, whereas human civilization. Both rate their top priorities but lack precision on key aspects of impacts threats. Our integrated BRIHN framework combines elements from both paradigms' treatments uncertainty impacts. The offers means handling theoretically precise definition catastrophe. also concise stage telling stylized version story nature co-evolving distant past present multiple possible futures. is illustrated using case disruptions phosphorus biogeochemical cycle.
