Climate Collapse

Accelerating global warming, driven by unmitigated emissions and feedback loops (e.g., permafrost methane release, albedo loss from melting ice), will surpass critical thresholds. This will trigger cascading system failures: simultaneous crop failures across breadbasket regions, chronic freshwater shortages, and deadly heatwaves rendering large areas uninhabitable. Mass displacement and resource scarcity will fracture global supply chains, fuel geopolitical conflict, and overwhelm governance structures, leading to a gradual but irreversible disintegration of civilization. While not extinguishing all life, this collapse of the human world system—through famine, war, and state failure—represents the most probable end-of-world scenario given current trajectories.
