Climate Catastrophe
Based on accelerating global trends, the most likely world-ending scenario is a cascading climate catastrophe. Rising temperatures, driven by unchecked greenhouse gas emissions, are projected to exceed 3°C by 2100, triggering irreversible tipping points like melting permafrost, collapsing ice sheets, and disrupted ocean currents.
This would lead to widespread societal collapse through mega-droughts, crop failures, and mass migrations, exacerbating geopolitical conflicts over resources. Extreme weather events, biodiversity loss, and sea-level rise could displace billions, overwhelming infrastructure and economies.
Compounded by technological reliance on vulnerable systems and societal divisions hindering global cooperation, this environmental domino effect poses the highest probability of ending human civilization as we know it, outpacing other risks like AI or nuclear war in current trajectories.
