Climate Collapse

The most probable global catastrophic scenario is runaway climate change surpassing irreversible tipping points. Accelerating feedback loops—such as permafrost methane release, ice sheet collapse, and forest dieback—could push planetary systems into a state incompatible with organized human civilization. Current trends show emissions remaining high, adaptation efforts lagging, and interconnected vulnerabilities across food, water, and energy systems.

This would not be a single sudden event but a cascade of crises: widespread crop failures, extreme weather disasters, mass migration, and resource conflicts. The resulting global instability could overwhelm political and economic systems, potentially leading to systemic collapse. While other risks exist, climate change is already measurable, accelerating, and lacks a coordinated global solution at the necessary scale.
