Climate Collapse

The single most probable cause is the cascading failure of global systems triggered by rapid, irreversible climate change. Accelerated warming will exceed critical tipping points—such as the collapse of key ocean currents or the die-off of the Amazon rainforest—leading to runaway environmental disruption.

This will directly cause catastrophic food and water shortages through prolonged droughts, extreme weather events, and sea-level rise inundating coastal cities. The ensuing resource scarcity will overwhelm governance, triggering mass migration, societal breakdown, and intensified geopolitical conflict over habitable land and essentials. Our interconnected, optimized global supply chains and political systems lack the resilience to absorb such simultaneous, worldwide shocks, leading to a failure of modern civilization.
