Climate Collapse

The most probable path to global civilizational collapse is unmitigated climate change. Despite incremental progress, greenhouse gas emissions continue to rise, locking in severe warming. This triggers cascading tipping points—Arctic permafrost thaw releasing methane, Amazon rainforest dieback, and ice sheet disintegration—accelerating warming beyond human control. Widespread crop failures, freshwater scarcity, and coastal inundation displace billions, igniting resource wars and nuclear brinkmanship. Complex supply chains fracture, economies unravel, and governance fails. The ultimate blow is not a single event but a systemic unraveling: famine, pandemics from thawing pathogens, and societal collapse feed on each other, rendering large-scale human organization impossible. This is not extinction, but the end of the world as we know it.
