Climate-Driven Systems Collapse

The most probable end is a cascading failure. Accelerated climate change pushes key planetary systems—like polar ice melt and oceanic currents—past irreversible tipping points. This triggers catastrophic, simultaneous harvest failures, leading to global famine. Massive, unmanageable human migration from uninhabitable zones overwhelms nations, fueling resource conflicts and the collapse of international cooperation. Strained by supply chain paralysis and political fragmentation, the global economy shatters. This slow, grinding collapse of the biosphere and civilization, where environmental crisis begets geopolitical and societal ruin, proves more relentless than any single war or technological failure.
