Climate Collapse

Based on trajectory, the most likely catastrophic outcome is a cascading failure of Earth's climate systems, rendering large swathes of the planet uninhabitable and triggering global societal collapse. Feedback loops like permafrost thaw and reduced ice albedo are accelerating warming beyond models, leading to consecutive crop failures, extreme water scarcity, and mass displacement. These pressures would overwhelm political and economic systems, fueling conflict over dwindling resources. The resulting breakdown of global cooperation would prevent any coordinated mitigation, leading to a self-reinforcing cycle of environmental degradation and civilizational failure.
