Runaway Climate Feedback

Multiple accelerating feedback loops—permafrost thaw, Amazon dieback, and Arctic ice loss—trigger unstoppable global warming beyond 3°C by 2100. Extreme heatwaves, collapsing food systems, and ecosystem failures displace billions, overwhelming societal stability. Resource scarcity fuels geopolitical conflicts, while climate-driven migration spreads pandemics and economic collapse. Governments fail to coordinate responses as cascading disasters exceed adaptive capacity, making recovery impossible. Unlike nuclear war or pandemics, climate tipping points are already partially irreversible and self-reinforcing, with no feasible mid-century reversal under current trajectories.
