Climate Collapse

The convergence of accelerating climate change effects with humanity's inadequate response makes this the most probable systemic failure. Rising global temperatures are exceeding optimistic projections, leading to more severe and frequent extreme weather events (droughts, floods, heatwaves, storms). This disrupts global agriculture, reduces freshwater availability, triggers mass migration, and destabilizes economies. Feedback loops, such as melting permafrost releasing methane, could irreversibly accelerate warming. While geopolitical conflicts or technological risks are severe, climate collapse uniquely imposes a slow but relentless, planet-wide pressure that strains all human systems—food, water, energy, and social cohesion—to a breaking point. The cascading failures across these interconnected systems present the greatest single-cause existential threat.
