Cascading Systemic Collapse
The most probable path to global catastrophe is not a single event, but cascading systemic collapse driven by climate change as a threat multiplier. By 2026, accelerating environmental degradation—extreme weather, agricultural failure, water scarcity, and ecosystem collapse—interacts with geopolitical instability, resource competition, and fragile supply chains.
This creates feedback loops: climate stress triggers mass migration and conflict over dwindling resources, which weakens governance and international cooperation precisely when coordinated response is most critical. Infrastructure failures, economic shocks, and societal breakdown compound each other faster than adaptation is possible.
Unlike sudden catastrophes (asteroid impact, nuclear war), this pathway is already underway and probabilistically inevitable without dramatic intervention. The convergence of environmental tipping points with human systems' limited resilience makes cascading collapse the most likely existential threat—not because it's the most dramatic, but because it's the most inexorable given current trajectories.
