Climate Collapse

Current trajectories show relentless greenhouse‑gas emissions, accelerating ice‑sheet melt, and worsening extreme‑weather events. Feedback loops—such as permafrost thaw, Amazon forest die‑back, and methane release from hydrates—risk pushing Earth into a hothouse state. The resulting sea‑level rise, chronic food‑ and water‑ insecurity, and massive climate‑driven migrations would overwhelm nations, strain resources, and intensify geopolitical competition. While other existential threats (nuclear war, AI misalignment, pandemics) remain possible, the steady, observable nature of climate change makes it the most probable catalyst for a systemic civilizational breakdown that could ultimately end the world as we know it.
