Climate Collapse

Human-driven greenhouse gas emissions have pushed the climate system into unprecedented warming, triggering extreme weather events, rapid ice melt, sea‑level rise, and feedback loops such as permafrost methane release. These physical changes are already destabilising agriculture, water supplies, and coastal habitability, prompting mass migrations and fierce resource competition among nations. As climate impacts intensify, they risk overwhelming geopolitical stability, disrupting global supply chains, and causing a cascading breakdown of modern societies, making climate‑driven collapse the most plausible global‑ending scenario in the near term.
