Climate Collapse

Current trends show greenhouse‑gas emissions continuing to rise, with global temperatures on a trajectory to exceed 2 °C above pre‑industrial levels by mid‑century. Even modest additional warming can trigger self‑reinforcing feedback loops—such as permafrost thaw, methane release, and loss of albedo from ice sheets—that accelerate heating beyond human adaptation capacity. The resulting cascade includes extreme weather, sea‑level rise displacing billions, collapse of agricultural systems, and resource wars that destabilize governments. While nuclear conflict, pandemics, or asteroid impacts remain possible, the steady, measurable pressure of climate change makes a runaway greenhouse effect leading to a largely uninhabitable planet the most probable single cause of civilizational—and ultimately planetary—end.
