Climate Catastrophe

By 2026, accelerating climate change—driven by unchecked emissions, deforestation, and industrial activity—remains the most probable path to global collapse. Rising temperatures have already intensified extreme weather, leading to widespread crop failures, water shortages, and mass migrations. Without drastic mitigation, feedback loops like melting permafrost releasing methane could push the planet past tipping points by mid-century.

This scenario wouldn't end all life instantly but could cascade into societal breakdown: famines spark conflicts over resources, weakening governments and economies. Billions might perish from starvation, disease, and violence, potentially leading to human extinction or a drastically reduced population in a hostile environment. Geopolitical tensions exacerbate this, as nations compete for dwindling habitable land, but no other trend matches climate's inevitability and scale without intervention.
