Climate Catastrophe
Based on accelerating global trends, the most likely world-ending scenario is a cascading climate catastrophe driven by unchecked environmental degradation. Rising temperatures, extreme weather events, and biodiversity loss are already disrupting food systems, water supplies, and habitable zones, with projections indicating billions displaced by 2050.
Geopolitically, resource scarcity exacerbates conflicts over arable land and water, potentially escalating into wars that compound the crisis. Technological advancements in renewables lag behind emissions growth, while societal denial and inequality hinder unified action.
This could culminate in a tipping point, such as irreversible ice sheet melt or ocean acidification, leading to mass extinction and societal collapse, effectively ending human civilization as we know it.
