Climate System Collapse

Rising global temperatures are pushing Earth past critical tipping points—melting permafrost releasing methane, Amazon rainforest dieback, and collapsing ice sheets—each amplifying warming further. By mid-century, these cascading feedback loops could destabilize agriculture, trigger mass famines, and provoke resource wars among nuclear-armed states. Societal fragmentation prevents coordinated mitigation as vulnerable regions collapse into conflict. The result: irreversible civilizational decline within decades, even if not immediate human extinction. Current emission trajectories make this scenario more probable than all other existential risks combined.
