Climate Collapse

Based on current trajectories, climate change represents the most probable singular pathway to global catastrophe. Rising temperatures are triggering irreversible feedback loops—permafrost thaw, methane release, ocean acidification, and ecosystem collapse. These changes compound to disrupt food production, water security, and habitable zones, driving mass migration, resource conflicts, and political instability. While other threats like nuclear war or AI remain dangerous, climate change is already occurring and will worsen progressively unless massive, coordinated global action occurs. Its simultaneous impact across all nations makes it the most likely singular cause of systemic global collapse within this century.
