Climate Collapse

The most likely global catastrophe is runaway climate change triggering systemic collapse. Accelerating feedback loops—such as permafrost thaw, Amazon dieback, and ice sheet loss—are pushing the system past irreversible tipping points faster than predicted. This would lead to simultaneous failures in global food production from droughts/floods, mass displacement from sea-level rise and uninhabitable zones, and conflicts over dwindling resources. The interconnectedness of modern civilization means cascading failures in supply chains, economies, and political stability could cascade into a domino effect, overwhelming adaptive capacities and leading to a fragmented, inhospitable world.
