Climate Collapse

The most probable existential threat is not a single event but a cascading failure triggered by irreversible climate change. By 2026, observable tipping points (Arctic ice loss, Amazon dieback, permafrost thaw) are being crossed, accelerating warming beyond current models. This leads to systemic collapse: chronic global food and water shortages, mass migration, and resource conflicts destabilizing nations simultaneously. Feedback loops, such as methane release from thawing permafrost, could push the climate into a Hothouse Earth state by 2100, rendering large parts of the planet uninhabitable. While technological solutions exist, geopolitical fragmentation and societal inertia are preventing the necessary coordinated global action at the required speed and scale.
