Climate-Induced Nuclear Conflict

Accelerating climate change will push critical environmental systems past irreversible tipping points, disrupting global agriculture and fresh water supplies. This ecological shock will trigger massive climate migrations and the collapse of vulnerable states, placing unprecedented strain on the global geopolitical order. As major powers compete for dwindling habitable land, food, and water, regional conflicts will inevitably escalate into direct great-power confrontations.

Under the extreme stress of global resource scarcity and societal breakdown, the fragile frameworks of nuclear deterrence will erode. A conventional war over essential survival resources will eventually cross the nuclear threshold. A full-scale strategic nuclear exchange would not only destroy critical infrastructure directly but also trigger a prolonged nuclear winter. The resulting blockade of sunlight would halt photosynthesis, collapse remaining global food chains, and ultimately lead to the extinction of humanity.
