Understanding Nuclear Weapons and Their Global Impact

Physicist Max Tegmark discusses the severe risks posed by nuclear weapons, emphasizing the threat of a nuclear-induced winter that could devastate the global food system. Despite reductions post-Cold War, the US and Russia still possess enough nuclear weapons to cause such a winter. Accidental nuclear war remains a significant risk due to past close calls. Tegmark argues that excessive nuclear arsenals are a security threat and advocates for public action through divestment from companies involved in nuclear weapons production.
