Carlo Rovelli warns of 'Edge of Armageddon' in new book

scienceJun 25, 2026867

In Edge of Armageddon and a Guardian interview, theoretical physicist Carlo Rovelli warns the world is edging closer to nuclear catastrophe, saying current leaders "chronically lack the nous of Kennedy." Rovelli attributes the heightened danger to renewed great-power tensions and the modernization of nuclear arsenals, which he says increase the risk of miscalculation and accidental escalation. He revisits Cold War near-misses to show how existing command-and-control vulnerabilities could make a single error catastrophic. The book is framed as an urgent call to revive concrete arms-control diplomacy and public pressure to avert that outcome.
