A multinational coalition launches Project Thermostat-stratospheric aerosol injection to rapidly cool the planet and prevent climate tipping points. For six months, it works. Then the unintended consequences hit: the Asian monsoon fails, catastrophic weather disruptions cascade globally, and political pressure forces an abrupt termination of the program. The result is "termination shock"-a year of compressed climate change that applies 50+ years of warming in twelve months, hammering an already-stressed planetary system and triggering compound disasters across every interconnected network humanity depends on.
