From satellites circling the Earth, to weather stations far out in the ocean, through some of the most ingenious minds and advanced algorithms at work today - In this gripping investigation, Andrew Blum takes us on a global journey. Our destination: the simulated models weather scientists have constructed of our planet, which spin faster than time, turning chaos into prediction, offering glimpses of our future with eerie precision. This collaborative invention spans the Earth and relies on continuous co-operation between all nations – a triumph of human ingenuity and diplomacy we too often shrug off as a tool for choosing the right footwear each morning. But in this new era of extreme weather, we may come to rely on its maintenance and survival for our own.
