One half of the 10-million Swedish crown (1.15 million USD) prize goes in equal parts to Manabe, 90, and Hasselmann, 89, for modelling earth’s climate and reliably predicting global warming.

The other half goes to Parisi for discovering in the early 1980s "hidden rules" behind seemingly random movements and swirls in gases or liquids that can also be applied to aspects of neuroscience, machine learning and starling flight formations.

"Syukuro Manabe and Klaus Hasselmann laid the foundation of our knowledge of the Earth’s climate and how humanity influences it," the Royal Swedish Academy of Sciences said in a statement. "Giorgio Parisi is rewarded for his revolutionary contributions to the theory of disordered materials and random processes.”
