Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi to share Physics Nobel 2021

The Royal Swedish Academy of Sciences has announced the 2021 Nobel Prize in Physics to Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi “for groundbreaking contributions to the understanding of complex physical systems.”

Stockholm:The Royal Swedish Academy of Sciences will award the 2021 Nobel Prize in Physics to Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi “for groundbreaking contributions to the understanding of complex physical systems.”

According to an announcement made by the Nobel Prize, Manabe and Klaus have been jointly awarded one half of the 2021 #NobelPrize in Physics “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming.”

Meanwhile, Parisi has been awarded one half of the prize “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.”

A statement by the Nobel Prize on Twitter said the prize for physics recognises new methods for describing complex systems and predicting their long-term behaviour. One complex system of vital importance to humankind is Earth’s climate.

Manabe was awarded the Nobel Prize for his model demonstrated how increased levels of carbon dioxide in the atmosphere lead to increased temperatures at the surface of the Earth. "His work laid the foundation for the development of current climate models.," the statement by the Nobel Prize said.

Hasselmann, the Nobel Prize said, "created a model that links together weather and climate."

"His methods have been used to prove that the increased temperature in the atmosphere is due to human emissions of carbon dioxide," it added.

Parisi won the prize for discovering "hidden patterns in disordered complex materials."

"His discoveries are among the most important contributions to the theory of complex systems," the Nobel Prize tweeted.
