SRINAGAR: The Royal Swedish Academy of Sciences gave the Nobel Prize for Physics to be shared between three scientists. One half of the award was given jointly to Syukuro Manabe and Klaus Hasselmann and the other half to Giorgio Parisi.

Manabe and Hasselmann were awarded the prestigious prize for “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming” while Parisi was awarded the Nobel for “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.”

As per the statement issued by the Nobel Prize Organization on their website, this year’s Nobel for Physics was awarded “for groundbreaking contributions to our understanding of complex physical systems.”

“Three Laureates share this year’s Nobel Prize in Physics for their studies of chaotic and apparently random phenomena. Syukuro Manabe and Klaus Hasselmann laid the foundation of our knowledge of the Earth’s climate and how humanity influences it. Giorgio Parisi is rewarded for his revolutionary contributions to the theory of disordered materials and random processes,” read the statement on their website.

Thors Hans Hansson, chair of the Nobel Committee for Physics in his statement said, “The discoveries being recognised this year demonstrate that our knowledge about the climate rests on a solid scientific foundation, based on a rigorous analysis of observations. This year’s Laureates have all contributed to us gaining deeper insight into the properties and evolution of complex physical systems.”

One complex system of vital importance to humankind is Earth’s climate. Syukuro Manabe demonstrated how increased levels of carbon dioxide in the atmosphere lead to increased temperatures at the surface of the Earth. In the 1960s, he led the development of physical models of the Earth’s climate and was the first person to explore the interaction between radiation balance and the vertical transport of air masses. His work laid the foundation for the development of current climate models.

About ten years later, Klaus Hasselmann created a model that links together weather and climate, thus answering the question of why climate models can be reliable despite weather being changeable and chaotic. He also developed methods for identifying specific signals, fingerprints that both natural phenomena and human activities imprint in the climate. His methods have been used to prove that the increased temperature in the atmosphere is due to human emissions of carbon dioxide.

Around 1980, Giorgio Parisi discovered hidden patterns in disordered complex materials. His discoveries are among the most important contributions to the theory of complex systems. They make it possible to understand and describe many different and apparently entirely random materials and phenomena, not only in physics but also in other, very different areas, such as mathematics, biology, neuroscience and machine learning.
