THE Nobel Prize for physics has been awarded to scientists from Japan, Germany and Italy. Syukuro Manabe, 90, and Klaus Hasselmann, 89, were cited for their work in “the physical modeling of Earth’s climate, quantifying variability and reliably predicting global warming”. The second half of the prize was awarded to Giorgio Parisi, 73, for “the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.” The panel said, Manabe and Hasselmann “laid the foundation of our knowledge of the Earth’s climate and how humanity influences it.
Starting in the 1960s, Manabe demonstrated how increases in the amount of carbon dioxide in the atmosphere would increase global temperatures, laying the foundations for current climate models. Parisi “built a deep physical and mathematical model” that made it possible to understand complex systems in fields as different as mathematics, biology, neuroscience and machine learning. After the announcement, Parisi said that “it’s very urgent that we take very strong decisions and move at a very strong pace” in tackling climate change.
