Three shared Nobel Prizes for Physics for work on climate change

The Royal Swedish Academy of Sciences announced Tuesday that the Nobel Prize in Physics goes to three scientists for their work in helping to understand complex physical systems, work that has proven valuable in measuring and predicting climate.

At the Stockholm news conference, Academy General Secretary Goran K. Hansen and a panel of Nobel jurors presented half of the physics prize to Tsukuro Manabe and Klaus Hasselmann for their efforts in physical modeling of Earth’s climate, quantifying variability, and reliably predicting global warming. “

Hanson said half of the prize has been awarded to Giorgio Paris “for his discovery of the interaction of disorder and fluctuations in physical systems from atomic to planetary scales”.

The panel said Manabe and Hasselman’s work “laid the foundation for our knowledge of Earth’s climate and how humanity affects it.”

Born in Japan and now a senior meteorologist at Princeton University, Manabe pioneered the study of how increased levels of carbon dioxide in the atmosphere lead to increased temperatures at Earth’s surface.

A professor of meteorology at the Max Planck Institute for Meteorology in Hamburg, Germany, Hasselmann created a model that ties weather and climate together, thus answering the question of whether climate models are reliable even if the weather is variable and chaotic. Why can be

and Paris, a physicist at the Sapienza University in Rome, during his career, discovered hidden patterns in disordered complex materials, leading to the understanding of many different and apparently completely random materials and phenomena in all fields of science and mathematics. It became possible to describe them.

The three scientists will share a cash prize of $1.1 million. The Nobel Prize for Medicine was presented on Monday, with prizes for chemistry, literature, peace and economics coming later this week and early next week.
