    Nobel Prize in Physics for Trio for Research on Climate Change and Complex Systems

    An international trio of scientists shared the Nobel Prize in Physics on Tuesday to unveil a pioneering way to find order hidden in complexity and how human activity is changing the Earth’s climate. Lay the foundation for a computer model to explore.

    Half of the coveted award was awarded to Giorgio Parisi of the University of Sapienza in Rome, Italy, for discovering patterns of interaction between order and disorder on a molecular to planet-wide scale. According to the Royal Swedish Academy of Sciences, which announced its annual awards, his work allows us to explain seemingly random phenomena, from physics and neuroscience to machine learning.

    Dr. Parisi had his phone at hand when the Nobel Committee called at the beginning of Tuesday. “In a way, I didn’t expect it, but I knew there was a chance, so I put the phone near me,” he said. “I was very happy.”

    The other half of the award was shared by Princeton University senior meteorologist Syukuro Manabe and Klaus Hasselmann of the German Maxplank Meteorological Institute in Hamburg for their unique efforts to model the Earth’s climate. I did.

    Taken together, the award bestows theory and practice.

    Roberto Dyckgraf, a physicist who is the director of the Princeton Institute for Advanced Study, said: “It’s hard to think of something more complex than the world’s climate.”

    Dr. Manabe’s research dating back to the 1960s showed how increased levels of carbon dioxide lead to higher temperatures on the Earth’s surface, laying the foundation for the creation of climate models used today.

    “All areas of climate modeling have their roots in skiing,” said Gabriel Vecchi, deputy director of the Institute for Earth Systems Modeling Cooperatives at Princeton University. “The idea of ​​taking something as complex as a climate system, coding the equations that govern it, putting it into a computer, and using it to simulate a climate system began with him.”

    In the 1970s, Dr. Hasselman of Hamburg created a model to tie together. Weather and climate, Helps eliminate uncertainty about the reliability of climate models, despite unstable and inconsistent weather, the Academy said. His work, including how to identify the different effects of both human activity and natural phenomena on climate, was used to show how human carbon dioxide emissions can cause elevated temperatures. It has been.

    “I’m completely surprised … Bolt from Blue,” Dr. Hasselman said when he called Nobel officials. “I came to the climate as a physicist,” he said. “For those who aren’t actually working on climate change, it’s hard to realize that we’re actually doing it until it’s clear.”

    Most scientists have been united in recent years around the idea that greenhouse gas emissions from human activity, such as burning coal for electricity, have contributed to the warming climate even before the Industrial Revolution. The decision to honor Mr. Manabe and Mr. Hasselman, originally from Japan, was made less than a month before the UN Summit on Climate in Glasgow, Scotland.

    Gavin Schmitt, director of NASA’s Goddard Institute for Space Studies in New York, a major center for global climate modeling, said: “This is not the usual fare for the Nobel Prize Committee. The topic they should be aware of is noteworthy.”

    A total of 218 people have won physics awards since it was first awarded in 1901 due to breakthroughs in the field from black holes to gravitational waves. This is the third time that the Nobel Prize has been awarded for research related to the impact of human activity on the Earth’s climate. The award will be awarded a prize of SEK 10 million, worth approximately $ 1.15 million.

    1995, Paul J. Crutzen, Mario J. Molina, F. Sherwood Rowland shared the Nobel Prize in Chemistry for identifying how industrial chemicals damaged the Earth’s protected ozone layer. In 2007, the United Nations Intergovernmental Panel on Climate Change and former US Vice President Al Gore jointly received the Nobel Peace Prize for their efforts to bring climate change to the world’s attention.

    Sylvester James Gates, Jr., a physicist at Brown University and president of the American Physical Society, said: “This is a large-scale physics work done for all humankind.”
