Japanese-born American Syukuro Manabe, German Klaus Hasselmann and Italian Giorgio Parisi won the 2021 Nobel Prize for Physics on Tuesday, October 5, for work that helps understand complex physical systems such as Earth’s changing climate.
In a decision hailed by the UN weather agency as a sign of a consensus forming around man-made global warming, one half of the 10-million Swedish crown ($1.15-million) prize goes in equal parts to Manabe, 90, and Hasselmann, 89, for modeling earth’s climate and reliably predicting global warming.
The other half goes to Parisi for discovering in the early 1980s “hidden rules” behind seemingly random movements and swirls in gases or liquids, which can also be applied to aspects of neuroscience, machine learning and starling flight formations.
“Syukuro Manabe and Klaus Hasselmann laid the foundation of our knowledge of the Earth’s climate and how humanity influences it,” the Swedish Academy of Sciences said in a statement. “Giorgio Parisi is rewarded for his revolutionary contributions to the theory of disordered materials and random processes.”
Hasselmann, who is at the Max Planck Institute for Meteorology in Hamburg, told Reuters from his home that he did not want to wake up from what he described as a beautiful dream.
“I am retired, you know, and have been a bit lazy lately. I am happy about the honor. The research continues,” he said.
The Academy said Manabe, who works at Princeton University in the United States, had laid the foundation in the 1960s for today’s understanding of Earth’s climate.
Hasselmann, it said, had developed models about 10 years later that became instrumental in proving that mankind’s carbon dioxide emissions cause rising temperatures in the atmosphere.
Parisi, who dialed into the media briefing announcing the winners, was asked for his message to world leaders due to meet for UN climate change talks in Glasgow, Scotland, from October 31.
“I think it is very urgent that we take real and very strong decisions and we move at a very strong pace,” said the 73-year-old laureate who works at Sapienza University of Rome.
Work on climate changes has been recognized by Nobel prizes before.
Former US Vice President Al Gore and the UN climate panel received the Peace Prize in 2007 for galvanizing international action against global warming, and William Nordhaus won one half of the 2018 Economics prize for integrating climate change into the Western economic growth model.
“Skeptics or deniers of scientific facts…are not so visible anymore and this climate science message has been heard,” World Meteorological Organization Secretary-General Petteri Taalas said of this year’s award.
Physics is the second Nobel to be awarded this week after Americans David Julius and Ardem Patapoutian won the prize for medicine on Monday, October 4, for the discovery of receptors in the skin that sense temperature and touch.
The Nobel prizes were created in the will of Swedish dynamite inventor and businessman Alfred Nobel and have been awarded since 1901 with only a handful of interruptions, primarily due to the two world wars.
As last year, there will be no banquet in Stockholm because of the COVID-19 pandemic. The laureates will receive their medals and diplomas in their home countries.
The physics prize announcement will be followed in coming days by the awards for chemistry, literature, peace and economics. – Rappler.com
