Nobel Prize Climate 2021

nobel climate prize 2021

Studying the climate involves great complexity and great responsibility. Therefore, the Nobel Prize for Climate 2021 to three scientists whose study in physics and climate has broken the charts. The Nobel Prize winners are Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi. These three scientists have managed to explain one of the most complex phenomena to understand in science.

In this article we are going to tell you everything you need to know about the 2021 Nobel Prize for Climate and its importance.

The phenomenon is so complex that it has been called complex physical systems. Its very name suggests the difficulty of its understanding. The effects can range from the atomic scales to the planetary scale and affect both the behavior of electrons common to the climate of the entire planet. Hence its importance.

On Tuesday, the Swedish Academy awarded him for his contribution to research and his impact on global warming, and awarded him the famous Nobel Prize in Physics. Three scientists, Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi, pioneers in complex systems research and other experts in climate impact, were announced as the winners of the 2021 edition.

The secretary of the Swedish Academy of Sciences, Göran Hansson, broke the news, noting that the award given to these researchers was for their innovative contributions to our understanding of complex physical systems. The award, as well as the medical, chemical and literary awards announced this week, will be presented at an awards ceremony in Stockholm on December 8.

According to the Swedish Academy, the 73-year-old Italian Giorgio Parisi won a special award for discovering "hidden patterns in messy and complex materials." His discovery is one of the most important contributions to the theory of complex systems.

Syukuro Manabe from Japan and Klaus Hasselmann from Germany won awards for their "fundamental" contributions to climate modeling. Manabe, 90, shows how increasing carbon dioxide content in the atmosphere causes the temperature of the Earth's surface to rise. This work laid the foundation for the development of current climate models. In the same way, Klauss Hasselmann, 89, pioneered the creation of a model that links meteorology and climate.

Complex systems

Complex systems on the atomic and planetary scales can share certain characteristics, such as chaos and disorder, and behavior appears to be dominated by chance.

Parisi made his first contribution to his research in physics by analyzing a metal alloy called glass.or rotating, in which iron atoms are randomly mixed in a lattice of copper atoms. Although there are only a few iron atoms, they change the magnetic properties of the material in exciting and disturbing ways.

Parisi, 73, discovered that hidden rules affect the seemingly random behavior of solid materials and found a way to describe them mathematically. His work applies not only to physics, but also to very different fields such as mathematics, biology, neuroscience, and machine learning (artificial intelligence).

The committee stated that the scientist's findings "Make it possible for people to understand and describe many different and apparently completely random materials and phenomena". The Swedish Academy now views rotating glass as the epitome of Earth's complex climate behavior and research conducted by Manab and Hasselmann years later. And it is difficult to predict the long-term behavior of complex physical systems, such as our planet's climate.

Manabe, who worked at Princeton University in the United States, led the development of physical climate models in the 1960s, leading to the conclusion that carbon dioxide emissions are warming the planet. Due to its messy pattern, the climate of our planet is considered a complex physical system. In the same vein, Hasselman used his research to answer the question of why climate models can be reliable, even though the climate is changeable and chaotic.

These computer models that can predict how the Earth will respond to greenhouse gas emissions are essential to our understanding of global warming.

As Professor John Wettlaufer of Yale University explained, the Italian physicist is "building from disorder and fluctuation of complex systems at the micro level," and Syukuro Manabe's work points to "obtain the components of a single process ”. And put them together to predict the behavior of a complex physical system. ”“ Although they distribute prizes between the climate part and the disorder part, they are in fact interrelated, ”he explained.

Importance of the 2021 Nobel Prize for Climate

One of the conclusions that the decision leaves, especially in the Manabe and Hasselman elections, is to draw people's attention to climate problems.

According to Wettlaufer, through the award, the Nobel Committee proposed "the duality between the study of the earth's climate (from millimeters to the size of the earth) and the work of Giorgio Parisi." Dr. Martin Juckes, head of research in atmospheric sciences The person and deputy director of the British Center for Environmental Data Analysis (CEDA) said that seeing scientists win the Nobel Prize in Physics for their work on climate is "good news ”.

"The complexity of the climate system, coupled with the threat of the climate crisis, continues to challenge climate scientists today," said.

As you can see, the climate crisis that we are facing in this century makes scientists put in an open state or to be able to find feasible solutions. Climate change threatens to change the world we know and many of our economic systems need the stability that we have in the climate today.

I hope that with this information you can learn more about the importance of the 2021 Nobel Prize for Climate and what its characteristics are.
