The three laureates share this year’s Nobel Prize in Physics for their studies of chaotic and apparently random phenomena. Syukuro Manabe and Klaus Hasselmann laid the foundation of our knowledge of the Earth’s climate and how humanity influences it.

Giorgio Parisi is rewarded for his revolutionary contributions to the theory of disordered materials and random processes.

Complex systems are characterised by randomness and disorder and are difficult to understand. This year’s prize recognises new methods for describing them and predicting their long-term behaviour.

One complex system of vital importance to humankind is Earth’s climate. Syukuro Manabe demonstrated how increased levels of carbon dioxide in the atmosphere lead to increased temperatures at the surface of the Earth.

In the 1960s, he led the development of physical models of the Earth’s climate and was the first person to explore the interaction between radiation balance and the vertical transport of air masses. His work laid the foundation for the development of current climate models.

About ten years later, Klaus Hasselmann created a model that links together weather and climate, thus answering the question of why climate models can be reliable despite weather being changeable and chaotic.

He also developed methods for identifying specific signals, fingerprints, that both natural phenomena and human activities imprint in the climate.

@thePiggsBoson Was waiting for this thread. Thanks! And is there a way to read about the research work of these scientists in detail?

@thePiggsBoson Order existence in disorder That is how planet earth is running!!! We realise climate change effects us but act when it effects badly like Corona virus is created and starts killing people. One way my premonition came true!!!Thanks to Alfred Nobel. Ref.Nobel Prize physics 2021

@thePiggsBoson As compared to seemingly random natural events, human activities have probably a lesser effect on climate, but in any case a significant effect.

@thePiggsBoson About Giorgio Parisi's work, is it related somehow with entropy?

@thePiggsBoson Ecco il Pippone sul claimat cieing.

@thePiggsBoson Is there a brief list of "reliable climate predictions" these guys made and it's accuracy when compared to actual observations?.

@thePiggsBoson Thank you for this thread!

@thePiggsBoson These three people are portrayed as very handsome:)
