The 2021 Nobel Prize in Physics rewards the prediction for global warming

Nobel Committee

The 2021 Nobel Prize in Physics was awarded to Ciugro Manabe, Glas Hasselmann and Giorgio Parisi.

Science – The Nobel Prize in Physics 2021 was awarded to Ciugro Manabe, Klaus Hasselmann and Giorgio Parisi for their “contribution to the understanding of complex body systems”, the Nobel Committee announced on Tuesday (October 5). After the winners Roger Benrose, Reinhard Jensel and Andrea Guess, Nobel Prize in Physics 2020 For their discoveries in black holes.

The American Ciuro Manabe and the German Glass Hasselmann were specially awarded for their analysis of the Earth’s climate, magnitude variation, and reliable prediction of global warming. The other half of the prize, the Italian Giorgio Parisi, was recognized for his work aimed at understanding “how disorder and fluctuations relate from atomic measurements to planetary measurements”.

Previous day, Monday, October 4, Nobel Prize in Medicine The work of feeling heat and pressure was rewarded. After medicine and physics, this will be a turning point Nobel Prize From Chemistry Delivered on Wednesday, October 6th. Literature will continue on Thursday Nobel Prize Peace Friday. The Bank of Sweden Prize, in memory of Alfred Nobel, was created in 1968 to mark the centenary of the company, ending the season on Monday 11th.

Detection of hidden objects in complex systems

Often, the Nobel Prize in Physics is awarded equally between two fundamental discoveries. They have one thing in common: understanding complex systems and finding meaning in them.

Thanks to the chiuro manabe, there is more CO2 in the atmosphere, increasing the temperature of the earth, Remember Nobel Committee. His work in the 1960s was based on climate models, which helped the IPCC raise awareness of climate emergencies.

10 years later, Klaus Hazelman developed a model. It makes the connection between weather and climate. This made it possible to respond to a classic climatoseptic critique: if we can not predict the weather for a few weeks, how can we believe that we can predict the evolution of the climate over decades?

The German researcher found very specific signals showing that the climate is affected by natural phenomena and human activities. This was later supported by other researchers, calculations and models, and that in recent decades the rise in temperature has not actually been caused by humans but by natural causes.

The 2013 IPCC report concludes on the basis of one of Klaus Hazelman’s corporate articles, “Human influence may be a major factor in global warming in the latter half of the year. The twentieth century”. Accurate Nobel Committee.

Spiral glasses

The other half of the Nobel Prize went to Giorgio Parisi. The Italian researcher “discovered hidden patterns in complex irregular objects”, the Nobel team notes. “His discoveries are one of the most important contributions to the theory of complex systems.

His work is about complex systems, so it is very difficult to summarize. Giorgio Parisi worked on alloys called “spin glass” which had amazing magnetic properties. According to Giorgio Paris, reading these spinning glasses is like reading Shakespeare’s tragedy, in which the atoms are characters with intricate relationships of hate and love. Giorgio Parisi invented a trick to better understand these amazing alloys, a system, a hidden method.
