2021 Nobel Prize: Prizes for Manabe, Haselman and Parsi in Physics

The 2021 Nobel Prize in Physics has been awarded jointly to Manabe, Haselman and Parisi. The award has been given to scientists from Japan, Germany and Italy.

New Delhi. The Nobel Prize in Physics was awarded on Tuesday after the world’s prestigious Nobel Prize was announced on Monday. The award has been given to scientists from Japan, Germany and Italy. Soukuro Manabe, 90, and Klaus Hasselmann, 89, have been awarded for their work in “physical modeling of Earth’s climate, quantifying variability, and reliable prediction of global warming”.

While the second part of the prize has been given to 73-year-old Giorgio Parisi for his “discovery of the interaction of disorder and fluctuations in physical systems from atomic to planetary scales”. The Nobel Prize panel said that Manabe and Hasselman “laid the foundation for our knowledge of the Earth’s climate and how humanity affects it.”

In the early 1960s, Manabe demonstrated how increasing the amount of carbon dioxide in the atmosphere would increase global temperatures, laying the foundation for current climate models. Nearly a decade later, Hasselman created a model that links weather and climate, and helps explain why climate models can be reliable, despite the chaotic-looking nature of the weather.

They also developed ways to look for specific signs of human impact on the climate. Parisi “created a profound physical and mathematical model” that made it possible to understand complex systems in fields such as mathematics, biology, neuroscience, and machine learning.

After the Nobel Prize was announced, Parisi said, “To tackle climate change it is very important that we make very strong decisions and move very fast. It is clear to future generations that we have to act now.” “

The winners were announced on Tuesday by Goran Hansson, Secretary-General of the Royal Swedish Academy of Sciences. It is common for many scientists working in related fields to share the award.

The prestigious award carries a gold medal and 10 million Swedish kronor, or approximately US$1.14 million. Its prize money comes from a will left by Swedish inventor Alfred Nobel, the creator of the prize, who died in 1895.

Earlier on Monday, the Nobel Committee awarded the Prize in Physiology or Medicine to Americans David Julius and Ardem Patpoutian for their discoveries. Now in the coming days, awards will also be given for outstanding work in the field of chemistry, literature, peace and economics.
