Climate Scientists Win Nobel Prize In Physics

Syukuro Manabe, Klaus Hasselmann, Giorgio Parisi win 2021 Nobel Prize in Physics for exposing humanity's increasing role in the global climate change.

In 2020, mathematician Roger Penrose was bestowed upon the most prestigious honor in science along with Andrea Ghez, who became only the fourth woman laureate in physics and Reinhard Genzel of the Max Planck Institute, for furthering our understanding of the black holes.

This year, the Nobel Prize foundation has again elected three joint winners. One half of the Nobel prize to climate scientists Syukuro Manabe of U.S.A and Klaus Hasselmann of Germany and the other half to Italian physicist Georgio Parisi.

We have all read about the global warming in our school textbooks, that humans are influencing the climate and the earth's temperature by burning fossil fuels. But how did the scientific community arrive at that conclusion in the first place?

The answer is, works of notable scientists like Syukuro Manabe, who is a senior meteorologist at the Princeton University, have helped establish humanity's increasing role in much of everything that is gone wrong with this planet.

Starting in the 1960s, Manabe pioneered the use of computers to simulate climate change. He demonstrated in 1970 that increase in the amount of carbon dioxide levels will rise global temperatures by 0.57°C by 2000. He was spot on as the earth had warmed by 0.54°C.

Klaus Hasselmann, leading oceanographer in Germany and the then director of the Max-Planck-Institute of Meteorology, also arrived at the same conclusion. He showed that despite short term weather fluctuations, climate models are reliable in long term.

Their studies further revealed that the global temperature is projected to increase by an additional 2°C – 3°C during the 21st century. So, we may take climate change lightly today but in the future its dangers will be observable in day to day life as the scientists have warned.

The third winner is Geogio Parisi whose research areas include statistical mechanics and complex systems. He has developed a mathematical model in order to understand complex systems such as the earth's global climate, the human brain and ultimately the entire universe.

Did you know that total 115 Nobel prizes in physics have been awarded since 1901? The winners this year include some of the oldest awardees. Manabe and Hasselmann are 90 and 89 respectively, while Parisi is relatively younger at 73 years.

Their recognition by the Nobel Prize committee shows that our knowledge about the climate change is built upon strong scientific foundations. Thus, no matter how much the politicians, the industrialists or the others deny climate change, it is happening at every moment.

After the announcement, Giorgio Parisi said in relation to climate change: “It is very urgent that we take strong decisions and move at a very strong pace. It is clear for future generations that we have to act now to tackle the climate change."
