The winners of this year's Nobel Prize in physics include Japan-born scientist Syukuro Manabe.
The Royal Swedish Academy of Sciences recognized three laureates whose scientific breakthroughs laid the foundation for a better understanding of climate and how humanity influences it.
The academy announced that one half of the prize jointly goes to Manabe and Klaus Hasselmann for the physical modeling of Earth's climate, quantifying variability and reliably predicting global warming.
The other half goes to Giorgio Parisi for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.
Manabe and Hasselmann both studied the Earth's changing climate. It's the first time the Nobel in Physics has recognized work in this area.
Manabe, who is 90-years old, said winning the honor was a "big surprise."
He completed his doctorate at the University of Tokyo, before moving to the United States. He is currently a senior meteorologist at Princeton University in New Jersey.
He worked at the National Oceanic and Atmospheric Administration. In the 1960s, he succeeded in demonstrating how carbon dioxide in the atmosphere contributes to an increase in temperatures at the Earth's surface.
Hasselmann built on that work. His modeling showed the link between weather and climate, and he also developed methods to identify the imprint of human activities in the climate. This allowed scientists to prove that human-created emissions can increase temperatures.
Together, their discoveries allowed for more reliable predictions of global warming.
Another scientist, Giorgio Parisi, had a more abstract impact on physics. He identified hidden patterns in complex systems. This has helped scientists from various disciplines better understand seemingly random phenomena.
At the announcement, Parisi said climate change must be tackled at a faster pace and urged immediate action.
Following the announcement, Manabe spoke to a crowd at Princeton University about the award and his career.
He said that, when he started his research, he could not imagine the consequences.
The scientist said climate change has become interwoven with problems related to energy, agriculture, and water, adding that trying to understand it is not easy.
Manabe also said arguments over global warming are "bewildering."
