Three scientists have won the Nobel Prize in physics for contributions to the understanding of "complex physical systems" such as the Earth's climate.
The scientists discoveries "demonstrate that our knowledge about the climate rests on a solid scientific foundation," Thors Hans Hansson, chair of the Nobel Committee for Physics, said in a statement by the Royal Swedish Academy of Sciences announcing the winners.
Syukuro Manabe and Klaus Hasselmann were awarded jointly for the physical modelling of the Earth's climate, "quantifying variability and reliably predicting global warming."
Manabe, a senior meteorologist at Princeton University, demonstrated how increased levels of carbon dioxide in the atmosphere lead to increased temperatures.
His work in the 1960s led the development of physical models of the Earth's climate, and his worklaid the foundation for the development of current climate models.
Around a decade later, Hasselmann, a researcher inclimate dynamics and professor emeritus at the Max Planck Institute for Meteorology in Germany, created a model that links weather and climate — answering the question of why climate models can be reliable despite weather being changeable and chaotic.
The other half of the prize was awarded to Giorgio Parisi "for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales."
Parisi, a professor in theoretical physics at Sapienza University in Rome, discovered hidden patterns in disordered complex materials. His discoveries have made it possible to understand phenomena in areas such as physics, biology and neuroscience.
After the announcement Parisi was asked if he had a message ahead of the COP-26 climate change conference in Britain beginning on Oct. 31. He said it was "very urgent that we take very strong decisions and move [at] a very strong pace” in tackling climate change.
“It’s clear for the future generation we have to act now in a very fast way,” he said.
