Physics Nobel rewards work on complex systems, like climate

 

Physics Nobel rewards work on climate change, other forces

The Nobel Prize for physics has been awarded to scientists from Japan, Germany and Italy. Syukuro Manabe and Klaus Hasselmann were cited for their work in "the physical modeling of Earth's climate, quantifying variability and reliably predicting global warming". The second 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."

Three scientists won the Nobel Prize in physics Tuesday for work that found order in seeming disorder, helping to explain and predict complex forces of nature, including expanding our understanding of climate change.

Syukuro Manabe, originally from Japan, and Klaus Hasselmann of Germany were cited for their work in developing forecast models of Earth's climate and "reliably predicting global warming." The second half of the prize went to Giorgio Parisi of Italy for explaining disorder in physical systems, ranging from those as small as the insides of atoms to the planet-sized.

Hasselmann told The Associated Press that he "would rather have no global warming and no Nobel Prize.''

Manabe said that figuring out the physics behind climate change was "1,000 times" easier than getting the world to do something about it. He said the intricacies of policy and society are far harder to fathom than the complexities of carbon dioxide interacting with the atmosphere, which then changes conditions in the ocean and on the land, which then alters the air again in a constant cycle.

He called climate change "a major crisis."

The prize comes less than four weeks before the start of high-level climate negotiations in Glasgow, Scotland, where world leaders will be asked to ramp up their commitments to curb global warming.
