Giorgio Parisi: Ordering chaos

Is there an order to chaos? Professor Giorgio Parisi walks us through the amazing patterns and rules that govern apparently random phenomena in his Nobel lecture on the theory of complex systems and their implications for our understanding of the world that surrounds us.

On December 8, 2021, Dr. Parisi was given the shared award for his discoveries “about how apparently random phenomena are governed by hidden rules.His work, which took place in the 1980s, was described by the Nobel prize committee as “among the most important contributions” to the theory of complex systems, helping physicists understand apparently random materials, with wide-ranging applications including mathematics, biology and machine learning.

The research conducted by Parisi and his collaborators in the early 1980s helped establish a framework that has been used to make sense of Earth’s climate. For example, the meteorologists who share the Nobel prize with Professor Parisi relied upon breakthroughs in theoretical physics made possible by his work to produce their models which reliably demonstrate global warming.


When accepting the Nobel prize, Parisi also expressed his desire that governments look at scientific evidence, and more specifically fundamental and applied science when engaging in decision making.

“I think the award is important not only for me but also for the other two because climate change is a huge threat to humanity and it is extremely important that governments act resolutely as quickly as possible,” Parisi told a press conference at the Lincean Academy in Rome.



Building Momentum for Climate Action

Countries are still coming together to discuss climate action notwithstanding delays to climate negotiations. Green recovery packages emerge as a top priority with policymakers signaling them as a key instrument with which to both kickstart the economy and avoid environmental breakdown. From the Land of the Rising Sun comes a wake-up call and a set of new initiatives to facilitate international dialogue and build momentum for climate action.


2021: A Year of New Opportunities

The return of science as a major player in decision making processes, a new US administration that values climate action and a shift in public and private perceptions of climate change. 2021 could be a breakwater moment for planetary wellbeing.


Clean Energy for All Europeans: EU Parliament adopted a new regulatory framework

New rules on renewables, energy efficiency and the governance of the Energy Union have been signed off by the European Parliament – an important step in enabling the European Union and its Member States to embrace the clean energy transition, follow up on the already adopted 2030 climate legislation and meet the Paris Agreement.
