For Mario Molina, 1995 Chemistry Nobel Prize, climate change should be analysed from the complex sciences to face its challenges. “Climate is a complex system, one of the most urgent [to solve]”, he mentioned at the opening ceremony of the Conference on Complex Systems, that is being held in Cancun this week.
Is evident for all that the frequency of extreme climate events all around the world has increased in the last years. The ice drop in Antarctica or the great devastation provoked by hurricanes Harvey and Irma are some examples of this (…) We cannot say climate change is the cause if these extreme weather events but there is strong evidence that there is a relationship between them," said the Mexican Nobel laureate.
For him, it is not possible to take seriously those who are against the scientific consensus about the human responsibility of these impacts on climate. “Many of the people that say we should not worry about climate change are not climate scientists (…) they have no idea”, he added.
Molina explained that if we want to understand the change in climate, atmosphere and the energy emanated from the Sun must be studied. Atmosphere has an important role because it reflects 30% of the infrared rays that come from the Sun due to the specific proportion of its components. It is then concluded that any change in it will change climate on Earth.
One of the major obstacles to climate change is to put science in sync with politics. To do this, he said, we must communicate the science of climate change to society. "Scientists are not trained to do it”, he said. That's why "we have to implement an interdisciplinary model [to facilitate this dialogue with society]. "
Finally, for Molina this theme goes beyond the science itself. "We are not talking about science, we are talking about ethical values in ensuring a better place for future generations," he concluded.
