The award Nobel of Chemistry Mario Molina stated at the University of Navarra that "solving climate change would cost only 1 or 2% of the world's GDP". With this low cost, in his opinion, measures such as "improving transport efficiency, increasing efficient buildings, replacing coal with natural gas, capturing and storing carbon, promoting nuclear, wind, solar and biofuels, as well as improving forestry practices" could be implemented.

Mario Molina, honoris causa at more than 40 universities, gave a master class at the auditorium of the Center for Applied Medical Research (CIMA ) on the occasion of the 1st Scientific Gala of Navarra SciencEkaitza, organized by Aditech and the Regional Government.

In his intevention he spoke about his research about the weakening of the ozone layer and the consequences for the planet. "Science does not speak of good or bad. The solution to climate change is a matter of values, of ethics, since we have a great responsibility to the next generations," he said.

Three myths about climate change

Professor Mario Molina listed the three myths that are being talked about today to justify climate change. Firstly, some experts claim that climate change is an exaggerated view of reality, however, "the vast majority of scientists working in this field assure that the problem is real and worrying". In this way, he explained that "more than 97% of scientists think so".

On the other hand, a second myth that has spread is that the consequences of this change will only be seen by future generations. However, this impact on the planet, in his opinion, is already being seen by current generations. "The climate is changing: droughts, fires, melting ice at the poles and very high temperatures," he said. Events that are a direct consequence of "the irresponsible use of the energy we use," he added.

The last myth that Mario Molina debunked in his exhibition was the non-existence of an alternative to fossil fuels since, as he explained, there are alternatives such as electric cars, wind or solar energy. "These alternatives are already affordable and, in fact, are competing in many markets," the professor assured. "We just have to commit to take a step and change the culture in which we live."

Mario Molina encouraged the attendees by saying that these damages are not irreversible. "The problem is global and, therefore, the solution must also be global. Countries must work together to bring forward pacts that help change." In this sense, he affirmed that the Montreal Pact is a clear example that things are changing and that "if this is fulfilled, change is possible".
