Nobel Prize Conversations

“I had decided as a child if it was possible to become a scientist and to do scientific research for a living that’s what I wanted to do”

In this podcast episode, we meet physical chemist Mario Molina who spent his life working on climate research. He was awarded the Nobel Prize in 1995 for his investigations into how CFC gases damage the ozone layer. Molina dedicated his life to reducing their use and advocating for ways in which we can reduce our impact on the Earth. Molina speaks about his report ‘What We Know’, a paper which discussed what we know about climate change in an effort to inform the public and oppose those who deny climate change. He also speaks about his childhood and about how his interest in science was sparked. 

Listen as we take you back to this conversation with Molina, recorded in 2014 as part of the series ‘Nobel Prize talks’. The host of this podcast is nobelprize.org’s Adam Smith, joined by Clare Brilliant.

Clare Brilliant: Welcome to Nobel Prize Conversations and this encore presentation of our April 2014 talk with chemistry laureate Mario Molina. I’m Claire. Brilliant, and I’m here with our host Adam Smith. Hi, Adam. 

Adam Smith: Hi, Clare.

Brilliant: With 1995 chemistry laureate Mario Molina we wrap up our series of six classic podcasts.  

Smith: And hasn’t it been interesting to hear this variety of podcasts from the past? Some of them are completely timeless, but others seem to have aged considerably in 10 years. 

Brilliant: How is it to listen to yourself now 10 years later? 

Smith: Maybe I’m one of the more things that hasn’t aged so well over the 10 years. It’s strange because you think you’re the same, you don’t change, but actually when you listen to yourself and the questions you ask, you think, gosh, things are a bit different. It was a “the past is a different country”, as L.P. Hartley said in The Go-Between and it really can bring it home. 

Brilliant: When you spoke to Mario in 2014, he’d already been living with the prize for nearly 20 years, and he’d really embraced a role as a leader in communicating about climate change. In this episode, you spend quite a lot of time talking about a 2014 paper called ‘What We Know’, and then you and I actually had the privilege of meeting Mario when we attend an event with him in 2018. I was really struck by his positivity, despite some of the enormous challenges posed by climate change. 

Smith: He was extremely good at getting that optimism across in 2018, wasn’t he? I remember audiences had become more worried about climate change than they were back in 2014 when we recorded this. But they seemed to come out of his talks more optimistic than they were when they went in, which is an incredible achievement. 

Brilliant: He was talking about such a difficult, and I guess, to most people, scary subject, but somehow you came out with a message of hope and I think that does come across in this interview as well. Sadly, Mario Molina is no longer with us as he died in 2020, but do you think the messages from this podcast are still relevant today? 

Smith: The world doesn’t see many people like Mario Molina with such optimism and the engaging power to convince people to come together. I really think that for that reason, this podcast stands the test of time and deserves another listen. It’s really worth taking seriously what Mario Molina has to say. Let’s listen to this encore presentation, the last in our series with Mario Molina. 

MUSIC  

Mario Molina: Hello. 

Adam Smith: To start out so you have just released from the American Academy for the Advancement of Science, this new report called ‘What We Know’, which you have chaired. 

Molina: Right. 

Smith: This is another report on global warming, and there have been many reports on global warming of course. Can you tell me what’s the need for this new report? 

Molina: Yes, the purpose is not really to issue a new report, it’s to communicate with the public at large, particularly in the United States, in a more efficient way. We’re not seeking to bring the science up to date or anything like that. We’re just attempting to have a better communication strategy highlighting just a few steps, maybe three at most four. The report is just a background so that it’s documented where this comes from, but the main work to be done will be to somehow through the media and interviews just to stress briefly these three or four important points about climate change that we want the public to be aware of.  

Smith: So it’s clarifying the message.  

Molina: It is clarifying the message. We’re working with professional communicators, understanding that we scientists often do not communicate well. That’s the main purpose and difference from other reports. 

Smith: The choice of title is very emphasise then: what we know. It’s just trying to communicate in simple, straightforward language what is currently understood about global warming. Is that right? 

Molina: That’s right. 

Smith: Okay. What is currently understood? What’s the main message?  

Molina: The main message is that there is a very clear consensus among experts and we quote numbers like, more than 90-97% of climate change experts agree that climate change is taking place and it’s most likely of human origin. That’s the main message. Then a second message is that it’s already happening. It’s not just something for the end of the century. The third, perhaps what is the newer message if you want, is that we’re dealing with risks. We are not necessarily worried mostly about the most likely chain of events, but working with economists in particular, we reached the conclusion that the society should react based on the on risks, namely that there will be some abrupt changes with very important consequences for society at large or for many groups if you want that risks that are unacceptable. Even if they’re not very likely, if you have something of a 10 or 20% risk or more of real calamities to happen, that should be avoided. The science is rather uncertain about this, but this is based on scientific insights and these changes can indeed happen. Perhaps also the fourth important message is that we can deal with this, we can do something about this in contrast to ideas that have been spread out that, oh, this would be just incredibly expensive and we can’t stop in any way using fossil fuels. We believe that’s the wrong message. The message is that we can deal with the problem at the reasonable cost, certainly smaller than what it would cost to shoot some of these abrupt changes that take place. 

Smith: That’s a hopeful message to end with. 

Molina: That’s right. Yes. 

Smith: There’s a lot in there. If we start first of all with this idea of climate change is happening and it is most likely caused by human activity. A lot of people seem to get quite hung up on that most likely piece and say, well, maybe it’s something we are doing, or maybe it’s something we’re not doing. That seems to stop other action, the conversation can in a way stop there. Why do you think everybody’s got so excited by this question of whether or not it is truly anthropogenic? 

Molina: When we elaborate on this, we use metaphors. When you drive your car, you wear seat belts and have airbags and not because you have a certainty that you will crash. There are so many things along these lines that prompt society to act. If you have a tumour and your physician tells you, oh, there’s only 80% chance that it’s cancer, just don’t worry about it, go home. It doesn’t make any sense to require certainty, but we clarify that indeed science is a complex system, and we have a very conservative, if you want, group of scientists behind this report precisely to be able to document these statements. There have been lots of exaggerations and unclear statements precisely because they were aware about people misunderstanding the message and scientists are just not happy with making statements that are actually not correct. 

Smith: Yes. We are very used to dealing with uncertainty in our own lives. Yet on the climate change issue, as I say, there seems to be more scope for the discussion of the importance of that certainty. For instance, you have the well-publicised climate change sceptics who seem to hold a lot of public opinion, have a lot of public interest in them. People listen to them. That’s odd in a way. 

Molina: Yes. We, of course, we’re very much aware of that. That’s why we want to give out a clear message and as needed, explain it with metaphors. Let me give you an even a more striking example. Extreme events that we’re worried about but that’s bringing climate change closer to home for many people. The metaphor we use is in the US for baseball games, if it’s clear that at some point some of the best known players were taking some drugs, okay? There are many more home runs, but you can’t assign any particular home runs because somebody took some drugs. All you can say is that the likelihood of having home runs clearly increased. That’s what’s happening with extreme events. We can’t attribute any particular one to climate change. That’s even less certain if you want, but overall, the statistics is clear. The idea that you need certainty is that something we want to explain? There are so many other examples, that society makes all sorts of political decisions, there’s almost never certainty withheld issues as well. Why would one want to have certainty with something so clearly worrisome that it would be so much against society a reasonable way of acting to ignore these threats. 

Smith: Do you have an answer to the question of why that has become such an issue? Have you an understanding of what it is that is stopping people accepting the idea?  

Molina: Oh, yes. We know that there was a very well financed public media campaign from interest groups. We also know that there are some artisan issues. It has to do with politics issue became polarised, and it’s a worry with, particularly with the Republican party in the United States that at some point took extreme positions. But those extreme positions, they’re not questioning whether it’s slightly or not, they’re simply claiming that this is all a hoax and that it’s just because the scientists want more money and so on. That’s why, in this case, we also stress that this is the consensus of experts and also of well-established scientific groups, the national academies, professional societies. You have to claim that all of sciences corrupt, and that begins to be sort of crazy, even the enormous impact that science has had on our lives. There is a whole range of reasons behind scepticism. Perhaps we can address them all as needed. But the most worrisome one is just perhaps the one that said, oh, it’s uncertain that scientists do not agree. That’s why that’s the first message. Scientists do agree that it’s happening, it’s real, and they do agree that it’s a big risk. 

Smith: Yes.

Molina: That’s the point. I know it’s a challenge.  

Smith: You mentioned that this is directed particularly at the American public. Is this, and I guess American institutions as well, is this a particular problem do you think for America? Is the acceptance of the evidence harder in America than elsewhere? 

Molina: Yes. But this, of course, we no longer elaborate in these documents and so on, but what is clear in terms of assessing what needs to be done about these problems? It’s clear that one of the best solutions would be to have an international agreement that would put a price on emissions. By the way, just stepping back for a moment, we don’t prescribe with these reports or messages, they’re not prescriptive. They just say, let’s put it on the table and let society take it seriously, discuss what to do. But coming back to your question, it’s clear that the main bottleneck for this international agreement at the moment is US Congress, because they will certainly not stratify any international agreement dealing with climate change because of the official posture of the Republican party. Without their approval, you can’t ratify an international agreement. Their official posture is to deny climate change science. My reasoning is that it’s something equivalent to still living in the age of astrology. That’s unacceptable for any rational society. I hope this for this reasons, if we make the message clear we should be able to bring the rationality to the system. But that’s the reason why the United States is particularly worrisome. It’s international political arena. We certainly know that countries like China, India and so on are very important for these agreements as well. We have indications that they would be willing to move much further ahead in terms of this sort of international agreements than at least the United States at the moment. That’s the bottleneck in terms of coming with a real solution to the problem.

Smith: That anti-science stance in this case of the Republican party is a very peculiar thing. Because I suppose it’s partly vested interests causing one to have that policy but it’s also an antagonistic attitude to science itself. It’s been pointed out by others that the number of scientists within the political system is extremely small or perhaps even zero. On the face of it, it just seems ludicrous that one would have an antagonistic attitude towards the practice of science.  

Molina: Yes. That’s why there’s such a strong division, because in fact some Republicans tend to agree. It’s just that they are at the moment compelled to take the parking line. That’s beginning to change. There are beginning to be some very important divisions within the Republican party. Second point, we work with many Republicans that are not now in Congress, but were in government before, and many of them very much agree with our conclusions. In fact, many important decisions connected with the environmental problems and global environmental problems as well were carried up with Republican administrations. One point that we’re also bringing forth that appears to appeal to the public in the United States is we’ve done this before. The United States has been a leader in many environmental issues. One example is the stratospheric cause issue that I was involved with, and it’s one global problem has been solved very efficiently with leadership from the United States, from Republicans. It has happened before.  

Smith: Sorry to dwell on this question of why people find it hard to just accept that action is needed, but is it also the magnitude of the problem? People just feel completely overwhelmed by that?  

Molina: Sure. That’s why one of the important messages is that it’s a challenge, but we’re not suggesting solving on very expensive changes. This has been carefully analysed, again, by experts, economists, and we can certainly deal with it. It’s an enormous challenge, but it’s something that is striking that it’s not an enormous cost, because with creativity and with technologies for clean energies being further developed, we do have examples of things that are already happening that would bring us to a solution of this problem, or at least a clear indication of the right path. We don’t have to speculate that this is something that perhaps society could actually deal with. We can cite specific examples. 

Smith: Then I wanted to move on to this question of risk. You mentioned that there are the kind of the gradual changes that we are already observing, but you are pointing out that there are risks of truly catastrophic events ahead. Tell me more about those. 

Molina: One worry we had is for the scientific community to perceive this as alarm and so on. That’s why we don’t even use the word catastrophe in the document. It’s very carefully avoided, but it’s the equivalent, that you’ll have extremely damaging events. But the risk is based on science. We have indications of changes in climate in the past, and we have very clear indications that there’s more energy in the system now and so on. It is not sheer speculation. The existence of risk is based on science. We are very much aware that it’s one of those issues that is hard to communicate to the public, because they’re often very ill-informed about the nature of risks. This is where our work with professional communicators is also very helpful because they can measure and probe how do people react to all to these various sorts of statements and what’s the normal conception they have about risk? They don’t have a good quantification of risks. If it’s small or large, they often just get confused. We’re, again, perhaps through metaphors or examples, we can explain why is it very important for society to take some sort of insurance if you want. That’s one way to explain it to them for risks that are real, and that’s quite reasonable and accepted by people in general, it’s very quite acceptable to spend some resources on insurance because it has paid off clearly in the past. 

Smith: What’s an example of the sort of thing that we’re insuring against?  

Molina: Here we’re again very careful and we cite and quote some studies like a national academy story or some IPCC stories, they’re actually quite conservative here. But examples would be say the drying up of the Amazon forest or changes in the ocean circulation. Here a conclusion is the following: that one scientist begin to look very carefully at some of these specific possibilities, they turn out not to be very likely so the main worry remains surprises. That’s why we don’t want to give many very specific examples of things to worry about without the statement look. Once we identify this large releases of methane from permafrost, these are all feasible. Those do not seem very likely, but we have so much experience with surprises, even the extreme events. We’re not quite expected, and they are happening already. I realise it’s a difficult issue to communicate, but again, we want to be very honest and not put on the table issues or possibilities that have already been carefully examined. There are, on the other hand, issues such as the rising sea levels that are happening and happening faster than anticipated with very clear consequences that are already materialising. Once you have higher sea level, then if you have a bad weather or hurricane storms and coastal areas they become much more damaging, even if there’s just a relatively small increase in sea level. That’s one of the main worries if you want. 

Smith: I can see it’s a very difficult situation because if you elaborate specific risks and they don’t come to pass, then people on the other side of the fence will turn around and say that didn’t happen. You see, it’s all wrong. In a way, that’s the permanent problem. I suppose that you are trying to be very measured and precise in what you say, and the people who are arguing against you don’t have that limitation. They can just pull, if they want, anything out of the air and say, look, climate change scientists say that this is going to happen and it’s not happening, so it’s all wrong. Which obviously doesn’t hold up as an argument, but it’s good as a soundbite. 

Molina: That’s right. That’s why, first of all, in the end we make a strong case that the climate is indeed changing because sceptics, until perhaps very recently, were claiming that, oh, it’s actually the climate goes up and down and so on. That part is clear and that part there is consensus. But the second point, in some sense, we try to rely on the record and the honesty that is established or in many other areas of the experts, the scientific community and so on. If necessary, we can certainly have debates or do whatever is needed with people that think to be experts on the other side. For the public in general, we believe we don’t need to sort of do the signs, the complicated science in great detail. We just need to make the case that the science is clear about the risk. 

Smith: What do you hope the report will achieve? What do you hope will be the result? 

Molina: The result, we hope, is that the polls will begin to show a shift, which is happening already. We will push the shift in public opinion. It’s happening already because of extreme events that are people just until recently, where all this is just a worry for future generations. It doesn’t affect us at all, but there’s so many people already being affected that there is a change in perception. We believe if we, for the first time if you want, could organise a public relations campaign comparable to the one that was carried out. One the other side, we hope to have an impact on public opinion and subsequently on the perception of politicians about this, of course, because they count on public opinion often to support their decisions. We realise that it’s not something that’s going to happen immediately, but we believe that if a world carried out campaign can in fact move the results of the poll. 

MUSIC   

Smith: When you compare this problem to the one you worked on earlier on CFCs and reducing CFC emissions, was the same kind of publicity campaign required for that? Or was there just an easier acceptance? 

Molina: It was easier because energy is behind so many activities of society that’s clearly more difficult and behind economic road. We had an easier time with the CFCs, but fortunately we were able to act before it became polarised or politicised. We did not have this division along party lines materialising. We were able to act before that, and public opinion was important, but it was really the opinion of decision makers, leaders in government that were able to make things sufficiently important to reach an international agreement. We were not really counting there on public opinion driving the solution to the problem but it was certainly part of it. Whoever had looked at it and so on, it supported. There were of course sceptics as well. Another very important difference if you want, is that we were able to work with industry. At the beginning, they were sceptics, of course, but after the science became very clear the industrial sector collaborated with us. By the way, what’s happening now with climate change is not that the private sector is against it. It’s just some interest groups in the private sector are against it, but some others are in favour. That’s another thing we will try to take advantage of, that we can work with powerful groups that understand the problem. Not all the business minded people think that the problem is a hoax. But again, we clearly had an advantage with the stratospheric on issue in that at some point essentially all of industry was behind the solution to the problem. 

Smith: If you can help to achieve this ongoing change in the public opinion in the US, that’s part of the battle. Do you think that in the long term, the combination of a developed world already sort of at high levels of energy usage and an emerging world using more and more energy as time goes on, can reach a solution and in fact, act concertedly to prevent truly damaging global warming? 

Molina: Yes. That’s of course a very important question. We believe that it’s possible, but it will require further development in technology so that the options to use less fossil fuel become also more economically attractive. That’s happening. There is a clear tendency for clean energies to become cheaper. Two points here to make, one is we’re very much aware of the need of a good section of the global population that doesn’t have access to energy, and that’s a high priority also. But at the moment, at least for the near future, that would not be, even if they were to use fossil fuels or wood that would not detract from the main effort of the rest of the countries. We are very willing to promote access to energy for poor populations. Obviously, we’re not suggesting that there should be zero emissions. We’re just suggesting to do the most efficient way. By the way, these questions are no longer part of this report, we’re suggesting let’s put all of this on the table and have experts continue discussing that. The second point is that, yes, although there are still some problems ahead, we should put everything on the table. Carbon capture, for example, and storage is at the moment just too expensive but perhaps in the future it might be feasible. One of the more controversial possibilities, which we do not deal with in this particular report, is nuclear energy, because that has a very safe historical record in spite of Fukushima. We know that was a big problem in time, but it’s a form of energy that exists. The price keeps coming down, and it’s not that high according to the recent studies. It’s available. The hope is that we will, again, with time develop even safer technologies. But again, the point there with nuclear energy is that it’s the historical fact that it has worked with relatively little problem compared to fossil fuels and other forms. 

Smith: Yes. It’s, again, down to this perception of risk. 

Molina: That’s right. 

MUSIC 

Smith: You find yourself at the forefront of arguments about global climate. As a child, you were a very scientifically interested child, were you not? 

Molina: That’s right. Yes. 

Smith: What form did your scientific explorations take? 

Molina: When I was child, quite young, 10 years old or so, I was already quite interested. I like to read and read the biographies of scientists and so on, and then started to play with the chemistry sets, microscopes. I was fascinated with these games if you want. Then I just continued it. It was not something connected to school, but it was more connected to as a hobby. 

Smith: I like the use of the word games that. Was it the tools that you enjoyed? Was it the questions you enjoyed?  

Molina: It was probably the questions and doing experiments myself. I was lucky my father’s sister was a chemist, and after I showed a lot of interest in these things, she helped me do more sophisticated experiments. To me, that was just fascinating to actually see things with my own eyes and do the experiments with my own hands. It’s this active learning, which by the way, is a tendency nowadays to change education quite dramatically, to have kids do these sort of things rather than just memorising. This natural curiosity that we have as children, just looking through a microscope and suddenly discovering a new world there with all sorts of little creatures moving that you don’t see with your naked eyes. That sort of thing was fascinating to me. I had a number of good teachers that were sympathetic, if you want to, with this attitude towards science eventually this could materialise. I had decided as a child if it was possible to become a scientist and to do scientific research for a living that’s what I wanted to do. 

Smith: You had your aunt who was influencing you, and your parents were nurturing. They gave you the space you needed. 

Molina: My parents were nurturing. They were not scientists. My father was a lawyer, but they nurtured it. They supported my interest.  

Smith: Yes. Did you ever contemplate any other career? 

Molina: I did. As a kid, I liked music. I still like it a lot of course. I used to play the violin. I did contemplate, well, maybe that’s an option. I could become a musician. Somehow my parents got some advice that unless I was willing to spend eight or 10 hours a day just playing the violin that I should just give it up. To me, that was very bad advice because you could of course, get very involved in music without being a musician. Fortunately, even though I gave up eventually playing the violin myself, I never gave up my fondness for music. But if I had a chance again, I would not give it up. I would just do it as a hobby. I think that was just because I did not get the correct advice. Fortunately, that didn’t affect at least learning and listening to music. 

MUSIC  

Smith: That’s true. You were brought up in Mexico, but also traveling around? 

Molina: Yes, actually as a child, because of this interest I had in the sciences, my parents sent me to Switzerland for a couple of years to learn German.  

Smith: How old were you? 

Molina: I was probably 11. 

Smith: Gosh. Yes.  

Molina: This was to just boarding school. It was a very good experience because my chemistry teacher in Switzerland was somebody I got along very well with and did experiments. The disappointment I had, which fortunately was not seriously, I thought now that I’m going to Europe, all my friends will also be like me and they will like science a lot. They were just like my Mexican friends. Of course, I had normal friends and played and did things, but my friends at that age did not like anything connected to school. In Europe, it was something I did on my own or with my teachers, not with my friends. That happened much later. Eventually just in college, or actually when I start the college and the PhD, that’s when you begin to, of course, share all these interesting times with your colleagues. As a child, it was very much a lonely activity because again of the normal situation that I hope is changing now of children just disliking school and disliking science because it’s just memorising all sorts of facts and very boring. 

Smith: Yes. The opposite of what it is really.  

Molina: Exactly. Yes. 

Smith: That does indicate you were quite a precocious child then, that you were so turned onto science by the age of 11 that you were sent to a school to nurture those interests. That’s unusual. 

Molina: My parents had sort of tradition they wanted to us and my brothers and sisters abroad as young kids to learn a lot, another language and to be exposed to another culture. I was very lucky to be part of that. But in my case, of course, very much along the lines, as you just mentioned of, of pursuing my interest in science.  

Smith: You obviously feel very tied to Mexico, and now you divide your time between United States and Mexico. 

Molina: That’s right. 

Smith: Is that a hard balance to manage? 

Molina: It’s, but for many years, again, when I was, for example, just at MIT a researcher, then I went to Mexico just for vacations and so on. But at some point I started to do some work with my MIT colleagues that was connected with air quality in Mexico City, because we wanted to do something very interdisciplinary, not just involving science, but also policy economics and so on. That was remarkably successful because we got our students very interested in this interdisciplinary approach to social problems. Making sure that their basic interest in whatever field they were working remained very strong. But as a consequence of that, I realised I could at some stage that I was going to have more impact or that it was something more satisfactory to go back to Mexico to really do some work in my country of origin. I am born a Mexican and an American citizen, and I remain, of course, very much involved with my activities in the United States. The main example, perhaps been on this scientific advisory board to President Obama. I think fortunately what these issues I work with, they are very much international in scope. It’s both to Mexico and the United States interest to have this international perspective. That’s what brings it all together. Take this climate change approach, even though we’re focusing it to begin with in the United States, it’s something we can expand to Mexico and Latin Americans as well. But in Mexico, it’s really a change in field from science to science policy. The big challenge is how can we change not just regulations, but how can we actually affect the way society functions? It’s a big challenge, but we’ve been able to manage in some cases, like improving air quality in Mexico City and so on. It’s a challenge indeed. 

Smith: Is it a model you can export to other cities the successful way you’ve tackled it in Mexico City? 

Molina: Yes. In fact, we work closely with all the cities. Beginning with Latin America, we have some projects where we were simultaneously working also with Bogota and Santiago in Chile and Sao Paolo in Brazil. We have a lot to learn from each other. But again, there are other examples, other cities, not just in Latin America. That’s beginning to happen. There’s a lot of effort. There are associations of cities now, for example, dealing with a climate change issue, but in broader terms, in just in terms of improving the quality of life, greener cities where transportation works efficiently and so on and so forth. So this is an international effort that I think is beginning to take that form and becoming stronger and stronger learning from each other what works.  

Smith: The collaborative approach that sort of powers science that expanded to encompass everybody. 

Molina: That’s right. It’s a challenge because you have to deal with society that is hard to change, but if you find the right leaders, then we think it can be moved.  

Smith: It seems to me that in many ways you have transitioned really talking the word leader from being a practicing scientist to almost a sort of scientific leader. Do you miss the actual science, or are you so busy leading that you don’t miss it, you don’t have time? 

Molina: I do miss it. I was very much involved very early on doing experiments myself, but then later when having a large group, the experiments were actually carried out by my students. But now the way I looked at it is the even though I missed, if you want being heavily involved in just fundamental science or even applied science, but with a group of students, many of my former students are doing excellent science now as faculties in very well-known universities and so on. In some sense, I feel that I was able to keep that going, and I can do something that has more impact, a larger challenge to this translation of science into policy, which relatively few scientists successfully can do. It’s something we have to educate our students more and more about. That’s one component is this policy aspect. The other one is educational. Just making sure that the educational system keeps evolving and changing to become more and more effective. 

Smith: It is a very important point on both counts. I suppose as we were saying earlier, the idea that there is so little science in the political system just argues that there needs to be a greater cohort of scientists who want to be involved in politics. 

Molina: That’s right. 

Smith: And policy. Sure. 

Molina: I agree. Yes. 

Smith: Last question. Do you yourself think that at some point you might actually enter politics full time? 

Molina: No. I had that option some time ago. Already because having a Nobel Prize gives you all sorts of opportunities if you want. A few of my colleagues have done that. But no, I decided that was not the way I could function best. I could probably have more impact to things in a more important fashion, remaining outside politics but stressing disconnection between science and policy. It’s a different world if you really become a Secretary of Energy or whatever.

Molina: I’m pleased to do that. Sure.  

Smith: Okay. Thanks. Bye.
