      Elsa Olivetti appointed associate dean of engineering

      by

      Elsa Olivetti, the Jerry McAfee (1940) Professor in Engineering in the Department of Materials Science and Engineering, has been appointed as associate dean of engineering, effective Sept. 1.

      As associate dean, Olivetti will oversee a number of strategically important programs and initiatives across MIT’s School of Engineering. She will help lead and shape school-wide efforts related to climate and sustainability. In close collaboration with Nandi Bynoe, the assistant dean for diversity, equity, and inclusion; the school’s DEI faculty lead; and various program faculty leads, Olivetti will oversee the school’s DEI activities and programs. She will also assist with the faculty promotion process and will support both faculty and students across the school with regards fellowships, awards, and honors.

      “Professor Olivetti has demonstrated tremendous leadership abilities, particularly as co-director of the MIT Climate and Sustainability Consortium. Her contributions as a researcher, educator, and leader at MIT have been substantial,” says Anantha Chandrakasan, dean of the School of Engineering and the Vannevar Bush Professor of Electrical Engineering and Computer Science. “I am thrilled to welcome her to the School of Engineering leadership team and look forward to closely with her in this new role.”

      Olivetti first joined MIT as a graduate student after receiving her bachelor’s degree in engineering science from the University of Virginia. As a PhD student in the Department of Materials Science and Engineering (DMSE), her research focused on electrochemistry in inorganic materials for use in lithium-ion batteries. Through postdoctoral research and a staff scientist position with the MIT Materials System Laboratory beginning in 2009, Olivetti developed methods for streamlined carbon footprinting of electronics, a method that is still used widely by the electronics industry.

      In 2014, Olivetti joined the DMSE faculty, where her team works in sustainable and scalable design, processing, and manufacturing of materials use across industries. The Olivetti Group develops experimental and analytical methods for efficient use of industrial waste and recycled materials in concrete, metals, and plastic guiding decisions on a plant floor to policy makers.

      Olivetti’s team has also developed methods to automatically learn from texts within materials ranging from inorganic materials synthesis, zeolites, solid state batteries, and cement. Her work uses an interdisciplinary approach combining industrial ecology with materials science and engineering to inform and then mitigate the environmental and economic impact of materials.

      Olivetti has lead climate and sustainability efforts across the Institute. She serves as the co-director of the MIT Climate and Sustainability Consortium (MCSC). Launched in 2021, the MCSC fosters collaboration between academia and industry in an effort to accelerate real-world solutions for the climate crisis at scale. Under Olivetti’s leadership alongside co-director Jeffrey Grossman, the Morton and Claire Goulder and Family Professor in Environmental Systems, and executive director Jeremy Gregory, the consortium has grown to 18 member companies and has provided 20 research projects with seed funding. It has also launched programs such as the MCSC Climate and Sustainability Scholars Program for undergraduate students and the MCSC Impact Fellows Program for postdocs.

      In addition to her leadership at the MCSC, Olivetti is a member of the MIT Climate Nucleus, a faculty committee responsible for the implementation of “Fast Forward: MIT’s Climate Action Plan for the Decade.”

      A dedicated educator, Olivetti has made significant contributions to MIT’s material science and engineering education. She was instrumental in the development of a refined DMSE undergraduate curriculum. She also launched a new class 3.081 (Industrial Ecology of Materials) and served as a founding thread lead for MIT New Engineering Education Transformation’s Advanced Materials Machines program. Olivetti launched “Course 3 Industry Seminars,” which provide undergraduate students an opportunity to learn from industry leaders in fields like manufacturing and environmental consulting.

      Throughout her career, Olivetti has received numerous awards and honors for both her commitment to students and her research contributions. She is the recipient of the 2017 Earll M. Murman Award for Excellence in Undergraduate Advising, a 2020 Paul Gray Award for Public Service, the 2021 Bose Teaching Award, 2021 MacVicar Faculty Fellowship, and the 2023 Capers (1976) and Marion McDonald Award for Excellence in Mentoring and Advising. She also received an Early Career Faculty Fellowship from the Minerals, Metals and Materials Society as well as a National Science Foundation Early Career Development Award.

      Olivetti joins Dean Chandrakasan and Deputy Dean Maria Yang, the Gail E. Kendall (1978) Professor, on the School of Engineering faculty leadership team. More

      3 Questions: How are cities managing record-setting temperatures?

      by

      July 2023 was the hottest month globally since humans began keeping records. People all over the U.S. experienced punishingly high temperatures this summer. In Phoenix, there were a record-setting 31 consecutive days with a high temperature of 110 degrees Fahrenheit or more. July was the hottest month on record in Miami. A scan of high temperatures around the country often yielded some startlingly high numbers: Dallas, 110 F; Reno, 108 F; Salt Lake City, 106 F; Portland, 105 F.

      Climate change is a global and national crisis that cannot be solved by city governments alone, but cities suffering from it can try to enact new policies reducing emissions and adapting its effects. MIT’s David Hsu, an associate professor of urban and environmental planning, is an expert on metropolitan and regional climate policy. In one 2017 paper, Hsu and some colleagues estimated how 11 major U.S. cities could best reduce their carbon dioxide emissions, through energy-efficient home construction and retrofitting, improvements in vehicle gas mileage, more housing density, robust transit systems, and more. As we near the end of this historically hot summer, MIT News talked to Hsu about what cities are now doing in response to record heat, and the possibilities for new policy measures.

      Q: We’ve had record-setting temperatures in many cities across the U.S. this summer. Dealing with climate change certainly isn’t just the responsibility of those cities, but what have they been doing to make a difference, to the extent they can?

      A: I think this is a very top-of-mind question because even 10 or 15 years ago, we talked about adapting to a changed climate future, which seemed further off. But literally every week this summer we can refer to [dramatic] things that are already happening, clearly linked to climate change, and are going to get worse. We had wildfire smoke in the Northeast and throughout the Eastern Seaboard in June, this tragic wildfire in Hawaii that led to more deaths than any other wildfire in the U.S., [plus record high temperatures]. A lot of city leaders face climate challenges they thought were maybe 20 or 30 years in the future, and didn’t expect to see happen with this severity and intensity.

      One thing you’re seeing is changes in governance. A lot of cities have recently appointed a chief heat officer. Miami and Phoenix have them now, and this is someone responsible for coordinating response to heat waves, which turn out to be one of the biggest killers among climatological effects. There is an increasing realization not only among local governments, but insurance companies and the building industry, that flooding is going to affect many places. We have already seen flooding in the seaport area in Boston, the most recently built part of our city. In some sense just the realization among local governments, insurers, building owners, and residents, that some risks are here and now, already is changing how people think about those risks.

      Q: To what extent does a city being active about climate change at least signal to everyone, at the state or national level, that we have to do more? At the same time, some states are reacting against cities that are trying to institute climate initiatives and trying to prevent clean energy advances. What is possible at this point?

      A: We have this very large, heterogeneous and polarized country, and we have differences between states and within states in how they’re approaching climate change. You’ve got some cities trying to enact things like natural gas bans, or trying to limit greenhouse gas emissions, with some state governments trying to preempt them entirely. I think cities have a role in showing leadership. But one thing I harp on, having worked in city government myself, is that sometimes in cities we can be complacent. While we pride ourselves on being centers of innovation and less per-capita emissions — we’re using less than rural areas, and you’ll see people celebrating New York City as the greenest in the world — cities are responsible for consumption that produces a majority of emissions in most countries. If we’re going to decarbonize society, we have to get to zero altogether, and that requires cities to act much more aggressively.

      There is not only a pessimistic narrative. With the Inflation Reduction Act, which is rapidly accelerating the production of renewable energy, you see many of those subsidies going to build new manufacturing in red states. There’s a possibility people will see there are plenty of better paying, less dangerous jobs in [clean energy]. People don’t like monopolies wherever they live, so even places people consider fairly conservative would like local control [of energy], and that might mean greener jobs and lower prices. Yes, there is a doomscrolling loop of thinking polarization is insurmountable, but I feel surprisingly optimistic sometimes.

      Large parts of the Midwest, even in places people think of as being more conservative, have chosen to build a lot of wind energy, partly because it’s profitable. Historically, some farmers were self-reliant and had wind power before the electrical grid came. Even now in some places where people don’t want to address climate change, they’re more than happy to have wind power.

      Q: You’ve published work on which cities can pursue which policies to reduce emissions the most: better housing construction, more transit, more fuel-efficient vehicles, possibly higher housing density, and more. The exact recipe varies from place to place. But what are the common threads people can think about?

      A: It’s important to think about what the status quo is, and what we should be preparing for. The status quo simply doesn’t serve large parts of the population right now. Heat risk, flooding, and wildfires all disproportionately affect populations that are already vulnerable. If you’re elderly, or lack access to mobility, information, or warnings, you probably have a lower risk of surviving a wildfire. Many people do not have high-quality housing, and may be more exposed to heat or smoke. We know the climate has already changed, and is going to change more, but we have failed to prepare for foreseeable changes that already here. Lots of things that are climate-related but not only about climate change, like affordable housing, transportation, energy access for everyone so they can have services like cooking and the internet — those are things that we can change going forward. The hopeful message is: Cities are always changing and being built, so we should make them better. The urgent message is: We shouldn’t accept the status quo. More

      Putting public service into practice

      by

      Salomé Otero ’23 doesn’t mince words about the social impact internship she had in 2022. “It was transformational for me,” she says.

      Otero, who majored in management with a concentration in education, always felt that education would play some role in her career path after MIT, but she wasn’t sure how. That all changed her junior year, when she got an email from the Priscilla King Gray Public Service Center (PKG Center) about an internship at The Last Mile, a San Francisco-based nonprofit that provides education and technology training for justice-impacted individuals.

      Otero applied and was selected as a web curriculum and re-entry intern at The Last Mile the summer between her junior and senior year — an eye-opening experience that cemented her post-graduation plans. “You hear some amazing stories, like this person was incarcerated before the iPhone had come out. Now he’s a software developer,” she explains. “And for me, the idea of using computer science education for good appealed to me on many fronts. But even if I hadn’t gotten the opportunity to work at The Last Mile, the fact that I saw a job description for this role and learned that companies have the resources to make a difference … I didn’t know that there were people and organizations dedicating their time and energy into this.”

      She was so inspired that, when she returned for her senior year, Otero found work at two education labs at MIT, completed another social impact internship over Independent Activities Period (IAP) at G{Code}, an education nonprofit that provides computer science education to women and nonbinary people of color, and decided to apply to graduate school. “I can tell you with 100 percent certainty that I would not be pursuing a PhD in education policy right now if it weren’t for the PKG Center,” she says. She will begin her doctorate this fall.

      Otero’s experience doesn’t surprise Jill Bassett, associate dean and director of the PKG Center. “MIT students are deeply concerned about the world’s most challenging problems,” she says. “And social impact internships are an incredible way for them to leverage their unique talents and skills to help create meaningful change while broadening their perspectives and discovering potential career paths.”

      “There’s a lot more out there”

      Founded 35 years ago, the PKG Center offers a robust portfolio of experiential learning programs broadly focused on four themes: climate change, health equity, racial justice, and tech for social good. The Center’s Social Impact Internship Program provides funded internships to students interested in working with government agencies, nonprofits, and social ventures. Students reap rich rewards from these experiences, including learning ways to make social change, informing their academic journey and career path, and gaining valuable professional skills.

      “It was a really good learning opportunity,” says Juliet Liao ’23, a graduate of MIT’s Naval ROTC program who commissioned as a submarine officer in June. She completed a social impact internship with the World Wildlife Fund, where she researched greenhouse gas emissions related to the salmon industry. “I haven’t had much exposure to what work outside of the Navy looks like and what I’m interested in working on. And I really liked the science-based approach to mitigating greenhouse gas emissions.”

      Amina Abdalla, a rising junior in biological engineering, arrived at MIT with a strong interest in health care and determined to go to medical school. But her internship at MassHealth, the Medicaid and Children’s Health Insurance Program provider for the state of Massachusetts, broadened her understanding of the complexity of the health care system and introduced her to many career options that she didn’t know existed.

      “They did coffee chats between interns and various people who work in MassHealth, such as doctors, lawyers, policy advocates, and consultants. There’s a lot more out there that one can do with the degree that they get and the knowledge they gain. It just depends on your interests, and I came away from that really excited,” she says. The experience inspired her to take a class in health policy before she graduates. “I know I want to be a doctor and I have a lot of interest in science in general, but if I could do some kind of public sector impact with that knowledge, I would definitely be interested in doing that.”

      Social impact internships also provide an opportunity for students to hone their analytical, technical, and people skills. Selma Sharaf ’22 worked on developing a first-ever climate action plan for Bennett College in Greensboro, North Carolina, one of two all-women’s historically Black colleges and universities in the United States. She conducted research and stakeholder interviews with nonprofits; sustainability directors at similar colleges; local utility companies; and faculty, staff, and students at Bennett.

      “Our external outreach efforts with certain organizations allowed me to practice having conversations about energy justice and climate issues with people who aren’t already in this space. I learned how useful it can be to not only discuss the overall issues of climate change and carbon emissions, but to also zoom in on more relatable personal-level impacts,” she says. Sharaf is currently working in clean energy consulting and plans to pursue a master’s degree at Stanford University’s Atmosphere/Energy Program this fall.

      Working with “all stars”

      Organizations that partner with the PKG Center are often constrained by limited technical and financial resources. Since the program is funded by the PKG Center, these internships help expand their organizational capacity and broaden their impact; MIT students can take on projects that might not otherwise get done, and they also bring fresh skills and ideas to the organization — and the zeal to pursue those ideas.

      Emily Moberg ’11, PhD ’16 got involved with the social impact internship programs in 2020. Moberg, who is the director of Scope 3 Carbon Measurement and Mitigation at the World Wildlife Fund, has worked with 20 MIT students since then, including Liao. The body of work that Liao and several other interns completed has been published in the form of 10 briefs onmitigating greenhouse gas emissions from key commodities, such as soy, beef, coffee, and palm oil.

      “Social impact interns bring technical skills, deep curiosity, and tenacity,” Moberg says. “I’ve worked with students across many majors, including computer and materials science; all of them bring a new, fresh perspective to our problems and often sophisticated quantitative ability. Their presence often helps us to investigate new ideas or expand a project. In some cases, interns have proposed new projects and ideas themselves. The support from the PKG Center for us to host these interns has been critical, especially for these new explorations.”

      Anne Carrington Hayes, associate professor and executive director of the Global Leadership and Interdisciplinary Studies program at Bennett College, calls the MIT interns she’s worked with since 2021 “all stars.” The work Sharaf and three other students performed has culminated in a draft climate action plan that will inform campus renovations and other measures that will be implemented at the college in the coming years.

      “They have been foundational in helping me to research, frame, collect data, and engage with our students and the community around issues of environmental justice and sustainability, particularly from the lens of what would be impactful and meaningful for women of color at Bennett College,” she says.

      Balancing supply and demand

      Bassett says that the social impact internship program has grown exponentially in the past few years. Before the pandemic, the program served five students from summer 2019 to spring 2020; it now serves about 125 students per year. Over that time, funding has become a significant limiting factor; demand for internships was three times the number of available internships in summer 2022, and five times the supply during IAP 2023.

      “MIT students have no shortage of opportunities available to them in the private sector, yet students are seeking social impact internships because they want to apply their skills to issues that they care about,” says Julie Uva, the PKG Center’s program administrator for social impact internships and employment. “We want to ensure every student who wants a social impact internship can access that experience.”

      MIT has taken note of this financial shortfall: the Task Force 2021 report recommended fundraising to alleviate the under-supply of social impact experiential learning opportunities (ELOs), and MIT’s Fast Forward Climate Action Plan called on the Institute to make a climate or clean-energy ELOs available to every undergraduate who wants one. As a result, the Office of Experiential Learning is working with Resource Development to raise new funding to support many more opportunities, which would be available to students not only through the PKG Center but also other offices and programs, such as MIT D-Lab, Undergraduate Research Opportunity Programs, MISTI, and the Environmental Solutions Initiative, among others.

      That’s welcome news to Salomé Otero. She’s familiar with the Institute’s fundraising efforts, having worked as one of the Alumni Association’s Tech Callers. Now, as an alumna herself and a former social impact intern, she has an appreciation for the power of philanthropy.

      “MIT is ahead of the game compared to so many universities, in so many ways,” she says. “But if they want to continue to do that in the most impactful way possible, I think investing in ideas and missions like the PKG Center is the way to go. So when that call comes, I’ll tell whoever is working that night shift, ‘Yeah, I’ll donate to the PKG Center.’” More

      New clean air and water labs to bring together researchers, policymakers to find climate solutions

      by

      MIT’s Abdul Latif Jameel Poverty Action Lab (J-PAL) is launching the Clean Air and Water Labs, with support from Community Jameel, to generate evidence-based solutions aimed at increasing access to clean air and water.

      Led by J-PAL’s Africa, Middle East and North Africa (MENA), and South Asia regional offices, the labs will partner with government agencies to bring together researchers and policymakers in areas where impactful clean air and water solutions are most urgently needed.

      Together, the labs aim to improve clean air and water access by informing the scaling of evidence-based policies and decisions of city, state, and national governments that serve nearly 260 million people combined.

      The Clean Air and Water Labs expand the work of J-PAL’s King Climate Action Initiative, building on the foundational support of King Philanthropies, which significantly expanded J-PAL’s work at the nexus of climate change and poverty alleviation worldwide. 

      Air pollution, water scarcity and the need for evidence 

      Africa, MENA, and South Asia are on the front lines of global air and water crises. 

      “There is no time to waste investing in solutions that do not achieve their desired effects,” says Iqbal Dhaliwal, global executive director of J-PAL. “By co-generating rigorous real-world evidence with researchers, policymakers can have the information they need to dedicate resources to scaling up solutions that have been shown to be effective.”

      In India, about 75 percent of households did not have drinking water on premises in 2018. In MENA, nearly 90 percent of children live in areas facing high or extreme water stress. Across Africa, almost 400 million people lack access to safe drinking water. 

      Simultaneously, air pollution is one of the greatest threats to human health globally. In India, extraordinary levels of air pollution are shortening the average life expectancy by five years. In Africa, rising indoor and ambient air pollution contributed to 1.1 million premature deaths in 2019. 

      There is increasing urgency to find high-impact and cost-effective solutions to the worsening threats to human health and resources caused by climate change. However, data and evidence on potential solutions are limited.

      Fostering collaboration to generate policy-relevant evidence 

      The Clean Air and Water Labs will foster deep collaboration between government stakeholders, J-PAL regional offices, and researchers in the J-PAL network. 

      Through the labs, J-PAL will work with policymakers to:

      co-diagnose the most pressing air and water challenges and opportunities for policy innovation;
      expand policymakers’ access to and use of high-quality air and water data;
      co-design potential solutions informed by existing evidence;
      co-generate evidence on promising solutions through rigorous evaluation, leveraging existing and new data sources; and
      support scaling of air and water policies and programs that are found to be effective through evaluation. 
      A research and scaling fund for each lab will prioritize resources for co-generated pilot studies, randomized evaluations, and scaling projects. 

      The labs will also collaborate with C40 Cities, a global network of mayors of the world’s leading cities that are united in action to confront the climate crisis, to share policy-relevant evidence and identify opportunities for potential new connections and research opportunities within India and across Africa.

      This model aims to strengthen the use of evidence in decision-making to ensure solutions are highly effective and to guide research to answer policymakers’ most urgent questions. J-PAL Africa, MENA, and South Asia’s strong on-the-ground presence will further bridge research and policy work by anchoring activities within local contexts. 

      “Communities across the world continue to face challenges in accessing clean air and water, a threat to human safety that has only been exacerbated by the climate crisis, along with rising temperatures and other hazards,” says George Richards, director of Community Jameel. “Through our collaboration with J-PAL and C40 in creating climate policy labs embedded in city, state, and national governments in Africa and South Asia, we are committed to innovative and science-based approaches that can help hundreds of millions of people enjoy healthier lives.”

      J-PAL Africa, MENA, and South Asia will formally launch Clean Air and Water Labs with government partners over the coming months. J-PAL is housed in the MIT Department of Economics, within the School of Humanities, Arts, and Social Sciences. More

      Ms. Nuclear Energy is winning over nuclear skeptics

      by

      First-year MIT nuclear science and engineering (NSE) doctoral student Kaylee Cunningham is not the first person to notice that nuclear energy has a public relations problem. But her commitment to dispel myths about the alternative power source has earned her the moniker “Ms. Nuclear Energy” on TikTok and a devoted fan base on the social media platform.

      Cunningham’s activism kicked into place shortly after a week-long trip to Iceland to study geothermal energy. During a discussion about how the country was going to achieve its net zero energy goals, a representative from the University of Reykjavik balked at Cunnigham’s suggestion of including a nuclear option in the alternative energy mix. “The response I got was that we’re a peace-loving nation, we don’t do that,” Cunningham remembers. “I was appalled by the reaction, I mean we’re talking energy not weapons here, right?” she asks. Incredulous, Cunningham made a TikTok that targeted misinformation. Overnight she garnered 10,000 followers and “Ms. Nuclear Energy” was off to the races. Ms. Nuclear Energy is now Cunningham’s TikTok handle.

      Kaylee Cunningham: Dispelling myths and winning over skeptics

      A theater and science nerd

      TikTok is a fitting platform for a theater nerd like Cunningham. Born in Melrose, Massachusetts, Cunningham’s childhood was punctuated by moves to places where her roofer father’s work took the family. She moved to North Carolina shortly after fifth grade and fell in love with theater. “I was doing theater classes, the spring musical, it was my entire world,” Cunningham remembers. When she moved again, this time to Florida halfway through her first year of high school, she found the spring musical had already been cast. But she could help behind the scenes. Through that work, Cunningham gained her first real exposure to hands-on tech. She was hooked.

      Soon Cunningham was part of a team that represented her high school at the student Astronaut Challenge, an aerospace competition run by Florida State University. Statewide winners got to fly a space shuttle simulator at the Kennedy Space Center and participate in additional engineering challenges. Cunningham’s team was involved in creating a proposal to help NASA’s Asteroid Redirect Mission, designed to help the agency gather a large boulder from a near-earth asteroid. The task was Cunningham’s induction into an understanding of radiation and “anything nuclear.” Her high school engineering teacher, Nirmala Arunachalam, encouraged Cunningham’s interest in the subject.

      The Astronaut Challenge might just have been the end of Cunningham’s path in nuclear engineering had it not been for her mother. In high school, Cunningham had also enrolled in computer science classes and her love of the subject earned her a scholarship at Norwich University in Vermont where she had pursued a camp in cybersecurity. Cunningham had already laid down the college deposit for Norwich.

      But Cunningham’s mother persuaded her daughter to pay another visit to the University of Florida, where she had expressed interest in pursuing nuclear engineering. To her pleasant surprise, the department chair, Professor James Baciak, pulled out all the stops, bringing mother and daughter on a tour of the on-campus nuclear reactor and promising Cunningham a paid research position. Cunningham was sold and Backiak has been a mentor throughout her research career.

      Merging nuclear engineering and computer science

      Undergraduate research internships, including one at Oak Ridge National Laboratory, where she could combine her two loves, nuclear engineering and computer science, convinced Cunningham she wanted to pursue a similar path in graduate school.

      Cunningham’s undergraduate application to MIT had been rejected but that didn’t deter her from applying to NSE for graduate school. Having spent her early years in an elementary school barely 20 minutes from campus, she had grown up hearing that “the smartest people in the world go to MIT.” Cunningham figured that if she got into MIT, it would be “like going back home to Massachusetts” and that she could fit right in.

      Under the advisement of Professor Michael Short, Cunningham is looking to pursue her passions in both computer science and nuclear engineering in her doctoral studies.

      The activism continues

      Simultaneously, Cunningham is determined to keep her activism going.

      Her ability to digest “complex topics into something understandable to people who have no connection to academia” has helped Cunningham on TikTok. “It’s been something I’ve been doing all my life with my parents and siblings and extended family,” she says.

      Punctuating her video snippets with humor — a Simpsons reference is par for the course — helps Cunningham break through to her audience who love her goofy and tongue-in-cheek approach to the subject matter without compromising accuracy. “Sometimes I do stupid dances and make a total fool of myself, but I’ve really found my niche by being willing to engage and entertain people and educate them at the same time.”

      Such education needs to be an important part of an industry that’s received its share of misunderstandings, Cunningham says. “Technical people trying to communicate in a way that the general people don’t understand is such a concerning thing,” she adds. Case in point: the response in the wake of the Three Mile Island accident, which prevented massive contamination leaks. It was a perfect example of how well our safety regulations actually work, Cunningham says, “but you’d never guess from the PR fallout from it all.”

      As Ms. Nuclear Energy, Cunningham receives her share of skepticism. One viewer questioned the safety of nuclear reactors if “tons of pollution” was spewing out from them. Cunningham produced a TikTok that addressed this misconception. Pointing to the “pollution” in a photo, Cunningham clarifies that it’s just water vapor. The TikTok has garnered over a million views. “It really goes to show how starving for accurate information the public really is,” Cunningham says, “ in this age of having all the information we could ever want at our fingertips, it’s hard to sift through and decide what’s real and accurate and what isn’t.”

      Another reason for her advocacy: doing her part to encourage young people toward a nuclear science or engineering career. “If we’re going to start putting up tons of small modular reactors around the country, we need people to build them, people to run them, and we need regulatory bodies to inspect and keep them safe,” Cunningham points out. “ And we don’t have enough people entering the workforce in comparison to those that are retiring from the workforce,” she adds. “I’m able to engage those younger audiences and put nuclear engineering on their radar,” Cunningham says. The advocacy has been paying off: Cunningham regularly receives — and responds to — inquiries from high school junior girls looking for advice on pursuing nuclear engineering.

      All the activism is in service toward a clear end goal. “At the end of the day, the fight is to save the planet,” Cunningham says, “I honestly believe that nuclear power is the best chance we’ve got to fight climate change and keep our planet alive.” More

      Explained: The 1.5 C climate benchmark

      by

      The summer of 2023 has been a season of weather extremes.

      In June, uncontrolled wildfires ripped through parts of Canada, sending smoke into the U.S. and setting off air quality alerts in dozens of downwind states. In July, the world set the hottest global temperature on record, which it held for three days in a row, then broke again on day four.

      From July into August, unrelenting heat blanketed large parts of Europe, Asia, and the U.S., while India faced a torrential monsoon season, and heavy rains flooded regions in the northeastern U.S. And most recently, whipped up by high winds and dry vegetation, a historic wildfire tore through Maui, devastating an entire town.

      These extreme weather events are mainly a consequence of climate change driven by humans’ continued burning of coal, oil, and natural gas. Climate scientists agree that extreme weather such as what people experienced this summer will likely grow more frequent and intense in the coming years unless something is done, on a persistent and planet-wide scale, to rein in global temperatures.

      Just how much reining-in are they talking about? The number that is internationally agreed upon is 1.5 degrees Celsius. To prevent worsening and potentially irreversible effects of climate change, the world’s average temperature should not exceed that of preindustrial times by more than 1.5 degrees Celsius (2.7 degrees Fahrenheit).

      As more regions around the world face extreme weather, it’s worth taking stock of the 1.5-degree bar, where the planet stands in relation to this threshold, and what can be done at the global, regional, and personal level, to “keep 1.5 alive.”

      Why 1.5 C?

      In 2015, in response to the growing urgency of climate impacts, nearly every country in the world signed onto the Paris Agreement, a landmark international treaty under which 195 nations pledged to hold the Earth’s temperature to “well below 2 degrees Celsius above pre-industrial levels,” and going further, aim to “limit the temperature increase to 1.5 degrees Celsius above pre-industrial levels.”

      The treaty did not define a particular preindustrial period, though scientists generally consider the years from 1850 to 1900 to be a reliable reference; this time predates humans’ use of fossil fuels and is also the earliest period when global observations of land and sea temperatures are available. During this period, the average global temperature, while swinging up and down in certain years, generally hovered around 13.5 degrees Celsius, or 56.3 degrees Fahrenheit.

      The treaty was informed by a fact-finding report which concluded that, even global warming of 1.5 degrees Celsius above the preindustrial average, over an extended, decades-long period, would lead to high risks for “some regions and vulnerable ecosystems.” The recommendation then, was to set the 1.5 degrees Celsius limit as a “defense line” — if the world can keep below this line, it potentially could avoid the more extreme and irreversible climate effects that would occur with a 2 degrees Celsius increase, and for some places, an even smaller increase than that.

      But, as many regions are experiencing today, keeping below the 1.5 line is no guarantee of avoiding extreme, global warming effects.

      “There is nothing magical about the 1.5 number, other than that is an agreed aspirational target. Keeping at 1.4 is better than 1.5, and 1.3 is better than 1.4, and so on,” says Sergey Paltsev, deputy director of MIT’s Joint Program on the Science and Policy of Global Change. “The science does not tell us that if, for example, the temperature increase is 1.51 degrees Celsius, then it would definitely be the end of the world. Similarly, if the temperature would stay at 1.49 degrees increase, it does not mean that we will eliminate all impacts of climate change. What is known: The lower the target for an increase in temperature, the lower the risks of climate impacts.”

      How close are we to 1.5 C?

      In 2022, the average global temperature was about 1.15 degrees Celsius above preindustrial levels. According to the World Meteorological Organization (WMO), the cyclical weather phenomenon La Niña recently contributed to temporarily cooling and dampening the effects of human-induced climate change. La Niña lasted for three years and ended around March of 2023.

      In May, the WMO issued a report that projected a significant likelihood (66 percent) that the world would exceed the 1.5 degrees Celsius threshold in the next four years. This breach would likely be driven by human-induced climate change, combined with a warming El Niño — a cyclical weather phenomenon that temporarily heats up ocean regions and pushes global temperatures higher.

      This summer, an El Niño is currently underway, and the event typically raises global temperatures in the year after it sets in, which in this case would be in 2024. The WMO predicts that, for each of the next four years, the global average temperature is likely to swing between 1.1 and 1.8 degrees Celsius above preindustrial levels.

      Though there is a good chance the world will get hotter than the 1.5-degree limit as the result of El Niño, the breach would be temporary, and for now, would not have failed the Paris Agreement, which aims to keep global temperatures below the 1.5-degree limit over the long term (averaged over several decades rather than a single year).

      “But we should not forget that this is a global average, and there are variations regionally and seasonally,” says Elfatih Eltahir, the H.M. King Bhumibol Professor and Professor of Civil and Environmental Engineering at MIT. “This year, we had extreme conditions around the world, even though we haven’t reached the 1.5 C threshold. So, even if we control the average at a global magnitude, we are going to see events that are extreme, because of climate change.”

      More than a number

      To hold the planet’s long-term average temperature to below the 1.5-degree threshold, the world will have to reach net zero emissions by the year 2050, according to the Intergovernmental Panel on Climate Change (IPCC). This means that, in terms of the emissions released by the burning of coal, oil, and natural gas, the entire world will have to remove as much as it puts into the atmosphere.

      “In terms of innovations, we need all of them — even those that may seem quite exotic at this point: fusion, direct air capture, and others,” Paltsev says.

      The task of curbing emissions in time is particularly daunting for the United States, which generates the most carbon dioxide emissions of any other country in the world.

      “The U.S.’s burning of fossil fuels and consumption of energy is just way above the rest of the world. That’s a persistent problem,” Eltahir says. “And the national statistics are an aggregate of what a lot of individuals are doing.”

      At an individual level, there are things that can be done to help bring down one’s personal emissions, and potentially chip away at rising global temperatures.

      “We are consumers of products that either embody greenhouse gases, such as meat, clothes, computers, and homes, or we are directly responsible for emitting greenhouse gases, such as when we use cars, airplanes, electricity, and air conditioners,” Paltsev says. “Our everyday choices affect the amount of emissions that are added to the atmosphere.”

      But to compel people to change their emissions, it may be less about a number, and more about a feeling.

      “To get people to act, my hypothesis is, you need to reach them not just by convincing them to be good citizens and saying it’s good for the world to keep below 1.5 degrees, but showing how they individually will be impacted,” says Eltahir, who specializes on the study of regional climates, focusing on how climate change impacts the water cycle and frequency of extreme weather such as heat waves.

      “True climate progress requires a dramatic change in how the human system gets its energy,” Paltsev says. “It is a huge undertaking. Are you ready personally to make sacrifices and to change the way of your life? If one gets an honest answer to that question, it would help to understand why true climate progress is so difficult to achieve.” More

      Q&A: Three Tata Fellows on the program’s impact on themselves and the world

      by

      The Tata Fellowship at MIT gives graduate students the opportunity to pursue interdisciplinary research and work with real-world applications in developing countries. Part of the MIT Tata Center for Technology and Design, this fellowship contributes to the center’s goal of designing appropriate, practical solutions for resource-constrained communities. Three Tata Fellows — Serena Patel, Rameen Hayat Malik, and Ethan Harrison — discuss the impact of this program on their research, perspectives, and time at MIT.

      Serena Patel

      Serena Patel graduated from the University of California at Berkeley with a degree in energy engineering and a minor in energy and resources. She is currently pursuing her SM in technology and policy at MIT and is a Tata Fellow focusing on decarbonization in India using techno-economic modeling. Her interest in the intersection of technology, policy, economics, and social justice led her to attend COP27, where she experienced decision-maker and activist interactions firsthand.

      Q: How did you become interested in the Tata Fellowship, and how has it influenced your time at MIT?

      A: The Tata Center appealed to my interest in searching for creative, sustainable energy technologies that center collaboration with local-leading organizations. It has also shaped my understanding of the role of technology in sustainable development planning. Our current energy system disproportionately impacts marginalized communities, and new energy systems have the potential to perpetuate and/or create inequities. I am broadly interested in how we can put people at the core of our technological solutions and support equitable energy transitions. I specifically work on techno-economic modeling to analyze the potential for an early retirement of India’s large coal fleet and conversion to long-duration thermal energy storage. This could mitigate job losses from rapid transitions, support India’s energy system decarbonization plan, and provide a cost-effective way to retire stranded assets.

      Q: Why is interdisciplinary study important to real-world solutions for global communities, and how has working at the intersection of technology and policy influenced your research?

      A: Technology and policy work together in mediating and regulating the world around us. Technological solutions can be disruptive in all the good ways, but they can also do a lot of harm and perpetuate existing inequities. Interdisciplinary studies are important to mitigate these interrelated issues so innovative ideas in the ivory towers of Western academia do not negatively impact marginalized communities. For real-world solutions to positively impact individuals, marginalized communities need to be centered within the research design process. I think the research community’s perspective on real-world, global solutions is shifting to achieve these goals, but much work remains for resources to reach the right communities.

      The energy space is especially fascinating because it impacts everyone’s quality of life in overt or nuanced ways. I’ve had the privilege of taking classes that sit at the intersection of energy technology and policy, involving land-use law, geographic representation, energy regulation, and technology policy. In general, working at the intersection of technology and policy has shaped my perspective on how regulation influences widespread technology adoption and the overall research directions and assumptions in our energy models.

      Q: How has your experience at COP27 influenced your approach to your research?

      A: Attending COP27 at Sharm El-Sheikh, Egypt, last November influenced my understanding of the role of science, research, and activism in climate negotiations and action. Science and research are often promoted as necessary for sharing knowledge at the higher levels, but they were also used as a delay tactic by negotiators. I heard how institutional bodies meant to support fair science and research often did not reach intended stakeholders. Lofty goals or financial commitments to ensure global climate stability and resilience still lacked implementation and coordination with deep technology transfer and support. On the face of it, these agreements have impact and influence, but I heard many frustrations over the lack of tangible, local support. This has driven my research to be as context-specific as possible, to provide actionable insights and leverage different disciplines.

      I also observed the role of activism in the negotiations. Decision-makers are accountable to their country, and activists are spreading awareness and bringing transparency to the COP process. As a U.S. citizen, I suddenly became more aware of how political engagement and awareness in the country could push the boundaries of international climate agreements if the government were more aligned on climate action.

      Rameen Hayat Malik

      Rameen Hayat Malik graduated from the University of Sydney with a bachelor’s degree in chemical and biomolecular engineering and a Bachelor of Laws. She is currently pursuing her SM in technology and policy and is a Tata Fellow researching the impacts of electric vehicle (EV) battery production in Indonesia. Originally from Australia, she first became interested in the geopolitical landscape of resources trade and its implications for the clean energy transition while working in her native country’s Department of Climate Change, Energy, the Environment and Water.

      Q: How did you become interested in the Tata Fellowship, and how has it influenced your time at MIT?

      A: I came across the Tata Fellowship while looking for research opportunities that aligned with my interest in understanding how a just energy transition will occur in a global context, with a particular focus on emerging economies. My research explores the techno-economic, social, and environmental impacts of nickel mining in Indonesia as it seeks to establish itself as a major producer of EV batteries. The fellowship’s focus on community-driven research has given me the freedom to guide the scope of my research. It has allowed me to integrate a community voice into my work that seeks to understand the impact of this mining on forest-dependent communities, Indigenous communities, and workforce development.

      Q: Battery technology and production are highly discussed in the energy sector. How does your research on Indonesia’s battery production contribute to the current discussion around batteries, and what drew you to this topic?

      A: Indonesia is one of the world’s largest exporters of coal, while also having one of the largest nickel reserves in the world — a key mineral for EV battery production. This presents an exciting opportunity for Indonesia to be a leader in the energy transition, as it both seeks to phase out coal production and establish itself as a key supplier of critical minerals. It is also an opportunity to actually apply principles of a just transition to the region, which seeks to repurpose and re-skill existing coal workforces, to bring Indigenous communities into the conversation around the future of their lands, and to explore whether it is actually possible to sustainably and ethically produce nickel for EV battery production.

      I’ve always seen battery technologies and EVs as products that, at least today, are accessible to a small, privileged customer base that can afford such technologies. I’m interested in understanding how we can make such products more widely affordable and provide our lowest-income communities with the opportunities to actively participate in the transition — especially since access to transportation is a key driver of social mobility. With nickel prices impacting EV prices in such a dramatic way, unlocking more nickel supply chains presents an opportunity to make EV batteries more accessible and affordable.

      Q: What advice would you give to new students who want to be a part of real-world solutions to the climate crisis?

      A: Bring your whole self with you when engaging these issues. Quite often we get caught up with the technology or modeling aspect of addressing the climate crisis and forget to bring people and their experiences into our work. Think about your positionality: Who is your community, what are the avenues you have to bring that community along, and what privileges do you hold to empower and amplify voices that need to be heard? Find a piece of this complex puzzle that excites you, and find opportunities to talk and listen to people who are directly impacted by the solutions you are looking to explore. It can get quite overwhelming working in this space, which carries a sense of urgency, politicization, and polarization with it. Stay optimistic, keep advocating, and remember to take care of yourself while doing this important work.

      Ethan Harrison

      After earning his degree in economics and applied science from the College of William and Mary, Ethan Harrison worked at the United Nations Development Program in its Crisis Bureau as a research officer focused on conflict prevention and predictive analysis. He is currently pursuing his SM in technology and policy at MIT. In his Tata Fellowship, he focuses on the impacts of the Ukraine-Russia conflict on global vulnerability and the global energy market.

      Q: How did you become interested in the Tata Fellowship, and how has it influenced your time at MIT?

      A: Coming to MIT, one of my chief interests was figuring out how we can leverage gains from technology to improve outcomes and build pro-poor solutions in developing and crisis contexts. The Tata Fellowship aligned with many of the conclusions I drew while working in crisis contexts and some of the outstanding questions that I was hoping to answer during my time at MIT, specifically: How can we leverage technology to build sustainable, participatory, and ethically grounded interventions in these contexts?

      My research currently examines the secondary impacts of the Ukraine-Russia conflict on low- and middle-income countries — especially fragile states — with a focus on shocks in the global energy market. This includes the development of a novel framework that systematically identifies factors of vulnerability — such as in energy, food systems, and trade dependence — and quantitatively ranks countries by their level of vulnerability. By identifying the specific mechanisms by which these countries are vulnerable, we can develop a map of global vulnerability and identify key policy solutions that can insulate countries from current and future shocks.

      Q: I understand that your research deals with the relationship between oil and gas price fluctuation and political stability. What has been the most surprising aspect of this relationship, and what are its implications for global decarbonization?

      A: One surprising aspect is the degree to which citizen grievances regarding price fluctuations can quickly expand to broader democratic demands and destabilization. In Sri Lanka last year and in Egypt during the Arab spring, initial protests around fuel prices and power outages eventually led to broader demands and the loss of power by heads of state. Another surprising aspect is the popularity of fuel subsidies despite the fact that they are economically regressive: They often comprise a large proportion of GDP in poor countries, disproportionately benefit higher-income populations, and leave countries vulnerable to fiscal stress during price spikes.

      Regarding implications for global decarbonization, one project we are pursuing examines the implications of directing financing from fuel subsidies toward investments in renewable energy. Countries that rely on fossil fuels for electricity have been hit especially hard 
by price spikes from the Ukraine-Russia conflict, especially since many were carrying costly fuel subsidies to keep the price of fuel and energy artificially low. Much of the international community is advocating for low-income countries to invest in renewables and reduce their fossil fuel burden, but it’s important to explore how global decarbonization can align with efforts to end energy poverty and other Sustainable Development Goals.

      Q: How does your research impact the Tata Center’s goal of transforming policy research into real-world solutions, and why is this important?

      A: The crisis in Ukraine has shifted the international community’s focus away from other countries in crisis, such as Yemen and Lebanon. By developing a global map of vulnerability, we’re building a large evidence base on which countries have been most impacted by this crisis. Most importantly, by identifying individual channels of vulnerability for each country, we can also identify the most effective policy solutions to insulate vulnerable populations from shocks. Whether that’s advocating for short-term social protection programs or identifying more medium-term policy solutions — like fuel banks or investment in renewables — we hope providing a detailed map of sources of vulnerability can help inform the global response to shocks imposed by the Russia-Ukraine conflict and post-Covid recovery.

      Dyanna Jaye: Bringing the urgency of organizing to climate policy

      by

      Growing up in the Tidewater region of Virginia, Dyanna Jaye had a front row seat to the climate crisis. She recalls beach stabilization efforts that pumped sand from the bottom of the ocean to the shore in response to rising sea levels. And every hurricane season, the streets would flood.

      “I was thinking at a younger age about some pretty big questions,” says Jaye. “Can I call this place home for the rest of my life? Probably not. The changes that we will endure because of climate change will probably make the place where I grew up unlivable in my lifetime.”

      Jaye attended the University of Virginia, where she studied environmental science and global development studies. She also started to get involved in organizing efforts around climate policy. The first campaign she was a part of aimed to retire UVA’s coal plant and move to more renewable energy.

      “We didn’t really win, but I learned a lot in that first campaign,” she says.

      Jaye went on to co-found the Sunrise Movement, which helped launch the Green New Deal as a framework for ambitious, holistic climate policy across the country.

      Now pursuing a master’s in city planning at MIT, Jaye is seeking a deeper understanding of how to implement climate-conscious policy across all levels of government. She hopes to bring the lessons learned back to her home state.

      “My goal is to make it back to Virginia and have a better of an idea of how to plan a multidecade transition that decarbonizes our economy while also building good jobs and protecting the fundamental things that we need in our life,” says Jaye. “Virginia was this place where I felt like I could see both ends of the climate crisis, and realized you need a holistic solution to address all aspects of this.”

      A foundation in organizing

      After graduating from the University of Virginia, Jaye led a delegation of young people from the U.S. to the United Nations to campaign for a global commitment to phase out fossil fuels and fund equitable climate solutions. At the time, the Paris climate agreement was being negotiated. Witnessing that process firsthand was eye-opening.

      Jaye realized to push the U.S. forward in the fight against climate change, she needed to help build a nationwide movement that could push the federal government to enact ambitious policy. Along with six like-minded friends, Jaye co-founded the Sunrise Movement.

      “It feels silly to say this now, but part of Sunrise was just to get climate change to be a more urgent issue, because at the time it was politically unpopular to even talk about it,” Jaye says. “The vision that became the Green New Deal was this plan to decarbonize our society within 10 years and bring all the benefits we can to build a stronger, more connected, and healthier society.”

      Jaye describes her five years with Sunrise as a “wild whirlwind.” As the national organizing director, she worked on engagement strategies to recruit new people to the movement. Following a few key wins at the polls, Sunrise grew from a handful of chapters concentrated in swing states to over 500 chapters across the nation.

      On the other side, crafting policy

      Though she is no longer directly involved with the Sunrise Movement, Jaye has moved onto a different stage of the fight. For the final year of her master’s, she will be writing her thesis while working with the Massachusetts Office of Climate Innovation and Resilience. The office is newly established as of this year, evidence of the federal funding wins that Sunrise helped make possible.

      “Transparently, we wanted to win a lot more,” says Jaye. “We had huge goals, but we did win a lot of things at the federal level. So, the time is now to get federal funding and move it through state implementation and planning, and it’s urgent.”

      The flexibility of the city planning program allows students to study theory while also putting that theory in practice in local government. Jaye’s thesis will focus on the best planning approach for full government strategy, informed by her work in the climate office. While previous climate policy focused purely on the environmental sector, effectively addressing climate change will take a multipronged approach touching every sector, from transportation to housing to energy distribution to food production.

      “What’s really cool about being in the government right now in Massachusetts is getting to see a model as they’re trying to take climate from being an environmental priority to a number one, whole-of-government challenge,” says Jaye. “It’s an issue that’s embedded into every department and level of our government.”

      As she finishes her master’s, Jaye is still keeping an eye toward home. While she isn’t in a rush to leave Massachusetts, she is always thinking about the lessons she’s learning can apply to Virginia. And by building skills in both planning and organizing, Jaye will be well-equipped to make an impact wherever she lands.

      “I still feel very committed to community organizing. We’re living in a divided time where our democracy is being challenged, and organizing is what we need to do to respond to that,” says Jaye. “We also need a lot more people diving in on the work of policy and governance to determine how we transition our economy and our energy system, how are we going to go about doing something like that. Right now, I’m feeling excited to be on that side of the work.” More
