New major crosses disciplines to address climate change

News Feed
Thursday, April 18, 2024

Lauren Aguilar knew she wanted to study energy systems at MIT, but before Course 1-12 (Climate System Science and Engineering) became a new undergraduate major, she didn't see an obvious path to study the systems aspects of energy, policy, and climate associated with the energy transition. Aguilar was drawn to the new major that was jointly launched by the departments of Civil and Environmental Engineering (CEE) and Earth, Atmospheric and Planetary Sciences (EAPS) in 2023. She could take engineering systems classes and gain knowledge in climate. “Having climate knowledge enriches my understanding of how to build reliable and resilient energy systems for climate change mitigation. Understanding upon what scale we can forecast and predict climate change is crucial to build the appropriate level of energy infrastructure,” says Aguilar. The interdisciplinary structure of the 1-12 major has students engaging with and learning from professors in different disciplines across the Institute. The blended major was designed to provide a foundational understanding of the Earth system and engineering principles — as well as an understanding of human and institutional behavior as it relates to the climate challenge. Students learn the fundamental sciences through subjects like an atmospheric chemistry class focused on the global carbon cycle or a physics class on low-carbon energy systems. The major also covers topics in data science and machine learning as they relate to forecasting climate risks and building resilience, in addition to policy, economics, and environmental justice studies. Junior Ananda Figueiredo was one of the first students to declare the 1-12 major. Her decision to change majors stemmed from a motivation to improve people’s lives, especially when it comes to equality. “I like to look at things from a systems perspective, and climate change is such a complicated issue connected to many different pieces of our society,” says Figueiredo. A multifaceted field of study The 1-12 major prepares students with the necessary foundational expertise across disciplines to confront climate change. Andrew Babbin, an academic advisor in the new degree program and the Cecil and Ida Green Career Development Associate Professor in EAPS, says the new major harnesses rigorous training encompassing science, engineering, and policy to design and execute a way forward for society. Within its first year, Course 1-12 has attracted students with a diverse set of interests, ranging from machine learning for sustainability to nature-based solutions for carbon management to developing the next renewable energy technology and integrating it into the power system. Academic advisor Michael Howland, the Esther and Harold E. Edgerton Assistant Professor of Civil and Environmental Engineering, says the best part of this degree is the students, and the enthusiasm and optimism they bring to the climate challenge. “We have students seeking to impact policy and students double-majoring in computer science. For this generation, climate change is a challenge for today, not for the future. Their actions inside and outside the classroom speak to the urgency of the challenge and the promise that we can solve it,” Howland says. The degree program also leaves plenty of space for students to develop and follow their interests. Sophomore Katherine Kempff began this spring semester as a 1-12 major interested in sustainability and renewable energy. Kempff was worried she wouldn’t be able to finish 1-12 once she made the switch to a different set of classes, but Howland assured her there would be no problems, based on the structure of 1-12. “I really like how flexible 1-12 is. There's a lot of classes that satisfy the requirements, and you are not pigeonholed. I feel like I'm going to be able to do what I'm interested in, rather than just following a set path of a major,” says Kempff. Kempff is leveraging her skills she developed this semester and exploring different career interests. She is interviewing for sustainability and energy-sector internships in Boston and MIT this summer, and is particularly interested in assisting MIT in meeting its new sustainability goals. Engineering a sustainable future The new major dovetail’s MIT’s commitment to address climate change with its steps in prioritizing and enhancing climate education. As the Institute continues making strides to accelerate solutions, students can play a leading role in changing the future.    “Climate awareness is critical to all MIT students, most of whom will face the consequences of the projection models for the end of the century,” says Babbin. “One-12 will be a focal point of the climate education mission to train the brightest and most creative students to engineer a better world and understand the complex science necessary to design and verify any solutions they invent." Justin Cole, who transferred to MIT in January from the University of Colorado, served in the U.S. Air Force for nine years. Over the course of his service, he had a front row seat to the changing climate. From helping with the wildfire cleanup in Black Forest, Colorado — after the state's most destructive fire at the time — to witnessing two category 5 typhoons in Japan in 2018, Cole's experiences of these natural disasters impressed upon him that climate security was a prerequisite to international security.  Cole was recently accepted into the MIT Energy and Climate Club Launchpad initiative where he will work to solve real-world climate and energy problems with professionals in industry. “All of the dots are connecting so far in my classes, and all the hopes that I have for studying the climate crisis and the solutions to it at MIT are coming true,” says Cole. With a career path that is increasingly growing, there is a rising demand for scientists and engineers who have both deep knowledge of environmental and climate systems and expertise in methods for climate change mitigation. “Climate science must be coupled with climate solutions. As we experience worsening climate change, the environmental system will increasingly behave in new ways that we haven’t seen in the past,” says Howland. “Solutions to climate change must go beyond good engineering of small-scale components. We need to ensure that our system-scale solutions are maximally effective in reducing climate change, but are also resilient to climate change. And there is no time to waste,” he says.

Combining engineering, earth system science, and the social sciences, Course 1-12 prepares students to develop climate solutions.

How thousands of fossil fuel lobbyists got access to UN climate talks – and then kept drilling

Exclusive: Research shows oil, gas and coal firms’ unprecedented access to Cop26-29, blocking urgent climate actionMore than 5,000 fossil fuel lobbyists were given access to the UN climate summits over the past four years, a period marked by a rise in catastrophic extreme weather, inadequate climate action and record oil and gas expansion, new research reveals.Lobbyists representing the interests of the oil, gas and coal industries – which are mostly responsible for climate breakdown – have been allowed to participate in the annual climate negotiations where states are meant to come in good faith and commit to ambitious policies to reduce greenhouse gas emissions.

More than 5,000 fossil fuel lobbyists were given access to the UN climate summits over the past four years, a period marked by a rise in catastrophic extreme weather, inadequate climate action and record oil and gas expansion, new research reveals.Lobbyists representing the interests of the oil, gas and coal industries – which are mostly responsible for climate breakdown – have been allowed to participate in the annual climate negotiations where states are meant to come in good faith and commit to ambitious policies to reduce greenhouse gas emissions.The roughly 5,350 lobbyists mingling with world leaders and climate negotiators in recent years worked for at least 859 fossil fuel organizations including trade groups, foundations and 180 oil, gas and coal companies involved in every part of the supply chain from exploration and production to distribution and equipment, research shared exclusively with the Guardian has found.Just 90 of the fossil fuel corporations that sent lobbyists to climate talks between 2021 and 2024 accounted for more than half (57%) of all the oil and gas produced last year, according to the analysis by Kick Big Polluters Out (KBPO), a coalition of 450 organizations campaigning to stop the fossil fuel industry blocking and delaying global climate action.These corporations, which include many of the world’s most profitable private and publicly owned oil and gas majors, accounted for the production of 33,699m barrels of oil equivalent in 2024 – enough to cover more than the entire area of Spain with a 1cm blanket of oil.The same 90 firms also account for almost two-thirds (63%) of all short-term upstream fossil fuel expansion projects which are gearing up for exploration and production, according to the newly released Global Oil and Gas Exit List – a dataset which includes more than 1,700 companies covering more than 90% of global oil and gas activity.If executed, these expansion projects will produce enough oil – 2.623m km² at 1cm thickness – to coat the entire landmass of seven European countries (France, Spain, Germany, Denmark, Sweden, Finland and Norway) combined.The findings have renewed calls for fossil fuel companies and other big polluters to be banned from the annual climate negotiations amid mounting scientific evidence that the world has failed to limit the rise in global temperatures to 1.5C above preindustrial levels,.“This information clearly exposes corporate capture of the global climate process … the space that should be about science and the people has been transformed into a large carbon business hall,” said Adilson Vieira, spokesperson for the Amazonian Work Group. “While forest communities fight for survival, the same companies that cause climate collapse buy credentials and political influence to continue expanding their fossil empires.”“Not only are Indigenous peoples on the frontlines of their extractive sites suffering human rights violations, but we also face the brunt of climate chaos on our lands with worsening floods, wildfires, and extreme heat waves. We need to take down the ‘for sale’ sign on Mother Earth and bar entry to Cop for oil and gas lobbyists,” said Brenna Yellowthunder, lead coordinator for the Indigenous Environmental Network, a member of KBPO.The 30th UN climate summit (Cop30) opens on Monday in Belem, a city in the Brazilian Amazon – the world’s largest rainforest, which is being destroyed by ever-expanding fossil fuel exploitation, industrial agriculture, and mining, among other extractive industries.The annual meetings are where every country in the world negotiates on how best to tackle the climate crisis. The decisions should be driven by the legally binding United Nations Framework Convention on Climate Change (UNFCCC) treaty, and the 2015 Paris agreement to curtail global heating to under 1.5C.The research analyses the fossil fuel lobbyists known to have attended the negotiations in Glasgow (Cop26), Sharm el-Sheikh (Cop27), Dubai (Cop28) and Baku (Cop29). Until then, information about lobbyists was not collated by the UNFCCC.Growing anger at the lack of meaningful action by the world’s wealthiest, most polluting countries has been compounded by revelations that the fossil fuel industry appears to be granted greater access to the climate talks than most countries.Last year, 1,773 registered fossil fuel lobbyists attended the summit in Azerbaijan – 70% more than the total number of delegates from the 10 most climate-vulnerable nations combined (1,033).But the true reach of fossil fuel tentacles is undoubtedly deeper as the lobbyists data excludes executives and other company representatives on official country delegations participating directly in the confidential negotiations, and those attending as guests of governments, known as overflow delegates.The largest number of known lobbyists in recent years were representing state-owned companies from the United Arab Emirates, Russia and Azerbaijan.Many of the world’s most profitable fossil fuel corporations have also been present at recent Cop summits, at a time when governments faced huge public pressure – but failed – to agree to phase out fossil fuels despite deadly climate impacts affecting every corner of the planet.Between 2021 and 2024, Shell sent a combined total of 37 lobbyists, BP sent 36, ExxonMobil 32 and Chevron 20.In the past five years, the four oil majors made more than $420bn in combined profits.On Friday the Exxon CEO Darren Woods will headline a Cop30 launch event in Brasilia hosted by the US chamber of commerce called Pragmatic Business Solutions for Carbon Accounting and Emission Reductions. The US, which like every state is legally obliged under international law to tackle the climate crisis, has withdrawn from the Paris agreement and is not sending a country delegation to the summit.Petrobas, the majority state owned Brazilian multinational which sent at least 28 lobbyists to the past four climate summits, was recently grant ed a licence to conduct exploratory oil drilling in the sea off the Amazon, which is home to multiple Indigenous communities and about 10% of the planet’s known species.A spokesperson said: “Petrobras will be present at COP30, as it has been at previous talks, because it recognizes the opportunity to discuss sustainable models… The company’s participation in COP30 reinforces its commitment to follow and contribute to international debates on climate and energy.”Shell, BP, ExxonMobil and Chevron did not respond to requests for comment.After years of campaigning by civil society groups, Cop delegates this year are being asked to publicly disclose who is funding their participation – and confirm that their objectives are in alignment with the UNFCCC. But the new transparency requirement excludes anyone in official government delegations or overflows, and calls for stricter conflict of interest protections to cut industry influence have not been adequately heeded, advocates say.“The new rules are a welcome start, but they come decades too late … and transparency without exclusion is performative. You cannot claim to fix a process already captured by the very corporations burning the planet and fueling wars,” said Mohammed Usrof, executive director of the Palestinian Institute for Climate Strategy. “The UNFCCC must move from disclosure to disqualification… without reform this process will not save the world, and instead, will just help bury it.”UNFCCC has been contacted for comment.

Climate Risk Rarely Leads to ECB Collateral Downgrade, Blog Finds

FRANKFURT (Reuters) -The European Central Bank is already factoring climate-related risk into the assessment of collateral used to borrow money...

FRANKFURT (Reuters) -The European Central Bank is already factoring climate-related risk into the assessment of collateral used to borrow money from the bank but this rarely leads to credit rating changes, a blog post published by the ECB said on Friday.The ECB's 2021 climate action plan made the integration of climate risks into its collateral framework a key priority and the bank expects climate risk to be factored into credit ratings of assets posted by banks when they borrow from the central bank."While climate risks are widely recognised, they rarely lead to rating changes," the blog post, which does not necessarily represent the ECB's views, argued. "Several persistent challenges still limit the full and consistent integration of climate change risk into credit ratings."The ECB is using both its own in-house credit assessment systems and external rating agencies to determine climate risk but neither method has so far had a huge impact on collateral valuation.When using its in-house system, the share of credit ratings affected by climate risks is below 4% and the adjustments made are typically limited to one rating grade, the blog said.In the case of external agencies, environmental, social, and governance factors influence approximately 13% to 19% of all rating actions across the major agencies but climate change-specific downgrades account for only 2% to 7%, the blog post argued.While actual risk may be greater, assessment is difficult because banks can mask the vulnerabilities of some debtors, risk mitigation strategies can reduce their perceived exposure and because rating horizons are short- and medium-term, whereas climate risks tend to be long term, the blog said."Furthermore, reliable, granular climate change-related data remain scarce, particularly for smaller issuers, sovereigns and structured finance," it argued.(Reporting by Balazs KoranyiEditing by Tomasz Janowski)Copyright 2025 Thomson Reuters.Photos You Should See – Oct. 2025

Where climate meets community

MIT’s Living Climate Futures Lab takes a human-centered approach to investigating a global challenge.

The MIT Living Climate Futures Lab (LCFL) centers the human dimensions of climate change, bringing together expertise from across MIT to address one of the world’s biggest challenges.The LCFL has three main goals: “addressing how climate change plays out in everyday life, focusing on community-oriented partnerships, and encouraging cross-disciplinary conversations around climate change on campus,” says Chris Walley, the SHASS Dean’s Distinguished Professor of Anthropology and head of MIT’s Anthropology Section. “We think this is a crucial direction for MIT and will make a strong statement about the kind of human-centered, interdisciplinary work needed to tackle this issue.”Walley is faculty lead of LCFL, working in collaboration with a group of 19 faculty colleagues and researchers. The LCFL began to coalesce in 2022 when MIT faculty and affiliates already working with communities dealing with climate change issues organized a symposium, inviting urban farmers, place-based environmental groups, and others to MIT. Since then, the lab has consolidated the efforts of faculty and affiliates representing disciplines from across the MIT School of Humanities, Arts, and Social Sciences (SHASS) and the Institute.Amah Edoh, a cultural anthropologist and managing director of LCFL, says the lab’s collaboration with community organizations and development of experiential learning classes aims to bridge the gap that can exist between the classroom and the real world.“Sometimes we can find ourselves in a bubble where we’re only in conversation with other people from within academia or our own field of practice. There can be a disconnect between what students are learning somewhat abstractly and the ‘real world’ experience of the issues” Edoh says. “By taking up topics from the multidimensional approach that experiential learning makes possible, students learn to take complexity as a given, which can help to foster more critical thinking in them, and inform their future practice in profound ways.”Edoh points out that the effects of climate change play out in a huge array of areas: health, food security, livelihoods, housing, and governance structures, to name a few.“The Living Climate Futures Lab supports MIT researchers in developing the long-term collaborations with community partners that are essential to adequately identifying and responding to the challenges that climate change creates in everyday life,” she says.Manduhai Buyandelger, professor of anthropology and one of the participants in LCFL, developed the class 21A.S01 (Anthro-Engineering: Decarbonization at the Million-Person Scale), which has in turn sparked related classes. The goal is “to merge technological innovation with people-centered environments.” Working closely with residents of Ulaanbaatar, Mongolia, Buyandelger and collaborator Mike Short, the Class of 1941 Professor of Nuclear Science and Engineering, helped develop a molten salt heat bank as a reusable energy source.“My work with Mike Short on energy and alternative heating in Mongolia helps to cultivate a new generation of creative and socially minded engineers who prioritize people in thinking about technical solutions,” Buyandelger says, adding, “In our course, we collaborate on creating interdisciplinary methods where we fuse anthropological methods with engineering innovations so that we can expand and deepen our approach to mitigate climate change.”Iselle Barrios ’25, says 21A.S01 was her first anthropology course. She traveled to Mongolia and was able to experience firsthand all the ways in which the air pollution and heating problem was much larger and more complicated than it seemed from MIT’s Cambridge, Massachusetts, campus.“It was my first exposure to anthropological and STS critiques of science and engineering, as well as international development,” says Barrios, a chemical engineering major. “It fundamentally reshaped the way I see the role of technology and engineers in the broader social context in which they operate. It really helped me learn to think about problems in a more holistic and people-centered way.”LCFL participant Alvin Harvey, a postdoc in the MIT Media Lab’s Space Enabled Research Group and a citizen of the Navajo Nation, works to incorporate traditional knowledge in engineering and science to “support global stewardship of earth and space ecologies.”"I envision the Living Climate Futures Lab as a collaborative space that can be an igniter and sustainer of relationships, especially between MIT and those whose have generational and cultural ties to land and space that is being impacted by climate change,” Harvey says. “I think everyone in our lab understands that protecting our climate future is a collective journey."Kate Brown, the Thomas M. Siebel Distinguished Professor in History of Science, is also a participant in LCFL. Her current interest is urban food sovereignty movements, in which working-class city dwellers used waste to create “the most productive agriculture in recorded human history,” Brown says. While pursuing that work, Brown has developed relationships and worked with urban farmers in Mansfield, Ohio, as well as in Washington and Amsterdam.Brown and Susan Solomon, the Lee and Geraldine Martin Professor of Environmental Studies and Chemistry, teach a class called STS.055 (Living Dangerously: Environmental Programs from 1900 to Today) that presents the environmental problems and solutions of the 20th century, and how some “solutions” created more problems over time. Brown also plans to teach a class on the history of global food production once she gets access to a small plot of land on campus for a lab site.“The Living Climate Futures Lab gives us the structure and flexibility to work with communities that are struggling to find solutions to the problems being created by the climate crisis,” says Brown.Earlier this year, the MIT Human Insight Collaborative (MITHIC) selected the Living Climate Futures Lab as its inaugural Faculty-Driven Initiative (FDI), which comes with a $500,000 seed grant.MIT Provost Anantha Chandrakasan, co-chair of MITHIC, says the LCFL exemplifies how we can confront the climate crisis by working in true partnership with the communities most affected.“By combining scientific insight with cultural understanding and lived experience, this initiative brings a deeper dimension to MIT’s climate efforts — one grounded in collaboration, empathy, and real-world impact,” says Chandrakasan.Agustín Rayo, the Kenan Sahin Dean of SHASS and co-chair of MITHIC, says the LCFL is precisely the type of interdisciplinary collaboration the FDI program was designed to support."By bringing together expertise from across MIT, I am confident the Living Climate Futures Lab will make significant contributions in the Institute’s effort to address the climate crisis," says Rayo.Walley said the seed grant will support a second symposium in 2026 to be co-designed with community groups, a suite of experiential learning classes, workshops, a speaker series, and other programming. Throughout this development phase, the lab will solicit donor support to build it into an ongoing MIT initiative and a leader in the response to climate change.

Climate Change Boosted Hurricane Melissa's Destructive Winds and Rain, Analysis Finds

An analysis from World Weather Attribution reports human-caused climate change intensified the winds and rainfall unleashed by Hurricane Melissa in the Caribbean

Human-caused climate change boosted the destructive winds and rain unleashed by Hurricane Melissa and increased the temperatures and humidity that fueled the storm, according to an analysis released Thursday.Melissa was one of the strongest Atlantic hurricanes to make landfall and brought destructive weather to Jamaica, Haiti, Dominican Republic and Cuba, causing dozens of deaths across the Caribbean. Roofs were torn off of homes, hospitals were damaged, roads were blocked by landslides and crop fields were ruined.The rapid analysis by World Weather Attribution found that climate change increased Melissa’s maximum wind speeds by 7% and made the rainfall 16% more intense. The scientists also wrote that the temperature and humidity in which the storm intensified were made six times more likely due to climate change compared to a pre-industrial world.Rapid attribution analyses are a type of research that study factors influencing an extreme weather event and explore what the event would have been like in a world without climate change. They are typically published days or weeks after an extreme weather event.Melissa slowly tracked across the region and drew in enormous amounts of energy from abnormally warm ocean water. The analysis reported ocean temperatures in Melissa’s path through the Caribbean were about 1.4°C (2.5°F) warmer compared to a pre-industrial climate.“Warmer ocean temperatures are effectively the engine that drives a hurricane … the warmer the ocean temperatures, the greater the wind speed a hurricane can have,” said Theodore Keeping, a climate scientist who works for WWA and contributed to the analysis.Melissa is the fourth storm in the Atlantic this year to undergo rapid intensification, which is when a tropical cyclone’s maximum sustained winds increase by at least 30 knots (about 35 mph or 56 kph) in 24 hours.“A hurricane this rare would actually have had wind speeds about 10 mph (16 kph) less extreme” in a pre-industrial climate, said Keeping. He said research links hurricane wind speeds to economic damage and there would have been less destruction caused by Melissa if the winds were slower.Scientists have linked rapid intensification of hurricanes in the Atlantic to human-caused climate change. Planet-warming gases released by humans, such as carbon dioxide, cause the atmosphere to hold more water vapor and increase ocean temperatures. Warmer oceans give hurricanes fuel to unleash more rain and strengthen more quickly. “It’s like basically taking a sponge and wringing it out, and climate change is making that sponge even larger,” said Brian Tang, a professor of atmospheric science at University at Albany.Tang, who was not involved in the WWA research, said the methodology of the study released Thursday seems robust, and one of the more novel aspects of the analysis was the connection the scientists drew between wind speeds and increase in damage, which he said is a challenging area of research.Andrew Dessler, professor of atmospheric sciences at Texas A&M University, who was not involved in the WWA research, said the findings of the rapid analysis are in line with existing research about climate change and tropical storms in the Atlantic. “This is completely consistent with our expectation of what’s going to happen in the future,” Dessler said.Rapid attribution analyses help fill the need for an explanation about the influence of climate change shortly after a catastrophic weather event occurs, said Dessler. He said such analyses are “very valuable as a quick look” before the scientists are able to do more time-consuming calculations. Dessler said one of the scariest aspects of Melissa was the storm's peak sustained winds of 185 mph (298 kph) winds. “That’s pretty rare to have a storm that strong. And I think that, to the extent that this is a harbinger of the future, it’s not good,” he said.The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.
