      Hearing Amazônia: MIT musicians in Manaus, Brazil

      by

      On Dec. 13, the MIT community came together for the premiere of “We Are The Forest,” a documentary by MIT Video Productions that tells the story of the MIT musicians who traveled to the Brazilian Amazon seeking culture and scientific exchange.

      The film features performances by Djuena Tikuna, Luciana Souza, Anat Cohen, and Evan Ziporyn, with music by Antônio Carlos Jobim. Fred Harris conducts the MIT Festival Jazz Ensemble and MIT Wind Ensemble and Laura Grill Jaye conducts the MIT Vocal Jazz Ensemble.

      The impact of ecological devastation in the Amazon reflects the climate crisis worldwide. During the Institute’s spring break in March 2023, nearly 80 student musicians became only the second student group from MIT to travel to the Brazilian Amazon. Inspired by the research and activism of Talia Khan ’20, who is currently a PhD candidate in MIT’s Department of Mechanical Engineering, the trip built upon experiences of the 2020-21 academic year when virtual visiting artists Luciana Souza and Anat Cohen lectured on Brazilian music and culture before joining the November 2021 launch of Hearing Amazônia — The Responsibility of Existence.

      This consciousness-raising project at MIT, sponsored by the Center for Art, Science and Technology (CAST), began with a concert featuring Brazilian and Amazonian music influenced by the natural world. The project was created and led by MIT director of wind and jazz ensembles and senior lecturer in music Frederick Harris Jr.

      The performance was part eulogy and part praise song: a way of bearing witness to loss, while celebrating the living and evolving cultural heritage of Amazonia. The event included short talks, one of which was by Khan. As the first MIT student to study in the Brazilian Amazonia (via MISTI-Brazil), she spoke of her research on natural botanical resins and traditional carimbó music in Santarém, Pará, Brazil. Soon after, as a Fulbright Scholar, Khan continued her research in Manaus, setting the stage for the most complex trip in the history of MIT Music and Theater Arts.“My experiences in the Brazilian Amazon changed my life,” enthuses Khan. “Getting to know Indigenous musicians and immersing myself in the culture of this part of the world helped me realize how we are all so connected.”

      “Talia’s experiences in Brazil convinced me that the Hearing Amazônia project needed to take a next essential step,” explains Harris. “I wanted to provide as many students as possible with a similar opportunity to bring their musical and scientific talents together in a deep and spiritual manner. She provided a blueprint for our trip to Manaus.”

      An experience of a lifetime

      A multitude of musicians from three MTA ensembles traveled to Manaus, located in the middle of the world’s largest rainforest and home to the National Institute of Amazonian Research (Instituto Nacional de Pesquisas da Amazônia, or INPA), the most important center for scientific studies in the Amazon region for international sustainability issues.

      Tour experiences included cultural/scientific exchanges with Indigenous Amazonians through Nobre Academia de Robótica and the São Sebastião community on the Tarumã Açu River, INPA, the Cultural Center of the Peoples of the Amazon, and the Museu da Amazônia. Musically, students connected with local Indigenous instrument builders and performed with the Amazonas State Jazz Orchestra and renowned vocalist and Indigenous activist Djuena Tikuna.

      “Hearing Amazônia: Arte ê Resistência,” a major concert in the famed 19th century opera house Teatro Amazonas, concluded the trip on March 31. The packed event featured the MIT Wind Ensemble, MIT Festival Jazz Ensemble, MIT Vocal Jazz Ensemble, vocalist Luciana Souza, clarinetist Anat Cohen, MIT professor and composer-clarinetist Evan Ziporyn, and local musicians from Manaus. The program ended with “Nós Somos A Floresta (We Are The Forest) — Eware (Sacred Land) — Reflections on Amazonia,” a large-scale collaborative performance with Djuena Tikuna. The two songs were composed by Tikuna, with Eware newly arranged by Israeli composer-bassist Nadav Erlich for the occasion. It concluded with all musicians and audience members coming together in song: a moving and beautiful moment of mediation on the sacredness of the earth.

      “It was humbling to see the grand display of beauty and diversity that nature developed in the Amazon rainforest,” reflects bass clarinetist and MIT sophomore Richard Chen. “By seeing the bird life, sloths, and other species and the flora, and eating the fruits of the region, I received lessons on my harmony and connection to the natural world around us. I developed a deeper awareness of the urgency of resolving conflicts and stopping the destruction of the Amazon rainforest, and to listening to and celebrating the stories and experiences of those around me.”

      Indigenous musicians embodying the natural world

      “The trip expanded the scope of what music means,” MIT Vocal Jazz Ensemble member and biomedical researcher Autumn Geil explains. “It’s living the music, and you can’t feel that unless you put yourself in new experiences and get yourself out of your comfort zone.”

      Over two Indigenous music immersion days, students spent time listening to, and playing and singing with, musicians who broadened their scope of music’s relationship to nature and cultural sustainability. Indigenous percussionist and instrument builder Eliberto Barroncas and music producer-arranger César Lima presented contrasting approaches with a shared objective — connecting people to the natural world through Indigenous instruments.

      Barroncas played instruments built from materials from the rainforest and from found objects in Manaus that others might consider trash, creating ethereal tones bespeaking his life as one with nature. Students had the opportunity to play his instruments and create a spontaneous composition playing their own instruments and singing with him in a kind of “Amazonia jam session.”

      “Eliberto expressed that making music is visceral; it’s best when it comes from the gut and is tangible and coming from one’s natural environment. When we cannot understand each other using language, using words, logic and thinking, we go back to the body,” notes oboist and ocean engineer Michelle Kornberg ’20. “There’s a difference between teaching music as a skill you learn and teaching music as something you feel, that you experience and give — as a gift.”

      Over the pandemic, César Lima developed an app, “The Roots VR,” as a vehicle for people to discover over 100 Amazonia instruments. Users choose settings to interact with instruments and create pieces using a variety of instrumental combinations; a novel melding of technology with nature to expand the reach of these Indigenous instruments and their cultural significance.

      At the Cultural Center of the Peoples of the Amazon, students gathered around a tree, hand-in-hand singing with Djuena Tikuna, accompanied by percussionist Diego Janatã. “She spoke about being one of the first Indigenous musicians ever to sing in the Teatro Amazonas, which was built on the labor and blood of Indigenous people,” recalls flutist and atmospheric engineer Phoebe Lin, an MIT junior. “And then to hold hands and close our eyes and step back and forth; a rare moment of connection in a tumultuous world — it felt like we were all one.”

      Bringing the forest back to MIT

      On April 29, Djuena Tikuna made her MIT debut at “We Are the Forest — Music of Resilience and Activism,” a special concert for MIT President Sally Kornbluth’s inauguration, presenting music from the Teatro Amazonas event. Led and curated by Harris, the performance included new assistant professor in jazz and saxophonist-composer Miguel Zenón, director of the MIT Vocal Jazz Ensemble; Laura Grill Jaye; and vocalist Sara Serpa, among others. 

      “Music unites people and through art we can draw the world’s attention to the most urgent global challenges such as climate change,” says Djuena Tikuna. “My songs bring the message that every seed will one day germinate to reforest hearts, because we are all from the same village.”

      Hearing Amazônia has set the stage for the blossoming of artistic and scientific collaborations in the Amazon and beyond.

      “The struggle of Indigenous peoples to keep their territories alive should concern us all, and it will take more than science and research to help find solutions for climate change,” notes President Kornbluth. “It will take artists, too, to unite us and raise awareness across all communities. The inclusivity and expressive power of music can help get us all rowing in the same direction — it’s a great way to encourage us all to care and act!” More

      Accelerated climate action needed to sharply reduce current risks to life and life-support systems

      by

      Hottest day on record. Hottest month on record. Extreme marine heatwaves. Record-low Antarctic sea-ice.

      While El Niño is a short-term factor in this year’s record-breaking heat, human-caused climate change is the long-term driver. And as global warming edges closer to 1.5 degrees Celsius — the aspirational upper limit set in the Paris Agreement in 2015 — ushering in more intense and frequent heatwaves, floods, wildfires, and other climate extremes much sooner than many expected, current greenhouse gas emissions-reduction policies are far too weak to keep the planet from exceeding that threshold. In fact, on roughly one-third of days in 2023, the average global temperature was at least 1.5 C higher than pre-industrial levels. Faster and bolder action will be needed — from the in-progress United Nations Climate Change Conference (COP28) and beyond — to stabilize the climate and minimize risks to human (and nonhuman) lives and the life-support systems (e.g., food, water, shelter, and more) upon which they depend.

      Quantifying the risks posed by simply maintaining existing climate policies — and the benefits (i.e., avoided damages and costs) of accelerated climate action aligned with the 1.5 C goal — is the central task of the 2023 Global Change Outlook, recently released by the MIT Joint Program on the Science and Policy of Global Change.

      Based on a rigorous, integrated analysis of population and economic growth, technological change, Paris Agreement emissions-reduction pledges (Nationally Determined Contributions, or NDCs), geopolitical tensions, and other factors, the report presents the MIT Joint Program’s latest projections for the future of the earth’s energy, food, water, and climate systems, as well as prospects for achieving the Paris Agreement’s short- and long-term climate goals.

      The 2023 Global Change Outlook performs its risk-benefit analysis by focusing on two scenarios. The first, Current Trends, assumes that Paris Agreement NDCs are implemented through the year 2030, and maintained thereafter. While this scenario represents an unprecedented global commitment to limit greenhouse gas emissions, it neither stabilizes climate nor limits climate change. The second scenario, Accelerated Actions, extends from the Paris Agreement’s initial NDCs and aligns with its long-term goals. This scenario aims to limit and stabilize human-induced global climate warming to 1.5 C by the end of this century with at least a 50 percent probability. Uncertainty is quantified using 400-member ensembles of projections for each scenario.

      This year’s report also includes a visualization tool that enables a higher-resolution exploration of both scenarios.

      Energy

      Between 2020 and 2050, population and economic growth are projected to drive continued increases in energy needs and electrification. Successful achievement of current Paris Agreement pledges will reinforce a shift away from fossil fuels, but additional actions will be required to accelerate the energy transition needed to cap global warming at 1.5 C by 2100.

      During this 30-year period under the Current Trends scenario, the share of fossil fuels in the global energy mix drops from 80 percent to 70 percent. Variable renewable energy (wind and solar) is the fastest growing energy source with more than an 8.6-fold increase. In the Accelerated Actions scenario, the share of low-carbon energy sources grows from 20 percent to slightly more than 60 percent, a much faster growth rate than in the Current Trends scenario; wind and solar energy undergo more than a 13.3-fold increase.

      While the electric power sector is expected to successfully scale up (with electricity production increasing by 73 percent under Current Trends, and 87 percent under Accelerated Actions) to accommodate increased demand (particularly for variable renewables), other sectors face stiffer challenges in their efforts to decarbonize.

      “Due to a sizeable need for hydrocarbons in the form of liquid and gaseous fuels for sectors such as heavy-duty long-distance transport, high-temperature industrial heat, agriculture, and chemical production, hydrogen-based fuels and renewable natural gas remain attractive options, but the challenges related to their scaling opportunities and costs must be resolved,” says MIT Joint Program Deputy Director Sergey Paltsev, a lead author of the 2023 Global Change Outlook.

      Water, food, and land

      With a global population projected to reach 9.9 billion by 2050, the Current Trends scenario indicates that more than half of the world’s population will experience pressures to its water supply, and that three of every 10 people will live in water basins where compounding societal and environmental pressures on water resources will be experienced. Population projections under combined water stress in all scenarios reveal that the Accelerated Actions scenario can reduce approximately 40 million of the additional 570 million people living in water-stressed basins at mid-century.

      Under the Current Trends scenario, agriculture and food production will keep growing. This will increase pressure for land-use change, water use, and use of energy-intensive inputs, which will also lead to higher greenhouse gas emissions. Under the Accelerated Actions scenario, less agricultural and food output is observed by 2050 compared to the Current Trends scenario, since this scenario affects economic growth and increases production costs. Livestock production is more greenhouse gas emissions-intensive than crop and food production, which, under carbon-pricing policies, drives demand downward and increases costs and prices. Such impacts are transmitted to the food sector and imply lower consumption of livestock-based products.

      Land-use changes in the Accelerated Actions scenario are similar to those in the Current Trends scenario by 2050, except for land dedicated to bioenergy production. At the world level, the Accelerated Actions scenario requires cropland area to increase by 1 percent and pastureland to decrease by 4.2 percent, but land use for bioenergy must increase by 44 percent.

      Climate trends

      Under the Current Trends scenario, the world is likely (more than 50 percent probability) to exceed 2 C global climate warming by 2060, 2.8 C by 2100, and 3.8 C by 2150. Our latest climate-model information indicates that maximum temperatures will likely outpace mean temperature trends over much of North and South America, Europe, northern and southeast Asia, and southern parts of Africa and Australasia. So as human-forced climate warming intensifies, these regions are expected to experience more pronounced record-breaking extreme heat events.

      Under the Accelerated Actions scenario, global temperature will continue to rise through the next two decades. But by 2050, global temperature will stabilize, and then slightly decline through the latter half of the century.

      “By 2100, the Accelerated Actions scenario indicates that the world can be virtually assured of remaining below 2 C of global warming,” says MIT Joint Program Deputy Director C. Adam Schlosser, a lead author of the report. “Nevertheless, additional policy mechanisms must be designed with more comprehensive targets that also support a cleaner environment, sustainable resources, as well as improved and equitable human health.”

      The Accelerated Actions scenario not only stabilizes global precipitation increase (by 2060), but substantially reduces the magnitude and potential range of increases to almost one-third of Current Trends global precipitation changes. Any global increase in precipitation heightens flood risk worldwide, so policies aligned with the Accelerated Actions scenario would considerably reduce that risk.

      Prospects for meeting Paris Agreement climate goals

      Numerous countries and regions are progressing in fulfilling their Paris Agreement pledges. Many have declared more ambitious greenhouse gas emissions-mitigation goals, while financing to assist the least-developed countries in sustainable development is not forthcoming at the levels needed. In this year’s Global Stocktake Synthesis Report, the U.N. Framework Convention on Climate Change evaluated emissions reductions communicated by the parties of the Paris Agreement and concluded that global emissions are not on track to fulfill the most ambitious long-term global temperature goals of the Paris Agreement (to keep warming well below 2 C — and, ideally, 1.5 C — above pre-industrial levels), and there is a rapidly narrowing window to raise ambition and implement existing commitments in order to achieve those targets. The Current Trends scenario arrives at the same conclusion.

      The 2023 Global Change Outlook finds that both global temperature targets remain achievable, but require much deeper near-term emissions reductions than those embodied in current NDCs.

      Reducing climate risk

      This report explores two well-known sets of risks posed by climate change. Research highlighted indicates that elevated climate-related physical risks will continue to evolve by mid-century, along with heightened transition risks that arise from shifts in the political, technological, social, and economic landscapes that are likely to occur during the transition to a low-carbon economy.

      “Our Outlook shows that without aggressive actions the world will surpass critical greenhouse gas concentration thresholds and climate targets in the coming decades,” says MIT Joint Program Director Ronald Prinn. “While the costs of inaction are getting higher, the costs of action are more manageable.” More

      Ayomikun Ayodeji ’22 named a 2024 Rhodes Scholar

      by

      Ayomikun “Ayo” Ayodeji ’22 from Lagos, Nigeria, has been selected as a Rhodes Scholar for West Africa. He will begin fully funded postgraduate studies at Oxford University in the U.K. next fall.

      Ayodeji was supported by Associate Dean Kim Benard and the Distinguished Fellowships team in Career Advising and Professional Development, and received additional mentorship from the Presidential Committee on Distinguished Fellowships.

      “Ayo has worked hard to develop his vision and to express it in ways that will capture the imagination of the broader world. It is a thrill to see him recognized this year as a Rhodes Scholar,” says Professor Nancy Kanwisher, who co-chairs the committee along with Professor Will Broadhead.

      Ayodeji graduated from MIT in 2022 with BS degrees in chemical engineering and management. He is currently an associate at Boston Consulting Group.

      He is passionate about championing reliable energy access across the African landscape and fostering culturally inclusive communities. As a Rhodes Scholar, he will pursue an MSc in energy systems and an MSc in global governance and diplomacy.

      During his time at MIT, Ayodeji’s curiosity for energy innovations was fueled by his research on perovskite solar cells under the MIT Energy Initiative. He then went on to intern at Pioneer Natural Resources where he explored the boundless applications of machine learning tools in completions. At BCG, Ayodeji supports both public and private sector clients on a variety of renewable energy topics including clean energy transition, decarbonization roadmaps, and workforce development.

      Ayodeji’s community-oriented mindset led him to team up with a group of friends and partner with the Northeast Children’s Trust (NECT), an organization that helps children affected by the Boko Haram insurgency in northeastern Nigeria.

      MIT startup has big plans to pull carbon from the air

      by

      In order to avoid the worst effects of climate change, the United Nations has said we’ll need to not only reduce emissions but also remove carbon dioxide from the atmosphere. One method for achieving carbon removal is direct air capture and storage. Such technologies are still in their infancy, but many efforts are underway to scale them up quickly in hopes of heading off the most catastrophic effects of climate change.

      The startup Noya, founded by Josh Santos ’14, is working to accelerate direct-air carbon removal with a low-power, modular system that can be mass manufactured and deployed around the world. The company plans to power its system with renewable energy and build its facilities near injection wells to store carbon underground.

      Using third-party auditors to verify the amount of carbon dioxide captured and stored, Noya is selling carbon credits to help organizations reach net-zero emissions targets.

      “Think of our systems for direct air capture like solar panels for carbon negativity,” says Santos, who formerly played a role in Tesla’s much-publicized manufacturing scale-up for its Model 3 electric sedan. “We can stack these boxes in a LEGO-like fashion to achieve scale in the field.”

      The three-year old company is currently building its first commercial pilot facility, and says its first full-scale commercial facility will have the capacity to pull millions of tons of carbon from the air each year. Noya has already secured millions of dollars in presales to help build its first facilities from organizations including Shopify, Watershed, and a university endowment.

      Santos says the ambitious approach, which is driven by the urgent need to scale carbon removal solutions, was influenced by his time at MIT.

      “I need to thank all of my MIT professors,” Santos says. “I don’t think any of this would be possible without the way in which MIT opened up my horizons by showing me what’s possible when you work really hard.”

      Finding a purpose

      Growing up in the southeastern U.S., Santos says he first recognized climate change as an issue by experiencing the increasing intensity of hurricanes in his neighborhood. One year a hurricane forced his family to evacuate their town. When they returned, their church was gone.

      “The storm left a really big mark on me and how I thought about the world,” Santos says. “I realized how much climate change can impact people.”

      When Santos came to MIT as an undergraduate, he took coursework related to climate change and energy systems, eventually majoring in chemical engineering. He also learned about startups through courses he took at the MIT Sloan School of Management and by taking part in MIT’s Undergraduate Research Opportunities Program (UROP), which exposed him to researchers in the early stages of commercializing research from MIT labs.

      More than the coursework, though, Santos says MIT instilled in him a desire to make a positive impact on the world, in part through a four-day development workshop called LeaderShape that he took one January during the Institute’s Independent Activities Period (IAP).

      “LeaderShape teaches students how to lead with integrity, and the core lesson is that any privilege you have you should try to leverage to improve the lives of other people,” Santos says. “That really stuck with me. Going to MIT is a huge privilege, and it makes me feel like I have a responsibility to put that privilege to work to the betterment of society. It shaped a lot of how I view my career.”

      After graduation, Santos worked at Tesla, then at Harley Davidson, where he worked on electric powertrains. Eventually he decided electric vehicle technology couldn’t solve climate change on its own, so in the spring of 2020 he founded Noya with friend Daniel Cavaro.

      The initial idea for Noya was to attach carbon capture devices to cooling towers to keep equipment costs low. The founders pivoted in response to the passage of the Inflation Reduction Act in 2022 because their machines weren’t big enough to qualify for the new tax credits in the law, which required each system to capture at least 1,000 tons of CO2 per year.

      Noya’s new systems will combine thousands of its modular units to create massive facilities that can capture millions of tons of CO2 right next to existing injection wells.

      Each of Noya’s units is about the size of a solar panel at about 6 feet wide, 4.5 feet tall, and 1 foot thick. A fan blows air through tiny channels in each unit that contain Noya’s carbon capture material. The company’s material solution consists of an activated carbon monolith and a proprietary chemical feedstock that binds to the carbon in the air. When the material becomes saturated with carbon, electricity is applied to the material and a light vacuum collects a pure stream of carbon.

      The goal is for each of Noya’s modules to remove about 60 tons of CO2 from the atmosphere per year.

      “Other direct air capture companies need a big hot piece of equipment — like an oven, steam generator, or kiln — that takes electricity and converts it to get heat to the material,” Santos says. “Any lost heat into the surrounding environment is excess cost. We skip the need for the excess equipment and their inefficiencies by adding the electricity directly to the material itself.”

      Scaling with urgency

      From its office in Oakland, California, Noya is putting an experimental module through tests to optimize its design. Noya will launch its first testing facility, which should remove about 350 tons of CO2 per year, in 2024. It has already secured renewable energy and injection storage partners for that facility. Over the next few years Noya plans to capture and remove thousands of tons of CO2, and the company’s first commercial-scale facility will aim to remove about 3 million tons of carbon annually.

      “That design is what we’ll replicate across the world to grow our planetary impact,” Santos says. “We’re trying to scale up as fast as possible.”

      Noya has already sold all of the carbon credits it expects to generate in its first five years, and the founders believe the growing demand from companies and governments to purchase high-quality carbon credits will outstrip supply for at least the next 10 years in the nascent carbon removal industry, which also includes approaches like enhanced rock weathering, biomass carbon storage, and ocean alkalinity enhancement.

      “We’re going to need something like 30 companies the size of Shell to achieve the scale we need,” Santos says. “I think there will be large companies in each of those verticals. We’re in the early innings here.”

      Santos believes the carbon removal market can scale without government mandates, but he also sees increasing government and public support for carbon removal technologies around the world.

      “Carbon removal is a waste management problem,” Santos says. “You can’t just throw trash in the middle of the street. The way we currently deal with trash is polluters pay to clean up their waste. Carbon removal should be like that. CO2 is a waste product, and we should have regulations in place that are requiring polluters, like businesses, to clean up their waste emissions. It’s a public good to provide cleaner air.” More

      How to tackle the global deforestation crisis

      by

      Imagine if France, Germany, and Spain were completely blanketed in forests — and then all those trees were quickly chopped down. That’s nearly the amount of deforestation that occurred globally between 2001 and 2020, with profound consequences.

      Deforestation is a major contributor to climate change, producing between 6 and 17 percent of global greenhouse gas emissions, according to a 2009 study. Meanwhile, because trees also absorb carbon dioxide, removing it from the atmosphere, they help keep the Earth cooler. And climate change aside, forests protect biodiversity.

      “Climate change and biodiversity make this a global problem, not a local problem,” says MIT economist Ben Olken. “Deciding to cut down trees or not has huge implications for the world.”

      But deforestation is often financially profitable, so it continues at a rapid rate. Researchers can now measure this trend closely: In the last quarter-century, satellite-based technology has led to a paradigm change in charting deforestation. New deforestation datasets, based on the Landsat satellites, for instance, track forest change since 2000 with resolution at 30 meters, while many other products now offer frequent imaging at close resolution.

      “Part of this revolution in measurement is accuracy, and the other part is coverage,” says Clare Balboni, an assistant professor of economics at the London School of Economics (LSE). “On-site observation is very expensive and logistically challenging, and you’re talking about case studies. These satellite-based data sets just open up opportunities to see deforestation at scale, systematically, across the globe.”

      Balboni and Olken have now helped write a new paper providing a road map for thinking about this crisis. The open-access article, “The Economics of Tropical Deforestation,” appears this month in the Annual Review of Economics. The co-authors are Balboni, a former MIT faculty member; Aaron Berman, a PhD candidate in MIT’s Department of Economics; Robin Burgess, an LSE professor; and Olken, MIT’s Jane Berkowitz Carlton and Dennis William Carlton Professor of Microeconomics. Balboni and Olken have also conducted primary research in this area, along with Burgess.

      So, how can the world tackle deforestation? It starts with understanding the problem.

      Replacing forests with farms

      Several decades ago, some thinkers, including the famous MIT economist Paul Samuelson in the 1970s, built models to study forests as a renewable resource; Samuelson calculated the “maximum sustained yield” at which a forest could be cleared while being regrown. These frameworks were designed to think about tree farms or the U.S. national forest system, where a fraction of trees would be cut each year, and then new trees would be grown over time to take their place.

      But deforestation today, particularly in tropical areas, often looks very different, and forest regeneration is not common.

      Indeed, as Balboni and Olken emphasize, deforestation is now rampant partly because the profits from chopping down trees come not just from timber, but from replacing forests with agriculture. In Brazil, deforestation has increased along with agricultural prices; in Indonesia, clearing trees accelerated as the global price of palm oil went up, leading companies to replace forests with palm tree orchards.

      All this tree-clearing creates a familiar situation: The globally shared costs of climate change from deforestation are “externalities,” as economists say, imposed on everyone else by the people removing forest land. It is akin to a company that pollutes into a river, affecting the water quality of residents.

      “Economics has changed the way it thinks about this over the last 50 years, and two things are central,” Olken says. “The relevance of global externalities is very important, and the conceptualization of alternate land uses is very important.” This also means traditional forest-management guidance about regrowth is not enough. With the economic dynamics in mind, which policies might work, and why?

      The search for solutions

      As Balboni and Olken note, economists often recommend “Pigouvian” taxes (named after the British economist Arthur Pigou) in these cases, levied against people imposing externalities on others. And yet, it can be hard to identify who is doing the deforesting.

      Instead of taxing people for clearing forests, governments can pay people to keep forests intact. The UN uses Payments for Environmental Services (PES) as part of its REDD+ (Reducing Emissions from Deforestation and forest Degradation) program. However, it is similarly tough to identify the optimal landowners to subsidize, and these payments may not match the quick cash-in of deforestation. A 2017 study in Uganda showed PES reduced deforestation somewhat; a 2022 study in Indonesia found no reduction; another 2022 study, in Brazil, showed again that some forest protection resulted.

      “There’s mixed evidence from many of these [studies],” Balboni says. These policies, she notes, must reach people who would otherwise clear forests, and a key question is, “How can we assess their success compared to what would have happened anyway?”

      Some places have tried cash transfer programs for larger populations. In Indonesia, a 2020 study found such subsidies reduced deforestation near villages by 30 percent. But in Mexico, a similar program meant more people could afford milk and meat, again creating demand for more agriculture and thus leading to more forest-clearing.

      At this point, it might seem that laws simply banning deforestation in key areas would work best — indeed, about 16 percent of the world’s land overall is protected in some way. Yet the dynamics of protection are tricky. Even with protected areas in place, there is still “leakage” of deforestation into other regions. 

      Still more approaches exist, including “nonstate agreements,” such as the Amazon Soy Moratorium in Brazil, in which grain traders pledged not to buy soy from deforested lands, and reduced deforestation without “leakage.”

      Also, intriguingly, a 2008 policy change in the Brazilian Amazon made agricultural credit harder to obtain by requiring recipients to comply with environmental and land registration rules. The result? Deforestation dropped by up to 60 percent over nearly a decade. 

      Politics and pulp

      Overall, Balboni and Olken observe, beyond “externalities,” two major challenges exist. One, it is often unclear who holds property rights in forests. In these circumstances, deforestation seems to increase. Two, deforestation is subject to political battles.

      For instance, as economist Bard Harstad of Stanford University has observed, environmental lobbying is asymmetric. Balboni and Olken write: “The conservationist lobby must pay the government in perpetuity … while the deforestation-oriented lobby need pay only once to deforest in the present.” And political instability leads to more deforestation because “the current administration places lower value on future conservation payments.”

      Even so, national political measures can work. In the Amazon from 2001 to 2005, Brazilian deforestation rates were three to four times higher than on similar land across the border, but that imbalance vanished once the country passed conservation measures in 2006. However, deforestation ramped up again after a 2014 change in government. Looking at particular monitoring approaches, a study of Brazil’s satellite-based Real-Time System for Detection of Deforestation (DETER), launched in 2004, suggests that a 50 percent annual increase in its use in municipalities created a 25 percent reduction in deforestation from 2006 to 2016.

      How precisely politics matters may depend on the context. In a 2021 paper, Balboni and Olken (with three colleagues) found that deforestation actually decreased around elections in Indonesia. Conversely, in Brazil, one study found that deforestation rates were 8 to 10 percent higher where mayors were running for re-election between 2002 and 2012, suggesting incumbents had deforestation industry support.

      “The research there is aiming to understand what the political economy drivers are,” Olken says, “with the idea that if you understand those things, reform in those countries is more likely.”

      Looking ahead, Balboni and Olken also suggest that new research estimating the value of intact forest land intact could influence public debates. And while many scholars have studied deforestation in Brazil and Indonesia, fewer have examined the Democratic Republic of Congo, another deforestation leader, and sub-Saharan Africa.

      Deforestation is an ongoing crisis. But thanks to satellites and many recent studies, experts know vastly more about the problem than they did a decade or two ago, and with an economics toolkit, can evaluate the incentives and dynamics at play.

      “To the extent that there’s ambuiguity across different contexts with different findings, part of the point of our review piece is to draw out common themes — the important considerations in determining which policy levers can [work] in different circumstances,” Balboni says. “That’s a fast-evolving area. We don’t have all the answers, but part of the process is bringing together growing evidence about [everything] that affects how successful those choices can be.” 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: A high-tech take on Wagner’s “Parsifal” opera

      by

      The world-famous Bayreuth Festival in Germany, annually centered around the works of composer Richard Wagner, launched this summer on July 25 with a production that has been making headlines. Director Jay Scheib, an MIT faculty member, has created a version of Wagner’s celebrated opera “Parsifal” that is set in an apocalyptic future (rather than the original Medieval past), and uses augmented reality headset technology for a portion of the audience, among other visual effects. People using the headsets see hundreds of additional visuals, from fast-moving clouds to arrows being shot at them. The AR portion of the production was developed through a team led by designer and MIT Technical Instructor Joshua Higgason.

      The new “Parsifal” has engendered extensive media attention and discussion among opera followers and the viewing public. Five years in the making, it was developed with the encouragement of Bayreuth Festival general manager Katharina Wagner, Richard Wagner’s great-granddaughter. The production runs until Aug. 27, and can also be streamed on Stage+. Scheib, the Class of 1949 Professor in MIT’s Music and Theater Arts program, recently talked to MIT News about the project from Bayreuth.

      Q: Your production of “Parsifal” led off this year’s entire Bayreuth festival. How’s it going?

      A: From my point of view it’s going quite swimmingly. The leading German opera critics and the audiences have been super-supportive and Bayreuth makes it possible for a work to evolve … Given the complexity of the technical challenge of making an AR project function in an opera house, the bar was so high, it was a difficult challenge, and we’re really happy we found a way forward, a way to make it work, and a way to make it fit into an artistic process. I feel great.

      Q: You offer a new interpretation of “Parsifal,” and a new setting for it. What is it, and why did you choose to interpret it this way?

      A: One of the main themes in “Parsifal” is that the long-time king of this holy grail cult is wounded, and his wound will not heal. [With that in mind], we looked at what the world was like when the opera premiered in the late 19th century, around the time of what was known as the Great African Scramble, when Europe re-drew the map of Africa, largely based on resources, including mineral resources.

      Cobalt remains [the focus of] dirty mining practices in the Democratic Republic of Congo, and is a requirement for a lot of our electronic objects, in particular batteries. There are also these massive copper deposits discovered under a Buddhist temple in Afghanistan, and lithium under a sacred site in Nevada. We face an intense challenge in climate change, and the predictions are not good. Some of our solutions like electric cars require these materials, so they’re only solutions for some people, while others suffer [where minerals are being mined]. We started thinking about how wounds never heal, and when the prospect of creating a better world opens new wounds in other communities. … That became a theme. It also comes out of the time when we were making it, when Covid happened and George Floyd was murdered, which created an opportunity in the U.S. to start speaking very openly about wounds that have not healed.

      We set it in a largely post-human environment, where we didn’t succeed, and everything has collapsed. In the third act, there’s derelict mining equipment, and the holy water is this energy-giving force, but in fact it’s this lithium-ion pool, which gives us energy and then poisons us. That’s the theme we created.

      Q: What were your goals about integrating the AR technology into the opera, and how did you achieve that?

      A: First, I was working with my collaborator Joshua Higgason. No one had ever really done this before, so we just started researching whether it was possible. And most of the people we talked to said, “Don’t do it. It’s just not going to work.” Having always been a daredevil at heart, I was like, “Oh, come on, we can figure this out.”

      We were diligent in exploring the possibilities. We made multiple trips to Bayreuth and made these milimeter-accurate laser scans of the auditorium and the stage. We built a variety of models to see how to make AR work in a large environment, where 2,000 headsets could respond simultaneously. We built a team of animators and developers and programmers and designers, from Portugal to Cambridge to New York to Hungary, the UK, and a group in Germany. Josh led this team, and they got after it, but it took us the better part of two years to make it possible for an audience, some of whom don’t really use smartphones, to put on an AR headset and have it just work.

      I can’t even believe we did this. But it’s working.

      Q: In opera there’s hopefully a productive tension between tradition and innovation. How do you think about that when it comes to Wagner at Bayreuth?

      A: Innovation is the tradition at Bayreuth. Musically and scenographically. “Parsifal” was composed for this particular opera house, and I’m incredibly respectful of what this event is made for. We are trying to create a balanced and unified experience, between the scenic design and the AR and the lighting and the costume design, and create perfect moments of convergence where you really lose yourself in the environment. I believe wholly in the production and the performers are extraordinary. Truly, truly, truly extraordinary.

      Q: People have been focused on the issue of bringing AR to Bayreuth, but what has Bayreuth brought to you as a director?

      A: Working in Bayreuth has been an incredible experience. The level of intellectual integrity among the technicians is extraordinary. The amount of care and patience and curiosity and expertise in Bayreuth is off the charts. This community of artists is the greatest. … People come here because it’s an incredible meeting of the minds, and for that I’m immensely filled with gratitude every day I come into the rehearsal room. The conductor, Pablo Heras-Casado, and I have been working on this for several years. And the music is still first. We’re setting up technology not to overtake the music, but to support it, and visually amplify it.

      It must be said that Katharina Wagner has been one of the most powerfully supportive artistic directors I have ever worked with. I find it inspiring to witness her tenacity and vision in seeing all of this through, despite the hurdles. It’s been a great collaboration. That’s the essence: great collaboration. More
