News Feed
Monday, August 5, 2024

The MIT School of Science is launching a center to advance knowledge and computational capabilities in the field of sustainability science, and support decision-makers in government, industry, and civil society to achieve sustainable development goals. Aligned with the Climate Project at MIT, researchers at the MIT Center for Sustainability Science and Strategy will develop and apply expertise from across the Institute to improve understanding of sustainability challenges, and thereby provide actionable knowledge and insight to inform strategies for improving human well-being for current and future generations.Noelle Selin, professor at MIT’s Institute for Data, Systems and Society and the Department of Earth, Atmospheric and Planetary Sciences, will serve as the center’s inaugural faculty director. C. Adam Schlosser and Sergey Paltsev, senior research scientists at MIT, will serve as deputy directors, with Anne Slinn as executive director.Incorporating and succeeding both the Center for Global Change Science and Joint Program on the Science and Policy of Global Change while adding new capabilities, the center aims to produce leading-edge research to help guide societal transitions toward a more sustainable future. Drawing on the long history of MIT’s efforts to address global change and its integrated environmental and human dimensions, the center is well-positioned to lead burgeoning global efforts to advance the field of sustainability science, which seeks to understand nature-society systems in their full complexity. This understanding is designed to be relevant and actionable for decision-makers in government, industry, and civil society in their efforts to develop viable pathways to improve quality of life for multiple stakeholders.“As critical challenges such as climate, health, energy, and food security increasingly affect people’s lives around the world, decision-makers need a better understanding of the earth in its full complexity — and that includes people, technologies, and institutions as well as environmental processes,” says Selin. “Better knowledge of these systems and how they interact can lead to more effective strategies that avoid unintended consequences and ensure an improved quality of life for all.”    Advancing knowledge, computational capability, and decision supportTo produce more precise and comprehensive knowledge of sustainability challenges and guide decision-makers to formulate more effective strategies, the center has set the following goals:Advance fundamental understanding of the complex interconnected physical and socio-economic systems that affect human well-being. As new policies and technologies are developed amid climate and other global changes, they interact with environmental processes and institutions in ways that can alter the earth’s critical life-support systems. Fundamental mechanisms that determine many of these systems’ behaviors, including those related to interacting climate, water, food, and socio-economic systems, remain largely unknown and poorly quantified. Better understanding can help society mitigate the risks of abrupt changes and “tipping points” in these systems.Develop, establish and disseminate new computational tools toward better understanding earth systems, including both environmental and human dimensions. The center’s work will integrate modeling and data analysis across disciplines in an era of increasing volumes of observational data. MIT multi-system models and data products will provide robust information to inform decision-making and shape the next generation of sustainability science and strategy.Produce actionable science that supports equity and justice within and across generations. The center’s research will be designed to inform action associated with measurable outcomes aligned with supporting human well-being across generations. This requires engaging a broad range of stakeholders, including not only nations and companies, but also nongovernmental organizations and communities that take action to promote sustainable development — with special attention to those who have historically borne the brunt of environmental injustice.“The center’s work will advance fundamental understanding in sustainability science, leverage leading-edge computing and data, and promote engagement and impact,” says Selin. “Our researchers will help lead scientists and strategists across the globe who share MIT’s commitment to mobilizing knowledge to inform action toward a more sustainable world.”Building a better world at MITBuilding on existing MIT capabilities in sustainability, science, and strategy, the center aims to: focus research, education, and outreach under a theme that reflects a comprehensive state of the field and international research directions, fostering a dynamic community of students, researchers, and faculty;raise the visibility of sustainability science at MIT, emphasizing links between science and action, in the context of existing Institute goals and other efforts on climate and sustainability, and in a way that reflects the vital contributions of a range of natural and social science disciplines to understanding human-environment systems; andre-emphasize MIT’s long-standing expertise in integrated systems modeling while leveraging the Institute’s concurrent leading-edge strengths in data and computing, establishing leadership that harnesses recent innovations, including those in machine learning and artificial intelligence, toward addressing the science challenges of global change and sustainability.“The Center for Sustainability Science and Strategy will provide the necessary synergy for our MIT researchers to develop, deploy, and scale up serious solutions to climate change and other critical sustainability challenges,” says Nergis Mavalvala the Curtis and Kathleen Marble Professor of Astrophysics and dean of the MIT School of Science. “With Professor Selin at its helm, the center will also ensure that these solutions are created in concert with the people who are directly affected now and in the future.”The center builds on more than three decades of achievements by the Center for Global Change Science and the Joint Program on the Science and Policy of Global Change, both of which were directed or co-directed by professor of atmospheric science Ronald Prinn.

New center taps Institute-wide expertise to improve understanding of, and responses to, sustainability challenges.

Here's What a SpaceX Starship Rocket Launch Sounds Like, According to New, Detailed Data

Just six miles away from the mega-rocket's fifth test flight, the noise level was equivalent to a rock concert, researchers found

The BYU research team at Boca Chica Beach, Texas. Logan Mathews On October 13th, SpaceX’s Starship spacecraft and its reusable booster Super Heavy launched from Boca Chica, Texas. In a world first, Super Heavy returned to the launch tower after separating from Starship and was caught by a pair of chopstick-like arms in a daring maneuver. That was Starship’s fifth test flight—and during the launch, researchers from Brigham Young University (BYU) were there to measure the event’s noise from start to finish. The results of their study were published in JASA Express Letters last week. “It was the loudest thing I’ve ever heard, for sure. You can feel the sound whipping over your body; it feels like it’s almost pushing you back sometimes,” study co-author Noah Pulsipher, a student in BYU’s Physics and Aerospace Student-Centered Acoustics Laboratory, says in a statement. “And then, all around me, car alarms are going off and dogs barking—things like that. It’s a powerful experience.” The study presents the most comprehensive sonic data on Starship ever released to the public, per the New York Times’ Eric Lipton. The team recorded measurements at eight locations, all within 6 to 22 miles of the launch site, including a hotel roof and national wildlife refuges. Starship is currently the world’s most powerful rocket, and its sound levels show it. One launch of this behemoth produces as much noise as at least ten of SpaceX’s Falcon 9 launches, per the statement. From just over six miles away, the noise was equivalent to a rock concert. At 12.4 miles, it was similar to a table saw or snow blower. Even at 18.6 to 21.7 miles away, it was still as loud as a vacuum cleaner. But the liftoff, when all 33 of Super Heavy’s engines fired, wasn’t even the loudest moment—sound peaked about 6.5 minutes after launch, when the booster returned to its launch tower and caused a sonic boom. The peak level of noise, measured at roughly six miles away, was as loud as a gunshot at close range, per the New York Times. The communities of South Padre Island and Port Isabel, which are around six miles from Starship’s launch site, are particularly impacted by the noise. A separate study conducted by Terracon Consultants analyzed the impact of sound waves on Port Isabel homes within five miles from Starship’s launch site from July to mid-October, per KRGV’s Christian von Preysing. The study shows that during that time, air pressure increased during the launches, and the sound pressure peaked at 144 decibels, though it specifies that the readings exceeded the sound meter’s limit. For comparison, windows can break at 150 decibels, and they begin rattling at 120 decibels, per KRGV. “What it shows is that, number one, that the impacts are real, that they are being felt by these structures,” Port Isabel City Manager Jared Hockema tells KRGV. He adds to the New York Times that some residents reported minor damage to their homes after Starship launches. BYU researchers set up acoustic instruments around the launch site to analyze sound levels from the rocket. Logan Mathews There are currently no regulations on rocket noise levels, per the statement, and the Federal Aviation Administration (FAA) and SpaceX did not respond to the New York Times’ requests for comment. The results of the BYU study “show that some sound metrics agree with those presented in the FAA’s most recent Environmental Assessment (EA) from 2024, while some predictions made by the EA are off,” writes Haygen Warren in a post for NASASpaceflight.com, which is not affiliated with NASA. Nevertheless, the researchers stress the importance of understanding how the launch noise impacts surrounding communities and environment, especially in light of SpaceX’s plans to increase its Starship launches to 100 per year. But the BYU team isn’t finished yet—they were also on site this week, analyzing acoustic data from Starship’s launch on Tuesday. During that test—the rocket’s sixth flight—Starship fired an engine in space in a key step forward and splashed down in the Indian Ocean. SpaceX chose to abort an attempt to catch the Super Heavy booster, however, which it had achieved last month on the first try. Get the latest stories in your inbox every weekday.

The heater’s cable is 72 inches in length, making this model a good choice for rooms with few outlets; plus, the unit includes a multifunction remote control for added convenience. What to consider when buying the best space heaters There are six things you should consider to find the best space heater for your needs. Think about what type of personal heater you want, how much space you’re trying to warm, how much power your heater will need, what the safety features are, and finally, what special features might be available. If you can get specific about your requirements, you won’t have any trouble finding a reliable, long-lasting unit you’re happy with. What type of space heater best fits your needs? There are three main types of heating, with a few subcategories you should know about. Convection heating is the most common and efficient type for single-room use. These space heaters work by circulating currents across an element, such as an electric coil or oil, which are often blown out and drawn back in using a fan. Some models don’t include a fan, relying on natural airflow; this method is quieter but takes longer to heat an entire room. Ceramic heaters borrow from this method, using an internal, self-regulating ceramic element and fan to heat a room quickly. Radiant heating is excellent for warming a targeted area like your bed or desk chair. They heat up almost instantaneously using quartz or other metals and a reflector to direct heat, though some will implement a fan. Infrared heaters are very similar, using infrared quartz bulbs to generate radiating heat. Unlike convection heating, this method will not warm up the air, making it better for targeted warmth. That said, it will heat a room if left on for a long time. Micathermic heating is an efficient combination of convection and radiant processes. A micathermic heater radiates warmth off of a panel that is then circulated naturally throughout the room. To do this, these space heaters need to be reasonably large, but most models can be mounted on the wall to save space if necessary. Because micathermic heaters don’t use a fan, they are quiet and clean; they don’t circulate dust or pet dander, which makes them great for those who are allergy-prone or have asthma. Portable radiator heaters use micathermic methods to generate heat via oil encased inside. How big of a room are you trying to heat? While it’s clear that radiant heaters are best for targeted use and convection or micathermic models might be best for larger areas, there’s more to understand when it comes to room size and heater specs. When it comes to heating, wattage is king. For space heaters, you want to have 10 watts of power per square foot; this is especially true if your portable heater is the primary source of warmth. If you have super tall ceilings, over 8 feet high, you’ll want to multiply your space’s total square footage by the ceiling height and 1.25. For rooms lacking insulation, add an extra 2 watts to the equation. If you just need a little extra blast of heat here and there, you can relax on the wattage rule, but only slightly. If you have a lot of ground to cover, it can be hard to find a supplementary heater that will keep you and any guests cozy for hours at a time. Infrared heaters are a bit more flexible because they warm up people and objects; while small models won’t do much, a large infrared heater can cover a larger room because it will target objects as well as people. Below you can find our favorite model. How much energy will your space heater use? Using a space heater regularly can suck up a lot of power, so it’s essential to look for energy-efficient models that won’t cause your electric bill to skyrocket. If you want to figure out how much your heater will cost you look up how much you currently pay for electricity per kilowatt-hour (this info is often listed on your monthly bill), determine the amount of time your space heater will be on, and calculate the kilowatts used per hour by dividing the maximum wattage by 1,000. Finally, multiply all three together, and that’s your average cost per day. Unfortunately, at this time, the United States Environmental Protection Agency hasn’t given any existing space heater an Energy Star rating, but that doesn’t mean you can’t look for models with energy-efficient features. First things first: Don’t buy a space heater that has more wattage than you need. Just because it’s powerful doesn’t mean it’s the best space heater for you. Oil-filled radiator heaters are a great option for energy-efficient heating in a tinier area because they remain hot for a time, even after they are turned off. Secondly, consider investing in a model that includes a built-in thermostat and multiple output settings. This will conserve energy over time because the heater won’t be overcompensating when the temperature in the room changes. Timed heat settings and automatic shutoff can also aid efficiency, especially if you tend to forget to shut off appliances. Some heaters will come with an auto-eco setting designed to monitor room temperature and suggest a lower output temperature to heat the room, keeping it warm but not hot. What extra features make the best space heater? Once you’ve figured out the size, specs, and safety settings you need to narrow down your selection, you can focus on the fun bonuses that make the best space heater. We’ve already mentioned a few helpful features, including a thermostat function, auto-eco mode, and timer settings. Another popular bonus feature is the inclusion of a remote for easy control. This is going to be a lifesaver for those times you get perfectly comfortable, all snuggled up in bed before remembering to turn the heater on. It gets better: Some space heaters are considered “smart,” which means they can connect via WiFi to your phone, providing a stream of information regarding your space’s air quality, humidity, and more. Some smart models come with a night-time mode to quiet noisy fans, HEPA filters for air purification, and dual-cooling systems that utilize the fan function, bypassing the heat generator. Of course, the more special features you tack on, the higher the price but depending on the frequency of use and overall efficiency of various models, you could end up saving money over time. Higher-quality products experience fewer breakdowns and don’t need to be replaced as often, plus who wouldn’t want to control their space heater using a voice assistant like Alexa? One step closer to building your fully equipped smart house. What safety features should you keep in mind? We cannot overstate how important safety features are when it comes to space heaters. These powerful appliances are one of the leading causes of house fires in America, and while we want you to be warm, we certainly don’t want you to be that warm. Luckily, newer models are frequently equipped with safety features that will keep you and your loved ones out of harm’s way. You need to select a model with a shutoff sensor triggered if the unit starts to overheat or tip over. This small but significant add-on is imperative to keep things safe. You should also consider purchasing a model with a long extension cord, even if you don’t think you’ll need it. Why? Space heaters need to be directly plugged into the wall; a long cord means you can easily resist the temptation to plug it into existing power strips or extension cords for “just a minute.” Consider a model that has a cool-to-the-touch outer layer or handle so you can avoid any accidental burns. Finally, look for certifications from the Underwriters Laboratory and Intertek Group for added reassurance that your model meets safety standards. While built-in features are important, there are also a few rules you’ll have to follow: as stated, never use power/extension cords to plug in your heater; never put one on a rug or elevated surface; unless specified otherwise, you won’t want to put a space heater near the kitchen or bathroom; and keep them out of reach/away from young kids or pets. What brand best suits your needs? There are some great brands out there dedicated to supplying safe space heaters worldwide, and we certainly have a few favorites. Vornado, Dyson, and De’Longhi are staples in the space heater game. Vornado has been around since 1930 and manufactures top-of-the-line space heaters, air purifiers, fans, humidifiers, and more. Likewise, Dyson was founded in 1991 by James Dyson and, today, not only manufactures high-end home staples—such as space heaters, washing machines, robot vacuums, and blowdryers—but also invests in research projects to improve medical equipment—such as ventilators, digital monitors, and electric vehicles. The Italian company De’Longhi was incorporated in 1950 and is known for excellence in design when it comes to small home appliances such as espresso machines, portable air conditioners, dehumidifiers, space heaters, and more. De’Longhi has been the recipient of multiple awards and certifications for its dedication to high-end engineering, design, and production. FAQs Q: How much do space heaters cost?

Graph-based AI model maps the future of innovation

An AI method developed by Professor Markus Buehler finds hidden links between science and art to suggest novel materials.

Imagine using artificial intelligence to compare two seemingly unrelated creations — biological tissue and Beethoven’s “Symphony No. 9.” At first glance, a living system and a musical masterpiece might appear to have no connection. However, a novel AI method developed by Markus J. Buehler, the McAfee Professor of Engineering and professor of civil and environmental engineering and mechanical engineering at MIT, bridges this gap, uncovering shared patterns of complexity and order.“By blending generative AI with graph-based computational tools, this approach reveals entirely new ideas, concepts, and designs that were previously unimaginable. We can accelerate scientific discovery by teaching generative AI to make novel predictions about never-before-seen ideas, concepts, and designs,” says Buehler.The open-access research, recently published in Machine Learning: Science and Technology, demonstrates an advanced AI method that integrates generative knowledge extraction, graph-based representation, and multimodal intelligent graph reasoning.The work uses graphs developed using methods inspired by category theory as a central mechanism to teach the model to understand symbolic relationships in science. Category theory, a branch of mathematics that deals with abstract structures and relationships between them, provides a framework for understanding and unifying diverse systems through a focus on objects and their interactions, rather than their specific content. In category theory, systems are viewed in terms of objects (which could be anything, from numbers to more abstract entities like structures or processes) and morphisms (arrows or functions that define the relationships between these objects). By using this approach, Buehler was able to teach the AI model to systematically reason over complex scientific concepts and behaviors. The symbolic relationships introduced through morphisms make it clear that the AI isn't simply drawing analogies, but is engaging in deeper reasoning that maps abstract structures across different domains.Buehler used this new method to analyze a collection of 1,000 scientific papers about biological materials and turned them into a knowledge map in the form of a graph. The graph revealed how different pieces of information are connected and was able to find groups of related ideas and key points that link many concepts together.“What’s really interesting is that the graph follows a scale-free nature, is highly connected, and can be used effectively for graph reasoning,” says Buehler. “In other words, we teach AI systems to think about graph-based data to help them build better world representations models and to enhance the ability to think and explore new ideas to enable discovery.”Researchers can use this framework to answer complex questions, find gaps in current knowledge, suggest new designs for materials, and predict how materials might behave, and link concepts that had never been connected before.The AI model found unexpected similarities between biological materials and “Symphony No. 9,” suggesting that both follow patterns of complexity. “Similar to how cells in biological materials interact in complex but organized ways to perform a function, Beethoven's 9th symphony arranges musical notes and themes to create a complex but coherent musical experience,” says Buehler.In another experiment, the graph-based AI model recommended creating a new biological material inspired by the abstract patterns found in Wassily Kandinsky’s painting, “Composition VII.” The AI suggested a new mycelium-based composite material. “The result of this material combines an innovative set of concepts that include a balance of chaos and order, adjustable property, porosity, mechanical strength, and complex patterned chemical functionality,” Buehler notes. By drawing inspiration from an abstract painting, the AI created a material that balances being strong and functional, while also being adaptable and capable of performing different roles. The application could lead to the development of innovative sustainable building materials, biodegradable alternatives to plastics, wearable technology, and even biomedical devices.With this advanced AI model, scientists can draw insights from music, art, and technology to analyze data from these fields to identify hidden patterns that could spark a world of innovative possibilities for material design, research, and even music or visual art.“Graph-based generative AI achieves a far higher degree of novelty, explorative of capacity and technical detail than conventional approaches, and establishes a widely useful framework for innovation by revealing hidden connections,” says Buehler. “This study not only contributes to the field of bio-inspired materials and mechanics, but also sets the stage for a future where interdisciplinary research powered by AI and knowledge graphs may become a tool of scientific and philosophical inquiry as we look to other future work.”

MIT to lead expansion of regional innovation network

National Science Foundation grant expected to help New England researchers translate discoveries to commercial technology.

The U.S. National Science Foundation (NSF) has selected MIT to lead a new Innovation Corps (I-Corps) Hub to support a partnership of eight New England universities committed to expanding science and technology entrepreneurship across the region, accelerating the translation of discoveries into new solutions that benefit society. NSF announced the five-year cooperative agreement of up to $15 million today.The NSF I-Corps Hub: New England Region is expected to launch on Jan. 1, 2025. The seven institutions initially collaborating with MIT include Brown University, Harvard University, Northeastern University, Tufts University, University of Maine, University of Massachusetts Amherst, and the University of New Hampshire.Established by the NSF in 2011, the I-Corps program provides scientists and engineers from any discipline with hands-on educational experiences to advance their research from lab to impact.  There are more than 50,000 STEM researchers at the nearly 100 universities and medical schools in New England. Many of these institutions are located in underserved and rural areas of the region that face resource challenges in supporting deep-tech translational efforts. The eight institutions in the hub will offer I-Corps training while bringing unique strengths and resources to enhance a regional innovation ecosystem that broadens participation in deep-tech innovation.“Now more than ever we need the innovative solutions that emerge from this type of collaboration to solve society’s greatest and most intractable challenges. Our collective sights are set on bolstering our regional and national innovation networks to accelerate the translation of fundamental research into commercialized technologies. MIT is eager to build on our ongoing work with NSF to further cultivate New England’s innovation hub,” says MIT Provost Cynthia Barnhart, the Abraham J. Siegel Professor of Management Science and professor of operations research, who is the principal investigator on the award.The hub builds on 10 years of collaboration with other I-Corps Sites at institutions across the region and prior work from the MIT I-Corps Site program launched in 2014 and the I-Corps Node based at MIT established in 2018. More than 3,000 engineers and scientists in New England have participated in regional I-Corps programs. They have formed over 200 companies, which have raised $3.5 billion in grants and investments. “The goal of the I-Corps program is to deploy experiential education to help researchers reduce the time necessary to translate promising ideas from laboratory benches to widespread implementation that in turn impacts economic growth regionally and nationally,” said Erwin Gianchandani, NSF assistant director for Technology, Innovation and Partnerships, in NSF’s announcement. “Each regional NSF I-Corps Hub provides training essential in entrepreneurship and customer discovery, leading to new products, startups, and jobs. In effect, we are investing in the next generation of entrepreneurs for our nation.”One I-Corps success story comes from Shreya Dave PhD ’16, who participated in I-Corps training in 2016 with her colleagues to explore potential applications for a new graphene oxide filter technology developed through her research. Based on their learnings from the program and the evidence collected, they shifted from filters for desalination to applications in chemical processing and gained the confidence to launch Via Separations in 2017, focused on the tough tech challenge of industrial decarbonization. Via Separations, which was co-founded by Morton and Claire Goulder and Family Professor in Environmental Systems Professor of Materials Science and Engineering Jeffrey Grossman and Chief Technical Officer Brent Keller, has reached commercialization and is now delivering products to the pulp and paper industry.“NSF I-Corps helped us refine our vision, figure out if our technology could be used for different applications, and helped us figure out if we can manufacture our technology in a scalable fashion — taking it from an academic project to a real–scale commercial project,” says Dave, who is the CEO and co-founder of Via Separations. New England boasts a “highly developed ecosystem of startup resources, funders, founders, and talent,” says Roman Lubynsky, executive director of MIT’s current NSF I-Corps Node, who will serve as the director of the new hub. “However, innovation and entrepreneurship support has been unevenly distributed across the region. This new hub offers an exciting opportunity to collaborate with seven partner institutions to extend and further scale up this important work throughout the region.”The I-Corps Hubs across the country form the backbone of the NSF National Innovation Network. This network connects universities, NSF researchers, entrepreneurs, regional communities, and federal agencies to help researchers bring their discoveries to the marketplace. Together, the hubs work to create a more inclusive and diverse innovation ecosystem, supporting researchers nationwide in transforming their ideas into real-world solutions.

3 Questions: The past, present, and future of sustainability science

Professor Ronald Prinn reflects on how far sustainability has come as a discipline, and where it all began at MIT.

It was 1978, over a decade before the word “sustainable” would infiltrate environmental nomenclature, and Ronald Prinn, MIT professor of atmospheric science, had just founded the Advanced Global Atmospheric Gases Experiment (AGAGE). Today, AGAGE provides real-time measurements for well over 50 environmentally harmful trace gases, enabling us to determine emissions at the country level, a key element in verifying national adherence to the Montreal Protocol and the Paris Accord. This, Prinn says, started him thinking about doing science that informed decision making.Much like global interest in sustainability, Prinn’s interest and involvement continued to grow into what would become three decades worth of achievements in sustainability science. The Center for Global Change Science (CGCS) and Joint Program on the Science and Policy Global Change, respectively founded and co-founded by Prinn, have recently joined forces to create the MIT School of Science’s new Center for Sustainability Science and Strategy (CS3), lead by former CGCS postdoc turned MIT professor, Noelle Selin.As he prepares to pass the torch, Prinn reflects on how far sustainability has come, and where it all began.Q: Tell us about the motivation for the MIT centers you helped to found around sustainability.A: In 1990 after I founded the Center for Global Change Science, I also co-founded the Joint Program on the Science and Policy Global Change with a very important partner, [Henry] “Jake” Jacoby. He’s now retired, but at that point he was a professor in the MIT Sloan School of Management. Together, we determined that in order to answer questions related to what we now call sustainability of human activities, you need to combine the natural and social sciences involved in these processes. Based on this, we decided to make a joint program between the CGCS and a center that he directed, the Center for Energy and Environmental Policy Research (CEEPR).It was called the “joint program” and was joint for two reasons — not only were two centers joining, but two disciplines were joining. It was not about simply doing the same science. It was about bringing a team of people together that could tackle these coupled issues of environment, human development and economy. We were the first group in the world to fully integrate these elements together.Q: What has been your most impactful contribution and what effect did it have on the greater public’s overall understanding?A: Our biggest contribution is the development, and more importantly, the application of the Integrated Global System Model [IGSM] framework, looking at human development in both developing countries and developed countries that had a significant impact on the way people thought about climate issues. With IGSM, we were able to look at the interactions among human and natural components, studying the feedbacks and impacts that climate change had on human systems; like how it would alter agriculture and other land activities, how it would alter things we derive from the ocean, and so on.Policies were being developed largely by economists or climate scientists working independently, and we started showing how the real answers and analysis required a coupling of all of these components. We showed, and I think convincingly, that what people used to study independently, must be coupled together, because the impacts of climate change and air pollution affected so many things.To address the value of policy, despite the uncertainty in climate projections, we ran multiple runs of the IGSM with and without policy, with different choices for uncertain IGSM variables. For public communication, around 2005, we introduced our signature Greenhouse Gamble interactive visualization tools; these have been renewed over time as science and policies evolved.Q: What can MIT provide now at this critical juncture in understanding climate change and its impact?A: We need to further push the boundaries of integrated global system modeling to ensure full sustainability of human activity and all of its beneficial dimensions, which is the exciting focus that the CS3 is designed to address. We need to focus on sustainability as a central core element and use it to not just analyze existing policies but to propose new ones. Sustainability is not just climate or air pollution, it's got to do with human impacts in general. Human health is central to sustainability, and equally important to equity. We need to expand the capability for credibly assessing what the impact policies have not just on developed countries, but on developing countries, taking into account that many places around the world are at artisanal levels of their economies. They cannot be blamed for anything that is changing climate and causing air pollution and other detrimental things that are currently going on. They need our help. That's what sustainability is in its full dimensions.Our capabilities are evolving toward a modeling system so detailed that we can find out detrimental things about policies even at local levels before investing in changing infrastructure. This is going to require collaboration among even more disciplines and creating a seamless connection between research and decision making; not just for policies enacted in the public sector, but also for decisions that are made in the private sector.

Salted Earth

"Salted Earth" plunges us into the heart of an invisible and creeping crisis that's transforming the Mid-Atlantic – the inexorable rise of sea levels. This hard-hitting, yet tenderly woven 20-minute documentary paints a vivid picture of an escalating environmental catastrophe, where the threat is not just the swelling sea, but the encroaching salt that kills forests and decimates arable land, but could also signal a return to the natural order of the Atlantic Coast. Our journey navigates the brackish waters of climate change alongside an intrepid team of scientists. Through their tireless work, they seek to unravel the intricacies of how salty water infiltrates groundwater and soils, with consequences as far-reaching as they are devastating. Their research is more than academic; it's a desperate quest for solutions that may help vulnerable communities adapt and even survive. "Salted Earth" is not only a saga of scientific discovery. It's also a story of human resilience and ingenuity. We venture into the heart of communities, the lifeblood of the Mid-Atlantic, whose existence is at stake. We see firsthand the farmers struggling to preserve their livelihoods, community leaders forging ahead with audacious resilience strategies, and everyday individuals battling the rising tide. Through intimate interviews with scientists, farmers, and community leaders, "Salted Earth" provides a sobering, yet inspiring look at the very real and present challenge of sea-level rise. It asks a question that affects us all: Can our strategy against the rising sea succeed, or are we fighting an unwinnable war? The answer may unsettle you, but the journey is one you cannot afford to miss. Watch "Salted Earth" and see the future of our world through a salt-streaked lens.
