Perhaps you have heard the adage “think globally, act locally.” An MIT-led project taking that idea to heart has demonstrated a new method for getting local citizens and leaders to agree on the best ways of managing the immediate and long-term effects of climate change.  

The New England Climate Adaptation Project (NECAP) got local citizens and officials in four coastal towns to engage in role-playing games about climate change tailored to their communities, while conducting local polling about attitudes and knowledge about climate risks. In so doing, the project helped the towns reach new conclusions about local initiatives to address the threats posed by climate change— which in coastal communities may include rising sea levels and increased storm surges that can lead to flooding.

“One hour of conversation can completely alter people’s sense [and show] that this is a problem they can work on locally,” says Lawrence Susskind, the Ford Professor in Urban Studies in MIT’s Department of Urban Studies and Planning (DUSP), who led the project and has now co-authored a new book detailing its results. “There are a bunch of things local governments can do, and people can do for themselves — that communities can do.”

The findings stem from years of research and organizing in four places: Wells, Maine; Dover, New Hampshire; Barnstable, Massachusetts; and Cranston, Rhode Island. The new book on the effort, “Managing Climate Risks in Coastal Communities,” has just been released by the academic publisher Anthem Press.

Among the many findings of the project is that residents of these coastal communities were typically far more concerned about the consequences of climate change than local politicians realized.

“People in official positions really underestimated the extent to which [citizens] were worried about what climate change might mean to the town, what their vulnerabilities were,” Susskind explains. “If you asked, ‘What percentage of people do you think believe climate change is a problem right now?’ most officials would have said less than 10 percent. Our polling results were about 60 percent.”

The scenarios that the MIT-led team presented to people in each place involved ranges of probability regarding potential events. And yet, Susskind emphasizes, certain types of climate responses, like building better storm drains, may be necessary in almost any scenario.

“Lots of uncertainty doesn’t mean you can’t decide or know what to do,” Susskind says. “There are no-regrets actions you can take, where you won’t regret spending the money, time, or effort later.”

Four towns, many issues

The scholars chose the four towns because each hosts a center for the National Estuarine Research Reserve System, a branch of the National Oceanic and Atmospheric Administration. That made it simpler for the project leaders to make connections with local political leaders and convince them to participate in the climate adaptation project.  

The book is co-authored by four project leaders, including Susskind, who heads the Environmental Policy and Planning Group at DUSP as well as the mediation group he founded, the Consensus Building Institute (CBI); Danya Rumore, visiting assistant professor at the University of Utah; Carrie Hulet, a senior associate at the CBI; and Patrick Field, co-managing director of the CBI and an associate director of the MIT-Harvard Public Disputes Program.

After developing climate-change scenarios for each town and conducting research on local political priorities and infrastructure, starting in 2012, the MIT group developed a role-playing game tailored to each town, and conducted debriefings on the issues as well. Citizens who participate study the local climate scenarios and potential responses, and try to reach consensus on plans of action. An investment of a few hours can suddenly make hundreds of community members more informed and willing to consider the need for climate response.

“The science doesn’t dictate things, but it informs things, and it leads to interesting conversations about what the policy for their own community should be,” Susskind says.

In Dover, for instance, the effort helped clarify the need to act on local concerns about flooding from the town’s river, and about the capabilities of the town’s storm drains; dredging the river and updating the drains are now higher priorities, along with having more generators on hand for emergency response activities. In Barnstable, where sea level rise, flooding, drought, and storm damage are all problematic issues, the project clarified the need to add water supplies and make the electrical grid more sustainable.

In Wells, where sea levels are projected to rise by 2 to 5 feet by 2099, the project highlighted the need for seawalls and a buyback program for privately owned coastal land that could absorb flooding. In Cranston, flooding is a major issue — following floods the town experienced in 2010 — and the project revealed that 86 percent of residents are concerned about climate change. Possible measures include engineered barriers and expanded wetlands, but the project also reveals a need for continued public education programs about the affordability of possible responses.

Still, acting sooner rather than later, Susskind suggests, will usually turn out to be a wise investment.

“Don’t be convinced that was a one-time flood,” he says. “It’s going to happen sooner and more often than you think, and the cost could be enormous without some effort to manage risks. And maybe as a community you say, ‘Bad things are going to happen unless we find some way to reduce our vulnerabilities.’”

Adaptation, as well as mitigation

The MIT-led project dealt with climate adaptation, the response to climate change risks. As Susskind acknowledges, that is only one part of the climate-action picture; the issue of climate mitigation — that is, preventing climate change from happening to the fullest extent possible — is also vital.

And while the role-playing games were limited to smaller communities, Susskind acknowledges, he thinks this approach can work in much larger municipalities as well, based on similar work he has done in Maryland and other places.

“I don’t think there are any problems of scaling up,” he says.

Other scholars have found the project and its results to be valuable. Judith Innes, a professor emerita of city and regional planning at the University of California at Berkeley, calls it an “eye-opening book” that offers “hope and guidance to policy makers and citizens who want to act before it is too late.”

The researchers have put many materials online, available for public study. However, Susskind says, there is no substitute for participating in the project’s games in person, to work through issues of evaluating a town’s needs and negotiating over them.

“The whole point politically is to organize a constituency for change in each locality, and that requires face-to-face interaction,” Susskind says. “There’s no substitute. I design different games for different places. You have to tailor it so that people get a sense they’re learning something about the place where they are. It’s about empowering a community to feel we can and should be working to anticipate and manage climate risks.”

Volkswagen’s use of software to evade emissions standards in more than 482,000 diesel vehicles sold in the U.S. will directly contribute to 60 premature deaths across the country, a new MIT-led study finds.

In September, the Environmental Protection Agency discovered that the German automaker had developed and installed “defeat devices” (actually software) in light-duty diesel vehicles sold between 2008 and 2015. This software was designed to sense when a car was undergoing an emissions test, and only then engage the vehicle’s full emissions-control system, which would otherwise be disabled under normal driving conditions — a cheat that allows the vehicles to emit 40 times more emissions than permitted by the Clean Air Act.

That amount of excess pollution, multiplied by the number of affected vehicles sold in the U.S. and extrapolated over population distributions and health risk factors across the country, will have significant effects on public health, the study finds.

Assessing health outcomes

According to the study, conducted by researchers at MIT and Harvard University and published in the journal Environmental Research Letters, excess emissions from Volkswagen’s defeat devices will cause around 60 people in the U.S. to die 10 to 20 years prematurely. If the automaker recalls every affected vehicle by the end of 2016, more than 130 additional early deaths may be avoided. If, however, Volkswagen does not order a recall in the U.S., the excess emissions, compounding in the future, will cause 140 people to die early.

In addition to the increase in premature deaths, the researchers estimate that Volkswagen’s excess emissions will contribute directly to 31 cases of chronic bronchitis and 34 hospital admissions involving respiratory and cardiac conditions. They calculate that individuals will experience about 120,000 minor restricted activity days, including work absences, and about 210,000 lower-respiratory symptom days.

In total, Volkswagen’s excess emissions will generate $450 million in health expenses and other social costs, the study projects. But a total vehicle recall by the end of 2016 may save up to $840 million in further health and social costs.

Steven Barrett, the lead author of the paper and an associate professor of aeronautics and astronautics at MIT, says the new data may help regulatory officials better estimate the effects of Volkswagen’s actions.

“It seemed to be an important issue in which we could bring to bear impartial information to help quantify the human implications of the Volkswagen emissions issue,” Barrett says. “The main motivation is to inform the public and inform the developing regulatory situation.”

Cheating (and) death

To estimate the health effects of Volkswagen’s excess emissions, Barrett and his colleagues at MIT and Harvard based their calculations on measurements by researchers at West Virginia University, who found that the vehicles produced up to 40 times the emissions allowed by law. They then calculated the average amount that each vehicle would be driven over its lifetime, and combined these results with sales data between 2008 and 2015 to estimate of the total excess emissions during this period.

The group then calculated the resulting emissions under three scenarios: the current scenario, in which 482,000 vehicles have already emitted excess emissions into the atmosphere; a scenario in which Volkswagen recalls every affected vehicle by the end of 2016; and a future in which there is no recall, and every affected vehicle remains on the road, continuing to emit excess pollution over the course of its lifetime.

The group then estimated the health effects under each emissions scenario, using a method they developed to map emissions estimates to public exposure to fine particulate matter and ozone. Diesel vehicles emit nitrogen oxides, which react in the atmosphere to form fine particulate matter and ozone. Barrett’s approach essentially maps emissions estimates to population health risk, accounting for atmospheric transport and chemistry of the pollutants.

“We all have risk factors in our lives, and [excess emissions] is another small risk factor,” Barrett explains. “If you take into account the additional risk due to the excess Volkswagen emissions, then roughly 60 people have died or will die early, and on average, a decade or more early.”

Barrett says that, per kilometer driven, this number is about 20 percent of the number of deaths caused by road transport accidents.

“So it’s about the same order of magnitude, just from these excess emissions,” Barrett says. “If nothing’s done, these excess emissions will cause around another 140 deaths. However, two-thirds of the total deaths could be avoided if the recalls could be done quickly, in the course of the next year.”

Daniel Kammen, the editor-in-chief of Environmental Research Letters and a professor of energy at the University of California at Berkeley, says the group’s study provides a “rigorous evaluation of the scale of the impacts, which are potentially exceedingly serious.

“The analysis demonstrates the value of policy-inspired fundamental research where the air quality and health impacts of transgressions such as the VW issue can be calculated, and made available for public discussion,” says Kammen, who did not contribute to the research.

Within this century, parts of the Persian Gulf region could be hit with unprecedented events of deadly heat as a result of climate change, according to a study of high-resolution climate models.

The research reveals details of a business-as-usual scenario for greenhouse gas emissions, but also shows that curbing emissions could forestall these deadly temperature extremes.

The study, published today in the journal Nature Climate Change, was carried out by Elfatih Eltahir, a professor of civil and environmental engineering at MIT, and Jeremy Pal PhD ’01 at Loyola Marymount University. They conclude that conditions in the Persian Gulf region, including its shallow water and intense sun, make it “a specific regional hotspot where climate change, in absence of significant mitigation, is likely to severely impact human habitability in the future.”

Running high-resolution versions of standard climate models, Eltahir and Pal found that many major cities in the region could exceed a tipping point for human survival, even in shaded and well-ventilated spaces. Eltahir says this threshold “has, as far as we know … never been reported for any location on Earth.”

That tipping point involves a measurement called the “wet-bulb temperature” that combines temperature and humidity, reflecting conditions the human body could maintain without artificial cooling. That threshold for survival for more than six unprotected hours is 35 degrees Celsius, or about 95 degrees Fahrenheit, according to recently published research. (The equivalent number in the National Weather Service’s more commonly used “heat index” would be about 165 F.)

This limit was almost reached this summer, at the end of an extreme, weeklong heat wave in the region: On July 31, the wet-bulb temperature in Bandahr Mashrahr, Iran, hit 34.6 C — just a fraction below the threshold, for an hour or less.

But the severe danger to human health and life occurs when such temperatures are sustained for several hours, Eltahir says — which the models show would occur several times in a 30-year period toward the end of the century under the business-as-usual scenario used as a benchmark by the Intergovernmental Panel on Climate Change.

The Persian Gulf region is especially vulnerable, the researchers say, because of a combination of low elevations, clear sky, water body that increases heat absorption, and the shallowness of the Persian Gulf itself, which produces high water temperatures that lead to strong evaporation and very high humidity.

The models show that by the latter part of this century, major cities such as Doha, Qatar, Abu Dhabi, and Dubai in the United Arab Emirates, and Bandar Abbas, Iran, could exceed the 35 C threshold several times over a 30-year period. What’s more, Eltahir says, hot summer conditions that now occur once every 20 days or so “will characterize the usual summer day in the future.”

While the other side of the Arabian Peninsula, adjacent to the Red Sea, would see less extreme heat, the projections show that dangerous extremes are also likely there, reaching wet-bulb temperatures of 32 to 34 C. This could be a particular concern, the authors note, because the annual Hajj, or annual Islamic pilgrimage to Mecca — when as many as 2 million pilgrims take part in rituals that include standing outdoors for a full day of prayer — sometimes occurs during these hot months.

While many in the Persian Gulf’s wealthier states might be able to adapt to new climate extremes, poorer areas, such as Yemen, might be less able to cope with such extremes, the authors say.

Christoph Schaer, a professor of atmospheric and climate science at ETH Zurich who was not involved in this study, provided an independent commentary in the journal, writing that while deadly heat waves have occurred recently in Chicago, Russia, and Europe, in these cases infants and the elderly were most affected. The new study, Schaer writes, “concerns another category of heat waves — one that may be fatal to everybody affected, even to young and fit individuals under shaded and well-ventilated outdoor conditions.”

Schaer writes that “the new study shows that the threats to human health may be much more severe than previously thought, and may materialize already in the current century.” He told MIT News, “I think the study is of great importance, since it indicates where heat waves could get worst if climate change proceeds.”

The research was supported by the Kuwait Foundation for the Advancement of Science.

MIT is launching a multifaceted five-year plan aimed at fighting climate change, representing a new phase in the Institute’s commitment to an issue that, the plan says, “demands society’s urgent attention.”

Citing “overwhelming” scientific evidence, “A Plan for Action on Climate Change” underscores the “risk of catastrophic outcomes” due to climate change and emphasizes that “the world needs an aggressive but pragmatic transition plan to achieve a zero-carbon global energy system.”

To that end, MIT has developed a five-year plan to enhance its efforts in five areas of climate action, whose elements have consensus support within the MIT community:

• research to further understand climate change and advance solutions to mitigate and adapt to it;
• the acceleration of low-carbon energy technology via eight new research centers;
• the development of enhanced educational programs on climate change;
• new tools to share climate information globally; and
• measures to reduce carbon use on the MIT campus.

The plan calls for MIT to convene academia, industry, and government in pursuit of three overlapping stages of progress.

“The first step,” according to the plan, “is to imagine the future as informed by research: e.g., What is the optimal mix of energy sources in 15, 25 and 35 years, in order to meet emissions targets and eventually reach a zero-carbon global energy system? And how can societies across the globe best adapt to damaging climate impacts in the meantime?”

“Next,” the plan continues, “it will be vital to establish the policy and economic incentives to achieve that future. Finally, clear technological goals and aligned incentives will focus and accelerate the research and development required to achieve success. All three phases need to be continuously refreshed: Research and development should continuously inform timelines and targets. The success of this strategy depends on the best efforts of all three sectors.”

The plan specifically asserts the need for a price on carbon in order to align the incentives of industry with the imperatives of climate science.

The plan also announces that MIT will not divest from the fossil fuel industry. This decision and the overall plan emerged from more than a year of broad consultation with the MIT community, including extensive public discussion led by the Committee on the MIT Climate Change Conversation, and engagement with the student-led group Fossil Free MIT. This group originally petitioned MIT to divest from 200 companies and more recently has asked for “reinvestment in campus sustainability, and a reinvention of the approach that MIT takes toward climate change.”

In his announcement letter today to the MIT community, President L. Rafael Reif said the plan would not have taken the shape it did without Fossil Free MIT’s “willingness to work with us toward the shared goal of meaningful climate action.” He encouraged the group’s members to join in the work ahead.

A call to service, on campus and beyond

In his letter, Reif called upon all members of the MIT community to take action. “There is room and reason for each of us to be part of the solution,” he wrote. “I urge everyone to join us in rising to this historic challenge.”

Alumni are being called upon to imagine how they can help MIT execute the plan. A competition announced in the plan has been created in order to elicit the most effective ways for the MIT alumni community to take personal and combined action.

“MIT’s 130,000 alumni represent an exceptional untapped resource for driving substantive progress on climate change,” the plan says, “and we are certain that our graduates will know better than we do how to make the most of their strength, from their technical expertise to their professional and community networks.”

The competition will be hosted by the MIT Climate CoLab, a digital community that engages nearly 50,000 people from over 170 countries to crowdsource climate priorities and novel solutions. The plan calls for the Climate CoLab to expand its overall capacity, so that MIT can serve as a vital hub of crowdsourced solutions to climate change.

A year and more in the making

The plan is the result of an MIT-wide initiative on climate launched in May 2014, and led by Provost Martin Schmidt; Vice President for Research Maria Zuber; MIT Energy Initiative (MITEI) Director Robert Armstrong; and Susan Solomon, founding director of MIT’s Environmental Solutions Initiative.

In September 2014, the initiative appointed the Committee on the MIT Climate Change Conversation, chaired by Roman Stocker, then associate professor of civil and environmental engineering, to lead public discussion of MIT’s options for addressing climate change.

The plan credits members of the committee, as well as members of Fossil Free MIT, for having “brought climate change to the top of MIT’s institutional agenda by urging that MIT assume a role of public leadership.”

“Today’s plan is truly MIT’s plan,” Zuber says. “There is a hunger across the Institute to apply MIT’s strengths to the problem. With a firm theory of the case for how to bring cohesion to our work in science, engineering, and policy, we are now poised to set forth on five years of critical work. Today is an important beginning.”

In his letter to the MIT community, Reif wrote that MIT will rely on Zuber to lead MIT’s research, outreach, and convening efforts.

“President Reif and Vice President for Research Zuber have led us to a very important day in the Institute’s history,” says Diana Chapman Walsh, a member of the Executive Committee of the MIT Corporation (MIT’s board of trustees) and former president of Wellesley College. “The world is calling for leadership at a time of urgency and uncertainty. Today, MIT is deepening its commitment to meaningful action.”

Intensifying MIT’s impact

The plan outlines five areas for “direct action”:

1. An improved understanding of climate change, and practical solutions to mitigate and adapt to it. As part of its Environmental Solutions Initiative (ESI), now led by Professor John E. Fernandez, who was named as ESI’s second director earlier this week, MIT is providing $5 million to back further research on a series of cross-disciplinary projects and will seek outside support for promising new work.

2. Accelerating progress on low-carbon technologies. Building on decades of faculty research, the MIT Energy Initiative is planning to launch eight new low-carbon energy centers, in cooperation with corporate partners, each focused on the advancement of a specific type of technology. Each center will seek about $8 million in annual funding, or more than $300 million in total over the five-year period — which the plan says represents “far and away the greatest opportunity for MIT to make a difference on climate change.” The eight centers will be in the areas of solar energy; energy storage; materials; carbon capture, use, and sequestration; nuclear energy; nuclear fusion; energy bioscience; and the electrical grid.

1. In addition, MIT plans additional research intended to help transform at least four major types of energy-related systems. These projects will concern the future of the utility industry, ground transportation, air transportation, and cities. And MIT is commissioning a multidisciplinary report to envision the pathway to accelerate the transition to a zero-carbon future.

3. Education. MIT plans to create an Environment and Sustainability degree option; develop an online Climate Change and Sustainability credential; and, in a joint effort between MIT’s School of Engineering and School of Architecture and Planning, find ways to insert principles of “benign and sustainable design” throughout MIT’s engineering and design instruction.

4. Additional knowledge-sharing tools. MIT will expand its range of short courses and seminars for executives (including through online tools); create a new web portal on climate change; expand its Climate CoLab crowdsourcing tool (as noted above); and continue to focus on climate issues through Solve.

5. Reducing emissions on the MIT campus, and using the campus as a “test bed” for climate action. MIT plans to reduce campus emission by at least 32 percent by 2030 (the amount set as a goal by the federal government); eliminate the use of fuel oil on campus by 2019; enact “carbon shadow pricing,” to explore the effects of assigning a self-imposed cost to campus carbon emissions; pursue more carbon-efficient technologies as it renews its stock of campus buildings and systems; and build an open data platform on campus energy use.

Former Secretary of State George P. Shultz, who earned a PhD from MIT in 1949 and served on the economics faculty in the 1950s, has urged the MIT community to take action on climate change and endorses today’s plan, calling it “a terrific document. It is inspirational that MIT is working on the subject with such energy and impact.” Shultz chairs the External Advisory Board of the MIT Energy Initiative.

Robert Armstrong, director of the MIT Energy Initiative, says, “The plan recognizes the central role that climate change will have in driving transformation of the global energy system. The eight low-carbon energy centers leverage MIT’s strengths in working across disciplines and in deeply engaging with industry to tackle society’s greatest challenges.”

Investment questions

The plan announces that in the interest of fighting climate change, MIT will not divest from companies in the fossil fuel sector.

“We believe that divestment — a dramatic public disengagement — is incompatible with the strategy of engagement with industry to solve problems that is at the heart of today’s plan. Combatting climate change will require intense collaboration across the research community, industry and government,” the plan states.

Divestment has been a principal aim of Fossil Free MIT, which had gathered 3,400 signatures from members of the MIT community, asking for divestment from 200 companies in the fossil-fuel industry. MIT hosted a public debate on the issue in April, in which MIT faculty, professors from other institutions, and investment executives addressed the potential merits and drawbacks of divestment.

The plan states that MIT is “not naïve about the pernicious role of some segments of the fossil fuel industry in creating the current policy deadlock. We deplore the practice of ‘disinformation,’ through which some industry players and related groups have actively obstructed clear public understanding of the problem of climate change.”

MIT’s position, the plan states, is that “well-crafted policies can harness the creative forces of industry to serve the common good.” Further, it argues “that growing awareness of climate change may be generating a tipping point in that policy dynamic now. Witness the fact that in Paris last Friday, October 16, the CEOs of ten of the world’s largest oil and gas companies declared that their ‘shared ambition is for a 2°C future,’ and called for ‘an effective climate change agreement’ at next month’s 21st session of the United Nations Conference of Parties to the UN Framework on Climate Change (COP21).”

“Six of those companies — BP, Eni, Saudi Aramco, Shell, Statoil, and Total — are members of MITEI,” the plan continues. “We believe we have greater power to build on such momentum not by distancing ourselves from fossil fuel companies, but by bringing them closer to us.”

Ultimately, the plan states, massive changes are needed in the production, distribution, and consumption of energy to avert a potential climate catastrophe: “To solve this global problem, humanity must reorder the global energy status quo.”

Robert Millard, chairman of the MIT Corporation, calls the plan “bold, respectful, complete, honest, and well-reasoned. It therefore reflects,” he says, “the highest aspirations of MIT."

John E. Fernandez, a professor of building technology in the Department of Architecture, has been named as the new director of MIT’s Environmental Solutions Initiative (ESI), a campuswide initiative launched in 2014. Fernandez succeeds Susan Solomon, the Ellen Swallow Richards Professor in the Department of Earth, Atmospheric and Planetary Sciences, who has served as the Initiative’s founding director.

“I’m honored to be taking over from such an eminent scientist,” says Fernandez, who has served on the MIT faculty for 16 years. “It’s really humbling to hear her talk about her work and be given the opportunity to extend the reach of the ESI.”

Fernandez’s appointment was announced today in a letter to the MIT community from Provost Martin Schmidt and Vice President for Research Maria Zuber.

“Professor Fernandez approaches this role as a world expert on high-performance, sustainable building materials, as a leading scholar on the resources and infrastructure of cities — home to more than half the human population — and as a practicing architect who has led the design for more than 2.5 million square feet of new construction in cities from Washington, D.C., New York, and Los Angeles to Jakarta, Tokyo, and Shanghai,” Schmidt and Zuber wrote. “A member of our faculty since 1999, he founded and directs the Urban Metabolism Group, a highly multidisciplinary research group that studies how intelligent design and technology can reduce the resource intensity of cities.”

Since its founding in May of last year, ESI has awarded nine seed grants for research projects, on efforts that include promoting sustainable consumption in cities, improving methods for safe mining on land and at sea, and improving air quality and plans to mitigate global climate change. Such highly multidisciplinary projects can be difficult to fund through traditional channels.

“I’m delighted to be passing the reins to such a well-qualified and distinguished scholar,” Solomon says. “John Fernandez has a deep understanding of MIT’s strengths across a very diverse suite of environmental challenges, and he brings a clear commitment to excellence and breadth. I’ll be looking forward to seeing him take ESI to the next level.”

Fernandez says ESI’s broad scope is illustrated by the very different backgrounds of its first two directors. “I’m very optimistic about the vision for ESI,” he says: If this initiative can embrace leaders from fields as different as atmospheric science, architecture, and building technology, “It speaks to the breadth of MIT, and the commitment to the ESI.”

Fernandez’s research looks at the environmental consequences of societal activities — which tend to be concentrated in the world’s cities. “Decisions that architects and planners make can have huge ramifications, because the built environment accounts for the consumption of enormous quantities of energy and materials,” he says. Such environmental consequences, he says, “should be integral to a designer’s thinking process.”

“The Intergovernmental Panel on Climate Change has shown the built environment to be one of the major contributors to global emissions,” Fernandez says. “What is less well known is that a majority of raw materials extracted and processed are used in the construction and operation of buildings, roads and other large-scale infrastructure. For that reason, much of my work has been focused on understanding the environmental benefits of resource-efficient buildings and cities.”

Since more than half of the world’s population now lives in urban areas, Fernandez says, he has focused on systems involved in the functioning of modern cities, from buildings and transportation to the delivery of food, water, sanitation services, and goods — and the resource intensities associated with these services. The research outcomes from his group contribute to a field known as “urban metabolism,” because it treats the city as an interconnected whole, rather than focusing on individual components or economic sectors. This is best done through a multidisciplinary approach.

In the work of the ESI, Fernandez says, “many solutions will require multiple perspectives” — which underscores the importance of communication and collaboration among disciplines, and an understanding of different modes for tackling problems through science, engineering, design, and policy.

Fernandez sums up his vision for the Initiative by considering the three components of its name: environmental, solutions, and initiative.

On the environment, he says, “the priority is to progress beyond the discussion of the uncertainties about climate change, to delve deeper into research that tells us more about the consequences of climate change, and to do research in targeted ways that will tell us about the kinds of risks we are facing.” Researchers tackling those issues should be provided with resources to do their work, but also to help them in communicating “a very simple but unequivocal message that the science of the climate is well-established and the most conclusive it can be, and is telling us very dire things that we should really pay attention to.”

The second priority, Fernandez says, lies in solutions. It’s essential, he says, “to propose pathways toward mitigation and adaptation in every aspect of society, with regard to every important human activity, enlisting engineers, scientists, architects, economists, political scientists, and others, and with regard to all regions of the world.” For example, hundreds of millions of people live in coastal cities, which face significant threats from sea-level rise. Designers need to converge on integrated solutions with other disciplines to enlist multiple systems for adapting these cities, he says “so that we’re not approaching this in a siloed way.”

The initiative part of the ESI’s name, Fernandez says, “is the part that I hope will bear important short-term and local results for MIT. I believe this initiative has the critical responsibility to initiate action across diverse communities at MIT.”

The ESI, Fernandez adds, should involve all sectors of our community — undergraduate and graduate students, postdocs, faculty, researchers, and staff. “We will be working to initiate a great many actions for the environment, both local and global,” Fernandez says. “Some will be very targeted and modest, and others extraordinarily ambitious, broad and sweeping.”

One example of a way in which Fernandez hopes to implement this agenda, he says, is in funding student projects, including some that might relate directly to residential life: “Support for even very modest but very immediate grassroots projects, where it’s right there in front of you, is something I’m very keen to launch as soon as possible,” he says.

Over two weeks in December, delegates from virtually every country in the world will gather in Paris for the 21st annual United Nations Climate Change Conference. Their ambitious goal: to hammer out a binding international agreement on climate action.

In advance of the conference, organizers have requested that countries submit Intended Nationally Determined Contributions — pledges to reduce greenhouse gas emissions, by an amount that should be “fair and ambitious,” in order to limit global warming to no more than 2 degrees Celsius above pre-industrial levels.

Now a new study by researchers at MIT and the Center for International Climate and Environmental Research in Oslo, Norway, has found that pledges by the three largest emitters — the United States, the European Union, and China — leave very little room for the rest of the world to emit.

Based on the pledges submitted, the U.S. plans to reduce emissions by 28 percent by 2025, and 83 percent by 2050, while the EU will work toward reductions of 40 percent by 2030, and 80 percent by 2050. China has not pledged a reduction, but has indicated that its emissions will peak by 2030; China also aims to improve its energy efficiency by 60 to 65 percent.

Despite these substantial commitments, the researchers found that the rest of the world’s nations would be forced to adopt per capita emissions 7 to 14 times lower than the EU, U.S., or China, by 2030, in order to keep global temperatures from rising higher than 2 C.

“The challenge of this problem is, we have about 7 billion people on the planet, and about 1 billion of us live pretty well,” says Susan Solomon, the Ellen Swallow Richards Professor of Atmospheric Chemistry and Climate Science at MIT. “The other 6 billion are struggling to develop, and if they develop using carbon as we did, the planet is going to get quite hot. And hot is, of course, just the beginning of the story in terms of what climate change actually means.”

Solomon and her colleagues have published their results in the journal Environmental Research Letters.

What’s fair?

While countries were asked to demonstrate that their pledges were fair and ambitious, conference organizers provided no framework with which to make such an assessment.

In the new study, the MIT and Norwegian scientists gauged the fairness and ambition of the top three emitters’ pledges using a “cumulative emissions” approach developed by the Fifth Assessment Report of the Intergovernmental Panel on Climate Change.

The cumulative emissions approach finds that a best estimate of 3.7 trillion tons of carbon dioxide can be emitted globally before temperatures rise 2 C above pre-industrial levels. Given the amount of carbon dioxide emitted thus far, and accounting for other greenhouse gases, land-use change, and other factors, the remaining amount is about 1 trillion tons — about 30 years’ worth of current emissions.

How to fairly allocate the remaining allowable emissions among the world’s nations is a complex and contentious issue. Solomon and her colleagues examined two scenarios for fairly reducing emissions by the EU, U.S., and China: an equity approach, which divides the global quota of emissions among all nations based on population; and an inertia approach, which divides the quota based on the current shares of global emissions.

Based on their calculations, they found all three emitters’ pledges fall short of fair: The U.S. and EU pledges may be considered in line with keeping global warming at 2 C only under the inertia scenario, in which the high emitters continue to emit based on their current shares. If, however, both were to adopt an equity scenario, they would have to pledge significantly more emissions reductions, to account for their relatively small share of the world’s population.

China’s pledge deviates significantly from both scenarios, as both would require the country to immediately begin drastic reductions. Instead, China has pledged to begin reducing its emissions in 2030, so as to improve the quality of living for its millions of citizens now living under the poverty line.

“The environment we ask for”

In sum, Solomon and her colleagues conclude that even if the three largest emitters fulfill their pledges, they would “lock the world into a higher long-term temperature increase” of around 3 C.

“People don’t realize that 2 degrees Celsius is a big change,” Solomon says. For instance, she points to the summer of 2003, in which an unprecedented hot summer killed more than 10,000 people throughout Europe.

“That summer was about 2 degrees Celsius hotter than an average European summer,” Solomon says. “By 2050, every summer in Europe will probably be 2 degrees hotter than average, if we keep going the way we’re going right now. Three degrees, in my opinion, is a really frightening change.”

To stave off additional warming, Solomon says countries will need to significantly ramp up efforts to decarbonize. In the short term, she says, international climate talks must integrate discussions on research and development, to spur technological innovation.

“We have to decarbonize the energy system via research and development, changes in technologies and policies, and we need to encourage those to happen,” Solomon says.  “We’ll get the environment we ask for. History has proven time and again that public engagement is essential in making anything change on this planet.”

Solar panel system wins $10,000 prize for technology that makes energy and water more accessible in the developing world

An MIT initiative is using the global crowd to help solve climate change. And with the United Nations’ climate agreement anticipated to fall short of the 2 degree Celsius carbon emissions target, it’s never been a more critical time to take this approach.

MIT’s Climate CoLab initiative is a growing community of 50,000 people from around the world who work together online through a series of interrelated contests focused on different aspects of the climate change problem. Yesterday, MIT hosted the Crowds and Climate conference, where the Climate CoLab awarded its 2015 contest winners.

Eden Full from the non-profit SunSaluter won the $10,000 Grand Prize for its technology that makes energy and water more accessible in the developing world. Their product uses gravity and water to rotate a solar panel throughout the day, generating 30 percent more electricity than a standard panel and four liters of clean drinking water each 24-hour period. The rotator is cheaper than motorized solar trackers and has already achieved success: there are already 130 SunSaluters in 16 countries.

"This prize is especially important now," said Full, founder of the project. "We just decided that SunSaluter will become fully volunteer-led, supported by our non-profit and corporate partners. This funding will go toward making that possible."

In addition, two proposals received honorable mention awards:

• A national campaign on energy conservation and renewable energy in Indian schools that is working towards building a network of energy ambassadors. The campaign already has support from the Indian government, and is well on its way to fostering a more environmentally-aware generation of Indians.
• A mechanism for internalizing marine emissions that combines charging a levy on emissions from international maritime shipping, with a fuel levy on fuel consumption by domestic shipping

These proposals were selected by Robert Armstrong, director of the MIT Energy Initiative; Jason Jay, director of the MIT Sloan Sustainability Initiative; John Reilly, co-director of the Joint Program on the Science and Policy of Global Change.

The grand prize and honorable mention awards were selected from the 34 winners of the 24 contests run on the Climate CoLab in 2015. The winners are a diverse group of non-profits, entrepreneurs, scholars and climate experts, students, business people, and concerned citizens looking to confront the climate challenge, who hail from 11 countries.

The Climate CoLab also announced the winner of its United States Climate Action Plan contest, which sought regional solutions to climate change. Unlike the other contests, which target specific sub-problems that contribute to climate change, this contest asked participants to take different actions and combine them to form a regional strategy.

The winner for the United States Climate Action Plan contest suggested a pathway to engineer cities so that they are built for livability, sustainability, resiliency, energy-efficiency and affordability.

An important addition to this round of contests is a tool — and a team of climate modelers — to help people to evaluate the impact their ideas will have on global emissions. The public can also combine regional plans to form global strategies. The Global Climate Action Plan contest is still open and accepting submissions until Oct. 17th.

All the winners were recognized at the Crowds and Climate conference, held this week alongside MIT’s Solve conference. Crowds and Climate brought together leaders from businesses, non-profit organizations, governments, and communities around the world to advance an online global problem-solving effort to more effectively tackle climate change. This bottom-up approach enables large communities of people to work together to shift business practices, influence policy makers, and reshape public attitudes and behavior on climate change.

“Our goal is to open up the elite conference rooms and meeting halls where climate strategies are developed today and bring that discussion into an online forum where anyone with a good idea can contribute,” says Professor Thomas Malone, director of the Center for Collective Intelligence at the MIT Sloan School of Management and principal investigator for the Climate CoLab project.

“We are very proud of this year’s winners, and we see this as just the beginning of new ways to use our global collective intelligence to tackle important societal problems like climate change.”

The Joint Program is a cosponsor of the Crowds & Climate conference.
