This course provides a detailed overview of the chemical transformations that control the abundances of key trace species in the Earth’s atmosphere. Emphasizes the effects of human activity on air quality and climate. Topics include photochemistry, kinetics, and thermodynamics important to the chemistry of the atmosphere; stratospheric ozone depletion; oxidation chemistry of the troposphere; photochemical smog; aerosol chemistry; and sources and sinks of greenhouse gases and other climate forcers.

D-Lab: Water, Climate Change, and Health is a project-based, experiential, and transdisciplinary course. Together with peers and experts, we will explore the vitally important interface of water, climate change, and health. This course addresses mitigation and adaptation to climate change as it pertains to water and health. Water-borne illness, malnutrition, and vector-borne diseases represent the top three causes of morbidity and mortality in regions of our focus. Students submit a term project, setting the stage for a lifelong commitment to communicating climate science to a broad public.

This course provides an introduction to the atmospheric chemistry involved in climate change, air pollution and biogeochemical cycles using a combination of hands-on laboratory, field studies, and simple computer models. Lectures will be accompanied by field trips to collect air samples for the analysis of gases, aerosols and clouds by the students.

This course examines representations of race, class, gender, and sexual identity in the media, with a particular focus on new media and how digital technologies are transforming popular culture. We will be considering issues of authorship, spectatorship, (audience) and the ways in which various media content (film, television, print journalism, blogs, video, advertising) enables, facilitates, and challenges these social constructions in society.

This subject examines the paradoxes of contemporary globalization. Through lectures, discussions and student presentations, we will study the cultural, linguistic, social and political impact of globalization across broad international borders.

We will pay attention to the subtle interplay of history, geography, language and cultural norms that gave rise to specific ways of life. The materials for the course include fiction, nonfiction, audio pieces, maps and visual materials.

This course provides an introduction to the causes of international conflict and cooperation. Topics include war initiation, crisis bargaining, international terrorism, nuclear strategy, interstate economic relations, economic growth, international law, human rights, and environmental politics.

Do you know what your bank does with your money? What is the role of a bank in producing societal well-being?

This course looks into banks that operate differently, namely, “just banks" that use capital and finance as a tool to address social and ecological challenges.

This course is for anyone who wants to understand the unique role banks play as intermediaries in our economy and how they can leverage that position to produce positive social, environmental, and economic change.

This reading seminar examines land, water, food, and climate in a changing world, with an emphasis on key scientific questions about the connections between natural resources and food production. Students read and discuss papers on a range of topics, including water and land resources, climate change, demography, agroecology, biotechnology, trade, and food security. The readings are supplemented by short lectures that provide context and summarize main points. The seminar provides a broad perspective on one of the defining global issues of this century. Students consider scientific controversies as well as areas of general agreement and examine practical solutions for addressing critical problems.

This course provides an introduction to the aims and techniques of formal logic. Logic is the science of correct argument, and our study of logic will aim to understand what makes a correct argument good, that is, what is it about the structure of a correct argument that guarantees that, if the premises are all true, the conclusion will be true as well? Our subject (though, to be sure, we can only scratch the surface) will be truth and proof, and the connection between them.

This course is an introduction to the use of accounting information by managers for decision making, performance evaluation and control. The course should be useful for those who intend to work as management consultants, for LFM (Leaders for Manufacturing) students, and in general, for those who will become senior managers.

This course covers the current state of incarceration in the United States and proposals for reform. Class materials include a mix of firsthand/media accounts of incarceration and social science literature on the causes and effects of high incarceration rates. Topics include race and the criminal legal system, collateral consequences of incarceration, public opinion about incarceration, and the behavior of recently elected "reform" prosecutors.

This seminar is a space for collaborative inquiry into the relationships between social movements and the media. We'll review these relationships through the lens of social movement theory, and function as a workshop to develop student projects. Seminar participants will work together to explore frameworks, methods, and tools for understanding networked social movements in the digital media ecology. We will engage with social movement studies as a body of theoretical and empirical work, and learn about key concepts including: resource mobilization; political process; framing; New Social Movements; collective identity; tactical media; protest cycles; movement structure; and more. We'll explore methods of social movement investigation, examine new data sources and tools for movement analysis, and grapple with recent innovations in social movement theory and research. Assignments include short blog posts, a book review, co-facilitation of a seminar discussion, and a final research project focused on social movement media practices in comparative perspective.

This course explores the evolution of poverty and economic security in the United States, within a global context. It examines the impact of recent economic restructuring and globalization, and reviews the current debate about the fate of the middle class, sources of increasing inequality, and approaches to advancing economic opportunity and security. In this class, students will study the topic of poverty and economic security through the lens of the lived experience of Americans: individuals, families, and households; exploring the history, geography, and forces shaping the likelihood of being poor in America.

This course is an introduction to the problems of philosophy—in particular, to problems in ethics, metaphysics, theory of knowledge, and philosophy of logic, language, and science. It takes a systematic rather than historical approach. Readings come from classical and contemporary sources, but emphasis is on examination and evaluation of proposed solutions to the problems.

Here at TILclimate (Today I Learned: Climate), there’s one question we get from our listeners more than any other: “What can I do to make a difference on climate change?” In this special episode of the podcast, three guests who have made acting on climate a big part of their lives join interim host Aaron Krol to share their stories and their advice for those who want to do more. Together, we discuss how to mobilize and inspire others, how small individual actions can lead to large societal ones, and why your contributions to a cooler, more resilient future can have benefits that aren’t just about rising seas or mounting heat waves.

“I love to travel. But I hate the fact that something I love to do, creates so much pollution.” In this episode of TILclimate (Today I Learned: Climate), MIT professor Steven Barrett and host Laur Hesse Fisher dig into how — and why — air travel impacts our earth’s climate, and what solutions are on the horizon. They explore the surprising heating effect of condensation trails (“contrails”), how computer simulations of the earth’s climate system are built, and what scientists and engineers are doing to make flying, well, less bad for the planet.

Humans have changed clouds: where they form, how much precipitation they produce, and how quickly it rains or snows. In this episode of TILclimate (Today I Learned: Climate), MIT professor Dan Cziczo joins host Laur Hesse Fisher to spell out why this is, and what this has to do with climate change. They explore how clouds form in the first place, how human activity has impacted cloud formation and rainfall, and what scientists are still trying to understand. They touch upon the emerging field of geoengineering and how humans could create more clouds to cool the planet -- but we’ll have full episode on that coming out soon.

Humans use around 90 billion metric tons of materials every year, creating about ⅓ of total global greenhouse gas emissions. Which materials produce the most emissions? You might be surprised.

Scientists predict that hurricanes will hit us harder in the future -- but why? And what can we expect to see? In this episode of #TILclimate (Today I Learned: Climate), MIT professor Kerry Emanuel joins host Laur Hesse Fisher to break down how these “heat engines” work and how a changing climate will increase hurricane intensity, storm surges, and flooding. They also explore how people around the world are adapting to growing hurricane risks.

How do we make choices in the face of uncertainty? In this episode of TILclimate (Today I Learned: Climate), MIT professor Kerry Emanuel joins host Laur Hesse Fisher to talk about climate risk. Together, they break down why the climate system is so hard to predict, what exactly scientists mean when they talk about “uncertainty”, and how scientists quantify and assess the risks associated with climate change. Although this uncertainty shrinks every day — as researchers refine their work, computing power grows, and models improve — what we do and how quickly we act will ultimately come down to how much risk we are willing to accept.
