Friday, March 24th, 2023 Michael Garjian on Carbon Dioxide Removal

Michael Garjian will speak about how climate change provides an opportunity to create sustainable community economies by utilizing sustainable power systems and carbon dioxide removal (CDR) technologies such as the CarbonStar system. His 16 years spent in the CDR industry culminated in Michael Garjian’s development, patenting, and successful demonstration of the mobile CarbonStar catalytic vacuum pyrolysis system. The CarbonStar system sequesters atmospheric CO2 by pyrolyzing a variety of biomass feedstocks to produce biochar, bio oils, wood vinegar fertilizer, and biogas to generate electricity to power the CarbonStar system. If widely deployed, the self-sustaining CarbonStar system could sequester megaton levels of CO2 while providing carbon neutral energy and power to urban, rural, and even remote locations wherever a supply of biomass is available. The CarbonStar system has been ranked among the top 80 of 1,300 global CDR technologies entered in Elon Musk’s Carbon XPRIZE.

Michael left the farm to earn a degree in business management from the University of Massachusetts-Amherst Isenberg School Of Management. As a lifelong commercial entrepreneur, social entrepreneur, and author, he holds 11 international patents for alternative lighting systems, electronic power supplies, and atmospheric carbon dioxide removal (CDR) systems. As a commercial entrepreneur he and his wife Irene employed 400 associates producing innovations he developed and sold internationally. As a social entrepreneur in the 2000s, he conceived of and pursued the development of sustainable economic systems while working in community development organizations helping more than one hundred very low income individuals and refugees start small businesses. His work earned a number of awards and was recognized widely by the community, business, and social media of that time. He and his wife Irene are the founders of CarbonStar Systems, Inc., a Massachusetts domestic benefit corporation (B-Corp).

Friday March 10th, 2023 David Hsu on The Origin of Community Choice Aggregation

On Friday, March 10th, David Hsu will speak on The Origin of Community Choice Aggregation and other aspects of the role of concerned citizens in moving local and national policy regarding the energy transition necessary to avoid worsening climate change. A recent paper on the invention of Community Choice Aggregation in Massachusetts sheds light on how to achieve changes in the energy system from the bottom-up, with local organizing and government action. A second recent paper, on the interactions between land use and the built environment with national, economy-wide decarbonization, illustrates how local cities and regions must act to contribute to the energy transition.

David Hsu is an Associate Professor of Urban and Environmental Planning in MIT’s Department of Urban Studies and Planning. Cities connect to their environment through infrastructure, built through physical, technological, and social systems. David's research and teaching focus on how planners, policymakers, and advocates can shape and implement these complex systems using technology, data, and analysis. David taught previously at the University of Pennsylvania and New York University, and worked in structural engineering, real estate finance, and as a policy analyst in the city governments of New York and Seattle. He holds a B.S. from Yale University in physics; a M.S. from Cornell University in applied and engineering physics; a M.Sc. from the London School of Economics and Political Science in city design and social science; and from the University of Washington in Seattle, a Ph.D. in urban design and planning with a certificate in social science and statistics. David is working on a book contracted with the University of Chicago Press on governance of utilities and infrastructure.

Wednesday November 9th, 2022 Kerry Emanuel and Richard Lindzen in A Conversation on Climate Change

At this Conversation on Climate Change, Professors Kerry Emanuel and Richard Lindzen of MIT’s Earth, Atmospheric and Planetary Sciences Department (EAPS) will join us. Kerry and Dick both spoke about climate change issues at Forum meetings last season. Their views differ. These two distinguished experts return to join us in a moderated conversation on climate change. With all the information (and misinformation) regarding climate issues in the popular press and political discourse, this is a rare opportunity for us to ask our questions and to develop a basis for understand the reality.

April 8th, 2022 Friday - Richard Lindzen - Climate Change

In this presentation, Richard Lindzen, Professor (Emeritus) of Meteorology in Earth, Atmospheric and Planetary Sciences (EAPS) at MIT will speak about climate change. Dick is not skeptical about greenhouse warming per se, but he considers the contribution of CO2 to greenhouse warming to be small. Also, there are other contributors to climate that are much more significant. In his view, in promoting any issue, it is important (in a propagandistic sense) to establish ones preferred narrative. In the case of “Dangerous Climate Change”, the narrative is that climate is defined by some global temperature that is, in turn, controlled by carbon dioxide via the greenhouse effect. Unfortunately, most of us accepted the narrative while pointing out the incorrectness of its details such as the assumption of positive feedbacks, the attribution of changes to CO2, and the ignoring of natural internal variability. However, the narrative itself is absurd. Nobody knows what the temperature of the earth refers to. What is actually presented is something referred to as the average temperature anomaly. The variations in this quantity are tiny compared to the scatter of the data points being averaged. At any given time, there are almost as many stations cooling as warming. The earth is characterized by numerous different climate regimes, and it would defy scientific practice to assign the behavior of these numerous climate regimes to this small residue. That said, the earth has been warmer and colder than it is now (viz the ice ages and the Eocene), and there has been no evidence of CO2 causality.

Richard Lindzen received all his degrees from Harvard. His undergraduate major was physics, and his Ph.D. was in applied mathematics, but his thesis dealt with the interaction of radiation, photochemistry and dynamics in the stratosphere. For the remainder of his career he continued to work in the atmospheric sciences. He has held professorships at the University of Chicago, Harvard University, and the Massachusetts Institute of Technology. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the Norwegian Academy of Science and Letters. He is a fellow of the American Meteorological Society, the American Geophysical Union, and the American Association for the Advancement of Science.

Friday February 25th, 2022. Yang Shao-Horn on Addressing Scientific Challenges Towards Mitigating Climate Change

Addressing Scientific Challenges Towards Mitigating Climate Change 

There is an urgent need to reduce our global carbon dioxide emissions to mitigate climate change. While low-cost electricity from solar and wind provides exciting opportunities to reduce emissions, converting electricity to efficient carbon-free or carbon-neutral energy carriers at scale such as stored electrons, fuels and heat remains challenging to deep decarbonization. Electrochemical reactions are central to electrification via batteries, electrolysis in making decarbonized chemicals, fuels and materials, and negative emission technologies, which represent three important capabilities to connect electricity with our energy demands. Fundamental research on surface and molecular sciences, electron/ion transfer, and ion transport is instrumental to address scientific challenges and make breakthroughs in the core technologies such as lithium batteries and production of hydrogen-based carriers and metals. In this lecture, we will address scientific challenges and recent progress in regulating surface oxygen activity and tuning interfacial hydrogen bonds to enhance the functions of lithium batteries, and electrocatalysis of water splitting.

Yang Shao-Horn is JR EAST Professor of Engineering and faculty in the Department of Mechanical Engineering, Department of Materials Science and Engineering and the Research Laboratory of Electronics at MIT.
