In October 2018, the Intergovernmental Panel on Climate Change announced that limiting global warming to 1.5°C would require rapid, far-reaching and unprecedented change in all aspects of society. The length of the 1.5 Minute Climate Lectures represents 1.5°C — the maximum amount the average temperature can rise in order to avoid the worst consequences of global warming.

For this year’s 1.5* Minute Climate Lectures during Climate Week at Penn 2025, six University of Pennsylvania experts will share their perspectives on Climate Solutions.

Guy Grossman, MIgration is a sensible form of climate adaptation.

Leigh Stearns, Navigating the Arctic: Why we urgently need coordinated satellite data and AI

Michael Weisberg, Islands as Hot Spots

Dorit Aviv, Harnessing the Sun to Keep us Cool

Steve Decina, In Defense of Hot Air

Jennifer Wilcox, Hot Spots in Carbon Capture: Building the Full Solution

Robert Habeck, Reframing the Energy Trilemma

*1.5 degrees Celsius = The maximum amount the average temperature can rise in order to avoid the worst consequences of global warming. We're already past 1 degree Celsius.

Speakers

Guy Grossman

Guy Grossman

David M. Knott Professor of Global Politics and International Relations Penn Arts & Sciences, Political Science Dept.

Guy Grossman, PhD, the David M. Knott Professor of Global Politics and International Relations at the political science department at the University of Pennsylvania. His research is in applied political economy, with a substantive focus on governance, migration and forced displacement, human trafficking, and conflict processes, (mostly) in the context of developing countries. Grossman is the the founder and co-director of Penn’s Development Research Initiative (PDRI-DevLab), launched in 2020. At Penn, he is also a Faculty Affiliate at The Center for the Study of Ethnicity, Race, and Immigration Study (CSERI), a member of Wharton’s Lauder Graduate Group in International Studies, and an advisory board member of the Penn Center for Social Norms and Behavioral Dynamics.

Leigh Sterns

Leigh Stearns

Professor, Graduate Chair Penn Arts & Sciences, Dept of Earth & Environmental Science

Leigh Sterns, PhD, is interested in how a changing climate impacts the cryosphere, and the risks associated with those changes. Her current research focuses on ice sheet dynamics and sea level rise, shifts in iceberg and sea ice distributions in Arctic shipping lanes, and glacier loss and water availability at low latitudes. She relies on a combination of satellite remote sensing, machine learning, and geophysical instrumentation to better understand these systems and parameterize their changes into numerical models.

Michael Weisberg

Michael Weisberg

Bess W. Heyman President's Distinguished Professor of Philosophy, Deputy Director of Perry World House School of Arts and Sciences

A climate diplomat, philosopher of science, climate policy researcher, and experienced academic leader, he has worked to negotiate and achieve collective outcomes in the complex landscape of climate, ocean, and development issues at the highest levels of international diplomacy.

An expert on the climate needs of small island developing states, Weisberg currently serves as senior advisor to Jamaica's Permanent Representative to the United Nations and as an advisor to the Fiji and Palau negotiating teams at COP. Weisberg was a leading voice in the development of the "mosaic of solutions" for addressing loss and damage due to the adverse impacts of climate change, which led to major breakthroughs on the topic at COP27 and COP28. This framework was developed in collaboration with the Maldivian Government and the International Peace Institute, where he is a Non-resident Senior Advisor. 

Weisberg serves as editor-in-chief of Biology and Philosophy and director of the Galápagos Education and Research Alliance. He is the author of Simulation and Similarity: Using Models to Understand the World, co-author of the landmark photographic study Galápagos: Life in Motion, and a contributing author to the Intergovernmental Panel on Climate Change's Sixth Assessment Report. He is a member of the Council on Foreign Relations.

Dorit Aviv

Weitzman School of Design Assistant Professor of Architecture

Dorit Aviv, PhD, AIA is Assistant Professor of Architecture at the University of Pennsylvania’s Weitzman School of Design, where she directs the Thermal Architecture Lab, an interdisciplinary laboratory focused on the intersection of thermodynamics, architectural design, and material science. Her work examines how architectural materials and forms can impact airflows, energy interactions, and human health. She is a licensed architect and holds a PhD in architectural technology from Princeton University. Her current projects include a distributed environmental sensing network, development of radiative cooling for hot-humid climates, a combined evaporative and radiative cooling prototype for desert climate, and indoor environmental quality control and assessment technologies.

Steve Decina

Steve Decina

Executive Director - Office of the Vice Provost for Climate Science, Policy, and Action Penn Climate

Stephen Decina, PhD, is the Executive Director of Penn Climate, Penn's whole-of-campus effort to accelerate solutions to the climate crisis. He has had a varied and expansive career, which started as a middle school science teacher in Newark, New Jersey - still the most impactful and important work he has ever done. He got a PhD in biogeochemistry at Boston University and just left his work in the U.S. Department of State where he negotiated environmental agreements at the G7, G20, and the United Nations to come to Penn. He is deeply committed to building community, engaging and mentoring youth, spending as much time in nature as possible, and to being a dad to his two-year old. He recently acquired land and an old stone ruin in his family's ancestral town in Italy which he hopes to rehabilitate using traditional skills and regenerative agriculture.

Jen Wilcox

Jennifer Wilcox

School of Engineering and Applied Science, Kleinman Center for Energy Policy Presidential Distinguished Professor of Chemical Engineering and Energy Policy

Jennifer Wilcox is Presidential Distinguished Professor of Chemical Engineering and Energy Policy at the University of Pennsylvania, with a home at the Kleinman Center for Energy Policy and the School of Engineering and Applied Science. At Penn, she oversees the Clean Energy Conversions Lab.

Wilcox is also a senior fellow at the World Resources Institute, where she leverages her expertise to help accelerate policy support and investments in research, development, and deployment of industrial decarbonization and carbon removal solutions in order to achieve net-zero emissions by 2050. 

Most recently, Wilcox served as Principal Deputy Assistant Secretary for the Office of Fossil Energy and Carbon Management at the Department of Energy. Before coming to Penn, she was the James H. Manning Chaired Professor of Chemical Engineering at Worcester Polytechnic Institute.
