The Papers of Thomas Jefferson and the Record of Past Climate Change

In the 19th episode of Climate History, co-hosts Dagomar Degroot and Emma Moesswilde discuss their work on a major article in the journal Nature. The article coins a new term – the “History of Climate and Society” (HCS) – to refer to the truly interdisciplinary study of the past impacts of climate change on human populations. It offers a detailed critique of the field as it has been pursued to date, presents a new research framework for HCS scholars, and shows how the application of that framework can permit new scholarship into the resilience and adaptability of populations that faced the modest, pre-industrial climate changes of the past 2,000 years. It also identifies five “pathways” that allowed populations to endure and even exploit these changes - pathways from which we might learn today. Dagomar Degroot, lead author of the study, explains what led him to develop the article, describes its major findings, and reveals what it can tell us about the future of global warming.

Making Climate Policy: What's Working, and Where We Should Go Now

In the 17th episode of Climate History, co-hosts Dagomar Degroot and Emma Moesswilde interview PhD candidate Emily Webster of the Department of History at the University of Chicago. Webster's trailblazing scholarship combines environmental history, the history of science, and medical history to transform understandings of disease in the British Empire. Among other topics, Webster discusses what history can reveal about the unequal impacts of environmental change on marginalized communities, and how it can shed light on connections between apparently isolated environmental crises. She also describes how history can inform public discourse on COVID-19; and identifies the impact of our present pandemic on higher education - particularly graduate students.

Pandemics, Empires, and the Lessons of History

In the 16th episode of Climate History, co-hosts Dagomar Degroot and Emma Moesswilde interview professor Timothy Newfield, a climate historian and historical epidemiologist in the departments of history and biology at Georgetown University. Professor Newfield explains how he landed in two very different departments, in two very different fields, and introduces the discipline of historical epidemiology. He describes how historical epidemiologists can identify past diseases and their social consequences, then considers what history can reveal about today's COVID-19 pandemic. Finally, he reflects on the links between climate change and disease, past and present, and on the limitations of public discourse about today's biggest environmental challenges.

Pandemics and Climate Change: What History Tells Us About Today's Greatest Challenges

In the 15th episode of Climate History, co-hosts Dagomar Degroot and Emma Moesswilde interview Kathryn de Luna, Provost's Distinguished Associate Professor in the Department of History at Georgetown University. Professor de Luna combines paleoscience, archaeology, and historical linguistics to explore the deep history of eastern, central and southern Africa before the 20th century. At Georgetown, she is on the cutting edge of developing new courses and teaching methods that introduce students to ways of understanding the past that go well beyond the traditional practice of history. In this episode, Professor de Luna describes the courses she teaches; outlines the potential and peril of multidisciplinary learning; and gives concrete advice for how to make university education truly multidisciplinary.

Teaching Across Disciplines: Reimagining University Education for Today's Multidisciplinary Problems

In the 14th episode of Climate History, co-hosts Dagomar Degroot and Emma Moesswilde interview Joseph Manning, the William K. and Marilyn Milton Simpson Professor of Classics at Yale University. Professor Manning is a leading expert on the law, politics, and economy of the ancient world, particularly the Hellenistic Period (between 330 and 30 BCE). In recent years, he's led efforts to uncover a link between volcanic eruptions, climatic shocks, and rebellions in ancient Egypt: efforts that inspired headlines in the Washington Post, the New York Times, and elsewhere. Professor Manning explains how his team uncovered the influence of climate change in Egyptian history, and what the ancient world has to tell us about our uncertain future.

In the eighth episode of the Climate History Podcast, Georgetown PhD candidate Robynne Mellor interviews Professor Dagomar Degroot (Georgetown University), the co-director of the Climate History Network, about his new book: "The Frigid Golden Age: Climate Change, the Little Ice Age, and the Dutch Republic, 1560-1720" (Cambridge University Press). Mellor and Degroot discuss the so-called "Little Ice Age;" the contrasting experiences of different societies; resilience and adaptation in the face of climate change; the keys to getting a job in environmental history, and the culture shock of moving from Canada to the United States.

The Frigid Golden Age: How the Dutch Republic Thrived as Earth's Climate Changed

In the ninth episode of Climate History, our podcast, we relaunch with a new co-host: Emma Moesswilde, PhD Student in Environmental History at Georgetown University. For the relaunch, Moesswilde and Dagomar Degroot are joined by Kevin Anchukaitis,  associate professor of geography at the University of Arizona and one of the world's leading paleoclimatologists. Anchukaitis uncovers and interprets past climate changes, and he's responsible for some of the most important studies on climatic trends past and present. In this episode, Moesswilde, Degroot, and Anchukaitis discuss how and why Earth's climate has changed over the past two thousand years; how scholars "reconstruct" those changes; how historians can link the changes to the course of human history; why this research matters today; and how to communicate scholarship on past climates to the widest possible audience.

The Past, Present, and Future Significance of Climate Changes Over the Past 2,000 Years

In the 11th episode of Climate History, co-hosts Dagomar Degroot and Emma Moesswilde interview Victoria Herrmann, president and managing director of the Arctic Institute and one of Apolitical's top 100 influencers on climate policy. Dr. Herrmann's scholarship has focused on media representations of the Arctic and its peoples. Yet while completing her PhD as a Gates Scholar in the Scott Polar Institute at Cambridge University, Herrmann launched several projects aimed at building adaptation to climate change in coastal communities. Her focus has been to connect scholars with stakeholders on the ground, turning abstract knowledge into tangible action. In this interview, we discuss how climate change scholarship can (and perhaps should) inform concrete action, and how action can enrich scholarship. We consider how graduate students can find their public voice, weigh the importance of storytelling for encouraging climate change action, and contemplate sources of hope in a rapidly warming world.
