Climate Refugees Through Time Exercise

The lecture explores the long history of human displacement, focusing specifically on refugees (individuals forced to move due to external forces beyond their control). While humans have moved since ancient times, the industrial era ushered in mass migrations driven by systemic vulnerabilities, such as the Irish Potato Famine, where a national-scale monoculture led to catastrophic crop failure. Similarly, environmental disasters like the Dust Bowl in the United States, fueled by drought and poor farming practices, created a massive wave of we would now consider "climate refugees" or "environmental refugees" who used Route 66 as an escape route into the relatively verdant farm fields of California. These historical examples demonstrate that environmental shocks have frequently intersected with social and economic systems to trigger large-scale human movement In the modern era, we've seen a growing disconnect between international legal frameworks and the reality of displacement. Following World War II, the United Nations defined refugees strictly as those fleeing persecution, a definition that largely relegated environmental factors to a footnote as the Cold War raged. This narrow focus continues to influence modern politics, where migration is often framed solely as an economic or political issue, even when environmental triggers are present (e.g. the droughts that preceded the Arab Spring and the Syrian revolution). We wrap with an acknowledgment that climate change as a major driver of displacement is crucial for creating proactive and equitable policies, rather than waiting for displacement to reach a "time critical crisis."
