This thesis examines perceptions of climate change in literature through the lens of the environmental humanities, an interdisciplinary field that brings history, ecocriticism, and anthropology together to consider the environmental past, present and future. The project began in Iceland, during the Svartárkot Culture-Nature Program called “Human Ecology and Culture at Lake Mývatn 1700-2000: Dimensions of Environmental and Cultural Change”. Over the course of 10 days, director of the program, Viðar Hreinsson, an acclaimed literary and Icelandic Saga scholar, brought in researchers from different fields of study in Iceland to give students a holistically academic approach to their own environmental research. In this thesis, texts under consideration include the Icelandic Sagas, My Antonia by Willa Cather, Tropic of Orange by Karen Tei Yamashita, and The Water Knife by Paolo Bacigalupi. The thesis is supported by secondary works written by environmental humanists, including Andrew Ross, Steve Hartman, Ignacio Sanchez Cohen, and Joni Adamson, who specialize in archeological research on heritage sites in Iceland and/or study global weather patterns, prairie ecologies in the American Midwest, the history of water in the Southwest, and climate fiction. Chapter One, focusing on the Icelandic Sagas and My Antonia, argues that literature from different centuries, different cultures, and different parts of the world offers evidence that humans have been driving environmental degradation at the regional and planetary scales since at least the 1500s, especially as they have engaged in aggressive forms of settlement and colonization. Chapter Two, focused on Tropic of Orange, this argues that global environmental change leads to extreme weather and drought that is increasing climate migration from the Global South to the Global North. Chapter Three, focused on The Water Knife, argues that climate fiction gives readers the opportunity to think about and better prepare for a viable and sustainable future rather than wait for inevitable apocalypse. By exploring literature that depicts and represents climate change through time, environmental humanists have innovated new methods of analysis for teaching and thinking about what humans must understand about their impacts on ecosystems so that we can better prepare for the future.
