Today, predicting the impact of human activities on the earth’s climate hinges on tracking interactions among phenomena of radically different dimensions, from the molecular to the planetary. Climate in Motion shows that this multiscalar, multicausal framework emerged well before computers and satellites. Extending the history of modern climate science back into the nineteenth century, Deborah R. Coen uncovers its roots in the politics of empire-building in central and eastern Europe. She argues that essential elements of the modern understanding of climate arose as a means of thinking across scales in a state—the multinational Habsburg Monarchy, a patchwork of medieval kingdoms and modern laws—where such thinking was a political imperative. Led by Julius Hann in Vienna, Habsburg scientists were the first to investigate precisely how local winds and storms might be related to the general circulation of the earth’s atmosphere as a whole. Linking Habsburg climatology to the political and artistic experiments of late imperial Austria, Coen grounds the seemingly esoteric science of the atmosphere in the everyday experiences of an earlier era of globalization. Climate in Motion presents the history of modern climate science as a history of “scaling”—that is, the embodied work of moving between different frameworks for measuring the world. In this way, it offers a critical historical perspective on the concepts of scale that structure thinking about the climate crisis today and the range of possibilities for responding to it. 

Earthquakes have taught us much about our planet’s hidden structure and the forces that have shaped it. This knowledge rests not only on the recordings of seismographs but also on the observations of eyewitnesses to destruction. During the nineteenth century, a scientific description of an earthquake was built of stories—stories from as many people in as many situations as possible. Sometimes their stories told of fear and devastation, sometimes of wonder and excitement.
           
In The Earthquake Observers, Deborah R. Coen acquaints readers not only with the century’s most eloquent seismic commentators, including Alexander von Humboldt, Charles Darwin, Mark Twain, Charles Dickens, Karl Kraus, Ernst Mach, John Muir, and William James, but also with countless other citizen-observers, many of whom were women. Coen explains how observing networks transformed an instant of panic and confusion into a field for scientific research, turning earthquakes into natural experiments at the nexus of the physical and human sciences. Seismology abandoned this project of citizen science with the introduction of the Richter Scale in the 1930s, only to revive it in the twenty-first century in the face of new hazards and uncertainties. The Earthquake Observers tells the history of this interrupted dialogue between scientists and citizens about living with environmental risk.
