<p><b>How technological advances and colonial fears inspired utopian geoengineering projects during the late nineteenth and early twentieth centuries </b><br><br>From the 1870s to the mid-twentieth century, European explorers, climatologists, colonial officials, and planners were avidly interested in large-scale projects that might actively alter the climate. Uncovering this history, <i>Desert Edens</i> looks at how arid environments and an increasing anxiety about climate in the colonial world shaped this upsurge in ideas about climate engineering. From notions about the transformation of deserts into forests to Nazi plans to influence the climates of war-torn areas, Philipp Lehmann puts the early climate change debate in its environmental, intellectual, and political context, and considers the ways this legacy reverberates in the present climate crisis.<br><br>Lehmann examines some of the most ambitious climate-engineering projects to emerge in the late nineteenth and early twentieth
