Weather control. Juxtaposing those two words is enough to raise eyebrows in a world where even the best weather models still fail to nail every forecast, and when the effects of climate change on sea level height, seasonal averages of weather phenomena, and biological behavior are being watched with interest by all, regardless of political or scientific persuasion. But between the late nineteenth century—when the United States first funded an attempt to “shock” rain out of clouds—and the late 1940s, rainmaking (as it had been known) became weather control. And then things got out of control. In Make It Rain, Kristine C. Harper tells the long and somewhat ludicrous history of state-funded attempts to manage, manipulate, and deploy the weather in America. Harper shows that governments from the federal to the local became helplessly captivated by the idea that weather control could promote agriculture, health, industrial output, and economic growth at home, or even be used as a military weapon and diplomatic tool abroad. Clear fog for landing aircraft? There’s a project for that. Gentle rain for strawberries? Let’s do it! Enhanced snowpacks for hydroelectric utilities? Check. The heyday of these weather control programs came during the Cold War, as the atmosphere came to be seen as something to be defended, weaponized, and manipulated. Yet Harper demonstrates that today there are clear implications for our attempts to solve the problems of climate change.

Using newly declassified documents, this book explores why U.S. military leaders after World War II sought to monitor the far north and understand the physical environment of Greenland, a crucial territory of Denmark. It reveals a fascinating yet little-known realm of Cold War intrigue and a delicate diplomatic duet between a smaller state and a superpower amid a time of intense global pressures. Written by scholars in Denmark and the United States, this book explores many compelling topics. What led to the creation of the U.S. Thule Air Base in Greenland, one of the world's largest, and why did the U.S. build a nuclear-powered city under Greenland's ice cap? How did Danish concern about sovereignty shape scientific research programs in Greenland? Also explored here: why did Denmark's most famous scientist, Inge Lehmann, became involved in research in Greenland, and what international reverberations resulted from the crash of a U.S. B-52 bomber carrying four nuclear weapons near Thule in January 1968?
