Book excerpt: "If you want to understand the long path to the climate crisis, read this book." –Deborah Coen, Professor of History and the History of Science and Medicine, Yale University Politicians and scientists have debated climate change for centuries in times of rapid change Nothing could seem more contemporary than climate change. Yet, in Chaos in the Heavens, Jean-Baptiste Fressoz and Fabien Locher show that we have been thinking about and debating the consequences of our actions upon the environment for centuries. The subject was raised wherever history accelerated: by the Conquistadors in the New World, by the French revolutionaries of 1789, by the scientists and politicians of the nineteenth century, by the European imperialists in Asia and Africa until the Second World War. Climate change was at the heart of fundamental debates about colonisation, God, the state, nature, and capitalism. From these intellectual and political battles emerged key concepts of contemporary environmental science and policy. For a brief interlude, science and industry instilled in us the reassuring illusion of an impassive climate. But, in the age of global warming, we must, once again, confront the chaos in the heavens.
