This very interesting work gives us a solid history of air-conditioning in a broad sense. A timely and urgent work in our doom-laden age of climate change, it encompasses not only the air-conditioning of discrete spaces and rooms but also that of climate-controlled shelters and atmospheric control on a geographic scale. The terms "climate" and "media" as applied in the title do not have the limited meanings generally assumed. Instead, the author analyzes the science and ideas behind air cooling and offers a range of perspectives on how air is controlled, including the chemical and technological conditioning of indoor and outdoor atmospheres. Although the meaning of "climatic media" is not clearly defined—especially the concept of "media," which is rather broad and confusing to outsiders of media studies—the book depicts the history of the air-conditioning of spaces, from narrow rooms to zone shelters to a more extended scale. Therefore, this book is worth reading for historians of science and technology.
