Climate Science

April 8 - December 31, 2022
104 S. 5th Street, Philadelphia, PA 19106

An exhibition on the History of Climate Science is scheduled to open at the American Philosophical Society Library & Museum in 2022. It will explore the questions and methods that have driven the study of weather and climate in the Western world from the mid-eighteenth century through today. The exhibition will highlight the importance of work by amateurs and professionals who have worked collaboratively to study weather and climate in the interest of agriculture, human health and comfort, military dominance, and simple curiosity. In addition, the exhibition will consider how ideas about climate and weather have changed over time. This exhibition will expose visitors to the rich history of climate study, the rigor of current science, and the many possibilities for non-scientists to contribute to a more sustainable global climate – and the surprising and often-overlooked role the APS and its Members have played in these stories.
