"Old Weather: our weather's past, the climate's future"

We all care about today's weather, and the prediction for tomorrow's; Old Weather is about yesterday's, last year's, and the previous century's. The history of the weather is vital information for climate science, as it provides context and validation for predictions of climate change, and supports interdisciplinary work between history and science.

Old Weather is an internet crowdsourcing project. Photographs of thousands of ships' logbooks (from the National Archives) are shared, transcribed and analysed by a large group of volunteer researchers. These logbooks tell us not only about the weather, but also the full story of the activities of each ship, detailing coaling, cricket matches, illness, discipline, accidents and even military action. From them we are building a newly detailed picture of both climate variability and marine life.
