"What can yesterday's weather tell us about how the climate is changing today? That's what an army of volunteers looking at old ships' logs is trying to answer through the Old Weather project."

"One of those volunteers — or citizen scientists, as the project calls them — is Kathy Wendolkowski of Gaithersburg, Md."

"Sitting in her kitchen, she uses her laptop to read from the logbook of the Pioneer, a ship that was out measuring ocean depths near Alaska on July 15, 1925. An image of the Pioneer's log from that day was posted online by the National Archives at the website OldWeather.org. Her task is to transcribe the logs' handwritten notes, from their elegant cursive script to something that can be digested by computers."
