When Juan Hernandez moved to West Oakland from Bakersfield, Calif., one year ago, his asthma flared up. He used his inhaler more and more often and, eventually, had to give up his favorite sport: running. “I was huffing and puffing, but I thought, It’s my own personal problem,” says Hernandez, 17. Then, while working on a school assignment, he discovered otherwise. His environmental-law teacher sent Hernandez and his classmates on a “toxic tour” of their neighborhood: they walked around and wrote down what they saw, what they smelled and how they felt. This particular section of West Oakland, which lies in the shadow of a tangled web of four freeways and the Port of Oakland, has the second highest rate of asthma in the city. As Hernandez strode a few blocks from school, he passed a scrap-metal recycling plant and aluminum smelter that “smelled nasty,” he says. It was an “aha” moment: “I said to myself, ‘I’m living in this place that has some of the worst pollution in all of Oakland, and I gotta do something about it’.”

Understanding the scope and speed of climate change is a formidable problem for modern climate scientists. One way they approach this is to use historical observations of climate to generate computer models of the global climate system. Such models are essential for the prediction of future climate change and the need for them is now particularly acute because of concerns about the speed of global warming: climate scientists need as much data as possible about past climate, and they need it now.
Much work has been done on historical climate data from terrestrial sources, such as the observatories at Greenwich, Edinburgh and Kew, the archives of National Meteorological Services, private institutions and individuals who kept climate data for their own research. Historical marine data has also been used extensively. However, the more data that goes into the models the better the results. Recently it has become evident that ships’ logs could be an excellent source for that data.
