Even in the absence of earthquakes, the venerable seismograph still records tiny deflections of the needle as that familiar roll of paper glides through. Once considered random fluctuations, geophysicists now say that atmospheric disturbances at sea are the cause of this noise, enabling seismic records to be used to expand our historical knowledge of past storms, potentially settling the global warming debate.
