title: Atmospheric carbon dioxide, the southern oscillation, and the weak 1975 el nino.
abstract: The observed rate of change of the atmospheric carbon dioxide concentration at the South Pole, Fanning Island, Hawaii, and ocean weather station P correlates with an index of the southern oscillation and with El Niño occurrences. There are changes at all four stations that seem to be in response to the weak 1975 El Niño. Thus, even poorly developed El Niño events may affect the atmospheric carbon dioxide concentration.
