The similarity of this pattern \r\nto that of CH4 records from polar ice cores indicates that global \r\nCH4 levels and the tropical hydrological cycle are linked. \r\nThe Late Glacial Stage record contains numerous 200-year \r\noscillations in d18O values and in dust, NH4+, and NO3- levels.\r\n","author":null,"citation":"Thompson, L.G., T.
