Previously, we demonstrated that the annual d18O variations reflect those  in sea-surface temperature (SST), while the annual d13C variations record  primarily cloud-cover changes.  We apply two distinct spectral analysis methods  to the d13C and d18O time series from 1853 to 1989. Our analysis of the d18O  record shows a secular warming trend and a 35-year oscillation in temperatures  over the last 137 years. A trend and a 34-year cycle are also found in the  d13C record. The latter trend may be caused by either anthropogenic effects or a cloud-cover increase in this region of the Pacific Ocean, while the  interdecadal oscillation appears to be related to changes in cloud cover,  as well as in precipitation.","author":{"name":"Boiseau, M.; Ghil, M.; Juillet-Leclerc, A"},"citation":"Boiseau, M.; Ghil, M.; Juillet-Leclerc, A. 1999.
