Speleothem evidence from Oman for continental pluvial events during interglacial periods, 2001, Burns Sj, Fleitmann D, Matter A, Neff U, Mangini A,
Growth periods and stable isotope analyses of speleothems from Hoti Cave in northern Oman provide a record of continental pluvial periods extending back over the past four of Earth's glacial-interglacial cycles. Rapid speleothem growth occurred during the early to middle Holocene (6-10.5 ka B.P.), 78-82 ka B.P., 120-135 ka B.P., 180-200 ka B.P., and 300-325 ka B.P. The speleothem calcite deposited during each of these episodes is highly depleted in 18O compared to modern speleothems. The {delta}18O values for calcite deposited within pluvial periods generally fall in the range of -4{per thousand} to -8{per thousand} relative to the Vienna Peedee belemnite standard, whereas modern speleothems range from -1{per thousand} to -3{per thousand}. The growth and isotopic records indicate that during peak interglacial periods, the limit of the monsoon rainfall was shifted far north of its present location and each pluvial period was coincident with an interglacial stage of the marine oxygen isotope record. The association of continental pluvial periods with peak interglacial conditions suggests that glacial boundary conditions, and not changes in solar radiation, are the primary control on continental wetness on glacial-interglacial time scales

Solar forcing of Holocene climate: New insights from a speleothem record, southwestern United States, 2007, Asmerom Y, Polyak V, Burns S, Rassmussen J,
Holocene climate change has likely had a profound influence on ecosystems and culture. A link between solar forcing and Holocene climate, such as the Asian monsoon, has been shown for some regions, although no mechanism for this relationship has been suggested. Here we present the first high-resolution complete Holocene climate record for the North American monsoon region of the southwestern United States (southwest) in order to address the nature and causes of Holocene climate change. We show that periods of increased solar radiation correlate with decreased rainfall, the opposite to that observed in the Asian monsoon, and suggest that a solar link to Holocene climate is through changes in the Walker circulation and the Pacific Decadal Oscillation and El Nino-Southern Oscillation systems of the tropical Pacific Ocean. Given the link between increased warming and aridity in the southwest, additional warming due to greenhouse forcing could potentially lead to persistent hyperarid conditions, similar to those seen in our record during periods of high solar activity
