Journal ArticleDOI
Global temperature change.
TL;DR: Comparison of measured sea surface temperatures in the Western Pacific with paleoclimate data suggests that this critical ocean region is approximately as warm now as at the Holocene maximum and within ≈1°C of the maximum temperature of the past million years.
Journal ArticleDOI
Climate Impact of Late Quaternary Equatorial Pacific Sea Surface Temperature Variations
TL;DR: Comparison of SST estimates from eastern and western sites indicates that the equatorial Pacific zonal SST gradient was similar or somewhat larger during glacial episodes, and extraction of a salinity proxy from the magnesium/calcium and oxygen isotope data indicates that transport of water vapor into the western Pacific was enhanced duringglacial episodes.
Journal ArticleDOI
Reevaluation of the oxygen isotopic composition of planktonic foraminifera: Experimental results and revised paleotemperature equations
TL;DR: In this paper, Orbulina universa and Globigerina bulloides were used to reexamine temperature:δ18O relationships at 15°-25°C.
Journal ArticleDOI
Variability in the El Niño-Southern Oscillation Through a Glacial-Interglacial Cycle

TL;DR: Annual banded corals from Papua New Guinea are used to show that ENSO has existed for the past 130,000 years, operating even during “glacial” times of substantially reduced regional and global temperature and changed solar forcing, and it is found that during the 20th century ENGSO has been strong compared with E NSO of previous cool and warm times.
Journal ArticleDOI
Effect of seawater carbonate concentration on foraminiferal carbon and oxygen isotopes
TL;DR: In this paper, the authors reported experimental measurements on living symbiotic and non-symbiotic plankton foraminifera (Orbulina universa and Globigerina bulloides respectively) showing that the 13C/12C and 18O/16O ratios of the calcite shells decrease with increasing seawater [CO32−].
