Ice Age Terminations
Abstract
Monsoon Cave Recordings: Rocky deposits in caves in central China record the changes over time in the Asian Monsoon through the oxygen isotopic composition of the minerals from which they are formed. These deposits can be precisely dated and provide an absolute time line for climate system changes. Cheng et al. (p. 248 ; see the Perspective by Severinghaus ) present oxygen isotope data from speleothems collected from Sanbao Cave, China, for the three glacial terminations that occurred between 120,000 and 350,000 years ago. The data reveal variations in the amount of precipitation delivered by the Asian Monsoon over time. Comparison of the timing of these changes with corresponding changes in ice core and marine sedimentary records provides mechanistic insights into how variations in insolation affect ice sheets and ice age terminations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
