A High-Resolution Absolute-Dated Late Pleistocene Monsoon Record from Hulu Cave, China

TLDR
The record links North Atlantic climate with the meridional transport of heat and moisture from the warmest part of the ocean where the summer East Asian Monsoon originates and generally agrees with the timing of temperature changes from the Greenland Ice Sheet Project Two (GISP2).
Abstract
Oxygen isotope records of five stalagmites from Hulu Cave near Nanjing bear a remarkable resemblance to oxygen isotope records from Greenland ice cores, suggesting that East Asian Monsoon intensity changed in concert with Greenland temperature between 11,000 and 75,000 years before the present (yr. B.P.). Between 11,000 and 30,000 yr. B.P., the timing of changes in the monsoon, as established with 230Th dates, generally agrees with the timing of temperature changes from the Greenland Ice Sheet Project Two (GISP2) core, which supports GISP2's chronology in this interval. Our record links North Atlantic climate with the meridional transport of heat and moisture from the warmest part of the ocean where the summer East Asian Monsoon originates.

The IntCal20 Northern Hemisphere Radiocarbon Age Calibration Curve (0-55 cal kBP)

Paula J. Reimer, +45 more
- 12 Aug 2020 - 
TL;DR: In this article, the international 14C calibration curves for both the Northern and Southern Hemispheres, as well as for the ocean surface layer, have been updated to include a wealth of new data and extended to 55,000 cal BP.

The Last Glacial Maximum.

TL;DR: The responses of the Northern and Southern Hemispheres differed significantly, which reveals how the evolution of specific ice sheets affected sea level and provides insight into how insolation controlled the deglaciation.

The holocene Asian monsoon : links to solar changes and North Atlantic climate

TL;DR: A 5-year-resolution absolute-dated oxygen isotope record from Dongge Cave, southern China, provides a continuous history of the Asian monsoon over the past 9000 years, and shows that some, but not all, of the monsoon variability at these frequencies results from changes in solar output.

Millennial- and orbital-scale changes in the East Asian monsoon over the past 224,000 years

TL;DR: An absolute-dated oxygen isotope record from Sanbao cave, central China, is presented that completes a Chinese-cave-based record of the strength of the East Asian monsoon that covers the past 224,000 years, supporting the idea that tropical/subtropical monsoons respond dominantly and directly to changes in Northern Hemisphere summer insolation on orbital timescales.

Evidence for general instability of past climate from a 250-kyr ice-core record

TL;DR: In this paper, the authors present a detailed stable isotope record for the full length of the Greenland Ice-core Project Summit ice core, extending over the past 250 kyr according to a calculated timescale, and find that climate instability was not confined to the last glaciation, but appears also have been marked during the last interglacial (as explored more fully in a companion paper), and during the previous Saale-Holstein glacial cycle.

Correlations between climate records from North Atlantic sediments and Greenland ice

TL;DR: In this article, the authors present records of sea surface temperature from North Atlantic sediments spanning the past 90 kyr which contain a series of rapid temperature oscillations closely matching those in the ice-core record, confirming predictions that the ocean must bear the imprint of the Dansgaard-Oeschger events.

Long-term variations of daily insolation and Quaternary climatic changes

TL;DR: In this paper, a trigonometrical formula for the Earth's orbital elements is presented, which allows direct spectral analysis and the computation of those long-term variations of the orbital elements which are of primary interest for the calculation of the insolation.

Macintosh Program performs time‐series analysis

TL;DR: A Macintosh computer program that can perform many time-series analysis procedures is now available on the Internet free of charge, originally designed for paleoclimatic time series.
