TLDR
A solar forcing mechanism therefore may underlie at least the Holocene segment of the North Atlantic's “1500-year” cycle, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.Abstract:
Surface winds and surface ocean hydrography in the subpolar North Atlantic appear to have been influenced by variations in solar output through the entire Holocene. The evidence comes from a close correlation between inferred changes in production rates of the cosmogenic nuclides carbon-14 and beryllium-10 and centennial to millennial time scale changes in proxies of drift ice measured in deep-sea sediment cores. A solar forcing mechanism therefore may underlie at least the Holocene segment of the North Atlantic's "1500-year" cycle. The surface hydrographic changes may have affected production of North Atlantic Deep Water, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.read more

Response of humification degree to monsoon climate during the Holocene from the Hongyuan peat bog, eastern Tibetan Plateau
TL;DR: In this article, the absorbance value time series of the alkali-extraction of Hongyuan peat from the eastern Tibetan Plateau is determined, and it is used as the proxy indicator for the humification degree of peat.

Haiwei Zhang,Haiwei Zhang,Hai Cheng,Hai Cheng,Yanjun Cai,Yanjun Cai,Christoph Spötl,Gayatri Kathayat,Ashish Sinha,R. Lawrence Edwards,Liangcheng Tan,Liangcheng Tan +11 more
TL;DR: In this paper, a high-resolution record of monsoon precipitation between 5.3 and 3.57 was presented, based on a stalagmite from Shennong Cave, Jiangxi Province, southeast China.
Journal ArticleDOI
A Holocene North Atlantic SST record and regional climate variability
TL;DR: In this article, the authors used 210 Pb dates, identification of Icelandic tephras of known age, and wiggle matching of 14 C radiocarbon dates, and exceptional accurate chronologies have been established for two cores (P1003MC and SC) raised from the same location on the Norwegian continental margin and that span the last 8.ka.
Journal ArticleDOI
Cyclic climate fluctuations during the last interglacial in central Europe
TL;DR: In this paper, the authors show that natural cyclic changes in winter climates affected central European environments during the last interglacial, i.e., the Eemian, 126-110 ka.

Douglas G. Martinson,Nicklas G Pisias,James D. Hays,John Imbrie,Theodore C. Moore,Nicholas J Shackleton +5 more
TL;DR: Using the concept of "orbital tuning", a continuous, high-resolution deep-sea chronostratigraphy has been developed spanning the last 300,000 yr as mentioned in this paper.

A Pervasive Millennial-Scale Cycle in North Atlantic Holocene and Glacial Climates
Gerard C. Bond,William J. Showers,Maziet Cheseby,Rusty Lotti,Peter Almasi,Peter B deMenocal,Paul Priore,Heidi Cullen,Irka Hajdas,Georges Bonani +9 more
TL;DR: In this paper, the North Atlantic deep sea cores reveal that abrupt shifts punctuated what is conventionally thought to have been a relatively stable Holocene climate, and they make up a series of climate shifts with a cyclicity close to 1470 ± 500 years, which is the most recent manifestation of a pervasive millennial-scale climate cycle operating independently of the glacial-interglacial climate state.

Revised carbonate-water isotopic temperature scale
TL;DR: The relationship between temperature and O(18) content relative to that for a Cretaceous belemnite of the Pee Dee formation previously reported (Epstein, Buchsbaum, Lowenstam, and Urey, 1951) has been re-determined using modified procedures for removing organic matter from shells, and is found to be 16.5 - 4.3 δ + 0.14 δ^2
