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

Timing and dynamics of the last deglaciation from European and North African δ13C stalagmite profiles—comparison with Chinese and South Hemisphere stalagmites

TL;DR: The last deglaciation and its climatic events such as the Bolling-Allerod (BA) and the Younger Dryas (YD) have been clearly recorded in the δ 13 C profiles of three stalagmites from caves from Southern France to Northern Tunisia.

Millennial‐scale temperature variations in North America during the Holocene
TL;DR: In this paper, a mean continental July temperature reconstruction based on pollen records from across North America quantifies temperature variations of several timescales for the past 14,000 cal yr BP.

A high‐resolution study of Holocene paleoclimatic and paleoceanographic changes in the Nordic Seas
Bjørg Risebrobakken,Eystein Jansen,Eystein Jansen,Eystein Jansen,Carin Andersson,Eirik Mjelde,Kjersti Hevroy,Kjersti Hevroy +7 more
TL;DR: In this article, high-resolution records from IMAGES core MD95-2011 in the eastern Norwegian Sea provide evidence for relatively large and small-scale high-latitude climate variability throughout the Holocene.

Evidence for solar forcing on the Indian monsoon during the last millennium
TL;DR: In this article, the authors used a sediment core from the eastern Arabian Sea dating back to 1200 yr, through pattern matching as well as spectral analysis of proxy records of monsoon and solar activity.

Precise timing and characterization of abrupt climate change 8200 years ago from air trapped in polar ice
Takuro Kobashi,Jeffrey P. Severinghaus,Edward J. Brook,Jean-Marc Barnola,Alexi M. Grachev,Alexi M. Grachev +5 more
TL;DR: Legrande et al. as mentioned in this paper analyzed the evolution of the 8.2 ka climate change and found that the change was a synchronous event within 74 years at a hemispheric scale.

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
