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

Increased aeolian activity during humidity shifts as recorded in a raised bog in south-west Sweden during the past 1700 years
TL;DR: In this article, an analysis of testate amoebae and aeolian sediment influx (ASI) was used to reconstruct effective humidity changes and eolian activity in the coastal zone of south-west Sweden.

Early Holocene humidity patterns in the Iberian Peninsula reconstructed from lake, pollen and speleothem records
TL;DR: In this paper, a comparison of selected, well-dated, lacustrine, speleothem and terrestrial pollen records spanning the Holocene onset and the Early Holocene (ca. 11.7-8 cal/kyrs BP) in the Iberian Peninsula shows large hydrological fluctuations and landscape changes with a complex regional pattern in timing and intensity.

Multidecadal to millennial-scale shifts in drought conditions on the Canadian prairies over the past six millennia: implications for future drought assessment
Astrid Michels,Kathleen R. Laird,Susan E. Wilson,David J. Thomson,Peter R. Leavitt,Robert J. Oglesby,Brian F. Cumming +6 more
TL;DR: In this paper, diatom analyses from lake sediment cores from the Canadian prairies were used to show that shifts in drought conditions have prevailed on centennial to millennial time scales for at least the past six millennia.

Solar and tropical ocean forcing of late-Holocene climate change in coastal East Asia
TL;DR: In this paper, the authors extracted high-resolution sediment records from the Mulyoungari swamp on Jeju Island, South Korea and examined them to determine the main factors driving late Holocene climate change in East Asia.

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
