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

Simulating the Holocene climate evolution at northern high latitudes using a coupled atmosphere-sea ice-ocean-vegetation model
TL;DR: In this paper, the response of the climate at high northern latitudes to slowly changing external forcings was studied in a 9,000-year long simulation with the coupled atmosphere-sea ice-ocean-vegetation model ECBilt-CLIO-VECODE.
Journal ArticleDOI
Millennial-scale storminess variability in the northeastern United States during the Holocene epoch
TL;DR: The data show four peaks in storminess during the past 14 kyr, consistent with long-term changes in the average sign of the Arctic Oscillation, suggesting that modulation of this dominant atmospheric mode may account for a significant fraction of Holocene climate variability in North America and Europe.

Drought and Aquatic Ecosystems: Effects and Responses
TL;DR: The nature of Droughts and their assessment can be found in this article, where the authors discuss water bodies, catchments, and the abiotic effects of drought, as well as the human-induced exacerbation of Drought Effects on Aquatic Ecosystems.

Hydrologic variation during the last 170,000 years in the southern hemisphere tropics of South America
Sherilyn C. Fritz,Paul A. Baker,Tim K. Lowenstein,Geoffrey O. Seltzer,Catherine A. Rigsby,Gary S. Dwyer,Pedro M. Tapia,Kimberly K. Arnold,Teh-Lung Ku,Shangde Luo +9 more
TL;DR: This article presented a well-dated 170,000-year time series of hydrologic variation from the southern hemisphere tropics of South America that extends from modern times through most of the penultimate glacial period.

Model–data comparison for the 8.2 ka BP event: Confirmation of a forcing mechanism by catastrophic drainage of Laurentide Lakes.
A.P. Wiersma,Hans Renssen +1 more
TL;DR: In this paper, the authors compare proxy evidence with climate model simulations in which the thermohaline ocean circulation is perturbed by a freshwater pulse into the Labrador Sea, showing a cooling that is mainly concentrated in the North Atlantic region.

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
