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

TL;DR: In this article, high-resolution evidence from anoxic (unbioturbated) sediments in the eastern Mediterranean Sea that demonstrates a sustained ∼800-yr climate disturbance in the monsoonal latitudes during the Eemian interglacial maximum (∼125 ka BP) was presented.

Palaeo-oceanography: Deepwater variability in the Holocene epoch
TL;DR: Investigation of changes in the carbon-isotope composition of benthic foraminifera throughout the Holocene finds that deep-water production varied on a centennial–millennial timescale, which may hint at a contribution to climate change over this period.

Large variations in Holocene solar activity: Constraints from 10Be in the Greenland Ice Core Project ice core
TL;DR: In this paper, the solar activity in terms of the heliospheric modulation function was quantitatively reconstructed in high resolution throughout the Holocene by using the 10Be data from the Greenland Ice Core Project ice core as well as 14C support a high current solar activity.

Volcanic and Solar Forcing of Climate Change during the Preindustrial Era
TL;DR: In this article, the climate response to variability in volcanic aerosols and solar irradiance, the primary forcings during the preindustrial era, is examined in a stratosphere-resolving general circulation model.

Climate Time Series Analysis: Classical Statistical and Bootstrap Methods
TL;DR: In this article, the authors introduce persistence models and Bootstrap Confidence Intervals for univariate and bivariate time series analysis, and present a future direction for future directions. But, they do not discuss the use of spectral analysis.

A Pervasive Millennial-Scale Cycle in North Atlantic Holocene and Glacial Climates

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

TL;DR: The most prominent Holocene climatic event in Greenland ice-core proxies, with approximately half the amplitude of the Younger Dryas, occurred ∼8000 to 8400 yr ago.
