Persistent Solar Influence on North Atlantic Climate During the Holocene

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.

The holocene Asian monsoon : links to solar changes and North Atlantic climate

TL;DR: A 5-year-resolution absolute-dated oxygen isotope record from Dongge Cave, southern China, provides a continuous history of the Asian monsoon over the past 9000 years, and shows that some, but not all, of the monsoon variability at these frequencies results from changes in solar output.

Global temperature change.

TL;DR: Comparison of measured sea surface temperatures in the Western Pacific with paleoclimate data suggests that this critical ocean region is approximately as warm now as at the Holocene maximum and within ≈1°C of the maximum temperature of the past million years.

Mid- to Late Holocene climate change: an overview

TL;DR: The authors used selected proxy-based reconstructions of different climate variables, together with state-of-the-art time series of natural forcings (orbital variations, solar activity variations, large tropical volcanic eruptions, land cover and greenhouse gases), underpinned by results from GCMs and Earth System Models of Intermediate Complexity (EMICs), to establish a comprehensive explanatory framework for climate changes from the mid-Holocene (MH) to pre-industrial time.

A high-resolution, absolute-dated Holocene and deglacial Asian monsoon record from Dongge Cave, China

TL;DR: In this paper, the authors present a continuous record of the Asian monsoon over the last 16 ka from δ18O measurements of stalagmite calcite, which is combined with a chronology from 45 precise 230Th dates.

The thermohaline circulation of the Arctic Ocean and the Greenland Sea

TL;DR: The thermohaline circulation of the Arctic Ocean and the Greenland Sea is conditioned by the harsh, high latitude climate and by bathymetry as discussed by the authors, which leads to rapid cooling of the surface water and to ice formation.

Atmospheric radiocarbon during the Younger Dryas: production, ventilation, or both?

TL;DR: In this paper, the authors examined results from a large number of simulations (300) based on a zonally averaged ocean circulation model, to constrain the effect on v 14 Catm of PCˇ14 changes during the Younger Dryas cold event (YD) as reconstructed from a Greenland ice core record of 10 Be flux.
