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

Holocene oscillations in temperature and salinity of the surface subpolar North Atlantic
TL;DR: This paper investigated the temperature and salinity changes of a substantial surface inflow to a region of deepwater formation throughout the Holocene and found that the inflow has undergone millennial-scale variations in temperature, most probably controlled by subpolar gyre dynamics.

Inverse phase oscillations between the East Asian and Indian Ocean summer monsoons during the last 12 000 years and paleo-El Niño
Yetang Hong,Bing Hong,Q.H. Lin,Yasuyuki Shibata,Masashi Hirota,Y.X. Zhu,X.T. Leng,Yetang Wang,Hailong Wang,Liang Yi +9 more
TL;DR: In this article, the inverse phase variations between the East Asian and Indian Ocean summer monsoons on the interannual timescale result from the El Nino-Southern Oscillation activity in the tropical Pacific, which provides a new way for studying paleo-ENSO.

Medieval Warm Period, Little Ice Age and 20th century temperature variability from Chesapeake Bay
TL;DR: Paleoclimate evidence for rapid (<100 years) shifts of f2-4 jC in Chesapeake Bay (CB) temperature f2100, 1600, 950, 650, 400 and 150 years before present (years BP) reconstructed from magnesium/calcium (Mg/Ca) paleothermometry is presented in this paper.

Reconstruction of temperature in the Central Alps during the past 2000 yr from a δ18O stalagmite record
TL;DR: In this article, the precisely dated isotopic composition of a stalagmite from Spannagel Cave in the Central Alps is translated into a highly resolved record of temperature at high elevation during the past 2000 yr.

Cyclic rapid warming on centennial‐scale revealed by a 2650‐year stalagmite record of warm season temperature
TL;DR: In this article, a 2650-year (BC665-AD1985) warm season (MJJA: May, June, July, August) temperature reconstruction is derived from a correlation between thickness variations in annual layers of a stalagmite from Shihua Cave, Beijing, China and instrumental meteorological records.

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
