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

Global atmospheric particle formation from CERN CLOUD measurements
TL;DR: A global model of aerosol formation is built by using extensive laboratory measurements of rates of nucleation involving sulfuric acid, ammonia, ions, and organic compounds conducted in the CERN CLOUD chamber and shows that nearly all nucleation throughout the present-day atmosphere involves ammonia or biogenic organic compounds.

Multiproxy late Holocene peat records from Ireland: towards a regional palaeoclimate curve
TL;DR: In this paper, two peat-based climate records from Ireland covering the late Holocene are presented, and the sequences are dated by a strong chronological framework formed by AMS radiocarbon dates and SCPs.

Evidence for an extreme climatic event on Achill Island, Co. Mayo, Ireland around 5200–5100 cal. yr BP
TL;DR: A range of detailed palaeoenvironmental analyses carried out on a series of three peat profiles from Achill Island, Co Mayo, western Ireland, reveal evidence for an extreme climatic event, probably a storm or series of storms, around 5200-5100 cal yr BP that caused the deposition of an extensive layer of silt across blanket peat as discussed by the authors.

Solar and planetary oscillation control on climate change: hind-cast, forecast and a comparison with the CMIP5 GCMs
TL;DR: In this article, an empirical model is proposed that uses a specific set of decadal, multidecadal, secular and millennial astronomic harmonics to simulate the observed climatic oscillations.

Age dating and the orbital theory of the ice ages: Development of a high-resolution 0 to 300,000-year chronostratigraphy
Douglas G. Martinson,Nicklas G Pisias,James D. Hays,John Imbrie,Theodore C. Moore,Nicholas J Shackleton +5 more
TL;DR: Using the concept of "orbital tuning", a continuous, high-resolution deep-sea chronostratigraphy has been developed spanning the last 300,000 yr as mentioned in this paper.

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
