Annually dated ice cores from Siple Dome, West Antarctica, and central Greenland indicate that meridional atmospheric circulation intensity increased in the polar South Pacific and North Atlantic at the beginning (∼1400 A.D.) of the most recent Holocene rapid climate change event, the Little Ice Age (LIA). As deduced from chemical concentrations at these core sites, the LIA was characterized by substantial meridional circulation strength variability, and this variability persists today despite… 

Surface changes in the North Atlantic meridional overturning circulation during the last millennium

TLDR
Water mass tracer data presented here from the North Icelandic shelf, combined with previously published data from the Arctic and subtropical Atlantic, show that surface Atlantic meridional overturning circulation dynamics likely amplified the relatively warm conditions during the Medieval Climate Anomaly and the relatively cool conditions within the Little Ice Age within the North Atlantic sector.

Climate and hydrographic variability in the Indo‐Pacific Warm Pool during the last millennium

Planktonic foraminiferal Mg/Ca and δ18O derived sea surface temperature and salinity records from the Makassar Strait, Indonesia, show a long‐term cooling and freshening trend, as well as

Abstract We present highly resolved, annually dated, calibrated proxies for atmospheric circulation from several Antarctic ice cores (ITASE (International Trans-Antarctic Scientific Expedition),

Little Ice Age climate and oceanic conditions of the Ross Sea, Antarctica from a coastal ice core record

Increasing paleoclimatic evidence suggests that the Little Ice Age (LIA) was a global climate change event. Understanding the forcings and associated climate system feedbacks of the LIA is made

Despite the relative climate stability of the present interglacial, it has been punctuated by several centennial time scale climatic oscillations, the latest of which are often colloquially referred

340 years of atmospheric circulation characteristics reconstructed from an eastern Antarctic Peninsula ice core

Precipitation delivery mechanisms for Dolleman Island (DI), located off the east coast of the Antarctic Peninsula, are investigated using reanalysis and back trajectory data. The Southern Annular

RAPID CLIMATE CHANGE IN THE TROPICAL AMERICAS DURING THE LATE- GLACIAL INTERVAL AND THE HOLOCENE

Till deposits, related to advances of mountain glaciers, and lake sediments record periods of abrupt warming and cooling during the Late Glacial interval (LG) (17,500 to 11,650 cal yr BP) in the

TLDR
The analyses of two ice cores from a southern tropical ice cap provide a record of climatic conditions over 1000 years for a region where other proxy records are nearly absent and confirms the worldwide character of the Little Ice Age.

TLDR
Sulfate concentrations from continuous biyearly sampling of the GISP2 Greenland ice core provide a record of potential climate-forcing volcanism since 7000 B.C. with sulfate deposition equal to or up to five times that of the largest known historical eruptions.
