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… Expand
Climate and hydrographic variability in the Indo‐Pacific Warm Pool during the last millennium
Planktonic foraminiferal Mg/Ca and delta O-18 derived sea surface temperature and salinity records from the Makassar Strait, Indonesia, show a long-term cooling and freshening trend, as well asExpand
Surface changes in the North Atlantic meridional overturning circulation during the last millennium
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.

Solar forcing of the polar atmosphere
Abstract We present highly resolved, annually dated, calibrated proxies for atmospheric circulation from several Antarctic ice cores (ITASE (International Trans-Antarctic Scientific Expedition),Expand
Isotopic evidence for hydrologic change related to the westerlies in SW Patagonia, Chile, during the last millennium
Abstract The Southern Hemisphere westerly winds influence the spatial distribution of precipitation in southern South America and play a significant role in the global carbon cycle, yet little isExpand
Cold conditions in Antarctica during the Little Ice Age — Implications for abrupt climate change mechanisms
Abstract The Little Ice Age (LIA) is one of the most prominent climate shifts in the past 5000 yrs. It has been suggested that the LIA might be the most recent of the Dansgaard–Oeschger events, whichExpand
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 madeExpand
340 years of atmospheric circulation characteristics reconstructed from an eastern Antarctic Peninsula ice core
[1] 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 AnnularExpand
Surface changes in the eastern Labrador Sea around the onset of the Little Ice Age
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 referredExpand
Late-Holocene diatom derived seasonal variability in hydrological conditions off Disko Bay, West Greenland
Abstract A decadally resolved diatom record from a sediment core collected from Disko Bay, central West Greenland, reveals variations in hydrological conditions for the late Holocene. The diatomExpand
Late Holocene change in climate and atmospheric circulation inferred from geochemical records at Kepler Lake, south-central Alaska
Climate records during the last millennium are essential in placing recent anthropogenic-induced climate change into the context of natural climatic variability. However, detailed records are stillExpand


The Little Ice Age and Medieval Warm Period in the Sargasso Sea
Sea surface temperature (SST), salinity, and flux of terrigenous material oscillated on millennial time scales in the Pleistocene North Atlantic, but there are few records of Holocene variability.Expand
Abrupt climate fluctuations in the tropics: the influence of Atlantic Ocean circulation
Several prolonged droughts in the Sahel and tropical Mexico during the past 14,000 years were coincident with large injections of fresh water into the northern North Atlantic Ocean. The link betweenExpand
The Little Ice Age as Recorded in the Stratigraphy of the Tropical Quelccaya Ice Cap
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. Expand
Possible role of dust-induced regional warming in abrupt climate change during the last glacial period
RECORDS from loess, sediments and ice cores indicate that the concentrations of tropospheric aerosols were higher in glacial periods than they are today, and that they peaked just before glacialExpand
A 20,000-year record of ocean circulation and climate change from the Santa Barbara basin
MUCH of the evidence for climate-driven fluctuations in ocean circulation during the past 20,000 years has come from studies of the North Atlantic region1á-6. The extent to which such interactionsExpand
Record of Volcanism Since 7000 B.C. from the GISP2 Greenland Ice Core and Implications for the Volcano-Climate System
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. Expand

Measurements of key chemical and physical parameters made along continuous and selected long sections of polar ice cores provide reliable past snow accumulation rates and other environmental records.Expand
Are the past variations of the stratospheric sulfate burden recorded in central Antarctic snow and ice layers
Thirty-two snow samples, taken from a pit dug at Dome C (central Antarctica) and covering a continuous time period of about 100 years from 1880 ( +- 5 years) up to the present, have been subjected toExpand
