Late Glacial Stage and Holocene Tropical Ice Core Records from Huascar�n, Peru
TLDR
Two ice cores from the col of Huascar�n in the north-central Andes of Peru contain a paleoclimatic history extending well into the Wisconsinan (W�rm) Glacial Stage and include evidence of the Younger Dryas cool phase, implying that a strong warming has dominated the last two centuries.
Tropical Climate Instability: The Last Glacial Cycle from a Qinghai-Tibetan Ice Core
An ice core record from the Guliya ice cap on the Qinghai-Tibetan Plateau provides evidence of regional climatic conditions over the last glacial cycle. 36 Cl data suggest that the deepest 20 meters
Annually resolved southern hemisphere volcanic history from two Antarctic ice cores
The continuous sulfate analysis of two Antarctic ice cores, one from the Antarctic Peninsula region and one from West Antarctica, provides an annually resolved proxy history of southern semisphere
UV induced mass‐independent sulfur isotope fractionation in stratospheric volcanic sulfate
Sulfuric acid aerosols produced in the stratosphere following massive volcanic eruptions possess a mass‐independent sulfur isotopic signature, acquired when volcanic SO2 experiences UV
A 4100-year record of explosive volcanism from an East Antarctica ice core
Extensive archives of volcanic history are available from ice cores recovered from the Antarctic and Greenland ice sheets that receive and preserve sulfuric acid fallout from explosive volcanic
Cold decade (AD 1810–1819) caused by Tambora (1815) and another (1809) stratospheric volcanic eruption
Climate records indicate that the decade of AD 1810–1819 including “the year without a summer” (1816) is probably the coldest during the past 500 years or longer, and the cause of the climatic
Volcanoes and climate
Of the natural forcings causing short‐term climatic variations, volcanism, along with its climatic impact, is perhaps the best understood. The primary net result of the impact is the reduced receipt
South Pole ice core record of explosive volcanic eruptions in the first and second millennia A.D. and evidence of a large eruption in the tropics around 535 A.D.
[1] A record of explosive eruptions over the last 1830 years reconstructed from a South Pole, Antarctica, ice core extends the coverage of volcanic history to the start of the first millennium A.D.
Evidence from sulfate mass independent oxygen isotopic compositions of dramatic changes in atmospheric oxidation following massive volcanic eruptions
[1] Oxygen isotopic ratio measurements (δ17O and δ18O) of background and volcanic sulfate preserved in South Pole snow and ice were used to investigate the impact on the oxidation state of the
