متن کاملLittle Ice Age cold interval in West Antarctica: Evidence from borehole temperature at the West Antarctic Ice Sheet (WAIS) Divide
[1] The largest climate anomaly of the last 1000 years in the Northern Hemisphere was the Little Ice Age (LIA) from 1400–1850 C.E., but little is known about the signature of this event in the Southern Hemisphere, especially in Antarctica. We present temperature data from a 300 m borehole at the West Antarctic Ice Sheet (WAIS) Divide. Results show that WAIS Divide was colder than the last 1000-...
متن کاملMedieval Warm Period, Little Ice Age and 20th century temperature variability from Chesapeake Bay
We present paleoclimate evidence for rapid ( < 100 years) shifts of f 2–4 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. These include large temperature excursions during the Little Ice Age (f1400–1900 AD) and the Medieval Warm Period (f800–1300 AD) possibly related to change...
متن کاملSpatial and Temporal Characteristics of the Little Ice Age: The Antarctic Ice Core Record
Recently, ice core records from both hemispheres, in conjunction with other proxy records (e.g., tree rings, speleothems and corals), have shown that the Little Ice Age (LIA) was spatially extensive, extending to the Antarctic. This paper examines the temporal and spatial characteristics of the dust and 5180 infonnation from Antarctic ice cores. Substantial differences exist in the records. For...
متن کاملLittle Ice Age (neoglacial) Paleoenvironmental Conditions at Siple Station, Antarctica
The 550-year records of 6180 and dust concentrations from Siple Station, Antarctica suggest warmer and less dusty atmospheric conditions from 1600 to 1830 A.D. which encompasses much of the northern hemisphere Little Ice Age (LIA).· Dust and 6180 data from South Pole Station indicate that the opposite conditions (e.g. cooler and more dusty) were prevalent there during the LIA. Meteorological da...
