Andean drought and glacial retreat tied to Greenland warming during the last glacial period [PDF]

open access: yesNature Communications, 2020
How the abrupt warming events recorded in Greenland ice cores during the last glacial cycle have influenced the tropical climate is not well known. Here the authors present new lake sediment data from the Peruvian Andes that shows that these events ...

The Glacial Period [PDF]

open access: yesNature, 1874
BOTH Mr. Belt and Mr. Bonney, have, I think, missed the one point on which the question under discussion turns. The shell-bearing drift-gravels are well stratified. I can speak to those in the neighbourhood of Macclesfield, which run up to 1,100 ft. above the sea, being also very delicately, current-laminated. I am puzzled to imagine how this structure

Millennial and orbital scale variability of the South American Monsoon during the penultimate glacial period. [PDF]

open access: yesSci Rep, 2019
The presence of large, rapid climate oscillations is the most prominent feature of the Earth’s last glacial period. These oscillations are observed throughout the Northern Hemisphere and into the Southern Hemisphere tropics.

The Glacial Period [PDF]

open access: yesNature, 1873
PROF. TYNDALL has several times called attention to a point in regard to the height of the snow-line, which seems to be steadily overlooked by those who speculate on the causes of the great prevalence of snow during the glacial epoch. It is of course well known that the height of the snow-line at any place is determined mainly by two things, viz., the ...

Limited grounding-line advance onto the West Antarctic continental shelf in the easternmost Amundsen Sea Embayment during the last glacial period. [PDF]

open access: yesPLoS One, 2017
Precise knowledge about the extent of the West Antarctic Ice Sheet (WAIS) at the Last Glacial Maximum (LGM; c. 26.5–19 cal. ka BP) is important in order to 1) improve paleo-ice sheet reconstructions, 2) provide a robust empirical framework for ...

Timing and causes of North African wet phases during the last glacial period and implications for modern human migration. [PDF]

open access: yesSci Rep, 2016
We present the first speleothem-derived central North Africa rainfall record for the last glacial period. The record reveals three main wet periods at 65-61 ka, 52.5-50.5 ka and 37.5-33 ka that lead obliquity maxima and precession minima.

Hydrographic changes in the Agulhas Recirculation Region during the late Quaternary [PDF]

open access: yesClimate of the Past, 2014
The strength of Southern Hemisphere westerlies, as well as the positions of the subtropical front (STF), Agulhas Current (AC) and Agulhas Return Current (ARC) control the hydrography of the southwestern Indian Ocean. Although equatorward migration of the

Fire history in arid and semi-arid regions of northwest China during the last glacial period inferred from a charcoal record in Hetao Basin. [PDF]

open access: yesPLoS ONE
In arid and semi-arid regions of northwest China, the ecological environment is fragile and fire occurs frequently. Fire has an important impact on the regional ecological environment.
