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

Nature 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 ...

A deep Tasman outflow of Pacific waters during the last glacial period [PDF]

Nature Communications, 2022
Using cold-water corals, this work identifies a deep outflow of Pacific waters via the Tasman Sea during the last ice age, thus highlighting the role of this area for the interoceanic exchange of water masses on climatic time scales.

The spatiotemporal extent of the Green Sahara during the last glacial period [PDF]

iScience, 2023
Summary: The Sahara Desert, one of today’s most inhospitable environments, has known periods of enhanced precipitation that supported pre-historic humans.

Neotropical forest expansion during the last glacial period challenges refuge hypothesis. [PDF]

Proc Natl Acad Sci U S A, 2016
Significance The tropical forests of South America are among the most diverse and unique habitats in the world in terms of plant and animal species. One of the most popular explanations for this diversity and endemism is the idea that forests retracted and fragmented during glacial periods, forming ecological refuges, surrounded by dry lands ...

Equatorial Pacific seawater pCO₂ variability since the last glacial period. [PDF]

Sci Rep, 2019
AbstractThe ocean may have played a central role in the atmospheric pCO2 rise during the last deglaciation. However, evidence on where carbon was exchanged between the ocean and the atmosphere in this period is still lacking, hampering our understanding of global carbon cycle on glacial–interglacial timescales.

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

Climate 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

Consequences of the Last Glacial Period on the Genetic Diversity of Southeast Asians. [PDF]

Genes (Basel), 2022
The last glacial period (LGP) promoted a loss of genetic diversity in Paleolithic populations of modern humans from diverse regions of the world by range contractions and habitat fragmentation. However, this period also provided some currently submersed lands, such as the Sunda shelf in Southeast Asia (SEA), that could have favored the expansion of our

Mechanisms for millennial-scale global synchronization during the last glacial period [PDF]

Paleoceanography, 2005
Global climate during the last glacial period was punctuated by abrupt warmings and occasional pulses of freshwater into the North Atlantic that disrupted deepwater production. These massive freshwater pulses known as Heinrich events arose, in part, from

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

Sci 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.

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]

PLoS 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.
