Stalagmite evidence for East Asian winter monsoon variability and 18O-depleted surface water in the Japan Sea during the last glacial period

Progress in Earth and Planetary Science, 2021
In the East Asian monsoon area, stalagmites generally record lower and higher oxygen isotope (δ18O) levels during warm humid interglacial and cold dry glacial periods, respectively.

Non-spherical microparticle shape in Antarctica during the last glacial period affects dust volume-related metrics [PDF]

Climate of the Past, 2023
Knowledge of microparticle geometry is essential for accurate calculation of ice core volume-related dust metrics (mass, flux, and particle size distributions) and subsequent paleoclimate interpretations, yet particle shape data remain sparse in ...

West Antarctic ice sheet change since the Last Glacial Period [PDF]

Eos, Transactions American Geophysical Union, 2007
The potential for rapid deglaciation, or collapse, of the 2‐million‐square‐kilometer West Antarctic Ice Sheet (WAIS) in response to climate change is one of the most serious environmental threats facing mankind. The WAIS is a marine ice sheet with large parts of its ice grounded below sea level. Complete collapse would result in a global sea level rise

Desertification and Related Climate Change in the Alashan Plateau since the Last 40 ka of the Last Glacial Period

Atmosphere, 2023
Clues of climate change on the Alashan Plateau since the last glacial period (40 ka) are important for revealing the mechanism of desertification of middle-latitude deserts in the Northern Hemisphere (NH).
