The widely accepted" Milankovitch theory" explains insolation-induced waxing and waning
of the ice sheets and their effect on the global climate on orbital timescales. In the past half …

Stalagmite is one kind of secondary carbonates formed in limestone caves (speleothem).
After cave water droplets containing Ca 2+ and HCO _3^-HCO 3− drip onto floor, carbonate …

Oxygen isotope records from Chinese caves characterize changes in both the Asian
monsoon and global climate. Here, using our new speleothem data, we extend the Chinese …

摘要石笋是洞穴次生碳酸盐的一种, 是由含Ca 2+ 和HCO3 的洞穴滴水滴到洞穴地面后,
水中碳酸钙在一定条件下过饱和析出, 经年复一年沉积形成. 石笋是古气候研究的重要地质材料 …

Two fundamental questions about the ice-age climate system await satisfactory resolution.
First, if summer solar radiation intensity truly controls the orbital signature of the last glacial …

Cosmogenic nuclide techniques have advanced the geosciences by providing tools for
exposure age dating, burial dating, quantification of denudation rates and more. Advances …

Previous studies have suggested that during the late Pleistocene ice ages, surface-deep
exchange was somehow weakened in the Southern Ocean's Antarctic Zone, which reduced …

This paper reviews current understanding of deglaciation in North, Central and South
America from the Last Glacial Maximum to the beginning of the Holocene. Together with …

Millennial-scale climate oscillations of the last ice age registered in Greenland and Antarctic
ice cores did not always vary in unison. A striking example is that the strongest Antarctic …

Ice‐contact proglacial lakes are generally absent from numerical model simulations of
glacier evolution, and their effects on ice dynamics and on rates of deglaciation remain …
