The emergence of low-frequency, high-amplitude, quasi-periodic (∼ 100-kyr) glacial
variability during the middle Pleistocene in the absence of any significant change in orbital …

Interglacials, including the present (Holocene) period, are warm, low land ice extent (high
sea level), end‐members of glacial cycles. Based on a sea level definition, we identify …

On the basis of fossil and archaeological data it has been hypothesized that the exodus of
Homo sapiens out of Africa and into Eurasia between~ 50–120 thousand years ago …

Reconstructions of Earth's past climate strongly influence our understanding of the dynamics
and sensitivity of the climate system. Yet global temperature has been reconstructed for only …

A high-resolution deuterium profile is now available along the entire European Project for
Ice Coring in Antarctica Dome C ice core, extending this climate record back to marine …

Global surface temperature has increased≈ 0.2° C per decade in the past 30 years, similar
to the warming rate predicted in the 1980s in initial global climate model simulations with …

Paleoclimate data show that climate sensitivity is~ 3 deg-C for doubled CO2, including only
fast feedback processes. Equilibrium sensitivity, including slower surface albedo feedbacks …

摘要主要评述了近年来泥河湾盆地磁性地层学的研究进展, 包括建立泥河湾组的磁性地层年代格
架, 厘定泥河湾动物群的时代和确定华北地区早期人类活动年代序列. 研究表明: 第一 …

The dominant period of Pleistocene glacial cycles changed during the mid-Pleistocene from
40,000 years to 100,000 years, for as yet unknown reasons. Here we present a 2.1-million …

Determining the timing and amplitude of tropical sea surface temperature (SST) change is
an important part of solving the puzzle of the Plio-Pleistocene ice ages. Alkenone-based …
