TL;DR: The recovery of a deep ice core from Dome C, Antarctica, that provides a climate record for the past 740,000 years is reported, suggesting that without human intervention, a climate similar to the present one would extend well into the future.

TL;DR: The most direct evidence to date that active entrainment occurs at the beds of cold glaciers, without bulk freezing of water, has been provided in this paper, where gas content and isotopic composition of debris-rich basal layers of a polar glacier, Meserve Glacier, Antarctica, which has a basal temperature of −17 °C.

TL;DR: Ice-core data from the Antarctic Vostok core is used to reconstruct a complete atmospheric carbon dioxide record for MIS 11 and indicates that values for carbon dioxide throughout the interglacial period were close to the Earth's pre-industrial levels.

TL;DR: In this paper, the authors investigate the ice, debris and stable isotope characteristics of basal ice exposed at the margin of the Greenland ice sheet and report evidence of two separate zones of debris entrainment beneath the ice sheet.

TL;DR: In this paper, the Tsanfleuron Glacier was analyzed by atomic absorption for Ca, Mg, Na, and K. The results showed that the basal ice is distinctly richer in Ca and Mg but slightly poorer in Na and K than the overlying glacier ice, and the close agreement obtained between predicted and measured Ca contents in basal ice strongly supported the hypothesis that ice layers at the base of the Tselfleuron glacier are formed at least in part by regelation and that the calcite deposits result from the selective solute rejection that accompanies basal ice growth.
