Response of the East Antarctic Ice Sheet to past and future climate change
Abstract The East Antarctic Ice Sheet contains the vast majority of Earth's glacier ice (about
52 metres sea-level equivalent), but is often viewed as less vulnerable to global warming …

The sensitivity of the Antarctic ice sheet to a changing climate: Past, present, and future
Abstract The Antarctic Ice Sheet (AIS) is out of equilibrium with the current anthropogenic‐
enhanced climate forcing. Paleoenvironmental records and ice sheet models reveal that the …

Exceeding 1.5 C global warming could trigger multiple climate tipping points
Climate tipping points occur when change in a part of the climate system becomes self-
perpetuating beyond a warming threshold, leading to substantial Earth system impacts …

An ancient river landscape preserved beneath the East Antarctic Ice Sheet
Abstract The East Antarctic Ice Sheet (EAIS) has its origins ca. 34 million years ago. Since
then, the impact of climate change and past fluctuations in the EAIS margin has been …

Abrupt CO2 release to the atmosphere under glacial and early interglacial climate conditions
Pulse-like carbon dioxide release to the atmosphere on centennial time scales has only
been identified for the most recent glacial and deglacial periods and is thought to be absent …
