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 …

Deconstructing the Last Glacial termination: the role of millennial and orbital-scale forcings
Using an Earth system model of intermediate complexity forced by continuously varying
boundary conditions and a hypothetical profile of freshwater forcing, the model simulates …

Global environmental consequences of twenty-first-century ice-sheet melt
Government policies currently commit us to surface warming of three to four degrees Celsius
above pre-industrial levels by 2100, which will lead to enhanced ice-sheet melt. Ice-sheet …

Freshening by glacial meltwater enhances melting of ice shelves and reduces formation of Antarctic Bottom Water
Strong heat loss and brine release during sea ice formation in coastal polynyas act to cool
and salinify waters on the Antarctic continental shelf. Polynya activity thus both limits the …

Millennial-scale variability in Antarctic ice-sheet discharge during the last deglaciation
Our understanding of the deglacial evolution of the Antarctic Ice Sheet (AIS) following the
Last Glacial Maximum (26,000–19,000 years ago) is based largely on a few well-dated but …

Heat transport across the Antarctic Slope Front controlled by cross-slope salinity gradients
The Antarctic Slope Front (ASF) is a strong gradient in water mass properties close to the
Antarctic margins, separating warm water from the Antarctic ice sheet. Heat transport across …

Antarctic contribution to meltwater pulse 1A from reduced Southern Ocean overturning
During the last glacial termination, the upwelling strength of the southern polar limb of the
Atlantic Meridional Overturning Circulation varied, changing the ventilation and stratification …

Thermal responses to Antarctic ice shelf melt in an eddy-rich global ocean–sea ice model
The response of near-Antarctic waters to freshening by increased glacial melt is investigated
using a high-resolution (0.1°) global ocean–sea ice model with realistic Antarctic water …

Antarctic sea-ice expansion and Southern Ocean cooling linked to tropical variability
A variety of hypotheses, involving sub-ice-shelf melting, stratospheric ozone depletion and
tropical teleconnections, have been proposed to explain the observed Antarctic sea-ice …

Future climate response to Antarctic Ice Sheet melt caused by anthropogenic warming
Meltwater and ice discharge from a retreating Antarctic Ice Sheet could have important
impacts on future global climate. Here, we report on multi-century (present–2250) climate …
