Modeling the evolution of Antarctic ice sheet over the last 420,000 years: Implications for altitude changes in the Vostok region
TL;DR: In this article, a thermomechanical three-dimensional model designed to simulate the evolution of the Antarctic ice sheet over long time periods is presented, which incorporates the various types of ice flow found in Antarctica: relatively slow inland ice flow that is essentially due to ice deformation, fast ice flow in the regions with ice streams, and ice shelf flow.

TL;DR: In this paper, the authors present results from ice flow model simulations from 13 international groups focusing on the evolution of the Antarctic ice sheet during the period 2015-2100 as part of the Ice Sheet Model Comparison for CMIP6 (ISMIP6).

TL;DR: In this article, the authors estimate probability distributions for these projections under the new scenarios using statistical emulation of the ice sheet and glacier models, and find that limiting global warming to 1.5 degrees Celsius would halve the land ice contribution to twenty-first-century sea level rise, relative to current emissions pledges.

TL;DR: In this article, the authors used a large ensemble of Greenland ice sheet models forced by output from a representative subset of the Coupled Model Intercomparison Project (CMIP5) global climate models to project ice sheet changes and sea-level rise contributions over the 21st century.

Heinrich event 1: an example of dynamical ice-sheet reaction to oceanic changes
Jorge Alvarez-Solas,Jorge Alvarez-Solas,Marisa Montoya,Marisa Montoya,Catherine Ritz,Gilles Ramstein,Sylvie Charbit,Christophe Dumas,Kerim H. Nisancioglu,Trond Dokken,A. Ganopolski +10 more
TL;DR: In this article, the authors proposed an alternative driving mechanism for Heinrich event 1 (H1; 18 to 15 ka BP), by which North Atlantic ocean circulation changes are found to have strong impacts on Laurentide ice-sheet (LIS) dynamics.
