Contribution of Antarctica to past and future sea-level rise

TL;DR: A model coupling ice sheet and climate dynamics—including previously underappreciated processes linking atmospheric warming with hydrofracturing of buttressing ice shelves and structural collapse of marine-terminating ice cliffs—is calibrated against Pliocene and Last Interglacial sea-level estimates and applied to future greenhouse gas emission scenarios.
Journal ArticleDOI

An integrated biosphere model of land surface processes, terrestrial carbon balance, and vegetation dynamics

TL;DR: The Integrated Biosphere Simulator (IBIS) as mentioned in this paper is a terrestrial biosphere model that integrates a wide range of biophysical, physiological, and ecological processes in a single, physically consistent modeling framework.
Journal ArticleDOI

Rapid Cenozoic glaciation of Antarctica induced by declining atmospheric CO2.

TL;DR: In this simulation, declining Cenozoic CO2 first leads to the formation of small, highly dynamic ice caps on high Antarctic plateaux, and at a later time, a CO2 threshold is crossed, initiating ice-sheet height/mass-balance feedbacks that cause the ice caps to expand rapidly with large orbital variations, eventually coalescing into a continental-scale East Antarctic Ice Sheet.
Journal ArticleDOI

Progress in understanding jointing over the past century

TL;DR: Theoretical methods have been developed to study the evolution of joint sets and the mechanical response of a jointed rock mass to tectonic loading in the Earth's crust as mentioned in this paper.
Journal ArticleDOI

Mechanics of discontinuous faults

TL;DR: In this paper, the authors derived a two-dimensional solution for any number of nonintersecting cracks arbitrarily located in a homogeneous elastic material, including the elastic interaction between cracks.
