Journal ArticleDOI
Contribution of Antarctica to past and future sea-level rise
Robert M. DeConto,David Pollard +1 more
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
Jonathan A. Foley,I. Colin Prentice,Navin Ramankutty,Samuel Levis,David Pollard,Steven Sitch,Alex Haxeltine +6 more
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.
Robert M. DeConto,David Pollard +1 more
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
David Pollard,Atilla Aydin +1 more
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
Paul Segall,David Pollard +1 more
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.
