TL;DR: In this article, a comparison of climate model simulations available from the PMIP1, PMIP2 and CMIP-AR4 intercomparison projects for past and future climate change simulations are examined in terms of polar temperature changes in comparison to global temperature changes and with respect to pre-industrial reference simulations.

TL;DR: A block-structured finite volume method with adaptive mesh refinement (AMR) for three dimensional ice sheets, which allows to discretize a narrow region around the grounding line at high resolution and the remainder of the ice sheet at low resolution.

TL;DR: In this article, a large-scale modeling study of iceberg trajectories and melt rates in the Southern Ocean is presented, where an iceberg model was seeded with climatological iceberg calving rates based on a calculation of the net surface accumulation from each snow catchment area on the Antarctic continent, and the modeled geographic distribution of iceberg meltwater joining the ocean has been calculated and is found in many near-coastal regions to be comparable in magnitude to the excess of precipitation over evaporation.

TL;DR: In this paper, the authors present results of an intercomparison exercise for marine ice-sheet models, using simplified geometrical configura- tions (no lateral variations, no effects of lateral buttressing).

TL;DR: It is suggested that thinning associated with ocean-driven increased basal melt can trigger increased iceberg calving, implying that iceberg calve may play an overlooked role in the demise of shrinking ice shelves, and is more sensitive to ocean forcing than expected from steady state calving estimates.
