AGU Fall Meeting session CO34: Reconstructing ice-sheet behavior on millennial timescales

Christopher Fogwill

Dear Cryolisters,

We would like to highlight the following cryosphere focussed session to be held at the AGU 2012 Fall meeting:

CO34: Reconstructing ice-sheet behavior on millennial timescales: Integrating high resolution geological data with model simulations

This session focuses on the comparison and integration of high-resolution numerical ice-sheet models and detailed terrestrial and marine geological data sets, to better resolve the geometry, volume and ice dynamical characteristics of the Earth’s ice sheets. Such reconstructions provide critical benchmarks for ice sheet and climate models and reduce uncertainty in predictions of the response of modern ice sheets (and thus sea level) to climate change. An integrated Earth systems approach is critical to achieve this. It is only by combining high-resolution modelling with comprehensive, highly precise empirical paleo-ice sheet constraints that a full understanding of the mechanisms of past change can be determined, and predictions for the future made with greater confidence.

In light of ongoing developments in the fields of high-resolution ice sheet modelling, allied with the increasing precision of geophysical and geochronological tools with which to reconstruct ice sheet change, we invite submissions from groups and individuals addressing data / model comparisons of the Greenland and Antarctic ice sheets and paleo ice sheets during major climate transitions such as those recorded after the Last Glacial Maximum and earlier rapid climate transitions. We also encourage submissions from groups and individuals using theoretical and conceptual modelling studies that explicitly incorporate field data (e.g. conventional terrestrial and marine radiocarbon, multiple cosmogenic nuclides as well as marine geophysical data and glacio isostatic adjustment) 

Confirmed keynote speakers include:

Dr Greg Balco:  Berkeley Geochronology Centre
Prof. Paul Valdes: University of Bristol
Dr Paul Bierman: University of Vermont

AGU Abstract

Reconstructing the pattern, timing & rate of decay of Earth’s contemporary and paleo ice sheets during periods of rapid climate change allows us to assess their sensitivity to environmental forcings beyond our short observational window. An integrated Earth systems approach is critical to achieve this & reduce uncertainty in predictions of the response of modern ice sheets (and thus sea level) to future change. This session focuses on the comparison and integration of high-resolution numerical ice-sheet models & detailed terrestrial and marine geological data sets, to better resolve the geometry, volume & ice dynamical characteristics of the Earth’s ice sheets. 

Look forward to see you at fall AGU meeting.
