DESCRIPTION:Modeling iceberg drift and decay in modern and glacial climates
 \n\nUnder global warming\, the calving of icebergs into the polar oceans i
 s expected to increase. As a result\, the role that icebergs play in Earth
 's climate system has received a recent surge of interest\, and efforts ar
 e underway to explicitly represent icebergs in GCMs. A better understandin
 g of how icebergs drift and decay will help facilitate an accurate represe
 ntation of icebergs and guide the interpretation of GCM results. In this t
 alk I will present an idealized analytical model that we developed to aid 
 this effort. I will use the model to address (i) which climate model varia
 bles are most important to accurately model iceberg evolution and (ii) whe
 ther climate models do a good job simulating these variables. I then will 
 turn to episodes of massive iceberg discharge\, called Heinrich Events\, w
 hich occurred during the last glacial period. These events are believed to
  have had large-scale impacts on the global climate system. However\, mode
 ling icebergs that lived and melted more than 10\,000 years ago comes with
  its own challenges\, as we will see.
