"Glacial isostatic adjustment, relative sea level history and mantle viscosity: reconciling relative sea level model predictions for the U.S. East coast with geological constraints" explores the ability of models to correctly simulate the process of glacial isostatic adjustment (GIA) - the rebound of land masses which were previously compressed under large ice sheets.
Using relative sea level histories, the authors show that a new mantle viscosity model (VM6) improves upon previous versions in simulating this process. Understanding GIA as it occurred in the past is crucial to understanding how the present-day retreat of existing glaciers and ice sheets at the poles will affect global and regional sea level.

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2011, the United States experienced a record high number (14) of climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 670 lives, caused more than 6,000 injuries, and cost $55 billion in damages. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
