2 Estimate of the size of the cryosphere (Fitzharis 1996) Melting Ice Sheets and Sea Level Rise Image Courtesy of the CIA World Factbook

3 Components of the cryosphere and their time scales (Peter Lemke et al. 2007)

4 Mass Balance Analyses of Ice Sheets Greenland, showing rates of surface-elevation change between the late 1990s and 2003, derived by comparing satellite and aircraft laser-altimeter surveys Antarctica, showing rates of surface-elevation change derived from satellite radar- altimeter measurements Bentley et al. 2007

5 Models for Ice Sheet–Climate Interactions Under Anthropogenic Greenhouse Forcings Two-dimensional pattern of changes of sea level (m) due to ocean thermal expansion and changes in the volume of ice sheets for the simulations a 2 x, b 3x, and c 4x Scenarios for atmospheric concentration of CO2 increasing by 1% per year, until 2x, 3x and 4x pre-industrial levels are achieved Net sea level rise is largest in 3 x (+1.1 m) compared to 4 x (+.6 m) and 2 x (+.2 m) Vizcaino et al. 2008
