Book excerpt: Abstract: The Greenland ice sheet, the planets second largest ice mass, has most recently been in a state of negative mass balance, contributing to about 15% of global sea level rise between 1991 and 2000 (Box et al., 2004). Results from NASA's Airborne Topographic Mapper (ATM) show an increase in the rate of Greenland's ice loss from 50 to 90 km3/yr in the past 11 years (Krabill et al., 2004) corresponding to a global sea level rise of .25 mm/year since 1997. Debate exists as to whether or not this loss is caused by recent increases in temperature, or by dynamic processes.
