The Melting Is in the Details Global sea level rises and falls as ice sheets glaciers melt grow, providing an integrated picture of changes volume but little information about how much individual fields are contributing to those variations. Knowing regional structure variability during glaciations deglaciations will clarify mechanisms glacial cycle. Clark et al. (p. 710 ) compiled analyzed more than 5000 radiocarbon cosmogenic surface exposure ages order develop a record maximum extent around time Last Glacial Maximum. responses Northern Southern Hemispheres differed significantly, which reveals evolution specific affected provides insight into insolation controlled deglaciation.
