Ice caps are large expanses of glacial ice and have a slightly domed shape. Partitioning mass loss into these two components is important to understand how the ice sheet responds to a climate forcing, for example in the early 2000s, a number of outlet glaciers in south east Greenland accelerated and retreated, leading to a large mass loss by dynamic processes. For example, recent (beginning in the late 1990s) mass loss via outlet glaciers has been attributed primarily to changing ice‐ocean interactions, driven by both oceanic and atmospheric warming, but the exact mechanisms controlling the onset of glacier retreat and the processes that regulate the amount of retreat … At the maximum of the last ice … A cooler climate in the 1940s allowed some glaciers to briefly advance, but since the 1990s, the pattern has been steady retreat. Unique temperature control system. The steeper glaciers have undergone several advance/retreat cycles during the observation period (1894 to present), while the low-angled glacier showed little terminus response until retreat resulting from the accelerating growth of a proglacial lake commenced in 1983.
