Safety is the state of being "safe" (from French sauf), the condition of being protected from harm or other non-desirable outcomes. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk.
Understanding how glacier sliding and iceberg calving contribute to loss in ice sheet models can improve predictions of global sea-level changes. This is hampered by the inaccessibility of a glacier's base and its calving front.
