ANCHORAGE, Alaska (AP) — The rate of icebergs breaking off from Alaska’s Columbia Glacier will significantly slow within eight years, according to a new study.

Scientists from the University of Colorado at Boulder used a computer model that indicated the tidewater glacier by 2020 will retreat to a new, stable position in shallower water. The glacier, the study said, will achieve “dynamic equilibrium,” where the rate of ice accumulation equals the rate of ice ablation, or ice removal.
