SUMMIT COUNTY — Alaska’s Columbia Glacier — a poster child for the impacts of global warming — is likely to stop receding around 2020, when the terminus of the glacier retreats into water shallow enough to provide a stable position through 2100 by slowing the rate of iceberg production.
The Columbia Glacier is a large (425 square miles), multi-branched glacier in south-central Alaska that flows mostly south out of the Chugach Mountains to its tidewater terminus in Prince William Sound.
The new study by Boulder-based University of Colorado scientists with the Cooperative Institute for Research in Environmental Sciences shows that a single glacier’s contribution to sea level rise can “turn on” and “turn off” quite rapidly, over a couple of years, with the precise timing of the life cycle being difficult to forecast.
