Trying to understand how a tidewater glacier reacts to a warming climate ...
August 2010 landsat image of Columbia Glacier overlaid with the curvilinear coordinate system employed by Meier et al. (1985) to describe the “main” flowline (M) and tributaries “west” (W), “main-west” (MW) and “east” (E). Inset depicts location of Columbia Glacier in Alaska. Photo courtesy of Colgan, et. al.

The
scientists then compared thousands of outputs from the computer model under
different assumptions with the wealth of data that exists for the Columbia
Glacier.
The
batch of outputs that most accurately reproduced the well-documented history of
retreat was run into the future to predict the changes the Columbia Glacier
will most likely experience until the year 2100. The researchers found that
around 2020 the terminus of the glacier will retreat into water that is
sufficiently shallow to provide a stable position through 2100 by slowing the
rate of iceberg production.
