Northern science: Alaska glaciers help drive rise in sea level

Geophysical Institute researcher Regina Hock and her colleague Valentina Radic have calculated that the rate of sea-level rise due to the meltwater from glaciers in Alaska and elsewhere will increase by as much as 60 percent by the year 2100. Half of the world’s smallest glaciers may not survive that long.
