The world's mountain glaciers contain just 1% of all the ice on Earth,

but their rapid melting accounts for about a third of recent sea level rise.

Most of these glaciers that start and end on land shrink away through gradual surface melting,

but others, known as

tidewater glaciers, flow out into the sea. And by calving off massive icebergs, these glaciers

can collapse in the blink of an eye, geologically speaking. For example, the Columbia Glacier

in Alaska's Chugatch Mountains is a tidewater glacier that once filled a long fjord. It's retreated 12 miles in just the last 25 years.

So this tiny little glacier in Alaska is capable of producing 1% of the sea level rise budget.

And so we know that individual calving glaciers can do crazy things and can act really dramatically and can have this rapid response.

Shad O'Neill, a glaciologist with the U.S. Geological Survey in Anchorage,

and co-author of a new study in the journal Geophysical Research Letters.

Scientists thought that tidewater glaciers, because of their unstable behavior,

might be an

important source of the torrent of meltwater flowing out of Alaska and northwest Canada, where

ice has been disappearing at especially alarming rates. But all mountain glaciers, tidewater,

and otherwise, are notoriously hard to quantify. So O'Neill and his colleagues undertook the
