Breaking the ice: Flickr photo of the day

Michael Clemmer

There is a lot of talk about glaciers these days; vanishing, dropping off into the ocean in giant chunks called icebergs. Sometimes they float out into the shipping lanes and sink ships. (See: Iceberg sinks Titanic)

Icebergs and their smaller siblings, “bergy bits” and “growlers,” boom like thunder as they calve away from their parent glacier and when they do, they reveal the remarkable turquoise that lies within. It’s turquoise because the densely packed ice of the glacier squeezed out every other color in the spectrum.

Yes, the glaciers are indeed melting at an alarming rate; Montana’s Glacier National Park may be without its glacier in less than 20 years. Almost 70 percent of all the freshwater on Earth is held in the polar ice caps and glaciers.  That’s something to think about.
