Extreme Ice

Nova has a fantastic new documentary — Extreme Ice — about our disappearing glaciers, and you can catch it online. Time-lapse photography shows glaciers calving and receding at an alarming rate. But it is cool to watch.

Here we are in 1999 at Aialik Glacier, Kenai Fjords National Park, Alaska.

What would be the problem if there were no glaciers? Many people get their drinking water from glacial streams and rivers, not to mention the fisheries and agriculture that are dependent on these waterways. Also, if the glaciers were to disappear, plus the ice sheets of Greenland and Antarctica, it is predicted that the sea level would rise enough to wipe out many coastal communities.

Currently in the news, the bridge of ice to the Wilkins Ice Shelf in Antarctica has collapsed, which could facilitate further breaking up of the ice shelf. See Wikipedia.
