USGS Public Lecture Series: Baked Alaska--What's Happening to the Glaciers in Alaska?
USGS Public Lecture Series: Baked Alaska--What's Happening to the Glaciers in Alaska?Glaciers are Earth's largest reservoir of freshwater. As they change, so does global sea level. Alaska has one of the largest accumulations of glaciers anywhere on Earth outside of the Polar regions. For most of the past half century, Alaska has experienced a significant increase in temperature that has profoundly impacted its glaciers. Join USGS scientist Dr.

Redoubt Volcano Plume
Beginning in early November 2008 Redoubt Volcano, 106 miles southwest of Anchorage, AK, began to show signs of unrest including significant changes in gas emission and heat output. On November 5, 2008, the Alaska Volcano Observatory (AVO) raised Redoubt's Aviation Color Code to Yellow and the Volcano Alert Level to Advisory.
