This video segment [3:33] adapted from NOVA explains why ice sheets move. To find out how fast they move, scientists carve a tunnel through a glacier.

Within Antarctic ice sheets are fast-moving streams of ice. This video segment [5:15] adapted from NOVA hypothesizes about how ice streams are the result of warming at the end of the last ice age.

What would happen if a portion of the Antarctic Ice Sheet were to melt? This video segment [3:19] adapted from NOVA uses animations to show the effect of a 6-meter sea-level rise on coastal cities across the world.

PBS site provides links to understanding how glacier movement can reveal the effects of global warming. Contains links to view satellite images of glaciers from space, a video clip and slide show about a science expedition to a glacier...

What happens when the ground under your feet is ice and it's moving? This video segment adapted from NOVA features some of the dangers faced by scientists conducting research in Antarctica.

PBS offers a rare opportunity to explore the glaciers on France's Mt. Blanc in this engaging interactive site. Fun activities for students include following the process a snowflake takes to become a glacier.

Why is the study of glaciers important? Glacial ice serves many functions that affect the entire Earth system, including regulating global moisture, temperature, and ocean salinity. Studying glaciers allow us to better understand how...

A new documentary explores how climate change is affecting the world's glaciers.

In this video, Paul Andersen explains how plate tectonics explains the large-scale system interactions on our planet. Large plates float on the mantle and interact to form the major landforms on the planet. Evidence for plate tectonics...

Glaciers in a remote part of Antarctica appear to be speeding up their slide towards the sea. We'll talk with a researcher trying to figure out why.
