Antarctic Ice Movement: Part 2

In this video segment, a team of scientists seeks evidence to support their hypothesis that atmospheric warming -- either now or in the past -- may explain why water has formed beneath the West Antarctic ice sheet, causing ice streams that flow much more quickly than the rest of the ice sheet. This phenomenon has important implications for potential sea level rise.

Segment adapted from NOVA Warnings from the Ice. Might be useful to use this clip with other segments from that program.

Video could be easily implemented in discussion about climate warming and its affects on sea level rise or on glacial melt and how scientists measure change over time.

Suggestions of how to engage students: while watching video clip - note three hypothesis that scientists came up with to explain the described phenomenon.
