This is an animated interactive simulation that illustrates differential solar heating on a surface in full sunlight versus in the shade.

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.

Video presents a broad overview of what (NASA) satellites can tell us about how climate change is affecting oceans.
