Earth System: Ice and Global Warming | PBS LearningMediaScientific evidence strongly suggests that different regions on Earth do not respond equally to increased temperatures. Ice-covered regions appear to be particularly sensitive to even small changes in global temperature. This video segment adapted from NASA's Goddard Space Flight Center details how global warming may already be responsible for a significant reduction in glacial ice, which may in turn have significant consequences for the planet. This video is available in both English and Spanish audio, along with corresponding closed captions.

Climate Change Affects Glacial Water Source | PBS LearningMediaThis ThinkTV segment demonstrates the effect of climate change on the coastal population of Peru. As climate change forces the mountain glaciers which provide fresh water into retreat, the quality of the fresh water supply is negatively effected.

NOVA | Mountain of Ice: If the Ice Melts | PBS LearningMediaThis interactive adapted from NOVA portrays what might happen to world coastlines if entire sections of the Antarctic Ice Sheet were to melt. By comparing present-day coastline positions with those from the peak glacial advance 20,000 years ago, you can begin to appreciate how much water is contained in glaciers, the importance of monitoring their condition, and the impact accelerated global warming could one day have on sea level.

Layers of Ice

This NASA Wavelength resource provides lessons for grades PreK-5 on ice and the formation of glaciers. The focus is on how the layers of ice in glaciers give us clues about climate change.
