Pbs Learning Media: Antarctic Ice: Sea Level Change

View this clay animation video by NOVA to examine the reasons sea levels will not uniformly rise around the world. Factors affecting sea levels include climate change, the natural tilt of the ocean, expansion of water, and gravity....

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.

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.

Scientists study ice sheets because they influence weather and climate, playing a role in atmospheric and ocean circulation. Ice sheets can also have huge impacts on global sea levels because they store so much water. Explore this...

A mulit-media lesson where students explore the role that ice plays on Earth, the factors causing it to melt, and the local and global consequences of melting ice.

With the global temperature on the rise, the effects of climate change are starting to be seen. However, many people have a difficult time conceptualizing the long-term effects, such as sea levels rising. Given an easy and effective...

Observe how the sea ice changed in 2016 after it reached its maximum extent in late March and proceeded through the melt season in this video from NASA. Scientists study sea ice because it influences global climate. Resouces include...

The Arctic plays an important role in regulating Earth's climate. The region reflects much of the Sun's energy and helps keep the planet cool. Data collected by NASA have revealed that sea ice in the Arctic has steadily declined over the...

NASA's Scientific Visualization Studio uses data from several sources to track seasonal changes in Arctic sea ice and land cover over time. Scientists study sea ice because it influences global climate. Watch the following visualization...

Scientists study sea ice extent closely because it influences global climate. Follow the decline in Arctic sea ice in this animation adapted from NASA showing the yearly maximum and minimum sea ice extents from 1999 to 2016. Resources...
