Extreme Environments: Ice (2008)
The bulk of the earth’s fresh water is locked away in polar ice caps, and 90 percent of the world’s ice can be found in Antarctica. But change is happening at the poles, and at an alarming rate. Ice-dwelling animals, such as the polar bear, are being affected by dwindling ice supplies around the planet. Glaciologists and research teams are working to better understand the effect carbon dioxide emissions are having on the planet’s decreasing ice supplies.
