GLACIERS: The Most Important Environmental Impact of the Century (2 Programs on 1 DVD) MULTIPLE SITE USE
Two 20-minute programs describe the most important environmental impact of the century!
THE LIFE OF A GLACIER
Glaciers are one of the main driving forces affecting Earth’s climate and landscape. From Alpine, or Mountain, glaciers, to Tidewater glaciers and icebergs, these massive sheets of ice are constantly moving and changing, almost like a living being. Warming temperatures are causing most glaciers to recede, leaving a changed landscape in their wake. Located in some of the most inhospitable areas of the planet, scientists are venturing to glaciers to study them, looking for clues to climate changes from the past and in the present.
THE DEATH OF A GLACIER
One of the most influential environmental impacts of this century, the decreasing mass of our glaciers has scientists concerned. This program explores glaciers in the Alaskan and Western Canadian regions that are gradually shrinking. Due to numerous environmental factors, glaciers that were once abundant in the Northern regions are now half of their original size. With the human "carbon footprint" growing day by day, Global Warming has become a very real and dangerous impact that our planet, including our glaciers, has to deal with.
