Hallo, eco-conscious viewers, and welcome to another edition of Planet
Earth: Our Loving Home. Antarctica’s land mass extends for more than
１４-million square kilometers, ninety-eight percent of which is covered
by the Antarctic ice sheet.
The continent accounts for ９０ percent of the world’s ice and ７２ percent of its freshwater reserves.
climate change is rapidly thawing this ice, and if the entire sheet
were to melt, Earth’s sea level would rise ６０ to ７０ meters, an
unimaginable outcome for all beings on the planet.
world’s attention has been drawn to the rapidly collapsing Wilkins Ice
Shelf, a ４,０００-square-kilometer mass of floating ice in the western
part of the Antarctic Peninsula.
A thin, ４０-kilometer ice
bridge, the last piece keeping the Shelf in place, shattered in April
２００９, an event that is expected to cause the Shelf to disintegrate at
an even faster rate.
To learn more about the effects of global
warming on Antarctica, we spoke with Dr. Ted Scambos, lead scientist at
the University of Colorado’s National Snow and Ice Data Center in the
Dr. Scambos’s research covers glaciology, remote sensing,
geochemistry and planetary science. His current studies involve
Antarctica’s ice sheet, ice shelves and sea ice.

Panel on Climate Change report 『Climate Change ２００７: The Physical
