Almost
three miles of ice buries most of Antarctica, cloaking a continent half
again as large as the United States. But when an Antarctic ice shelf
the size of Manhattan collapsed in less than a month in 2002, it shocked
scientists and raised the alarming possibility that Antarctica may be
headed for a meltdown. Even a 10 percent loss of Antarctica's ice would
cause catastrophic flooding of coastal cities unlike any seen before in
human history. What are the chances of a widespread melt? "Secrets
Beneath the Ice" explores whether Antarctica's climate past can offer
clues to what may happen. NOVA follows a state-of-the-art expedition
that is drilling three-quarters of a mile into the Antarctic seafloor.
The drill is recovering rock cores that reveal intimate details of
climate and fauna from a time in the distant past when the Earth was
just a few degrees warmer than it is today. As researchers grapple with
the harshest conditions on the planet, they discover astonishing new
clues about Antarctica's past—clues that carry ominous implications for
coastal cities around the globe.
