Antarctica: Secrets Beneath the Ice Documentary by NOVA

Geschreven op 21-10-2015 - Erik van Erne. Geplaatst in Klimaat Facebooktwitterredditpinterestlinkedintumblrmail

AntarticaAlmost 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.

    Happy Antarctica Day!

    December 1 is Antarctica Day, which celebrates the anniversary of the signing of the Antarctic Treaty in 1959 and the setting aside of nearly 10% of the Earth “forever to be used exclusively for peaceful purposes … in the interests of all mankind.”

    The Treaty recognizes Antarctica as a preserve for peace and scientific study and went into effect with 12 signatories. Today, more than 50 nations recognize the Treaty. It is the foundation upon which decades of scientific achievements and advancements rest.

    Among other provisions, the Treaty froze territorial claims to the continent, banned nuclear weapons and waste on the continent, and preserved the entire region south of 60 degrees south latitude for peaceful purposes. The banning of activities of a military nature makes it effectively the first nuclear-arms control agreement in history.
