No. 138: NOV-DEC 2001
A somewhat politically incorrect observation appears in this article.
However, the news that the Antarctic Peninsula's ice shelves may have come and gone at least once since the end of the last ice age, about 11,000 years ago, suggests that people may not be fully to blame for the disappearance now underway.
Supporting foregoing evidence are studies of Antarctic lake sediments and ancient abandoned penguin rookeries. Everything points to a warmer, more humid Antarctica between 2,500 and 4,000 years ago.

Comment. The warmer Antarctic just portrayed might explain those old maps, such as that of Piri Re'is, that seem to depict a relatively ice-free Antartica. The more daring of us might postulate sea commerce between South America, southern Africa, and Australasia during those halcyon days!
