There was a news report about some explorere going there to check on the ice thickness, and it was alot thinner than they thought from satellite pictures. If the trends continue there will be no ice in the north in the next 10 to 20 years max.

Put it in this context. The Earth did not always have ice caps.

Now if there is npo ice in the north then it will cause increased rising in the temperature because there is no reflecting of the sun's light.
The northern coastline of Antarctica is perfectly detailed. The most puzzling however is not so much how Piri Reis managed to draw such an accurate map of the Antarctic region 300 years before it was discovered, but that the map shows the coastline under the ice.
Further and more accurate studies have proven that the last period of ice-free condition in the Antarctic ended about 6000 years ago. There are still doubts about the beginning of this ice-free period, which has been put by different researchers everything between year 13000 and 9000 BC.
The question is: Who mapped the Queen Maud Land of Antarctic 6000 years ago? Which unknown civilization had the technology or the need to do that?
It turns out that finding solutions to global warming may be more than a global environmental priority; it could also be a matter of national security. According to a report by the Military Advisory Board, a group of retired general officers from all branches of the U.S. military, there is a clear link between climate change and terrorism.
Global warming will lead to droughts, more frequent and severe hurricanes and storms, and rising sea levels that are predicted to destabilize many nations and to create as many as 50 million environmental refugees by 2010. People left homeless or plunged into poverty, hunger and disease by rising temperatures and other effects of global warming are likely to be susceptible to extremist ideologies. Amy Zalman, Guide to Terrorism Issues for About.com, has more details.

The Piri Reis map does not show Antarctica, with or without ice. It's pretty much just an inaccurate map due the the lack of means of determining longitude in the 16th century and the fact that there was, in those days, no one who had any idea of how to represent a spherical surface on a flat projection.

The last time Antarctica had no ice (or major glaciation anyway) was about 40 million years ago and this is what it would have looked like;
