It may be hard to believe, but Antarctica was once covered in towering forests.
One hundred million years ago, the Earth was in the grip of an extreme Greenhouse Effect.
The polar ice caps had all but melted; in the south, rainforests inhabited by dinosaurs existed in their place.
These Antarctic ecosystems were adapted to the long months of winter darkness that occur at the poles, and were truly bizarre.
But if global warming continues unabated, could these ancient forests be a taste of things to come?
One of the first people to uncover evidence for a once greener Antarctic was none other than the explorer, Robert Falcon Scott.
Toiling back from the South Pole in 1912, he stumbled over fossil plants on the Beardmore Glacier at 82 degrees south. The extra weight of these specimens may have been a factor in his untimely demise.
Yet his fossil discoveries also opened up a whole new window on Antarctica's sub-tropical past.

Are there signs of inhabitation by humans?
Piri Reis map: In 1929 a map was found in a library in Constantinople, Turkey this map was drawn in 1513 by a Turkish admiral, admiral Piri Reis, the strange thing about this map, is that it shows futures of the earth that nobody in 1513 should have been able to know...

Ice cores drilled from southern Greenland have revealed the first evidence of a surprisingly lush forest that existed in the region within the past million years. The findings from an international study published today in the journal Science suggest that the southern Greenland ice sheet may be much more stable against rising temperatures than previously thought.
Researchers analysed ice cores from a number of locations in Greenland, including Dye 3 in the south of the country. From the base of the 2km deep Dye 3 core, they were able to extract what they believe is likely to be the oldest authenticated DNA obtained to date.
By analysing these DNA samples, the researchers identified a surprising variety of plant and insect life, including species of trees such as alder, spruce, pine and members of the yew family, as well as invertebrates related to beetles, flies, spiders, butterflies and moths. The researchers believe that the samples date back to between 450,000 and 800,000 years ago.

It seems like we are hearing about these types of discoveries almost daily if not hourly now. The Russians have either comer close or actually penetrated the submerged lake. We are finding signs of life under the ice.
Makes one wonder if at some point we will find a pyramid or signs of a lost civilization down there.
At the very least we have a lot of ground to cover with Antartica so it should be in the news for some time to come now.
The Forests..
The Lakes...
Are there signs of inhabitation by humans?
Will we find the secret Nazi base?
Will we find the entrance to the center of the Earth?
Will we unearth pyramids?
Will we find any earth shattering discoveries that landed here from outerspace millions of years ago...
The game is really starting to get intresting sports fans...
