Antarctica used to be host to beech forests, and if we carry on the way we are, the trees will one day return.
3D headed out to the ice to meet the scientists who are unearthing Antarctica's past in order to predict the future.
It covers an area roughly the size of Australia, with ice an astounding four kilometres thick – a monstrous swathe of ice that's home to 70 percent of the world's fresh water.
But the question hanging over the scientific community down there is – how long will it remain like this?
To find out just how this vast reservoir is in jeopardy, 3D has gone to the top of Friis Hills in the Dry Valleys.
Watch the video for the full 3D report.
