The East Antarctic Ice Sheet has been frozen for at least 14 million years, even though Antarctica is getting warm.

This was found by scientists when they dated back its ancient lake, which has been frozen for 14 million years.

"The Pliocene is sometimes thought to be an analog to what Earth will be like if global warming continues," said Jane K. Willenbring, one of the researchers, in a news release. "This gives us some hope that the East Antarctic Ice Sheet could be stable in today's and future climate conditions."

Researchers believe that the marine portion of the West Antarctic Ice Sheet will vanish, while studies from the past few years show that the sea levels will go up by a few meters with the melting of ice.

However, with the East Antarctic Ice Sheet being bigger by 20 times, its melting could create a cataclysm in this region.

But as the sheet has been frozen for so long, the scientists hope that there may not be such a collapse of the earth as feared.

The findings are published in Scientific Reports.
