Researchers say a giant glacier in East Antarctica is more vulnerable to climate change than previously thought.
Scientists at NASA’s Jet Propulsion Laboratory and the University of California, Irvine, released their analysis of Denman Glacier.
They found over the last 22 years, the 10-mile-wide glacier has retreated nearly three miles and lost about 268 billion tons of ice during that time.
If fully thawed, it would raise sea levels nearly five feet.
A study co-author says scientists have been more concerned about West Antarctica, where the ice has been melting faster in recent years.
But now they’re also focusing on the vulnerability of East Antarctica.
The study co-author said they now know its potential impact on sea levels is just as significant.
