Now, another piece of news makes headlines.
Glacier in East Antarctica is shrinking fast
There’s a massive glacier that’s up to 80 miles long in East Antarctica, and it seems to be shrinking at a really alarming rate. The record-setting landscape that’s beneath it has the ability to speed up its demise more and more.
The glacier is called the Denman Glacier and it’s been reported that ut has retreated three miles over a 22-year old period and researchers are concerned that this could be just the beginning of a total meltdown that would cause global sea levels to rise by about 1.5 m.
The fate of the glacier is related not only to the climate change but only in its foundation. The western flank of the glacier is placed on top of the recently-identified as the deepest land canyon on Earth.
This is an ice-filled trough that is extending over two miles below the sea level.
Experts from the University of California, Irvine (UCI), and NASA’s Jet Propulsion Laboratory write in a paper published this week in Geophysical Research Letters that the trough and the slope of the bed of this western flank is retreating really fast.
“Because of the shape of the ground beneath Denman’s western side, there is potential for rapid and irreversible retreat, and that means substantial increases in global sea levels in the future,” according to the lead author Virginia Brancato from NASA, who was previously a postdoctoral scholar at UCI.
Forbes writes that the bed under the glacier is something that’s unusual for eastern Antarctica.
“The ice in West Antarctica has been melting faster in recent years, but the sheer size of Denman Glacier means that its potential impact on long-term sea-level rise is just as significant,” according to the co-author of the study Eric Rignot.
