The glacier, known as Zachariae Isstrom, “entered a phase of rapid melting in 2012,” when the rate of smelting tripled.
Now loses mass to a rate of 5 billion tons per year, according to the study published in the journal Science.
“The shape and dynamics Zachariae Isstrom has changed dramatically in recent years,” said lead author study, Jeremie Mouginot, research assistant of the Department of Geophysics of the University of California, Irvine (UCI).
The glacier is pouring “huge amounts of icebergs into the ocean, that merge will result in raising the level Sea in the coming decades, “he added.
The finding was based on 40 years of satellite data from space agencies, as well as air control the shape, size and position of the glacier along the time.
The warm ocean water is eroding the glacier from below, and rising air temperatures are melting the above.
“The surface of the glacier is melting as a result of decades of continuous increase in air temperature, while the bottom is compromised by warm streams of water, “said Eric Rignot, lead author of the study and professor of geophysics at the ICU.
This study is reported two weeks of the international climate conference in Paris (cop21), where an agreement will seek to limit gas emissions with potentially catastrophic greenhouse for the planet.
