An important ice in Northeast Greenland is unraveling rapidly in the Atlantic Ocean, say experts, who claimed that the melting of the block ice rise half a meter the sea level.
The glacier, known as Zachariae Isstrom, “entered a phase of rapid melting in 2012,” when he tripled smelting rate.
Now you lose mass at a rate of 5.000 million tons per year, according to a study published in the journal Science.
“The shape and dynamics Zachariae Isstrom has changed dramatically in recent years, “said lead study author Jeremie Mouginot, research assistant in the department of geophysics at the University of California, Irvine (UCI).
The glacier is pouring” large numbers of icebergs into the ocean, that merge will result in raising the sea level in the coming decades, “he added.
The finding was based on 40 years of satellite data from space agencies of USA. UU. (NASA) and European (ESA) and the air traffic control of the shape, size and position of the glacier over time.
The warm ocean water is eroding the ice from below, and increasing the air temperature is melting the above, explains the research.
“The surface of the glacier is melting as a result of decades of continuous increase in air temperature, while the bottom is committed by currents of warm water, “said Eric Rignot, co-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 emissions of greenhouse gases with potentially catastrophic effects for the planet
