A gigantic hollow hidden under an Antarctic glacier threatens to increase the sea level.
NASA reveals that the Thwaites hides a huge hole that grows at an explosive rate and is part of a vicious circle that accelerates its thaw.
Researchers at NASA's Jet Propulsion Laboratory (JPL) have discovered a gigantic cavity beneath the Thwaites glacier in Antarctica that formed as a result of the melting in the last three years. American space agency.
Although the presence of hollow spaces between the ice and the rocky base was expected by the contact with oceanic waters, the experts were surprised by the dimensions and the "explosive rhythm of growth" of that great hole, which is about 300 meters of height and a volume equivalent to 14,000 million tons of ice.
Chain reaction.
"For years we suspected that the Thwaites were not firmly attached to its rocky base," said Eric Rignot, a researcher at the University of California and NASA. To confirm this hypothesis, this man and his companions used new radars capable of penetrating the thick layer of ice.
