"A large hole has been detected during the ”domedagsglaciären” Thwaites in the Antarctic. "
"Now, warns a team of researchers led by Nasa of the consequences – the glacier is melting faster than previously calculated. "
"– When the heat and water can penetrate under the glacier melts faster, " says Pietro Milillo, the lead author of the Nasa study. "
"A cavity two thirds the size of Manhattan, with 300 metres in height, have been detected in one of the two big glaciers on Antarctica, the Thwaites glacier. "
"Thwaites is one of two glaciers that scientists believe could threaten large parts of humanity, because the melting is sharp and can raise the water level significantly. "
"– the Size of the cavity in a glacier plays an important role for melting. When the heat and water can penetrate under the glacier melts faster, " says Pietro Milillo, lead author of the study and one of the researchers at the University of California NASA laboratory."
"The two glaciers Thwaites and Pine Island are the so-called marine ice. The ice is connected to the sea and is therefore directly exposed to any change and warmer ocean currents. The glaciers forms a kind of plug that keeps the back and prevents the ice from flowing out from the underlying parts of the antarctic ice-cap, therefore they often are called ”domedagsglaciärerna”. At the same time, the melting faster in Antarctica than in many other places."
"New research at Stockholm university, led by Martin Jakobsson, professor in the maringeologi and geophysics, also show that the process in which marine ice withdraw can go incredibly fast."
"– Just the ice is not so stable, they are in contact with the sea, have complex structures at the bottom and we have too few details about how they look. They are very difficult to predict, but we know that they are affected by continued climate warming, " says Martin Jakobsson. "
"Martin Jakobsson doesn't want to make similar estimates because the Antarctic is so complex. But he notes:"
" The marine ice is exposed. At the climate change and warmer temperature affected the marine ice first. "
