Read our privacy policy Antarctic sea ice has likely shrunk to a record low, US scientists announced on Monday, raising concerns that the climate crisis is increasingly destabilising the frozen continent. “The downward trend in sea ice may be a signal that global warming is finally affecting the floating ice around Antarctica, but it will take several more years to be confident of it. “Lower sea ice extent means that ocean waves will pound the coast of the giant ice sheet, further reducing ice shelves around Antarctica.” The South Pole region has so far escaped the accelerated melting taking place on the ice sheets of Greenland and the Arctic. NSIDC senior research scientist and University of Manitoba professor Julienne Stroeve said: “The sea ice helps to buffer large floating ice shelves and major outlet glaciers such as Pine Island and Thwaites, and if these glaciers begin a more rapid runaway loss of land ice, it could trigger a dramatic increase in sea level rise rates before the end of this century.” Last year was Earth’s fifth or sixth warmest year on record, according to numerous scientific agencies including Nasa and the European space agency.
