"Antarctica's Melting Ice Demands Urgent Attention"
Two new studies shed light on the mysterious realm beneath Antarctica's ice shelves. Using underwater robotics and ground-penetrating radar, scientists have discovered that the melting of the ice shelves is driven by warm ocean water eating away at their undersides. The melting and freezing of seawater within deep crevasses create currents that accelerate the melting process. Additionally, researchers have found that geothermal heat and friction from ice grinding against the ground create rivers of freshwater flowing from the interior of the ice sheets, enhancing melting at the grounding line. These findings highlight the urgent need to reduce carbon emissions to prevent further collapse of Antarctica's glaciers and mitigate the potential rise in sea levels.
