A robotic ocean float that vanished for over two years just resurfaced in Antarctica—and the data it collected is wild. It secretly tracked temps and salinity under the ice, revealing that one glacier is hanging on, but another is on the brink. Scientists say if the melting gets worse, there’s no undoing the damage. Sea levels could rise for centuries! Makes you think twice about those melting ice caps, right? #Science #Antarctica #ClimateChange
