As each rising tide lifts the coastal terminus of the southern continent’s Thwaites Glacier a tiny bit off the seafloor, warm salty water squeezes in underneath, satellite measurements reveal. … Thwaites is especially vulnerable because parts of its grounding zone (where it lifts off its bed and floats on the ocean) sit as far as 1 kilometer below sea level, exposing it to the warmest water.
