It’s the world’s most vulnerable glacier and key to the stability of the West Antarctic Ice Sheet, yet we’re only now getting to know Thwaites Glacier. What took us so long?
Where thick ice sheets in Antarctica meet the ground, small changes could have big consequences
Scientists studying the physics and thermodynamics of Antarctica’s ice sheets say they’ve discovered a potential new weak spot that could accelerate melting and sea level rise over the next several hundred years.
