Antarctica / Re: Pine Island Glacier (PIG) Calving and Discussion

I'm mostly a longtime lurker here, but I must say the detailed analysis here is greatly helping my understanding of the dynamic forces at play. It is apparent to me that as the main PIG has retreated, there is therefore less lateral or constraining forces on the adjacent ice sheets. The lack of constraint combined with the difference in flow speed between adjacent ice streams is now causing them to tear each other apart, thereby compounding the whole issue. I'm sure this was obvious to others, but the clarity provided in the recent animations in how these mechanisms are working is fascinating, and somewhat terrifying. Thank you everyone for the good work and intelligent conversation in here.
