西南极冰架的不稳定部分一旦融化，会让海平面上升10英尺。
There is 10 feet of sea level rise stored up in the unstable part of the West Antarctic ice sheet.
但较高的海洋温度会造成冰山和冰架融化，这引起了海平面上升。
But higher ocean temperatures cause icebergs and ice shelves to melt, which raises sea level.

如果冰流加速，冰的流失加速，南极冰架的质量将会减轻，从而重力会变小。
If ice streams speed up and drain the ice faster, ice mass will be lost from Antarctica, and gravity will go down a fraction.
冰盖表面，成行的融雪坑形成许多天然的冰裂缝，并导致各条缝隙连贯起来，横贯整个冰架。
On the surface of the shelf, rows of melt ponds settled into natural crevasses, driving the cracks all the way through the ice shelf.
