It's a combination boost of changes in ocean circulation, land ice dynamic and land subsidence caused by human activity.

这是人类活动引起的海洋环流、陆冰动力和地面沉降变化的综合结果。

Land, ice, water, and vegetation like trees.

土地、冰、水和植被， 如树木。

Most of the Arctic's land ice is locked up in the Greenland ice sheet.

北极的大部分陆地冰被锁在格陵兰冰原中。

Glaciologists, the scientists who study ice and glaciers, know that when icebergs calve, it can make the land ice more likely to collapse.

研究冰和冰川的科学家冰川学家知道，当冰山崩解时， 陆地冰更容易崩塌。

Melting land ice is exposing land that has been buried under ice for centuries to millennia -- but could now become a potential site for mineral exploration.

陆地上的冰川融化后，埋藏在冰下数百年至数千年的土地暴露出来，成为潜在的矿产勘探地点。
