自1996年以来,南极洲丧失的冰量相当于大洛杉矶的10倍,西南极洲和东南极洲的主要冰川退缩是由温暖的海洋水驱动的。
Antarctica lost ice equivalent to 10 times Greater Los Angeles since 1996, with major glacier retreat in West and East Antarctica driven by warm ocean water.
一项为期30年的卫星研究显示,南极洲自1996年以来丧失了相当于大洛杉矶10倍的冰。 其23%的海岸线 — — 特别是在西南极洲的Amundsen和Getz区以及南极洲东部部分地区 — — 正在探索快速地基撤退。
A 30-year satellite study reveals Antarctica has lost ice equivalent to 10 times Greater Los Angeles since 1996, with 23% of its coastline—especially in West Antarctica’s Amundsen and Getz sectors and parts of East Antarctica—experiencing rapid grounding line retreat.
松树岛、斯威兹和史密斯等冰川的冰川撤退了42公里,主要靠冰架下面的温暖海水驱动。
Glaciers like Pine Island, Thwaites, and Smith retreated up to 42 kilometers, driven primarily by warm ocean water undercutting ice shelves.
虽然77%的海岸保持稳定,但调查结果为改进海平面升高预测提供了重要基准,并突显了尽管南极半岛发生了一些无法解释的变化,但区域内不断变数的冰损。
While 77% of the coast remained stable, the findings provide a critical benchmark for improving sea level rise projections and highlight ongoing, regionally variable ice loss despite some unexplained changes in the Antarctic Peninsula.
