The Ronne Ice Shelf survived the last interglacial 罗纳冰架在末次间冰期中幸存 ▲ 作者：Eric W. Wolff, Robert Mulvaney et al. ▲ 链接：https://www.nature.com/articles/s41586-024-08394-w ▲ 摘要：在此，我们使用了来自Skytrain ice Rise的冰芯海盐数据。该冰芯位于西南极冰盖（WAIS）附近，表明在末次间冰期（LIG）的大部分时间里，罗纳冰架仍然存在，并且接近其当前的范围。水同位素数据与WAIS的退缩一致，但似乎与WAIS和大型南极冰架都消失的更剧烈的模式实现不一致。 这一新的限制要求重新评估LIG海平面预算的其他要素。这一结果还削弱了促使模式模拟预测未来海平面上升速度至2300年及以后的最高预测值的观测基础。 ▲ Abstract：Here we use sea salt data from an ice core from Skytrain Ice Rise, adjacent to WAIS, to show that, during most of the LIG, the Ronne Ice Shelf was still in place, and close to its current extent. Water isotope data are consistent with a retreat of WAIS, but seem inconsistent with more dramatic model realizations in which both WAIS and the large Antarctic ice shelves were lost. This new constraint calls for a reappraisal of other elements of the LIG sea-level budget. It also weakens the observational basis that motivated model simulations projecting the highest end of projections for future rates of sea-level rise to 2300 and beyond. |
