New sea-level rise projections for Sweden are presented. Compared to earlier projections, we have here, more carefully, taken regional variations in sea-level rise into consideration. The better treatment of regional variations leads to lower sea-level rise projections for Sweden. However, recent research has also shown that Antarctic ice loss, in high emission scenarios, could be greater than what was believed earlier. Taking also this into account, we find a near cancellation between the increased Antarctic contribution and the decrease owing to the better treatment of spatial inhomogeneities. Sweden’s sensitivity to melt from Antarctica and Greenland is also estimated using a new set of sea-level fingerprint kernels, and the sensitivity to melt from Greenland is found to be weak. To illustrate the influence mean sea-level rise has on extreme sea levels, it is also shown how the return period of sea-level extremes changes as a function of time owing to mean sea-level rise in the different projections.

根据新的IPCC特别报告,瑞典的海平面上升预测:气候变化中的海洋和冰冻圈。

介绍了瑞典的新海平面上升预测。与以前的预测相比,我们在这里更加谨慎地考虑了海平面上升的区域差异。更好地处理区域差异会导致瑞典降低海平面上升的预测。但是,最近的研究还表明,在高排放情景下,南极冰的损失可能比早先认为的要大。还考虑到这一点,由于对空间不​​均匀性的更好处理,我们发现南极贡献增加和减少之间几乎抵消。瑞典对南极洲和格陵兰岛融化的敏感性也使用一组新的海平面指纹核估计,发现格陵兰岛融化的敏感性较弱。
