地球仪周围的北极群岛是地球上除格陵兰和南极冰盖外最强烈的冰川景观之一。在过去几十年中,北极高纬度地区陆地冰的大量损失对全球海平面上升起到了重大作用。在这些地区中,斯瓦尔巴群岛的质量损失最小。然而,这种情况可能会在未来几十年内发生变化,因为斯瓦尔巴群岛预计将在21世纪遭受强烈的气候变暖。在这里,我们提出了广泛的Monte Carlo模拟未来的29个单独的陆地终止冰川的斯瓦尔巴群岛的RCP8.5气候强迫下的冰质量的演变。将29个样本冰川外推到群岛的所有陆地终止冰川,表明该地区到2100年几乎完全消失。在RCP 8.5下,98%的陆地终止冰川将减少到其初始大小的十分之一以下,导致7392±2481平方公里的冰覆盖面积损失。
The high Arctic archipelagos around the globe are among the most strongly glacierized landscapes on Earth apart from the Greenland and Antarctic ice sheets. Over the past decades, the mass losses from land ice in the high Arctic regions have contributed substantially to global sea level rise. Among these regions, the archipelago of Svalbard showed the smallest mass losses. However, this could change in the coming decades, as Svalbard is expected to be exposed to strong climate warming over the 21st century. Here we present extensive Monte Carlo simulations of the future ice-mass evolution of 29 individual land-terminating glaciers on the Svalbard archipelago under an RCP 8.5 climate forcing. An extrapolation of the 29 sample glaciers to all land-terminating glaciers of the archipelago suggests an almost complete deglaciation of the region by 2100. Under RCP 8.5, 98% of the land-terminating glaciers will have declined to less than one tenth of their initial size, resulting in a loss of 7392±2481 km 2 of ice coverage.
