过去一万年里冰川的进退说明了气候动态的复杂性。高山冰川留下了壮观的气候变化记录。湖泊、冰碛和其他由过去冰川前进和后退形成的地貌占据了几乎所有山地景观的前景。这些冰川沉积物是过去气候的丰富记录，分布广泛、明显且易于获取。在许多没有沉积物或冰芯记录的地区，它们是仪器记录开始之前唯一的气候记录。 Schaefer 等人在本期第 622 页上的报告。强调了这些冰川记录在了解过去气候动态方面的价值，同时也揭示了其复杂性 (1)。
Glacier advances and retreats over the past 10,000 years illustrate the complexity of climate dynamics. Alpine glaciers leave spectacular records of climate change. Lakes, moraines, and other landforms shaped by past glacier advances and retreats dominate the foreground of nearly all mountain landscapes. These glacial deposits are rich records of past climate that are widespread, obvious, and easily accessible. In many regions without sedimentary or ice-core records, they are the only record of climate before instrumental records began. A report on page 622 of this issue by Schaefer et al. highlights the value of these glacial records in understanding past climate dynamics while also revealing their complexity (1).
