Global warming has caused widespread surface lowering of mountain glaciers. By comparing two firn cores collected in 2018 and 2020 from Corbassière glacier in Switzerland, we demonstrate how vulnerable these precious archives of past environmental conditions have become. Within two years, the soluble impurity records were destroyed by melting. The glacier is now irrevocably lost as an archive for reconstructing major atmospheric aerosol components.
全球变暖已导致山地冰川大面积消融。通过对比2018年和2020年从瑞士科尔巴西耶冰川采集的两根雪芯,我们证明了这些记录过去环境状况的珍贵档案变得多么脆弱。在两年内,可溶性杂质记录因融化而被破坏。作为重建主要大气气溶胶成分的档案,这座冰川如今已无可挽回地消失了。
