从极地冰芯中获得的化学和同位素记录提供了地球系统科学中一些最具标志性的数据集。在这里，我讨论了不同的记录是如何在冰盖中形成的，特别强调了雪/冰相化学之间的对比，并被困在气泡中。还可以对通过冰盖上层雪层缓慢扩散的空气进行大量采样，以提供关于大气成分的更近期的历史信息。化学和地球物理的问题，必须解决解释冰芯数据的大气成分和排放量的变化也突出显示。冰芯和雪气提供了关于最近变化（过去几十年到几个世纪）的特别有力的证据，包括关于活跃的温室气体或平流层消耗剂的化合物增加的其他无法获得的数据。在更长的时间尺度上（南极洲长达80万年），冰芯揭示了地球化学循环的重大变化，这是冰期和间冰期之间气候重大变化的反馈。
Chemical and isotopic records obtained from polar ice cores have provided some of the most iconic datasets in Earth system science. Here, I discuss how the different records are formed in the ice sheets, emphasising in particular the contrast between chemistry held in the snow/ice phase, and that which is trapped in air bubbles. Air diffusing slowly through the upper firn layers of the ice sheet can also be sampled in large volumes to give more recent historical information on atmospheric composition. The chemical and geophysical issues that have to be solved to interpret ice core data in terms of atmospheric composition and emission changes are also highlighted. Ice cores and firn air have provided particularly strong evidence about recent changes (last few decades to centuries), including otherwise inaccessible data on increases in compounds that are active as greenhouse gases or as agents of stratospheric depletion. On longer timescales (up to 800,000 years in Antarctica), ice cores reveal major changes in biogeochemical cycling, which acted as feedbacks on the very major changes in climate between glacial and interglacial periods.
