One of the most dramatic climate change events observed in marine and ice core records is the Younger Dryas, a return to near-glacial conditions that punctuated the last deglaciation. High-resolution, continuous glaciochemical records, newly retrieved from central Greenland, record the chemical composition of the arctic atmosphere at this time. This record shows that both the onset and the termination of the Younger Dryas occurred within 10 to 20 years and that massive, frequent, and short-term (decadal or less) changes in atmospheric composition occurred throughout this event. Changes in atmospheric composition are attributable to changes in the size of the polar atmospheric cell and resultant changes in source regions and to the growth and decay of continental biogenic source regions.
海洋和冰芯记录中观察到的最剧烈的气候变化事件之一是新仙女木事件，它标志着末次冰消期的接近冰川条件的恢复。从格陵兰中部新获得的高分辨率、连续的冰川化学记录记录了当时北极大气的化学成分。该记录表明，新仙女木事件的开始和结束都发生在 10 到 20 年内，而且在整个事件中，大气成分发生了大规模、频繁和短期（十年或更短）的变化。大气成分的变化归因于极地大气细胞大小的变化以及源区的变化，以及大陆生物源区的生长和衰减。
