摘要
系统地总结了冰芯在揭示过去气候环境变化、太阳活动、温室气体、火山活动、人类活动等方面研究所取得的成就 ,着重对一些有争议的重大问题 (如YoungerDryas事件、温室气体与气候变化之间的关系、南北半球气候变化之间的关系等 )进行了论述 ,并对其中个别问题提出了可能的解决途径 .指出冰芯微生物。
In this paper, the successful achievements of ice core study are comprehensively reviewed in such aspects as past environmental and climatic changes, abrupt climate changes, solar activity, atmospheric dust content, greenhouse gases, volcanism, biogeochemical cycle, universal events and human influences on environment. Some important issues are discussed, such as the Younger Dryas events, the correlation between climate changes and greenhouse gases, and the phase difference between climate changes in the northern and southern hemispheres. Some new research directions in ice core study are suggested too, for examples, microorganism and environmental geomagnetism.
