摘要
近几十年来,由于全球变暖所引起的温室气候变化越来越引起人们的关注。科学研究显示,大气中不断上升的CO2浓度是导致气候变暖的主要因素,因而认识和揭示大气CO2浓度与气候变化之间的关系已成为当今科学界研究的热点之一。研究表明,地质历史时期也存在类似的温室气候与全球变暖现象。古生物学家通过对植物化石叶片的研究,成功地获取了地质历史时期古大气CO2浓度变化的信息,因而这一方法日益受到科学界的重视,被认为是从地质记录中获取古大气CO2浓度的最有效途径之一。
For several decades, the greenhouse climate change caused by the global warming effect has attained much more atten- tion to scientific society. Studies revealed that the increasing of CO2 concentration is the main factor of global warming. Therefore un- derstanding of the relationship between CO2 concentration and cli- mate change has became one of the attractive focuses of scientific research. Recent studies show that the similar greenhouse climate and global warming phenomenon were also present during the geo- logical history. Palaeontologists successfully obtained the essential information of palaeo-CO2 change from fossil plant leaves. This method has been recognized as one of the most effective approaches for tracking paleo-CO2 information from geological record.
