Summary of Research on Climatic Influences from Volcanic Activities and Depositional Records of Volcanic Matters in Ice Cores

In this paper,the mechanisms of volcanic eruptions impacting climate in different time scales are summarized,the research history of the volcanic records in ice cores from different locations is reviewed,the modeling results of volcanic influences with different models are expounded,and finally the uncertainties in the interrelated researches are pointed out.The main results include the following aspects : volcanic activities can cause the climatic fluctuation through the volcanic matter(aerosols).The activity is significant in the timescale of year to decade.However,it is controversial for centurial and millennial time scale.Volcanic records in the ice cores can provide important information for understanding the climatic effects resulted from the volcanic activities in history.Using the volcanic records from ice cores,the climatic effects from the volcanic activities in different regional scale can be calculated from many models,giving important theoretical support for analyzing the principles of climatic effects from volcanic activities,and providing useful materials for studying the volcanic effects in the future.However,many problems and uncertainties still exist in the modeling results and correlative researches.Further attention is needed to pay in the future.
