The same uncertainty applies to other possible forcing factors on monsoon variability. In order to answer these questions we need to investigate periods of increased volcanic activity and increased snow cover over the Tibetan Plateau, which all require longer climatic time-series than are presently available. Long paleoclimatic time series will also allow for a more detailed study of putative links between solar variability and the monsoon. To determine the climatic and anthropogenic impacts on key natural resources of water, forests, and air. Global climate is thought to be increasingly under the influence of greenhouse gases and sulfate aerosols as a result of anthropogenic emissions.
Instrumental records extend back only to the beginning of the industrial period.
Therefore, we need to use high resolution paleoclimatic records to extend our understanding of monsoon climate variability back into the pre- industrial period. In so doing, it will be possible to determine if any change in the variability of the Asian monsoon has occurred during the 20th century with respect to recent global environmental changes. To develop predictive models of Asian monsoon variability through an improved understanding of the monsoon climate system. Predicting the monsoon would have great socio-economic importance. By understanding the past monsoon variability and its relationship to various forcing factors, it should be possible to improve our fundamental understanding of this dynamic system.
