Soil colour has been inferred as an indicator of past climate.

With special reference to Jharkhand State of India . By Dr. Nitish Priyadarshi. Palaeoclimatology, the study of climates during the geological past, is one of the most topical areas research in the geoscience at present. The threat of future climate change caused by higher levels of greenhouse gases, which would drastically alter many aspects of our environment, has prompted much research to try to understand how our complex climate system works. Only by understanding how climate has evolved over million of years can we identify important cycles with a frequency in excess of the short climate records we possess. These climate cycles have the potential to have a profound effect on our environment. The determination of past climate parameters by the use of paleohydrologic conditions is an important phase of paleoclimatology. The present climate of any local area, on any continent, and around any lake basin, depends on the same factors which controlled Pleistocene climate. The study of p...
