Carry out an investigation that uses patterns in growth rings in trees as indicators of environmental change. Analyze and interpret data that show changes in temperature over time scales of 1000 and 160,000 years. WebPaleoclimatology, the study of past climatic regimes (paleoclimates), has been expanding in scope in recent decades. One reason for this is the light thrown by paleoclimatic studies on the natural variability that exists in the Earth's climate in the context of future, anthropogenically influenced, climate changes.
