Description: Understanding the nature of the earth climate system and how it changes. Factors influencing climate including interactions among the atmosphere, oceans, and land surface processes. Sensitivity and feedback mechanisms of climate system. Past, present, and future climate. Forecasts future climatic change due to natural and anthropogenic variability.
