The Earth can be viewed as a system with a number of components — solid Earth, atmosphere, ocean, land-based hydrosphere. They interact with each other according to the natural physical laws related to quantities like energy, momentum, and mass, with water mass a special case. David will discuss this view, which has been recognized by climate scientists and those trying to make careful measurements using a number of different techniques.
