Research Statement

The earth's climate displays many tightly interwoven processes that cover vast scales in time and space. Clouds play a particularly vital role, by removing pollutants, and by acting as pistons in the atmospheric heat engine. But they are extraordinarily complex, so their relationship with climate remains largely mysterious. Is the problem fundamentally simple or impossibly complex? The Aerosol-Cloud-Climate Systems group I lead is trying to tease from clouds their importance to various atmospheric chemical, dynamic and radiative processes.

A second focus is development of a thermodynamic basis for interpreting the evolution of the global economy, and its relationship to atmospheric concentrations of carbon dioxide. Central to the model is the finding that civilization's economic value or wealth, when adjusted for inflation, is linked to its rate of primary energy consumption through a constant.
