Title: 'Irreversibility in the atmosphere on global and nanometre scales'.
Abstract: The atmosphere is in a nonequilibrium state and plays host to irreversible, entropy producing processes, two of which will be discussed. The first case concerns how the second law might be used to explain global temperature variation and remains rather speculative, but the second is much more rigorous and examines the generation of entropy during a nucleation process. We shall attempt to answer two questions. Does the atmosphere maximise entropy production, and does nucleation break the second law of thermodynamics?
