An Entropy Generation Rate Model for Tropospheric Behavior That Includes Cloud Evolution [PDF]

Entropy, 2023
A postulate that relates global warming to higher entropy generation rate demand in the tropospheric is offered and tested. This article introduces a low-complexity model to calculate the entropy generation rate required in the troposphere.
