In recent years, a lively controversy has existed regarding the sources contributing to variations of the total solar irradiance (TSI) on time scales of the magnetic activity cycle or longer. On one side are those who claim that the TSI variations can be explained entirely as a consequence of surface magnetic features (sunspots, faculae, and magnetic network). On the other side, a number of researchers claim that variations of the solar luminosity emerging from the solar interior, as a consequence of structural readjustments caused by the changing internal (dynamo) magnetic field, are important; and that indeed, they may dominate on those longer time scales.The case for the first viewpoint has been recently made in Eos [ Foukal, 2003]; the case for the second viewpoint is presented in this article.
