«since the mid 1980s a significant increase in visibility has been noted in western Europe (e.g. Doyle and Dorling, 2002), and there are strong indications that a reduction in aerosol load from anthropogenic emissions (in other words, air pollution) has been the dominant contributor to this effect, which is also referred to as «brightening».»

Well, to make it work, the mechanism needs clean air (which you always had over at least parts of the oceans) and nucleating aerosols (e.g., as you get from DMS, which is primarily formed by phytoplankton which exists for a loooooong while), so yes, it is reasonable that the mechanism has been operational, though quantitatively it may have changed somewhat.
